There are a wide range of Design Thinking methods and tools that can be used to help find a final solution, for example HCD (Human Centered Design) where the stages are prototyping, testing. , analyze and refine or the four-step iterative approach described by Marc Stickdorn (Stickdorn & Schneider, 2012) where the stages are: exploration, creation, reflection and implementation. Another idea might be to analyze the current planning system to identify good components that can be incorporated into a new system. The key point is that Design Thinking is an iterative process; if it doesn't work, try
