Natural selection is possible because the best remain to build better species.
To be able to make changes, radical or not, it is important that at a certain point, all the stakeholders know clearly WHERE we are going, WHY we are going there, HOW we are going there, WHEN we are going there. It is important so we can get all the moral support we need but also we can get the distance we don't necessarily would have by receiving EVERYBODY's feedback.
I think it resumes well the importance of enhancing the strengths, involvement of all stakeholders and clear communication.
