海外TECH	DEV Community	Agile or not Agile	https://dev.to/ivangavlik/agile-or-not-agile-28hn	Agile or not AgileOn the projects I ve worked on so far everyone implemented Agile ways of working or at least tried to I always found them not agile enough because things weren t as smooth as in books and tutorials there were always exceptions like longer sprintsreduced daily stand upslimited client involvementAnd then I realized just like there s no perfect clean code there s no perfectly by the book implemented way of agile working either so what s the secret then ProblemA lot of books and tutorials tend to overlook the fundamental essence of Agile in their focus on tools and methodologies They outline the steps the frameworks the processes but they miss the heart of what Agile truly represents It s not just about daily stand ups backlogs and sprints Back to the realityThe reality of projects is often messier with unexpected roadblocks changing priorities and unique team dynamics This made me realize that the key to successful Agile implementation isn t about sticking to a rigid formula it s about understanding the principles and creatively applying them to fit the context Just as clean code principles guide us towards writing maintainable and efficient code Agile principles guide us towards delivering value and responding to change effectively It s about finding that balance between structure and flexibility between following a plan and adapting to new insights So the secret lies in truly grasping the essence of Agileーembracing its values of collaboration communication and iteration It s about being agile in your thinking not just in your processes So here s my recipe for working in an agile way where are yourone step toward where you want to beevaluate and fix if broke For the endIn the end it s not about rigidly adhering to a specific set of rules but about applying the Agile mindset That s where the magic happensーwhere the tools and methodologies become vehicles for delivering impactful results and where each project s Agile journey becomes an authentic and dynamic story of adaptation and success	2023-08-23 22:06:21
