The Pre-Mortem Mental Model: Anticipating Failure to Achieve Success

1. Introduction​

Imagine you're about to launch a crucial project, start a new business venture, or even embark on a significant personal goal. Excitement is in the air, plans are meticulously laid out, and optimism is high. But what if, despite all your best efforts, the project fails spectacularly? Instead of waiting for disaster to strike and then scrambling to understand what went wrong, what if you could travel into the future, witness the failure, and then come back to the present armed with invaluable insights to prevent it? This is the essence of the Pre-Mortem mental model, a powerful tool for proactive risk assessment and decision-making.

In our fast-paced, complex world, where unforeseen challenges and black swan events are increasingly common, relying solely on reactive problem-solving is no longer sufficient. We need to become proactive architects of our own success, anticipating potential pitfalls before they materialize. The Pre-Mortem, inspired by the medical field's post-mortem analysis, offers a structured and imaginative approach to do just that. It’s about shifting our perspective from hopeful planning to rigorous, failure-focused forecasting. By vividly imagining project failure before it happens, we unlock our ability to identify hidden risks, challenge assumptions, and build more robust plans.

Think of it as a mental time machine that allows you to fast-forward to a future where your project has gone awry. Instead of asking "How can we succeed?", the Pre-Mortem prompts you to ask, "Imagine our project has failed dramatically. What were the causes?" This simple yet profound shift in perspective can be transformative. It encourages open discussion, surfaces potential problems that might otherwise be overlooked, and ultimately, increases the likelihood of success. In essence, the Pre-Mortem is a proactive risk management technique where you assume a future failure to identify potential causes and mitigate them in advance. It's about learning from failures that haven't even happened yet, turning potential disasters into valuable learning opportunities.

2. Historical Background​

The Pre-Mortem technique, while seemingly intuitive, has its roots in the field of cognitive psychology and was formalized and popularized by Gary Klein, a renowned research psychologist specializing in naturalistic decision-making. Klein is not just an academic; he has spent decades studying how people make decisions in real-world, high-stakes environments, from firefighters battling blazes to military commanders in combat situations. His work emphasizes understanding decision-making in complex, uncertain, and time-pressured contexts, moving away from idealized rational models and towards how experts actually think.

Klein introduced the Pre-Mortem in a 1989 paper titled "Strategies of Decision Making" and further elaborated on it in his influential 2007 book, "Sources of Power: How People Make Decisions." His motivation for developing the Pre-Mortem stemmed from his observations of how teams often fall prey to groupthink, overconfidence, and a reluctance to voice dissenting opinions, especially when a project is gaining momentum. He noticed that while post-mortem analyses are valuable for learning from past mistakes, they are inherently reactive. He sought to create a proactive approach that could preemptively address potential problems.

Drawing inspiration from medical post-mortems, which are conducted after a patient's death to understand the cause, Klein flipped the concept. He reasoned that by simulating a "death" of a project before it begins, teams could proactively diagnose potential fatal flaws and prescribe preventative measures. This idea was grounded in the psychological principle of prospective hindsight, also known as the "knew-it-all-along effect." Prospective hindsight suggests that when people imagine an event has already happened, they are better able to identify the reasons why it might have occurred. By framing the scenario as a failure already realized, the Pre-Mortem leverages this cognitive bias to enhance foresight and risk identification.

Over time, the Pre-Mortem technique has gained traction beyond its initial applications in military and emergency response contexts. It has been adopted and adapted by various fields, including business management, software development, healthcare, and even personal development. Its simplicity and effectiveness have contributed to its widespread appeal. The core principles have remained consistent: envisioning failure, brainstorming causes, and developing preventative actions. However, the method has become more refined with practical guides, templates, and online tools emerging to facilitate its implementation in diverse settings. Today, the Pre-Mortem stands as a recognized and respected mental model for proactive risk management, a testament to its enduring value in enhancing decision-making and improving outcomes across various domains.

