The Project Management Institute (PMI) offers a certificate for people wanting to become a Project Management Professional (PMP). The institute, a not-for-profit professional organization, has been providing this opportunity since its creating in 1969. As with any well-credentialed professional organization, studies must be periodically completed to ensure the quality and usefulness of the services provided. Recommended for completion every 3 to 5 years, the PMI recently examined the field of project management in a Role Delineation Study (RDS). Based on this study, the PMI decided to alter the PMP exam, beginning in July 2013.
