The lessons learned processWhy organisations use change managers
The lessons learned process is a structured approach designed to help project teams capture, document, analyse, and utilise valuable insights from past experiences.

Key questions to ask
Facilitating deliberations can be guided by using the following essential questions:£799 +vat
- What went well in the project?Starting a change manager career
- What challenges did we face?Experience
- How did we overcome these challenges?Firstly, you probably need to have at least on-the-job experience in a management role in a corporate environment. The reason for this is because it helps you understand the complexity of individuals, teams, and senior leaders’ issues. You will need to know how to mediate between these different people and their departments’ needs to achieve the change you are assigned to.
- What would we do differently next time?If you are in an entry level or junior position, you can check if your organisation offers change agent roles. These roles will help you comprehend and take part of the change process and eventually gain experience in the change cycle.
- What unexpected events occurred, and how did we handle them?Domain knowledge
By focusing on these questions, you can elicit valuable insights from your team members. Remember to create an environment where all participants feel comfortable and safe to share their experiences and observations.In addition to that, industry knowledge is important. You are expected to at least know the products and services your company sells and reflect that in your change plan. A fashion house will be different from a car selling company, for example. The internal and external structure of both are completely different and should be taken into consideration.
By investing time and effort into thoroughly preparing and skilfully facilitating lessons learned sessions, you will be able to generate a wealth of valuable insights and information. This knowledge, when properly documented and analysed, can significantly enhance future project performance and organisational knowledge.This applies also to profession.
