In thinking about your process for delivering innovative and impactful solutions, there are four commonly used frameworks and approaches for problem solving: Systems Thinking, Design Thinking, Lean, and Agile. Determining which framework to use is dependent on what you’re trying to accomplish. Also, I am framework-agnostic; I believe that each approach serves a specific purpose, many are complimentary, some have overlapping methods and most can be combined.
The big difference lies in understanding the focus and intended outcome for each method. For example, Systems Thinking and Design Thinking are complimentary frameworks, having some overlap in the area of understanding the present state of a system. The primary desired outcome for Design Thinking is to innovate and transform systems by addressing the question “What can be?” Systems thinking seeks to improve your understanding of complex systems by analyzing the broader context (time, space, interconnections) and to identify the solution that offers the highest leverage; it also addresses the question “What has been?”
The important thing is knowing what frameworks are available so that you can determine when and how it may support your work. Here’s a very high-level overview and cheat sheet for knowing when and how to think.
|Framework||Definition||Focus||When to use|
|Systems Thinking||To improve understanding of systems by thinking about the wider context of a situation, to uncover patterns and structures, to consider past and current state of systems.||Focusing on understanding complex systems and identifying opportunities for solving “root causes” to problems.||
|Design Thinking||To innovate and transform systems by addressing the question “What can be?” The design thinking process starts with defining the problem to be addressed, understanding the present state and then asking the question “what can be?” The design thinking process has the following stages: Empathize, Define, Ideate, Prototype and Test.||Focusing on discovering solutions with customer-centered problem solving.||
|Lean||A business methodology used to create more value for customers by using fewer resources and eliminating waste.||Focusing on improving the business model by relentlessly eliminating waste and delivering more value||
|Agile Methods||An approach to software development which emphasizes a continual planning, execution and delivery of working software.||Focusing on rapidly delivering working software solutions and continuously adapting to changing environments.||
