The short answer: no one.

When we are not the person who has decided the change, it automatically creates uncertainty. There are very few people who like uncertainty in their life.

When project managers decide to change their methods, it creates uncertainty. This uncertainty shows up as resistance to change: in you project team, your organization’s direction and your client.

As the project manager, it’s your job to communicate the change well:

  • Why are you changing your methods?
  • What is expected to be gain with this method?
  • What is the impact of the change on the team, the direction, the client?

Moreover, as the project manager, it’s your job to pay attention to how your stakeholders react to the change.

  • Are people “getting with the program?”
  • Is resistance getting stronger or weaker?

It’s important to be close to your team, direction and clients. It’s your responsibility to sell the change, and then make sure it brings the benefits you sold your stakeholders.
