Lessons Learned Register
Lessons Learnt Register

A lessons learned register is a document in which 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 Project Knowledge”. 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 Executing Process Group and not Closing 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 for 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 in to 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 the tool 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 organisations to apply existing knowledge. Secondly, it promotes an atmosphere of learning thereby enabling organisations to create new knowledge base.

Project Management Lessons Learned Register

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

On completion of project activities it is a good practice to archive lessons learned register for use in future projects. This archive forms Lessons Learned Repository for use in future similar projects. Such learnings repository should be easily accessible to each and every one in the organisation.

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 application of knowledge at a later date.

30 out of 49 project management process either have lessons learnt register as input or output. 26 out of 30 processes have lessons learnt register as both input and output

The lessons learnt register is not an input to but is an output of the following 3 processes.

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

The lessons learnt 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 register in project management.

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