TOPIC: PMIS vs OPA

Hi,

In the chapter 4 of the PMBOK it starts to describe the Project Management Information System - PMIS which, as per description, presents many correlations with or within Organizational Process Assets - OPA. However, the PMBOK does not explicit any correlation between both, neither the lesson "L04.03: Direct and Manage Project Work - Part 2" . What is the relationship between PMIS and OPA? Is PMIS part of OPA or completely different things?

Thank you everybody in advance that could help me out clarify this!

As I understand it, a PMIS is a particular item - the generic name for project management software, document libraries, collaboration tools etc, whatever is used in your business. OPA is a group of organisational assets that is much broader and includes lots of items. OPAs might not be for managing project management information, they might simply be other assets from around the business.