3. Core Concepts Analysis​

The Pre-Mortem mental model, at its heart, is about proactive problem identification through imagined failure. It's a structured brainstorming session designed to uncover potential weaknesses and risks within a plan or project before it's too late to address them. Let's break down the key components and principles:

1. Assumption of Failure: This is the cornerstone of the Pre-Mortem. Instead of starting with the usual optimistic outlook, the team is instructed to assume that the project or plan has already failed spectacularly. This is not about negativity; it's a deliberate and strategic shift in mindset. By starting from a point of failure, you bypass the natural human tendency to downplay risks or avoid uncomfortable conversations. It creates a psychologically safe space for team members to voice concerns and potential problems without fear of being perceived as pessimistic or unsupportive.

2. Brainstorming Causes of Failure: Once the assumption of failure is established, the next step is to brainstorm all the possible reasons why this failure might have occurred. This is a creative and collaborative process. Each team member, individually or collectively, thinks about the scenario and generates a list of potential causes. The goal is to be as comprehensive as possible, encouraging diverse perspectives and thinking outside the box. No idea is too outlandish at this stage. The brainstorming should cover a wide range of potential issues, including:

  • Technical failures: System glitches, design flaws, technological limitations.
  • Process failures: Inefficient workflows, communication breakdowns, poor planning.
  • Human factors: Lack of skills, miscommunication, interpersonal conflicts, burnout.
  • External factors: Market changes, competitor actions, regulatory shifts, unforeseen events (like a pandemic).
  • Resource constraints: Budget limitations, lack of time, insufficient personnel.
  • Strategic miscalculations: Incorrect assumptions about market demand, flawed business model, wrong target audience.

3. Prioritization and Analysis: After generating a comprehensive list of potential failure causes, the team needs to prioritize and analyze these risks. Not all risks are equally likely or equally impactful. The team should evaluate each identified cause based on:

  • Likelihood: How probable is it that this cause will actually contribute to failure?
  • Impact: If this cause does occur, how severe will its consequences be on the project?

This prioritization can be done using simple methods like voting or more structured approaches like risk matrices. The goal is to focus on the most critical and likely risks – the "vital few" that could truly derail the project. For each prioritized risk, the team should delve deeper into understanding the underlying mechanisms and potential cascading effects.

4. Development of Mitigation Strategies: The final crucial step is to develop concrete actions and strategies to mitigate or prevent the identified risks. This is where the Pre-Mortem transitions from diagnosis to prescription. For each significant risk, the team should brainstorm and document specific, actionable steps to reduce its likelihood or minimize its impact. These mitigation strategies might include:

  • Process improvements: Streamlining workflows, enhancing communication protocols, implementing better project management methodologies.
  • Contingency plans: Developing backup plans, creating buffer time, diversifying resources.
  • Skill development: Providing training, hiring experts, seeking external consultation.
  • Communication strategies: Establishing clear reporting lines, regular updates, proactive stakeholder engagement.
  • Technology upgrades: Implementing more robust systems, investing in better tools, conducting thorough testing.
  • Strategic adjustments: Refining the project scope, pivoting the approach, re-evaluating market assumptions.

Examples of Pre-Mortem in Action:

Example 1: Product Launch

Imagine a tech company preparing to launch a new mobile app. Instead of just celebrating the upcoming launch, they conduct a Pre-Mortem. They assume the app launch is a complete disaster – poor reviews, low downloads, negative media coverage. Brainstorming the causes, they might identify:

  • Technical glitches: Bugs in the app leading to crashes or poor user experience.
  • Marketing misfire: Ineffective advertising campaign, reaching the wrong target audience.
  • Competitive pressure: A similar, better app launching around the same time.
  • Lack of user onboarding: Confusing interface, poor tutorials leading to user frustration.
  • Scalability issues: Servers crashing due to unexpected high traffic.

