Software Process Assessment

9/19/2014Software Process AssessmentA method of determining the effectiveness of the software process with agoal towards improving the process.Software Process Assessment Approaches– Capability Maturity Model Integration (CMMI)– Standard CMMI Assessment Method for ProcessImprovement (SCAMPI)– CMM-Based Appraisal for Internal ProcessImprovement (CBA IPI)– SPICE (ISO/IEC 15504)– ISO IEC 90003:2004 Software EngineeringStandard1

9/19/2014CMMI provides organizations with the essentialelements of effective processes, which willimprove their performance. includes identifying your organization’sprocess strengths and weaknesses and makingprocess changes to turn weaknesses intostrengths.CMMI Models The CMMI for Acquisition (CMMI-ACQ) model. The CMMI for Development, (CMMI-DEV)model is used for process improvement inorganizations that develop products andservices. CMMI-DEV provides guidance toimprove the effectiveness, efficiency, andquality of their product and servicedevelopment work. The CMMI for Services (CMMI-SVC) mode.2

9/19/2014SCAMPI Standard CMMI Assessment Method forProcess Improvement It is designed to provide benchmark qualityratings relative to the CMMI. Used for both internal process improvementand external capability determinations. eports/06hb002.cfmCBA IPI CMM-Based Appraisal for Internal ProcessImprovement A diagnostic tool that supports, enables, andencourages and organization’s commitment toprocess improvement. It helps to identify a company’s strengths andweaknesses of its current processes withregards to the CMM.6
