Agile/Scrum is the current buzzword for obvious reasons, such as its self-organized teams and its empowered, motivated individuals working toward a common goal. Miracles are bound to happen.
But to realize the real benefits of Scrum, the transformation of the team should be complete in all aspects.
Successful transformation to Agile depends mainly on the following two important factors:
Willingness to be Agile
Ability to be Agile
There is a famous saying: "Where there is a will, there is a way." This holds true for an Agile transformation. It means that when the team members are convinced and willing to be Agile, then nothing can stop them from being Agile. Agile is more of a mind-set than a method.
Hence our focus should on the willingness aspect rather than the ability aspect. When you are willing, then lack of ability won't be a problem, as there are many ways of gaining ability.
Conversely, if we focus more on ability, then Scrum will become more like a Waterfall exercise, as the ScrumMaster must play the role of manager, forcing team members to follow the Scrum method. All the Scrum ceremonies will be more ritual than creation of real value. Since Agile is a mind-set, then ability only, without willingness, can never yield the desired results and will do more harm than good.
