Generalize the maturity model pattern (#536)

Main Change: Generalize the Solution section. Separate the definition of the maturity model from the self-assessment of the teams. Emphasize that an org that adopts this pattern should review the maturity model and adapt it to their needs, before asking teams to do the self-assessment.

Minor changes:
* Formatting Forces, Context and Resulting Context as lists, to allow for easier checking
* Rewrite Patlet into the 2 sentence form (1 problem + 1 solution)
* Adding new Patlet for pattern Maturity Model to the README

+## Solution
 
-Teams are not aware of best practices that would help them solve issues that
-they run into in their daily doing.
+For this pattern it is particularly important that you adapt the maturity model below to the needs of your organization.
+The context of most organizations will differ too greatly, so there is no single maturity model that fits every org.
 
-## Solution
+Steps to implement:
+
+1. **maturity model definition**: Create a maturity model that fits the needs of your organization. Also consider the [Guiding Principles](../2-structured/document-your-guiding-principles.md) if you have defined those for your InnerSource program.
+2. **team self-assessment**: Then ask teams to self-assess against that maturity model. You may even do a couple of these sessions together with a few teams, to observe and learn if the maturity model is easy enough to understand.
+3. Define a maturity goal post assessment, derive tasks, add to your backlog, and schedule with your preferred planning system. Reassess after some time. e.g. yearly review
+
+The process of going through these steps helps your organization in multiple ways:
 
-Ask teams to self assess against the proposed maturity model.
+* Defining your own maturity model allows you, the organizers of the InnerSource program, to increase your own clarity. e.g. you will realize what matters to you, what training capabilities you have internally, what material is available externally, etc
+* You increase the trust in your initiative by allowing teams to go through the self-assessment at their own pace, and by opening up to feedback from them.
+* The teams going through the self-assessment will likely have discussions, possibly even disagreements about some of the points in the maturity model. These are fantastic conversation starters, and the discussions help you to create a shared understanding of InnerSource in your organization.
+
+Below we have defined a **sample maturity model** around 4 categories: Transparency, Collaboration, Community, and Governance.
+
+And again: Make sure you adapt this model to fit your organization before applying it!