For each risk, they develop mitigation strategies: rigorous beta testing to identify and fix bugs, targeted marketing campaigns, competitive analysis and differentiation, improved user onboarding tutorials, and robust server infrastructure planning. By proactively addressing these potential failure points, they significantly increase the chances of a successful app launch.

Example 2: Personal Goal - Starting a Blog

Let's say you decide to start a blog. A Pre-Mortem exercise might involve imagining your blog as a complete failure - no readers, no engagement, feeling demotivated and abandoning it. Brainstorming causes could reveal:

  • Lack of consistent content: Not posting regularly, losing reader interest.
  • Poor content quality: Unoriginal, unengaging, or poorly written content.
  • Ineffective promotion: Not reaching the target audience, no social media presence.
  • Technical challenges: Difficulties with website setup, design, or maintenance.
  • Time management issues: Underestimating the time commitment, getting overwhelmed.

Mitigation strategies could include: creating a content calendar, investing time in improving writing skills, learning SEO and social media marketing, choosing a user-friendly blogging platform, and scheduling dedicated blogging time. This Pre-Mortem helps you anticipate common blogging pitfalls and proactively set yourself up for success.

Example 3: Team Project at Work

Imagine a marketing team tasked with organizing a major online event. They conduct a Pre-Mortem assuming the event is a flop – low attendance, negative feedback, and failure to meet objectives. Potential causes could be:

  • Technical difficulties during the event: Platform crashes, audio/video issues.
  • Unengaging content: Boring presentations, lack of interactive elements.
  • Poor promotion and low registration: Not reaching the target audience effectively.
  • Speaker cancellations or no-shows: Disrupting the event schedule.
  • Lack of clear objectives and metrics: Difficulty measuring success or learning from the event.

Mitigation strategies might involve: thorough platform testing, engaging speaker briefings and content development, intensified marketing efforts, backup speaker arrangements, and clearly defined event objectives and success metrics. The Pre-Mortem helps the team proactively address potential event failures and ensure a more successful outcome.

These examples illustrate how the Pre-Mortem, through its core concepts of assuming failure, brainstorming causes, prioritizing risks, and developing mitigation strategies, can be applied across diverse contexts to enhance proactive planning and improve outcomes.

4. Practical Applications​

The Pre-Mortem mental model is remarkably versatile and can be applied across a wide spectrum of domains, both professional and personal. Its power lies in its proactive nature, allowing you to anticipate and mitigate potential problems before they arise. Here are five specific application cases across different areas:

1. Business Strategy & Project Management: In the business world, Pre-Mortems are invaluable for strategic planning, project management, and product development. Before launching a new product, embarking on a major marketing campaign, or implementing a new organizational structure, conducting a Pre-Mortem can surface hidden risks and assumptions. For example, a company planning a market expansion into a new geographical region could Pre-Mortem the expansion's failure. This might reveal risks like: underestimating local competition, misjudging consumer preferences, encountering regulatory hurdles, or logistical challenges. By identifying these potential pitfalls upfront, the company can adjust its strategy, conduct more thorough market research, build stronger contingency plans, and ultimately increase the likelihood of a successful expansion. In project management, Pre-Mortems can be integrated into project initiation and planning phases. Before kicking off a complex project, the team can Pre-Mortem its failure, uncovering potential risks related to scope creep, resource constraints, communication breakdowns, or technical challenges. This allows project managers to proactively address these risks by refining project plans, allocating resources more effectively, establishing clear communication protocols, and building in contingency buffers.

2. Personal Life & Goal Setting: The Pre-Mortem is not just for businesses; it's equally powerful for personal goal setting and life planning. When setting ambitious personal goals, like starting a new fitness regime, changing careers, or making a significant financial investment, a Pre-Mortem can help you anticipate obstacles and develop strategies for overcoming them. For instance, someone aiming to change careers could Pre-Mortem their career change failing. This might reveal risks such as: lack of necessary skills, difficulty networking in the new field, underestimating the learning curve, or facing financial strain during the transition. By anticipating these challenges, the individual can proactively address them by upskilling, building a professional network, creating a detailed learning plan, and establishing a financial safety net. Similarly, for personal projects like home renovations or event planning, Pre-Mortems can identify potential issues like budget overruns, timeline delays, material shortages, or logistical problems, enabling proactive planning and risk mitigation.

