https://www.mcgill.ca/engineeringdesign/step-step-design-process/design-phases-mechanical-engineering/problem-definition   Problem Definition Problem definition is an essential initiating phase of any product development. In this phase you must understand existing problem, associating available data, images, and fundamental principles with it; generate strategies and methodology; critically evaluate state-of-the-art technologies, other machines and components available on the market.   Main steps of the problem definition Understanding the problem An essential requirement for an engineering design project is to formulate a problem precisely and to present a solution accurately. To formulate a problem, you must consider both real-time physical conditions (product shape, functional

Russia’s biggest problem isn’t the war. It’s losing the 21st century

When prominent members of the establishment break with the system, it often triggers a larger set of changes. Conversely, when you do not see such defection, it means the autocrat will probably be able to survive. (Syrian dictator Bashar al-Assad offers one example of this principle at work.)
