Network Thinking: Weaving Connections for Clarity in a Complex World

1. Introduction

Imagine the world not as a collection of isolated objects, but as a vast, intricate tapestry woven with threads of relationships. This is the essence of Network Thinking, a powerful mental model that shifts your perspective from seeing individual pieces to understanding the connections between them. In a world increasingly defined by complexity, from global supply chains to social media ecosystems, Network Thinking offers a vital lens for navigating challenges and seizing opportunities. It's about recognizing that everything is interconnected, and that understanding these connections is key to effective decision-making.

In our daily lives, we often default to linear thinking, assuming cause-and-effect relationships are straightforward. However, reality is rarely linear. Network Thinking acknowledges the intricate web of dependencies that shape outcomes, encouraging us to look beyond surface-level explanations and delve into the underlying structures that drive systems. Whether you're strategizing in business, navigating personal relationships, or trying to understand global events, this mental model provides a framework for seeing the bigger picture. It helps you identify leverage points, anticipate unintended consequences, and ultimately, make more informed and impactful decisions.

At its core, Network Thinking is a mental model that defines systems as interconnected nodes (entities or actors) and edges (relationships or interactions) that form a network. It's a way of understanding how things are related to each other, how information and influence flow, and how the structure of these relationships shapes the behavior of the whole system. By adopting this model, you move from focusing on isolated parts to appreciating the dynamic interplay within the entire network, unlocking a deeper understanding of the world around you.

2. Historical Background

The roots of Network Thinking can be traced back to several intellectual movements, converging to form the interdisciplinary field we recognize today. While the explicit term "Network Thinking" might be relatively recent, the underlying concepts have been evolving for centuries, gaining significant momentum in the 20th century.

One crucial precursor is Systems Thinking. Pioneered in the mid-20th century by biologist Ludwig von Bertalanffy, Systems Thinking challenged reductionist approaches that broke down complex phenomena into isolated parts. Bertalanffy argued for understanding systems as wholes, where the interactions between components are as important as the components themselves. His work, outlined in "General System Theory," emphasized the interconnectedness and interdependence of elements within a system, laying the groundwork for understanding systems as networks. Systems Thinking provided the philosophical and conceptual basis for recognizing the importance of relationships and interactions, a core tenet of Network Thinking.

Simultaneously, the field of Cybernetics, founded by mathematician Norbert Wiener, explored the concepts of communication and control in complex systems, both biological and mechanical. Wiener's seminal work, "Cybernetics: Or Control and Communication in the Animal and the Machine," introduced ideas like feedback loops, self-regulation, and information flow within systems. These cybernetic principles are fundamental to understanding how networks function, adapt, and evolve. The focus on feedback and information exchange is directly relevant to analyzing how influence and change propagate through a network.

Another key influence comes from Graph Theory, a branch of mathematics dating back to the 18th century with Leonhard Euler's work on the Seven Bridges of Königsberg. Graph Theory provides the mathematical language and tools to represent and analyze networks. It offers a formal framework for describing nodes and edges, and for quantifying network properties like connectivity, centrality, and clustering. While initially a purely mathematical discipline, Graph Theory's applications expanded dramatically with the rise of computer science and the increasing availability of network data.

The late 20th and early 21st centuries witnessed an explosion of interest in networks across various disciplines, leading to the emergence of Network Science as a distinct field. Fueled by the internet, social media, and vast datasets, researchers from physics, sociology, computer science, and biology began to collaboratively study real-world networks. Figures like Albert-László Barabási, with his work on scale-free networks, and Duncan Watts, known for his contributions to small-world networks, became prominent in popularizing network concepts and demonstrating their broad applicability. Their research revealed universal patterns in diverse networks, from the internet and social networks to biological and economic systems.

The evolution of Network Thinking is thus a story of convergence. It's built upon the philosophical foundations of Systems Thinking, the control and communication principles of Cybernetics, and the analytical tools of Graph Theory. The rise of Network Science in recent decades has solidified Network Thinking as a powerful and versatile mental model, providing a framework for understanding and navigating the interconnected complexities of our modern world. It has moved from abstract theory to a practical toolkit for analyzing and intervening in diverse systems, making it an indispensable tool for anyone seeking to understand the dynamics of interconnectedness.