3. Education & Curriculum Design: Educators and curriculum designers can use Pre-Mortems to enhance the effectiveness of teaching programs and educational initiatives. Before launching a new course, implementing a new teaching methodology, or designing a new curriculum, a Pre-Mortem can help anticipate potential challenges and improve the design. For example, when designing a new online course, educators could Pre-Mortem its failure. This might reveal risks like: low student engagement, technical difficulties with the online platform, unclear learning objectives, inadequate support resources, or lack of effective assessment methods. By anticipating these issues, educators can proactively address them by designing engaging content, choosing a robust online platform, clarifying learning objectives, providing ample support, and developing effective assessment strategies. Pre-Mortems can also be used within student teams working on projects. Before starting a group assignment, students can Pre-Mortem the project's failure, identifying potential risks like: unequal contribution, communication breakdowns, conflicting ideas, or time management issues. This encourages proactive team agreements, clear roles and responsibilities, and communication plans to mitigate these risks.

4. Technology & Software Development: In the fast-paced world of technology and software development, Pre-Mortems are particularly valuable. Before launching a new software product, implementing a major system upgrade, or deploying a new technology infrastructure, conducting a Pre-Mortem can uncover potential technical, operational, and user-related risks. For example, a software company about to launch a new application could Pre-Mortem its launch failing. This might reveal risks like: software bugs, security vulnerabilities, scalability issues, poor user interface, or negative user reviews. By proactively identifying these potential problems, developers can prioritize rigorous testing, enhance security measures, plan for scalability, improve user interface design, and develop a robust post-launch support plan. In cybersecurity, Pre-Mortems can be used to anticipate potential security breaches. By imagining a successful cyberattack, security teams can brainstorm vulnerabilities in their systems, identify weaknesses in their security protocols, and proactively strengthen their defenses.

5. Healthcare & Patient Safety: The healthcare industry, with its critical focus on patient safety and error prevention, can greatly benefit from Pre-Mortems. Before implementing a new medical procedure, introducing a new medication protocol, or rolling out a new healthcare technology system, conducting a Pre-Mortem can help anticipate potential risks and enhance patient safety. For example, before implementing a new surgical procedure, a surgical team could Pre-Mortem the procedure going wrong. This might reveal risks like: equipment malfunctions, unexpected patient complications, communication errors in the operating room, or inadequate post-operative care protocols. By anticipating these potential issues, the team can proactively address them by ensuring equipment readiness, developing protocols for managing complications, enhancing communication within the surgical team, and establishing robust post-operative care plans. Pre-Mortems can also be used to analyze past medical errors or near-miss events. By retrospectively Pre-Morteming these events, healthcare professionals can identify systemic vulnerabilities and implement preventative measures to reduce the likelihood of similar incidents in the future.

These diverse application examples demonstrate the broad applicability of the Pre-Mortem mental model. Whether in business, personal life, education, technology, or healthcare, the core principle of proactively imagining failure to identify and mitigate risks remains consistently powerful and effective.

The Pre-Mortem mental model, while unique in its approach, shares common ground with other thinking tools that focus on risk assessment, planning, and decision-making. Understanding its relationships to these models helps clarify its specific strengths and when it's most effectively applied. Let's compare the Pre-Mortem with a few related mental models:

1. Inversion: Inversion is a powerful problem-solving technique that involves flipping a problem on its head. Instead of asking "How do I achieve success?", inversion asks "How do I avoid failure?" or "How do I make this worse?". While both Pre-Mortem and Inversion deal with negativity and failure, they approach it from slightly different angles. Inversion is a broader problem-solving technique applicable to various situations, while Pre-Mortem is more specifically focused on prospective risk assessment within projects or plans. Similarity: Both encourage thinking about negative outcomes. Difference: Inversion is a general problem-solving technique, while Pre-Mortem is a structured process for prospective failure analysis. Relationship: Pre-Mortem can be seen as a specific application of Inversion in the context of project planning. You are inverting the typical planning process by starting with the assumption of failure. When to choose Pre-Mortem: When you need a structured, team-based approach to proactively identify and mitigate risks within a specific project or plan. When to choose Inversion: When you are facing a complex problem and need a creative approach to reframe it and explore solutions from unconventional angles, not necessarily focused on project failure.

