people skills. And it’s true that a project management methodology like Prince 2 or PMI will
emphasize the importance of addressing people issues such as commitment building and
managing resistance, and will naturally include deliverables such as training and communication
plans.
However, project management methodologies offer little practical guidance in how to
motivate and mobilize people to change. Most project managers will spend the majority of their
time worrying about practical issues with deliverables and timelines, not the people risks of the
change process. It is these people-focused skills that will determine the success of a project and
ensure effective implementation, not just installation. They are essential to ensure that lasting
change takes place in an organization.
It’s vital for an organization to acquire these skills, either by helping project managers to
develop them, or by building a dedicated change management function that works closely with
the project management function. By combining project and change capabilities in key people
and teams, you can create real change champions: a force for positive change in an organization.
