One of the key professional responsibilities of a project manager is contributing to the project management knowledge base. What does this mean?

In a nutshell, don’t keep your knowledge and experience locked in your brain. Share it!! 

• Share knowledge
• Research
• Build the capabilities of colleagues (i.e., teach, mentor, provide opportunities for your colleagues and your team members to build experience and knowledge)
• Advance the profession (engage in activities that will improve the overall PM profession; engage in activities that will promote the profession)
• Step up, at your own organization, to champion the value of project management. That is, playing a key role in the growth of PM within your organization
• Always record “lessons learned” at the end of a project or project phase; contribute to your organization’s organization process assets (OPAs). These 2 activities contribute to PM knowledge base and will help your colleagues during future projects
• Participate in PM forums, conferences and PMI chapter meetings
• Write articles

PMI expects PMPs to stay engaged with the profession.