2. Second-Order Thinking: Second-Order Thinking emphasizes considering not just the immediate consequences of a decision (first-order effects), but also the subsequent effects that may arise as a result (second-order effects, third-order effects, and so on). It's about looking beyond the surface and anticipating the ripple effects of actions. Pre-Mortem and Second-Order Thinking both encourage deeper analysis and foresight, but they differ in their focus. Second-Order Thinking is about analyzing the consequences of actions, both positive and negative, while Pre-Mortem is specifically focused on anticipating the causes of a potential negative outcome (project failure). Similarity: Both encourage thinking beyond the immediate and considering downstream effects. Difference: Second-Order Thinking is broader, analyzing consequences of actions generally, while Pre-Mortem is focused on the causes of a specific negative outcome (failure). Relationship: Pre-Mortem can benefit from Second-Order Thinking. When brainstorming causes of failure in a Pre-Mortem, considering second-order effects can lead to identifying more nuanced and far-reaching risks. For instance, a first-order failure cause might be "marketing campaign misfire," but a second-order effect could be "damage to brand reputation and long-term customer trust." When to choose Pre-Mortem: When you need a structured process to proactively identify potential failure points in a project and develop mitigation strategies. When to choose Second-Order Thinking: When you need to make complex decisions and want to analyze the full spectrum of potential consequences, both positive and negative, across different time horizons.

3. Failure Modes and Effects Analysis (FMEA): FMEA is a systematic, proactive method for identifying potential failure modes in a system, process, or design, and analyzing their effects. It's commonly used in engineering and manufacturing to improve reliability and safety. FMEA and Pre-Mortem share the goal of proactive risk identification, but they differ in their methodology and scope. FMEA is a highly structured, quantitative, and often technical approach, involving detailed analysis of system components and processes. Pre-Mortem is more qualitative, imaginative, and focused on brainstorming and team discussion. FMEA is typically used for analyzing existing systems or designs, while Pre-Mortem is applicable during the planning phase of new projects or initiatives. Similarity: Both are proactive risk assessment techniques aimed at preventing failures. Difference: FMEA is highly structured, quantitative, and technical, while Pre-Mortem is more qualitative, imaginative, and team-based. FMEA analyzes systems and designs, while Pre-Mortem analyzes projects and plans. Relationship: Both aim to identify potential failures, but Pre-Mortem is a simpler, quicker, and more broadly applicable approach compared to the more rigorous and technical FMEA. In some cases, a Pre-Mortem might precede a more detailed FMEA. If a Pre-Mortem reveals critical areas of concern, an FMEA could be used to conduct a deeper, more technical analysis of those specific areas. When to choose Pre-Mortem: When you need a relatively quick, team-based, and broadly applicable method for proactive risk identification in projects or plans, especially in non-technical contexts. When to choose FMEA: When you need a highly structured, quantitative, and technically rigorous method for analyzing potential failure modes in systems, processes, or designs, often in engineering, manufacturing, or safety-critical applications.

In summary, while Pre-Mortem shares the spirit of proactive risk management with Inversion, Second-Order Thinking, and FMEA, it offers a unique blend of structured brainstorming, imaginative thinking, and team collaboration. It's particularly valuable when you need a practical, accessible, and engaging method to surface potential problems in projects and plans, fostering a culture of proactive risk awareness and improved decision-making. Choosing the right mental model depends on the specific context, the level of detail required, and the nature of the problem you are trying to solve.

