Based on recent project performance, where would you pin down your Capability Maturity level?

Saying you are capable and mature
is not the same as being capable and mature!

Take a look at the bottom of the ladder on the image above!
Can you see that following process is how you climb up the Capability Maturity ladder?
If you think that Agile does not follow process (a typical Capability Maturity Level 1 perception) you are seriously uninformed.
Open Scrum here
to see this agile method's processes. Did you see that Scrum has the core processes PP and PMC?  Now see if you can tie the CML2 processes PP and PMC back to the PMBOK dashboard.
Note: each link above opens in a new tab so you can "cross compare" results.

Now take a good look at the Program Termination Zone on the image above.  
Remember that a Program is simply a bunch of strategically aligned projects.

For Systems Engineering the CMMi Dashboard for Development is your playbook!
This is one of 4 process improvement dashboards used by the Carnegie Mellon University in their Capability Maturity Model integrated body of knowledge.
See if you can connect the Capability Maturity Level 2 processes on the CMMi Dev. Dashboard (look for 'ML' on the dashboard) to the PMBOK Process Dashboard and Agile's Scrum Process Dashboard.   The 4 CMMi dashboards combine and use most of these processes, while some have specialist processes dedicated only to them.

The above information, in a 'nutshell' is the absolute essence of being able to operate at Capability Maturity Level 2!
