ISO 15504 (SPICE)

-- Why another standard/model?
"Destiny is not a matter of chance, it is a matter of choice: 
it is not a thing to be waited for, 
it is a thing to be achieved." 
-- William Jennings Bryan 
The ISO 15504 (SPICE) model is still considered in its infancy--the ISO 15504 model was released as a technical report in 1998--it is not yet released as an official standard.

Many people are asking questions--the key question being "why another standard/model?"

One of the primary benefits that ISO 15504 provides is the ability to compare apples against apples.  As a customer, you will be able to judge "an organization assessed under the SEI SW-CMM model against an organization assessed under, say, the Trillium or Bootstrap model".  In view of the software vendor, you need not change your software process improvement model of choice (e.g., SEI SW-CMM, Trillium, Bootstrap,...) nor do you need to re-educate your Software Engineering Process Group on any new assessment framework.

Sound too good to be true?  Well, this is how ISO 15504 permits this to occur:
 
Bullet ! ISO 15504 has 2 standards:
-- ISO 15504-2 is a common base for different software process improvement models
-- ISO 15504-3 is the minimum requirements for performing assessments
Bullet ! Existing software process improvement models (like SEI SW-CMM, Trillium,...) need only be cross-referenced with ISO 15504-2 -- note: SEI has already released a high-level cross-reference
Bullet ! Existing assessment frameworks (like SEI CBA-IPI, SEI SCE, or a consultant's own assessment framework) need only be cross-referenced with ISO 15504-3.  Note, the FAA has already cross-referenced their FAA-iCMM® Appraisal Method.
Bullet ! Having cross-referenced your assessment framework and software process improvement model of choice, comparing apples against apples is then possible!

Now, that is worth another standard/model.  Do you not agree?
