How do you simplify complex systems?

1 Identify the essentials

The first step to simplify complex systems is to identify the essential elements and functions of your system. These are the core components that define your system's purpose, value, and identity, and that cannot be removed or changed without compromising your system's functionality or quality. To do this, you can use tools such as stakeholder analysis to identify key users, customers, beneficiaries, or influencers of your system and determine their needs, expectations, and goals. Additionally, you can use a value proposition to define the unique benefits and advantages that your system provides to stakeholders, as well as a system boundary to determine inputs, outputs, and constraints of your system. It is also important to consider external factors or influences that affect your system.

2 Reduce the noise

The second step to simplify complex systems is to reduce the unnecessary complexity and noise. These are the elements or functions that add little or no value, create confusion, ambiguity, or inefficiency. To reduce this complexity and noise, you can use tools such as Pareto analysis to identify the 20% of elements that contribute to 80% of your system's value, and Occam's razor to choose the simplest solution among multiple alternatives. Additionally, following the KISS principle by making your system as simple as possible can help avoid overcomplicating or overengineering it.

3 Use abstraction and decomposition

The third step to simplify complex systems is to use abstraction and decomposition to break down your system into manageable parts. Abstraction involves focusing on the relevant or high-level concepts or features of your system, while decomposition involves dividing your system into smaller and simpler sub-systems or modules with a clear and specific function or responsibility. To use abstraction and decomposition to simplify your system, you can use tools such as a conceptual model, a hierarchical structure, and functional decomposition. A conceptual model can create a simplified representation or diagram of your system, showing the main concepts, relationships, and flows. A hierarchical structure organizes your system into levels that represent different levels of abstraction or detail, while functional decomposition breaks down your system into smaller and simpler sub-systems or modules.

4 Apply feedback loops and metrics

The fourth step to simplify complex systems is to apply feedback loops and metrics to monitor and adjust your system. Feedback loops allow your system to receive and respond to information from its environment, components, or stakeholders, while metrics measure the performance, reliability, and efficiency of your system. To achieve this, you can use SMART goals to set specific, measurable, achievable, relevant, and time-bound goals for your system. Additionally, a balanced scorecard can be used to monitor and measure the performance of your system from four perspectives: financial, customer, internal, and learning and growth. Finally, the PDCA cycle can be used to implement continuous improvement in your system by planning actions based on goals and metrics, doing them according to the plan, checking results against metrics, and acting on findings to adjust the plan or actions.

5 Leverage modularity and reusability

The fifth step to simplify complex systems is to leverage modularity and reusability to enhance scalability and flexibility. Modularity allows for independent and interchangeable sub-systems or modules, each with a specific function or responsibility, while reusability enables existing sub-systems or modules to be reused by other systems without significant changes. To leverage these properties, you can employ tools such as interface design, a component library, and design patterns. Interface design defines the inputs, outputs, and protocols that enable communication and coordination between sub-systems or modules. A component library contains developed or acquired sub-systems that can be reused or integrated into other systems. And design patterns apply proven and reusable solutions to common problems or challenges in your system. All of these tools help to simplify your system's structure, behavior, and interactions.

6 Adopt a systems thinking mindset

The sixth and final step to simplify complex systems is to adopt a systems thinking mindset to understand and improve your system as a whole. Systems thinking is an approach that views your system as a dynamic and complex entity, rather than a collection of isolated and static parts. This strategy helps you recognize the interrelationships and interdependencies among your system's elements and functions, anticipate the consequences of your actions, adapt to changing environments, and learn from feedback loops and metrics. By adopting a systems thinking mindset, you can simplify complex systems by seeing the big picture, finding the leverage points, and creating the desired outcomes.
