What's the difference between a Project Manager and a DRI?

When it comes to major strategic activities or initiatives involving multiple projects, a DRI is necessary for success. This can be someone with organizational responsibilities or the potential to possess strong DRI characteristics. The DRI's role involves strategically and innovatively bringing the initiative to fruition, while a project manager is responsible for setting the pace and handling logistics. While the same person can fulfill both roles, it's best to have separate individuals closely partnering for successful results.
