In this chapter, you will find explanations about each individual concept used inside KE-chain, as well as description of each individual action you can perform (as a project manager) inside KE-chain. This means that, if you follow the manuals in the order they are meant to, you will be able to understand how a project lifecycle works, from the creation of the users that will work on it, until the project closure. You can find a schematic of such a project lifecycle in the right image.