3. Core Concepts Analysis

Network Thinking, at its heart, is about dissecting and understanding the components and dynamics of networks. Let's break down the key concepts that form the foundation of this mental model:

• Nodes (Vertices or Actors): These are the fundamental building blocks of any network. Nodes represent the individual entities, objects, or actors within the system. Think of people in a social network, computers in the internet, cities in a transportation network, or neurons in the brain. Nodes can be anything that can be connected to something else. The characteristics of individual nodes can be important, but Network Thinking emphasizes their roles and relationships within the broader network.

• Edges (Links or Ties): Edges represent the connections or relationships between nodes. They describe how nodes are linked and interact. Edges can be physical connections (like roads between cities), social relationships (friendships between people), informational flows (links between websites), or dependencies (supply chain relationships between companies). Edges can be directed (one-way, like a follower relationship on social media) or undirected (two-way, like a friendship). The type and strength of edges are crucial for understanding network dynamics.

• Relationships: The nature of the connection represented by edges is paramount. Relationships can be diverse: friendship, professional collaboration, financial transaction, information exchange, biological interaction, or even physical proximity. Understanding the type of relationship is crucial for interpreting the network. For instance, a network of "mentions" on social media behaves differently from a network of "friendships." Analyzing the nature of relationships reveals the underlying dynamics and purpose of the network.

• Network Structure (Topology): This refers to the overall pattern of connections within the network. It describes how nodes and edges are arranged. Different network structures have distinct properties and behaviors. Common network structures include:

  • Centralized Networks: Highly connected to a central node (hub), like a star network.
  • Decentralized Networks: More evenly distributed connections, less reliance on a central hub.
  • Distributed Networks: No central control, highly resilient and redundant.
  • Scale-Free Networks: A few highly connected hubs and many nodes with few connections (common in real-world networks like the internet and social networks).
  • Small-World Networks: High local clustering (friends of friends are likely friends) and short average path lengths (most nodes are reachable from each other in a few steps).

• Feedback Loops: Networks are dynamic systems where actions and changes in one part can ripple through the entire structure, often in feedback loops.

  • Positive Feedback Loops (Reinforcing): Amplify changes, leading to growth or decline. Like viral marketing where more shares lead to even more shares.
  • Negative Feedback Loops (Balancing): Dampen changes, maintaining stability. Like a thermostat regulating temperature. Understanding feedback loops is crucial for predicting how networks respond to interventions or external shocks.

• Emergent Properties: Networks often exhibit properties that are not inherent in individual nodes but arise from the interactions and relationships between them. "The whole is greater than the sum of its parts." For example, the intelligence of an ant colony emerges from the interactions of individual ants, none of which are particularly intelligent on their own. Similarly, the resilience of the internet emerges from its distributed structure, not from the robustness of any single router. Emergent properties are often surprising and can be critical to understanding system-level behavior.

• Hubs and Centrality: In many networks, some nodes are more connected or influential than others. These are often called "hubs." Centrality measures quantify the importance or influence of nodes within a network. Different centrality measures exist, such as:

  • Degree Centrality: Number of direct connections a node has.
  • Betweenness Centrality: Number of shortest paths between other nodes that pass through a given node (nodes that act as bridges).
  • Closeness Centrality: Average distance from a node to all other nodes in the network (nodes that are close to everyone else). Identifying hubs and understanding centrality helps pinpoint key players and leverage points within a network.

• Clusters and Communities: Networks often exhibit clustering, where nodes are more densely connected to certain groups than to others. These clusters can represent communities, organizations, or groups of related entities. Identifying communities helps understand network segmentation and localized dynamics.

Examples to illustrate Network Thinking:

1. Social Network (e.g., Facebook):

   • Nodes: Individual user profiles.
   • Edges: Friendships, follows, likes, shares, comments.
   • Relationships: Social connections, information sharing, influence.
   • Network Structure: Scale-free, small-world (often).
   • Example Application: Analyzing information diffusion (viral content), identifying influential users (marketing), understanding community structures (group dynamics). Imagine a rumor spreading. Network Thinking helps you see how it propagates through connections, reaching certain clusters faster and being amplified by hubs (influencers).

2. Supply Chain Network:

   • Nodes: Companies, suppliers, distributors, retailers.
   • Edges: Flow of goods, money, information.
   • Relationships: Buyer-supplier, contractual agreements, logistical dependencies.
   • Network Structure: Complex, hierarchical, often vulnerable to disruptions.
   • Example Application: Risk assessment (identifying single points of failure), optimizing logistics (reducing bottlenecks), understanding supply chain resilience (adapting to disruptions). Consider a disruption like a port closure. Network Thinking allows you to trace the ripple effects through the supply chain, identifying which companies and industries are most affected and how to reroute flows.

