Many waste great opportunities to gather very valuable information by taking projects that went well for granted. A typical saying is “The project went well, why bother talking about it?”, which is important to prevent, otherwise you may waste precious lessons you can apply elsewhere.
Projects that went well means that events/actions/etc. occurred which made it go well. So what exactly helped here? Identify all the positive elements of the project and make sure you get to the root of that positivity. By that, I mean, avoid being vague like “we had a great team working on this”. The root of this might be that the team has worked a lot together in the past and communicate greatly.
Once all this is gathered, figure out what can be applied to other projects, and make sure it’s actionnable.
For example, if a project went well because the client supplied everything on time, and you identify that the client was reminded weekly, with a simple list of what to deliver and when, then how about applying this technique with other clients?
Have a lessons learned meeting even for positive projects; they are just as important as any other lessons learned mettings where you can make sure to learn from the project.
