  • 1. Introduction to CMMI By Ms. Kiran Khot CMC Limited
  • 2. What is SEI CMMI• SEI CMMI is the successor of SEI CMM• CMM describes about the software engineering alone where as CMM Integrated describes both software and system engineering.• CMMI evolved as a more matured set of guidelines and was built combining the best components of individual disciplines of CMM (Software CMM, People CMM etc).• The goal of the CMMI project is to improve usability of maturity models for software engineering and other disciplines, by integrating many different models into one framework.• There are 3 constellations of CMMI in the new version: CMMI Development (Software Engineering and System Engineering), CMMI Services (Operations and Support) and CMMI Acquisition.• CMMI Model is not a process, it describes the characteristics of effective processes. 6th July 2007 Introduction to CMMI, CMC Ltd 2
  • 3. Benefits of CMMI Implementing a disciplined process in an organization helps in achieving:• Improvement in organization’s control over execution of projects• Increase the ability to meet project goals and improve profitability• Improvement in productivity, quality, decrease in project cycle time• Improvement in customer satisfaction, meeting business objectives• Improvement in business and growth The return is also indicated as decrease in Cost of Quality and decrease in Cost of Poor Quality (COPQ). 6th July 2007 Introduction to CMMI, CMC Ltd 3
  • 4. Representations in CMMIThere are two types of representations in CMMI• Staged• Continuous 6th July 2007 Introduction to CMMI, CMC Ltd 4
  • 5. Staged Representation• It is an approach used in CMM – Software• It uses predefined sets of process areas to define an improvement path for an organization• This improvement path is described by a model component called maturity level• A maturity level is well defined evolutionary plateau towards achieving improved organization processes• Maturity levels, apply to an organization’s process improvement achievement across multiple process areas• There are five maturity levels, numbered 1 through 5 6th July 2007 Introduction to CMMI, CMC Ltd 5
  • 6. Staged Representation Maturity LevelsProcess Area 1 Process Area 2 Process Area 3 Specific Generic Goals Goals Specific Generic Practices Practices 6th July 2007 Introduction to CMMI, CMC Ltd 6
  • 7. Continuous Representation• It uses capability levels to characterize improvement relative to an individual process area• This approach allows an organization to select a specific process area and improve relative to it• Capability levels, apply to an organization’s process improvement achievement in individual process area• These levels are means for incrementally improving the processes corresponding to a given process area• There are six capability levels, numbered 0 through 5 6th July 2007 Introduction to CMMI, CMC Ltd 7
  • 8. Continuous RepresentationProcess Area 1 Process Area 2 Process Area 3 Specific Generic Goals Goals Specific Generic Practices Practices Capability levels 6th July 2007 Introduction to CMMI, CMC Ltd 8
  • 9. Components Associated with Representations Process Area: A process area is a cluster of related practices in an area that, when implemented collectively, satisfies a set of goals considered important for making significant improvement in that area. Specific Goals: A specific goal describes the unique characteristics that must be present to satisfy the process area. Specific Practices: The activities expected to result in achievement of specific goals. 6th July 2007 Introduction to CMMI, CMC Ltd 9
  • 10. Components Associated with Representations Generic Goals: A generic goal describes the characteristics that must be present to institutionalize the processes that implement a process area. They are termed “generic”, because the same goal statement appears in multiple process areas. There are 5 generic goals Generic Practices: The activities expected to result in achievement of generic goals. 6th July 2007 Introduction to CMMI, CMC Ltd 10
  • 11. Generic Goals and Practices Goal 1: Achieve Specific Goals: Practices: Perform base practices to develop work products and provide services to achieve the specific goals of the process area. Goal 2: Institutionalize a Managed Process: Practices:• Establish an organization policy• Plan the process• Provide Resources• Assign Responsibility• Train People• Manage Configurations• Identify and involve relevant stake holders• Monitor and control the process• Objectively evaluate adherence• Review status with high level management 6th July 2007 Introduction to CMMI, CMC Ltd 11
  • 12. Generic Goals and Practices Goal 3: Institutionalize a Defined Process: Practices:• Establish a defined process• Collect improvement information Goal 4: Institutionalize a Quantitatively managed Process: Practices:• Establish quantitative objectives for the process• Stabilize sub process performance Goal 5: Institutionalize an Optimizing Process: Practices:• Ensure continuous process improvement• Correct Root Cause of Problems 6th July 2007 Introduction to CMMI, CMC Ltd 12
  • 13. Capability Levels Capability 0: Incomplete:• An incomplete process is a process that is either partially performed or not performed at all.• One or more SG of the PA are not satisfied• No GG exist for this level Capability 1: Performed:• A performed process satisfies the SG of the respective PA.• Supports some GG (typically the work needed to produce work products) Capability 2: Managed:• A managed process has a basic infrastructure in place to support the process• It is planned and executed in accordance with policy• Employs people who have adequate resources to produce controlled outputs• Is monitored, controlled, reviewed and evaluated for adherence to its process description 6th July 2007 Introduction to CMMI, CMC Ltd 13
  • 14. Capability Levels Capability 3: Defined:• A defined process is a managed process that is tailored from the organization’s set of standard processes according to the tailoring guidelines• Contributes work products, measures, and other process improvement information to the organizational process assets Capability 4: Quantitatively Managed:• A quantitatively managed uses statistical and quantitative techniques• Quantitative objectives for quality and process performance are established Capability 5: Optimizing:• An optimizing process is quantitatively managed process that is improved based on an understanding of the common causes of variation in the process• The focus is on continually improving the range of process performance through both incremental and innovative improvements 6th July 2007 Introduction to CMMI, CMC Ltd 14
  • 15. Maturity Levels Maturity 1: Initial:• Processes are usually ad hoc and chaotic• No stable environment in the organization to support the processes• Success depends on competence and heroics of the people in the organization and not on the use of processes• Frequently, schedules are not met and projects exceed budgets Maturity 2: Managed:• Processes have ensured that requirements are managed and that processes are planned, performed, measured and controlled• Ensures that existing practices are retained during times of stress• Work products and delivery of services are visible to management at defined points• Work products are appropriately controlled Maturity 3: Defined:• Processes are well characterized and understood and are described in standards, procedures, tools and methods• Processes are used to establish consistency across the organization 6th July 2007 Introduction to CMMI, CMC Ltd 15
  • 16. Maturity Levels Maturity 4: Quantitatively Managed:• Organization and projects establish quantitative objectives for quality and process• Special causes of variation are identified and appropriately are corrected to prevent future occurrences• Quality and process performance measures are incorporated into the organization’s measurement repository to support fact based decision making Maturity 5: Optimizing:• Organization continuously improves its processes, based on quantitative understanding of common causes of variation inherent in the processes• Both the defined processes and organization’s set of standard processes are targets of measurable improvement activities 6th July 2007 Introduction to CMMI, CMC Ltd 16
