It's all about the results

On your journey towards organizational agility you will have to use many tools out of your toolkit.  You will use agile/lean models and practices, older models and practices, custom solutions, and common sense.  Organizational agility is about achieving the results not the means of getting those results.

Nobody is going to give you a gold star if you implement a purely agile solution.  There is no industry model that can be implemented out of the box to meet your organization's needs.  These models are a good start… But any transformation agent worth their weight does not stop there.  They involve this model in through numerous inspect and adapt cycles to constantly fit the context of your organization.
