Almost twenty years have passed since the Agile Manifesto appeared. The legendary Robert Martin (Uncle Bob) realized that it was time to dust off the principles of Agile and re-talk about the flexible approach not only to a new generation of programmers, but also to specialists from other industries. The author of the books "Clean Code," "Ideal Programmer," "Clean Architecture" loved by IT specialists stood at the origins of Agile. "Pure Agile" eliminates misunderstandings and confusion that over the years of Agile's existence have complicated its application compared to its original intent.
