One of the main reasons for using internal project teams with end-to-end responsibilities that includes implementation instead of external consultants. Very often teams are more optimistic than actually warranted about the real buy-in and acceptance that they have created for their conclusions and recommendations. Environmental changes may make the agreed changes less attractive than originally believed. An example is if the success of an agreed change to a delivery process is dependent on a new product being launched, but the launch has been delayed.
