SP 2.1 Implement the selected action proposals that were developed in causal
analysis.
SP 2.2 Evaluate the effect of changes on process performance.
SP 2.3 Record causal analysis and resolution data for use across the project
and organization.
As we discussed in Chapter 8, ???Understanding Maturity Level 5??”Optimizing,???
you can be doing these CAR activities much sooner than Level 5. However,
from a high-maturity perspective, these activities become mandatory for a useful
Level 5 implementation and very desirable for a successful Level 4.
When transitioning to Level 4, use the steps described as part of CAR to investigate
special causes of variation for their root cause. As stated previously, it is best
to get project team members involved with this analysis, since the recorded data are
likely to be incomplete. Put corrective actions in place across the organization to
address the root causes, as appropriate.
At Level 5, use the steps in CAR when looking for incremental improvements.
These steps can be the basis to investigate common causes of variation in your standard
processes and technology usage, and to establish a plan to remove some of the
undesirable common causes.