3. Ecosystem (Food Web):

   • Nodes: Species of plants and animals.
   • Edges: Predator-prey relationships, symbiotic interactions.
   • Relationships: Energy flow, nutrient cycling, competition.
   • Network Structure: Complex, interconnected, often resilient but vulnerable to cascading effects.
   • Example Application: Conservation efforts (identifying keystone species), understanding ecosystem stability (response to environmental changes), predicting the impact of species extinction. Imagine the removal of a keystone predator. Network Thinking helps visualize how this disruption cascades through the food web, impacting prey populations and potentially leading to ecosystem collapse.

Through these examples, we see how Network Thinking provides a framework for analyzing diverse systems. By focusing on nodes, edges, relationships, and network structure, we can gain deeper insights into how these systems function, adapt, and evolve.

4. Practical Applications

Network Thinking is not just an abstract theoretical model; it's a highly practical tool with wide-ranging applications across diverse domains. By adopting a network perspective, we can unlock new insights and develop more effective strategies in various aspects of life and work. Let's explore five specific application cases:

1. Business Strategy and Market Analysis: In the business world, Network Thinking provides a powerful lens for understanding competitive landscapes and developing effective strategies.

   • Application: Analyzing industry ecosystems as networks of companies, suppliers, customers, and competitors. Mapping relationships like partnerships, investments, and customer flows. Identifying key players (hubs) and potential disruptions.
   • Analysis: By visualizing the market as a network, businesses can identify strategic opportunities, such as forming alliances, targeting influential players, or exploiting network vulnerabilities of competitors. For example, understanding the network of relationships in the smartphone industry can reveal the power dynamics between manufacturers, component suppliers, and software platforms, informing a company's entry or expansion strategy. Network analysis can also help identify emerging trends by tracking information flow and identifying clusters of innovation within the industry network. Furthermore, understanding customer networks can inform targeted marketing campaigns and improve customer retention.

2. Personal Relationship Management and Social Navigation: Our personal lives are inherently networked. Network Thinking can improve our understanding of social dynamics and enhance our relationship management skills.

   • Application: Mapping your personal social network – family, friends, colleagues, acquaintances. Analyzing the strength and type of connections. Identifying network gaps and opportunities for building stronger relationships. Understanding information flow and influence within your network.
   • Analysis: By visualizing your social network, you can identify key support systems, potential sources of information or opportunities, and areas where you might need to strengthen connections. For instance, if you're seeking a career change, analyzing your professional network can reveal potential connections to relevant industries or companies. Understanding the structure of your social network can also help you navigate social situations more effectively, identify potential conflicts, and build stronger, more supportive relationships. It can also help you understand how information and ideas spread within your social circles.

3. Education and Collaborative Learning: Network Thinking can revolutionize educational approaches by emphasizing interconnected learning and fostering collaborative environments.

   • Application: Designing curricula that highlight interdisciplinary connections and real-world applications. Fostering collaborative learning environments where students learn from each other and build knowledge networks. Using network analysis to understand student interactions and identify learning communities.
   • Analysis: By structuring education around network principles, educators can move beyond rote memorization to encourage deeper understanding and critical thinking. Designing projects that require students to collaborate and build upon each other's knowledge creates a learning network where knowledge is distributed and co-created. Analyzing student interaction networks in online learning platforms can reveal patterns of collaboration, identify students who might be isolated, and inform interventions to foster a more connected and supportive learning environment. This approach promotes a more engaging and effective learning experience, preparing students for a networked world.

4. Technology and Cybersecurity: The digital world is fundamentally built on networks. Network Thinking is essential for understanding and managing technological systems, particularly in cybersecurity.

   • Application: Analyzing computer networks to identify vulnerabilities and improve security. Understanding the spread of viruses and malware through networks. Designing resilient and decentralized systems. Analyzing social media networks for misinformation and cyber threats.
   • Analysis: By visualizing network infrastructure, cybersecurity professionals can identify critical nodes and potential points of failure. Understanding network topology helps in designing robust security measures and detecting anomalies that might indicate cyberattacks. Network analysis is also crucial for tracking the spread of misinformation and malicious content online, and for developing strategies to counter these threats. The principles of Network Thinking are fundamental to building secure, resilient, and trustworthy digital systems.

