Understanding and defining the assessments with TiSH
Maturity models are one instrument to plan or influence transformation, by determining where we stand today and where we want to go. The most well-known maturity model is the Capability Maturity Model (CMM), which basically defines at what level organizations have matured in software development. However, CMM is used more widely than just in software development, and frankly, the principles of CMM are quite commonly used in other terrains as well.
As you can see in the following diagram, the TiSH staircase has been inspired by it.
Figure 10.1 – The five levels of the CMM
The basic level of the maturity model is Initial. At this level, processes are not well defined. Outcomes are unpredictable since processes are poorly controlled and highly reactive. The next level in CMM is Managed. In CMM, it means that processes are defined per project but still very reactive. Even worse, since they are defined...