6. Critical Thinking​

While the Pre-Mortem is a powerful mental model, it's crucial to approach it with critical thinking and awareness of its limitations and potential pitfalls. Like any tool, it can be misused or misinterpreted, leading to suboptimal outcomes if not applied thoughtfully.

Limitations and Drawbacks:

  • Overconfidence in Predictions: The Pre-Mortem relies on the team's ability to imagine and predict potential failure causes. However, even with the best efforts, there's always a risk of overlooking unforeseen factors or black swan events that were simply not imagined during the exercise. Teams might become overconfident that they have identified all major risks and develop a false sense of security.
  • Groupthink and Confirmation Bias: While Pre-Mortems are designed to encourage diverse perspectives, there's still a risk of groupthink, especially if the team culture is not truly open and psychologically safe. Dominant personalities might steer the brainstorming, or team members might self-censor dissenting opinions to maintain harmony. Confirmation bias can also creep in, where the team focuses on risks that align with their pre-existing beliefs or biases, while neglecting other potentially important threats.
  • Implementation Challenges: Identifying risks is only half the battle; effectively implementing the mitigation strategies is equally crucial. Pre-Mortems can sometimes generate long lists of risks and mitigation plans, but translating these plans into concrete actions and consistently following through can be challenging. If the Pre-Mortem process is not integrated into ongoing project management and monitoring, the identified risks and mitigation strategies might be forgotten or neglected over time.
  • Time and Resource Investment: Conducting a thorough Pre-Mortem requires time and resources. Gathering the team, facilitating the session, documenting the outcomes, and developing action plans all take effort. In fast-paced environments or resource-constrained projects, there might be a temptation to rush through the Pre-Mortem or skip it altogether, diminishing its effectiveness.
  • Potential for Negativity Bias: Focusing on failure can, in some cases, create a sense of negativity or pessimism within the team. If not facilitated carefully, a Pre-Mortem could inadvertently dampen enthusiasm or create unnecessary anxiety, especially if team members are already feeling stressed or uncertain about the project.

Potential Misuse Cases:

  • Performative Pre-Mortems: When Pre-Mortems are conducted merely as a formality, to tick a box, without genuine engagement or commitment from the team. If the exercise is treated as just another meeting rather than a serious opportunity for risk assessment, its value will be significantly diminished.
  • Blaming Exercises: If the Pre-Mortem devolves into a blame-storming session, where team members point fingers and attribute potential failures to individuals or departments rather than focusing on systemic risks. This can create a toxic environment and undermine the collaborative spirit of the exercise.
  • Analysis Paralysis: If the Pre-Mortem generates an overwhelming list of risks and mitigation strategies, leading to analysis paralysis, where the team becomes bogged down in planning and fails to take decisive action. It's crucial to prioritize risks and focus on the most critical mitigation strategies rather than trying to address every conceivable problem.
  • Using Pre-Mortem as a Substitute for Post-Mortem: Pre-Mortems are proactive, but they are not a substitute for post-mortem analysis after a project is completed (whether successful or unsuccessful). Post-mortems are essential for learning from actual experiences, validating or refuting the predictions made in the Pre-Mortem, and continuously improving future planning processes.

Advice on Avoiding Misconceptions and Misuse:

  • Emphasize Psychological Safety: Create a safe and open environment where team members feel comfortable voicing concerns and dissenting opinions without fear of judgment or reprisal. Clearly communicate that the Pre-Mortem is about proactive problem-solving, not about blame.
  • Facilitate Effectively: A skilled facilitator is crucial for guiding the Pre-Mortem session, keeping it focused, ensuring diverse participation, and preventing it from becoming negative or unproductive.
  • Focus on Actionable Outcomes: The Pre-Mortem should not be just a brainstorming exercise; it must lead to concrete action plans. Prioritize risks, develop specific mitigation strategies, assign responsibilities, and integrate these plans into project management processes.
  • Balance Proactive and Reactive Approaches: Pre-Mortems are valuable for proactive risk management, but they should be complemented by reactive problem-solving and continuous monitoring throughout the project lifecycle. Regularly review risks, adapt mitigation strategies as needed, and conduct post-mortems to learn from both successes and failures.
  • Regular Practice and Refinement: Like any skill, conducting effective Pre-Mortems improves with practice. Regularly incorporate Pre-Mortems into planning processes, and after each exercise, reflect on what worked well, what could be improved, and refine the process for future sessions.

