Einstein famously quoted: “…We cannot solve our problems with the same thinking we used when we created them….”. Einstein recognized that the thinking or mindset that led to the creation of a problem may not be sufficient to find a solution. If we continue to approach problems with the same mindset, we are likely to get stuck in a loop of repeating the same actions and expecting different results, which Einstein famously referred to as "insanity." This quote emphasizes the need for innovation and new perspectives in problem-solving. To solve problems effectively: we suggest that you need to shift your perspective, think differently, and adopt new ways of understanding and approaching complex problems. This involves examining the underlying assumptions, questioning established beliefs, and seeking innovative solutions. This book (which is the first in a series of 4) aims to provide a starting point to envision problems differently and support the reader in adapting his-/hers ways in finding the optimal solution and implementing them. This book is aimed at everyone who deals with solving problems on a day to day basis and is looking for a support structure that enables the reader to capture the optimal solution and creates ways forwards for realizing them.
