What does "Organization being Appraised" mean in the SEI Maturity Reports?

I’m a big follower of SEI’s Maturity Reports, but I'm confused about the phrase "Based on the total number of employees within the area of the organization that was appraised”. Does this refer to the Organization Unit, or the Organization within which the Organizational Unit operates?

The concept of "Organizational Unit" exists within the Standard CMMI Appraisal Method for Process Improvement or "SCAMPI," the appraisal methodology used to appraise an organization. The "OU" represents the organizational scope of the appraisal itself, not the entire organization.

An OU could be a geographical location ("everyone in Toledo"), a functional organization ("Software development"), a management tree ("everyone reporting to Bill") or some other segmentation.

The OU must be credible and verifiable by the Lead Appraiser. So something like "every project with less than two people" with only one project in the scope would NOT be credible! Don't laugh, there is a famous example of one company, outside of NA, that did this.

Appraisals are conducted against the "OU", so it is technically only the "OU" that is awarded a maturity or capability level, and hence is the foundation of the data that is published by the SEI.

So therefore, the data in the report comes out of the SCAMPI results, which report the size of the OU, not the overall oganization.

How much of our company has to be ML 2 for us to say the whole company is ML 2?

Can you tell me what percent of your company needs to be recognized as certified Level 2 in order to state that your entire company is Level 2?



Contrary to popular belief, an entire company rarely achieves CMMI ML2 (or any other level for that matter). There is a concept in the SCAMPI Appraisal Method called an "organizational unit" that defines the target organization within a company that is to be appraised. When the appraisal is complete, you may say that your company has reached ML2, but in reality perhaps only a single organization in your company has reached that goal. That information is displayed on the SEI's appraisal results page, although I would argue that most people aren't aware of the concept when they look at.

The definition of the Organization Unit, or OU in Lead Appraiser speak, is something you discuss, and agree upon, with your Lead Appraiser. It needs to be credible (such as an entire location (Dayton, OH), a product line (mainframe payroll systems), a type of technology (all web development), or a management tree (everyone reporting to the Director of Engineering. . .). Inside of your OU, you and the Lead Appraiser will select a group of projects (3 or more) that is a representative sampling of the OU. Again, this is something you and LA agree on in advance.

A poor example is one where the OU is "all projects with the charge code 145387.

When it's all over (and if you're successful) if you're like most companies you will say [company name] is CMMI ML2. Some are more specific, and name the OU, but it my experience, most do not (right or wrong).

When you enter Baltimore-Washington airport there is a huge banner across the road that says "Lockheed-Martin - CMMI Level Five." I can assure you that, while they have achieved ML5 within some organizations, the "entire company" has not.

One exception I can think of is a company whose sole business is writing software in a single location. Perhaps then the company is ML5.

So, there are two ways to slice it. First, the organizational unit is agreed upon, and then a set of representative projects is selected. Make sense?
