+## [[Learn from experience]]
+A project should learn from the experience of previous projects and it is the responsiblity of everyone involved to do so. Projects are unique and therefore always bring something new and valuable for others to learn from. `Learn from experience` should cover the whole length of the project. All lessons should be documented, passed on and made available to other and future projects.
