Maturity Levels Improvement institutionalized Continuously improving process Quantitatively Managed (4) Predictable process Defined (3) Standard, consistent process Managed (2) Disciplined process Initial (1) Optimizing (5) Quantitative control Technical practices are integrated with management practices and institutionalized Project Management practices are institutionalized Process in informal and adhoc © Software Engineering Institute © Confidential 3 www. qminds. co. in

The Initial Level (1) Environment not stable for developing and maintaining systems Inadequate management and engineering practices Ineffective planning Reaction-driven commitment systems Emphasis on development and testing during crisis Success depends on having exceptional people Unpredictable process capability Unpredictable schedules, budgets, functionality, and quality Few stable processes Process Capability can be summarized as Adhoc © Confidential 4 www. qminds. co. in

The Managed Level (2) Policies for managing projects Planning and managing based on experience Allows repeatability of successful practices Specific processes implemented by the projects may differ Realistic project commitments Costs, schedules and functionality tracked Requirements and work products are base lined Standards defined and conformed to Strong customer-supplier relationship with subcontractors A measurement process is in place Process Capability can be summarized as Disciplined © Confidential 5 www. qminds. co. in

The Defined Level (3) Organization-wide standard processes Effective engineering practices Integration of engineering and management processes Reuse of organizational learning Process Engineering Group (PEG) Organization-wide training program Project’s “Defined Process” Good management insight into the technical progress on all projects Process Capability can be summarized as Standard and Consistent © Confidential 6 www. qminds. co. in

The Quantitatively Managed Level (4) Quantitative goals for projects and processes Variation in process performance narrowed Meaningful variations can be distinguished from random variation Products are of high quality Projects are controlled quantitatively Process can be summarized as Predictable © Confidential 7 www. qminds. co. in

The Optimizing Level (5) Organization focused on process improvement incremental advances in existing processes innovations using new technologies and methods Proactive identification of weaknesses to strengthen processes Goal of preventing occurrence of defects through error-cause removal Cost-Benefit analyses of introducing new technologies and proposed process changes Process Capability can be summarized as Continuously Improving CMMISM Development v 1. 3 M 03 -Staged.