5. Urban Planning and City Management: Cities are complex networks of infrastructure, people, and services. Network Thinking provides valuable tools for urban planners and city managers.

   • Application: Analyzing transportation networks (roads, public transit) to optimize traffic flow and improve accessibility. Understanding the flow of resources (water, energy, waste) within a city. Analyzing social networks within communities to inform urban development and social programs.
   • Analysis: By mapping urban networks, planners can identify bottlenecks in transportation, optimize resource allocation, and improve the efficiency and sustainability of city operations. Understanding social networks within communities helps in designing urban spaces that foster social interaction and community cohesion. For example, analyzing pedestrian traffic flow networks can inform the design of pedestrian-friendly zones and improve walkability. Network Thinking helps create more livable, efficient, and resilient urban environments.

These examples demonstrate the versatility of Network Thinking. By shifting our perspective to focus on connections and relationships, we can gain deeper insights and develop more effective strategies across a wide spectrum of domains, from business and personal life to education, technology, and urban development.

5. Comparison with Related Mental Models

Network Thinking, while powerful, is not the only mental model that helps us understand complex systems. It shares common ground with other models, but also has distinct characteristics. Let's compare it with two closely related mental models: Systems Thinking and Complexity Theory.

Network Thinking vs. Systems Thinking:

• Similarities: Both emphasize interconnectedness, relationships, and understanding the whole system rather than isolated parts. Both recognize emergent properties and feedback loops. Both arose from similar intellectual roots (cybernetics, general systems theory).
• Differences: Systems Thinking is a broader, more overarching framework that emphasizes holistic understanding and system dynamics. Network Thinking is a more specific and analytical approach within Systems Thinking. Network Thinking provides a more concrete toolkit for analyzing system structure using network concepts (nodes, edges, centrality, etc.). Systems Thinking focuses more on system behavior and dynamics, while Network Thinking emphasizes the underlying structure that shapes that behavior.
• Relationship: Network Thinking can be seen as a tool or methodology within the broader framework of Systems Thinking. It provides a specific way to operationalize Systems Thinking principles by focusing on network structures.
• When to Choose: Use Systems Thinking when you need a broad, holistic understanding of a complex situation, focusing on system boundaries, feedback loops, and overall dynamics. Choose Network Thinking when you want to analyze the specific relationships and connections within a system, identify key players, and understand how structure influences behavior. If Systems Thinking is the map, Network Thinking is the compass and tools to navigate the terrain.

Network Thinking vs. Complexity Theory:

• Similarities: Both deal with complex systems, emergence, and non-linear dynamics. Both acknowledge that simple causes can have complex effects, and vice versa. Both recognize the importance of interactions and feedback loops in shaping system behavior.
• Differences: Complexity Theory is a broader field that studies complex systems in general, including chaotic systems, self-organizing systems, and adaptive systems. Network Thinking is a more specific approach that focuses on the network structure as a key aspect of complexity. Complexity Theory often deals with broader concepts like emergence, adaptation, and phase transitions, while Network Thinking provides specific tools for analyzing the architecture of complex systems.
• Relationship: Network Thinking is often used as a tool within Complexity Theory to analyze the structure of complex systems. Network analysis can reveal emergent patterns and properties in complex systems that are studied by Complexity Theory. Complexity Theory provides a wider theoretical framework for understanding complex phenomena, while Network Thinking offers a specific methodology for investigating the relational aspects of complexity.
• When to Choose: Use Complexity Theory when you are interested in understanding the general principles of complex systems, such as emergence, adaptation, self-organization, and unpredictability. Choose Network Thinking when you want to specifically analyze the relational structure of a complex system, understand how connections influence behavior, and identify key nodes or pathways. Complexity Theory helps you understand why systems are complex, while Network Thinking helps you understand how that complexity is structured and operates through networks of relationships.

In summary, while Systems Thinking and Complexity Theory provide broader frameworks for understanding complex systems, Network Thinking offers a more focused and analytical lens, emphasizing the importance of relationships and network structure. Network Thinking is often a valuable tool within both Systems Thinking and Complexity Theory, providing a concrete methodology for analyzing and understanding the interconnectedness that lies at the heart of complex systems. Choosing the right model depends on the specific problem and the level of detail required. Often, a combination of these mental models provides the most comprehensive and insightful approach to navigating complexity.