By being mindful of these limitations and potential pitfalls, and by applying critical thinking to the Pre-Mortem process, you can maximize its benefits and avoid common misuse cases, making it a truly valuable tool for proactive risk management and improved decision-making.

7. Practical Guide: Conducting a Pre-Mortem​

Ready to put the Pre-Mortem mental model into practice? Here's a step-by-step guide to help you conduct an effective Pre-Mortem session, even as a beginner.

Step-by-Step Operational Guide:

1. Set the Stage (Preparation):

  • Define the Project/Plan: Clearly articulate the project, plan, or goal you're Pre-Morteming. Ensure everyone understands the objectives, scope, and key success metrics.
  • Assemble the Team: Gather a diverse group of stakeholders who have relevant knowledge and perspectives on the project. This might include project managers, team members, subject matter experts, and even representatives from different departments. Aim for 5-8 participants for optimal group dynamics.
  • Assign a Facilitator: Designate someone to facilitate the session. The facilitator's role is to guide the process, keep the discussion focused, ensure everyone participates, and manage time effectively.
  • Schedule the Session: Allocate dedicated time for the Pre-Mortem session, typically 1-2 hours, depending on the complexity of the project. Choose a time when team members are fresh and can focus without distractions.
  • Communicate the Purpose: Clearly explain the purpose and process of the Pre-Mortem to the team beforehand. Emphasize that it's a proactive, blame-free exercise aimed at improving project success.

2. Assume Failure (The "Time Travel"):

  • Set the Scenario: Start the session by vividly setting the scene. Imagine it's several months or years in the future (depending on the project timeline), and the project has failed spectacularly. Be dramatic and engaging. You might say something like: "Imagine it's [future date], and our project is a complete disaster. It's on the front page of the news for all the wrong reasons. We've missed our goals, wasted resources, and damaged our reputation."
  • Individual Reflection (Silent Brainstorming): Give each participant 5-10 minutes to silently brainstorm and write down as many reasons as they can think of why the project failed. Encourage them to think broadly and consider all potential categories of failure (technical, process, human, external, strategic, etc.).

3. Brainstorm Causes (Sharing and Discussion):

  • Round-Robin Sharing: Go around the room, and have each participant share one or two of their most significant failure causes. The facilitator should write these down on a whiteboard or shared document, grouping similar ideas together.
  • Open Discussion and Expansion: After the initial round, open the floor for discussion. Encourage team members to build on each other's ideas, ask clarifying questions, and add new potential causes. The facilitator should ensure everyone has a chance to contribute and that the discussion remains focused on identifying causes of failure, not assigning blame.
  • Categorize Causes (Optional): If the list of causes becomes extensive, you can categorize them into broader themes (e.g., technical risks, market risks, operational risks, etc.) to organize the information and identify patterns.

4. Prioritize Risks (Focus on the Vital Few):

  • Voting or Ranking: Have the team prioritize the identified failure causes. This can be done through simple voting (e.g., each person gets 3 votes to allocate to the most critical risks) or by ranking each cause based on likelihood and impact (using a scale of 1-5 for each).
  • Focus Discussion: Concentrate the discussion on the top 3-5 highest-priority risks – the "vital few" that are most likely to cause significant failure.

