Explanation:
The fourth edition PMBOK defines Organizational Process Assets as any or all process related assets, from any or all of the organizations involved in the project that can be used to influence the projects success. Examples include: plans, procedures, lessons learned, historical information, schedules, risk data and earned value data. Organizational Process Assets fall into two broad categoriesProcesses and Procedures, and the Corporate Knowledge Base. The key concept is that these are assets a project manager may use for the benefit of the project. They work together with Enterprise Environmental Factors (EEFs) to bring those things outside the project team into focus.
