A lessons learned register is a document in which the project team records their valuable project experience. As a matter of fact, Project Management Body Of Knowledge (PMBOK) Sixth Edition has introduced a new process called “Manage ”. The Manage Project Knowledge process chiefly governs lessons learned in projects. The lessons-learned register is an important output of this process. Apart from other inputs, the lessons-learned register is also an input to this process.

Lessons Learned Register Process

Manage Project knowledge is one of the process of Project Integration Management Knowledge Area. In fact this new process is part of the Process Group and not Process Group. Moreover, this new process further defines project knowledge as both explicit and tacit.

Explicit Project Knowledge

According to PMBOK 6th edition, explicit knowledge is one that can be expressed using words or pictures. Explicit knowledge is shareable but lacks context and is open to interpretations. Even though explicit knowledge is shareable but it cannot be applied easily. Hence lessons-learned register is a tool that helps project teams to record explicit knowledge gained while executing a project.

Tacit Project Knowledge

On the other hand, tacit knowledge is personal and something that is difficult to express. Examples of tacit knowledge include personal experience, beliefs, etc. Tacit knowledge has context built into it but it cannot be represented as hard facts. It resides in minds of people and is normally shared during social interactions. Hence, PMBOK advocates networking as one of the tools in this process.

Therefore, manage project knowledge process achieves to integrate both explicit and tacit knowledge. Further, it provides a platform to document and share hard facts using various tools.

Hence, the knowledge management process drives two purposes. Firstly it enables organizations to apply existing knowledge. Secondly, it promotes an atmosphere of learning thereby enabling organizations to create a new knowledge base.

Project Management Lessons Learned Register

The lessons-learned register is an output of the Manage Project Knowledge Process. In fact, it is also one of the inputs to this process. Project team members should record lessons throughout project execution. Waiting to document the lessons towards the closing of the project results in a loss of information.

On completion of project activities, it is a good practice to archive lessons learned for use in future projects. This archive forms the Lessons Learned Repository for use in future similar projects. Such a learning repository should be easily accessible to each and everyone in the organization.

As a bare minimum requirement, the project team should document project lessons before closing the project or a project phase. While documenting project learnings it is essential that the document also supports the application of knowledge at a later date.

30 out of 49 either have lessons-learned register as input or output. 26 out of 30 processes have lessons-learned register as both input and output

The lessons-learned register is not an input but is an output of the following 3 processes.

  1. Estimate Activity Resources
  2. Acquire Resources
  3. Plan Procurement Management

The lessons-learned register is an input to but does not create an output from the following process.

  1. Collect Requirements

As shown above, the table establishes the importance of lessons learned in project management.

To sum up, documenting lessons and applying them in future projects should be an integral part of the organization's business process. Further, organizations should ensure that the lessons-learned register is accessible to all. It should also support easy recording and retrieval of project knowledge. Moreover, the use of this register should also facilitate the application of contextual knowledge in future projects. Organizations should also ensure that while documenting lessons the context around the knowledge is also understood. Creating an atmosphere of trust and motivation enhances sharing of project lessons.
