“Growth is not linear and it doesn’t happen in discrete phases marked by convenient external characteristics” — which is why maturity models are wrong — according to Christiaan Verwijs, specifically looking at agile models.
“Of course, maturity models are meant to simplify the complexities of reality. But what is gained by squeezing such a messy, non-linear thing as the professional growth of individuals, teams, and organisations into an easily digestible model that allows us to feel like we’re making decisions based on something tangible? Oh, wait ….
Maturity models are the best friend of consultants. They are easy to understand and may seem very profound at first. It’s an easy way to make a good impression. This makes them excellent snack food for consultants, and for the organisations that are looking for easy answers to their complex problems.” —CV
Are maturity models useful? Is there a more useful model we could use?
“Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful.” —George Box
