Many organizations fail at agile transformations because they mix-and-match agile practices, or even ignore them completely. Agile frameworks often require acceptance of ideas and practices that are uncomfortable at first, but failing to embrace them in toto often results in failed adoptions that can directly affect the company's bottom line.
In an article from 2015, the Gartner group said:
Agile methods are highly systematic. Every component element of the methodology is crucial to the success of the methodology. A common mistake is for an organization to embrace some elements of an agile methodology, such as the sprint, but to ignore or play down other elements, such as managing "technical debt." Such organizations enjoy the kudos that comes from rapid development and release of new code, but they are storing up trouble by failing to address technical debt.
Successful transition of core business functions to an agile framework requires both a systematic approach and a deep understanding of the principles at work. Strong executive buy-in and a positive "tone at the top" is essential to gaining the benefits expected of your company's agile transformation.