6. Critical Thinking

While Network Thinking is a powerful mental model, it's crucial to approach it with critical awareness of its limitations and potential pitfalls. Like any tool, it can be misused or misapplied, leading to inaccurate conclusions or ineffective actions.

Limitations and Drawbacks:

• Oversimplification: Network models, by their nature, are simplifications of reality. Focusing solely on nodes and edges can sometimes lead to neglecting important contextual factors, qualitative aspects, and nuances of relationships. Reducing complex interactions to binary connections (present or absent) or simple weights can lose valuable information. Real-world relationships are often multifaceted and dynamic, changing over time and context, which can be challenging to capture in static network representations.
• Data Dependency and Bias: Network analysis heavily relies on data about relationships. The quality and completeness of this data are crucial. Incomplete or biased data can lead to skewed network representations and misleading conclusions. For example, social network data from online platforms may not accurately reflect real-world social connections, and may be biased towards certain demographics or types of interactions. Data collection itself can also introduce biases, influencing the network structure observed.
• Focus on Structure, Neglecting Agency: Network Thinking can sometimes overemphasize the structural constraints of networks and underemphasize the agency of individual nodes. While network structure shapes behavior, individuals and organizations within networks are not passive actors. They can actively shape and reshape their networks, influencing relationships and creating new connections. A purely structural view might miss the dynamic interplay between structure and agency.
• Difficulty in Defining Boundaries: Defining the boundaries of a network can be challenging. Where does a network begin and end? Choosing inappropriate boundaries can lead to incomplete or misleading analysis. For example, analyzing a company's supply chain network requires defining which suppliers and customers to include, and how far upstream and downstream to extend the network. Boundary definition is often subjective and can significantly impact the results of network analysis.
• Static vs. Dynamic Networks: Many network analysis techniques are applied to static snapshots of networks. However, real-world networks are often dynamic, constantly evolving and changing over time. Analyzing static networks can miss important dynamic processes, such as network evolution, relationship formation and dissolution, and the spread of influence over time. Analyzing dynamic networks requires more sophisticated methods and data.

Potential Misuse Cases:

• Conspiracy Theories and Echo Chambers: Network Thinking can be misused to create or reinforce conspiracy theories. By selectively highlighting certain connections and ignoring others, it's possible to construct network diagrams that seem to "prove" hidden agendas or secret cabals. Similarly, social media algorithms can create echo chambers by reinforcing existing connections and limiting exposure to diverse perspectives, leading to polarized network structures and biased information flow.
• Manipulation and Exploitation: Understanding network structures can be used for manipulative purposes, such as targeted advertising, social engineering, or political propaganda. Identifying influential nodes (hubs) can be used to disproportionately target them with information or influence campaigns, potentially manipulating network behavior for specific agendas.
• Over-reliance on Quantifiable Metrics: Network analysis often relies on quantifiable metrics like centrality and density. Over-reliance on these metrics can lead to neglecting qualitative aspects of relationships and focusing solely on easily measurable but potentially less meaningful network properties. It's important to remember that numbers don't always capture the full complexity of human interactions and social systems.

Advice to Avoid Misconceptions:

• Context is Key: Always consider the context when applying Network Thinking. Network analysis is not a standalone solution but a tool to be used in conjunction with other analytical methods and domain expertise. Understand the specific context of the network being analyzed and interpret network metrics within that context.
• Data Validation and Triangulation: Critically evaluate the data used for network analysis. Validate data sources, check for biases, and triangulate findings with other sources of information. Don't rely solely on network diagrams or metrics; ground your analysis in real-world observations and qualitative insights.
• Focus on Interpretation, Not Just Metrics: Don't get lost in the numbers. Focus on interpreting the meaning of network metrics and patterns in the context of the system being studied. Ask "so what?" questions. What do these network patterns tell us about the system's behavior, vulnerabilities, or opportunities?
• Acknowledge Agency and Dynamics: Remember that networks are not static and deterministic. Acknowledge the agency of actors within networks and the dynamic nature of relationships. Consider how networks evolve over time and how actors can shape and reshape their connections.
• Ethical Considerations: Be mindful of the ethical implications of network analysis, particularly when dealing with social networks or personal data. Use network insights responsibly and avoid manipulative or exploitative applications. Respect privacy and data security.