5. Develop Mitigation Strategies (Action Planning):

  • Brainstorm Solutions: For each prioritized risk, brainstorm concrete and actionable mitigation strategies. Ask: "What can we do now to prevent this failure from happening or to minimize its impact?"
  • Assign Ownership and Deadlines: For each mitigation strategy, assign a specific person or team responsible for implementation and set a realistic deadline.
  • Document Action Plan: Clearly document the prioritized risks, mitigation strategies, owners, and deadlines in a written action plan.

6. Review and Integrate (Ongoing Process):

  • Regular Review: Schedule regular follow-up meetings to review the action plan, track progress on mitigation strategies, and reassess risks as the project progresses.
  • Integrate into Project Management: Incorporate the Pre-Mortem findings and action plan into project plans, risk registers, and ongoing project management processes.
  • Post-Mortem Follow-up: After project completion (regardless of success or failure), conduct a traditional post-mortem to evaluate the effectiveness of the Pre-Mortem predictions and mitigation strategies, and to learn lessons for future projects.

Simple Thinking Exercise/Worksheet:

Scenario: Imagine you are planning a team picnic. Conduct a mini Pre-Mortem using the following worksheet:

Pre-Mortem Worksheet: Team Picnic Disaster

1. Assume Failure: Imagine our team picnic was a complete disaster. No one had a good time, and it was considered a failure.

2. Brainstorm Causes of Failure (List at least 5 reasons):

3. Prioritize Top 3 Failure Causes (Circle your top 3 from the list above):

4. Develop Mitigation Strategies for Top 3 Risks:

  • Risk 1 (from top 3): ________________________________________
    • Mitigation Strategy: _____________________________________
  • Risk 2 (from top 3): ________________________________________
    • Mitigation Strategy: _____________________________________
  • Risk 3 (from top 3): ________________________________________
    • Mitigation Strategy: _____________________________________

5. Action Items (Who is responsible for each mitigation strategy?):

  • Mitigation Strategy 1 Owner: ___________________________________
  • Mitigation Strategy 2 Owner: ___________________________________
  • Mitigation Strategy 3 Owner: ___________________________________

This simple exercise provides a hands-on way to understand and practice the Pre-Mortem process. By following these steps and practicing regularly, you can become proficient in using the Pre-Mortem mental model to proactively identify and mitigate risks in various projects and plans.

Frequently Asked Questions (FAQ)

1. Is a Pre-Mortem always necessary for every project? No, not necessarily. Pre-Mortems are most valuable for projects that are complex, high-stakes, novel, or involve significant uncertainty. For routine or low-risk tasks, a full Pre-Mortem might be overkill. However, even for smaller projects, considering potential failure points proactively is always beneficial, even if not in a formal Pre-Mortem session.

2. What if we can't imagine any way our project could fail? This is rare, but if it happens, it might indicate a lack of critical thinking or overconfidence. Encourage the team to dig deeper and think more broadly. Try changing the scenario to a more dramatic failure, or consider bringing in someone from outside the project team to offer a fresh perspective. Remember, no project is completely risk-free.

3. How often should we conduct Pre-Mortems during a long-term project? A Pre-Mortem is most effective at the project initiation or early planning stage. However, for long-term projects, it can be beneficial to conduct "mini" Pre-Mortems at key milestones or decision points to reassess risks and adapt mitigation strategies as the project evolves.

4. What's the difference between a Pre-Mortem and a Risk Assessment? Both are proactive risk management tools, but Pre-Mortem is a specific type of risk assessment. Traditional risk assessments often focus on identifying and analyzing risks based on historical data or expert opinions. Pre-Mortem uses imaginative thinking and the assumption of failure to uncover potentially overlooked risks, especially those related to systemic issues or unforeseen interactions. Pre-Mortem can be seen as a more creative and team-based approach to risk assessment.

5. What if our Pre-Mortem identifies too many risks? We feel overwhelmed! It's common to generate a long list of risks in a Pre-Mortem. The key is prioritization. Focus on the most likely and impactful risks – the vital few that could truly derail the project. Don't try to mitigate every single risk; concentrate on the most critical ones and develop actionable mitigation strategies for those.
