WM Software Process & Quality SPiCE Requirements - slide#1 1  Paul Sorenson REQUIREMENTS FOR A SPiCE ASSESSMENT A set of defined input information has to be prepared before the assessment. Assessment has to be against a model that is SPICE reference model. compatible with the SPICE reference model. The model has to provide indicators to guide the assessor in rating the processes of the reference model. process ratings The assessment results, the process ratings, have to be justified objective evidence of the existence of the indicators in the assessment model.

Generally there are process performance indicators and process management indicators. + Objective evidence - based on the indicators, must be documented to justify assessment ratings + Example indicators - work products, practices, records, reports.