By being aware of these limitations and potential pitfalls, and by applying critical thinking, we can use Network Thinking effectively and responsibly, leveraging its power while mitigating its risks. It's about using it as one tool in a broader toolkit for understanding complexity, rather than as a definitive or infallible solution.

7. Practical Guide: Applying Network Thinking

Ready to start applying Network Thinking in your daily life and work? Here's a step-by-step guide to get you started, along with a simple thinking exercise:

Step-by-Step Operational Guide:

1. Identify the System: Clearly define the system you want to understand. What are you trying to analyze? (e.g., your professional network, the market for a product, the flow of information in your organization). Define the boundaries of your system - what's included and what's excluded?

2. Identify Nodes: Determine the key entities or actors within your system. What are the "things" that are connected? (e.g., people, companies, websites, ideas, departments). List out the key nodes in your system.

3. Identify Edges and Relationships: Determine the connections or relationships between the nodes. What kind of relationships exist? (e.g., friendship, collaboration, financial transactions, information flow, influence). Map out the edges between your nodes. Consider the type and strength of relationships. Are they strong or weak ties? Are they directed or undirected?

4. Visualize the Network (Optional but Highly Recommended): Create a visual representation of your network. You can use pen and paper, whiteboards, or network visualization software (like Gephi, NodeXL, or even simple online tools). Visualizing the network can help you see patterns and structures that might be difficult to grasp from a list of nodes and edges. Even a simple hand-drawn diagram can be insightful.

5. Analyze Network Structure: Examine the overall structure of your network. Is it centralized or decentralized? Are there clusters or communities? Are there any obvious hubs or bridges? Look for patterns and structures.

   • Identify Hubs: Are there nodes with many connections (high degree centrality)? Are there nodes that connect different parts of the network (high betweenness centrality)? Who are the key players?
   • Identify Clusters: Are there groups of nodes that are more densely connected to each other than to the rest of the network? What are these clusters, and what do they represent?
   • Look for Feedback Loops: Can you identify any feedback loops in the network? How do actions and changes in one part of the network ripple through the system?

6. Interpret and Draw Insights: Based on your network analysis, what insights can you draw about the system? What are the implications of the network structure? How does the network structure influence behavior, outcomes, or vulnerabilities? What are the leverage points for intervention or change?

7. Test and Iterate: Network Thinking is an iterative process. Your initial network representation may be incomplete or inaccurate. Test your assumptions, gather more data if needed, and refine your network model as you learn more. Continuously update your network understanding as the system evolves.

Simple Thinking Exercise: Map Your Professional Network

1. Nodes: Think about the key people in your professional life – colleagues, supervisors, mentors, clients, collaborators, industry contacts. List at least 10-15 people who are relevant to your professional goals or current work. These are your nodes.

2. Edges & Relationships: Consider the relationships you have with each person on your list. Are they strong ties or weak ties? What type of relationship is it (e.g., direct supervisor, project collaborator, industry contact, mentor)? Draw lines (edges) connecting people you know and interact with professionally. You can use different line thicknesses or colors to represent different types or strengths of relationships.

3. Visualize: Create a simple visual map of your professional network. Put yourself in the center (optional) or just map the connections between the people you listed.

4. Analyze: Look at your network map.

   • Hubs: Are there any people in your network who seem to be very well-connected (hubs)?
   • Clusters: Are there clusters of people who are connected to each other but less connected to others in your network?
   • Gaps: Are there any areas where you have few connections? Are there any "bridges" connecting different clusters?
   • Your Role: What is your position in the network? Are you centrally located, or more peripheral?

5. Insights and Action: What insights did you gain from mapping your professional network? Are there any connections you should strengthen? Are there any network gaps you should try to fill? Are there any hubs you should connect with? How can you leverage your network to achieve your professional goals? Think about 1-2 actionable steps you can take based on your network analysis.

Worksheet Idea (Simple Table):

Node (Person/Entity)	Connected to (Node Name)	Type of Relationship	Strength of Relationship (Strong/Weak)	Notes/Context
Your Name	Colleague A	Project Collaboration	Strong	Working on project X together
Your Name	Mentor B	Mentorship	Strong	Regular mentorship meetings
Colleague A	Client C	Client Relationship	Medium	Client for project X
...	...	...	...	...

This exercise is a starting point. As you become more comfortable with Network Thinking, you can apply it to more complex systems and use more sophisticated network analysis tools. The key is to start practicing, observing connections, and thinking in terms of relationships and networks.
