CMMI (Capability Maturity Model Integration) provides a framework for improving processes in organizations. It includes two types of levels - maturity levels and capability levels - to measure process improvement. There are two representations, staged and continuous, that allow organizations to measure improvement across predefined process areas or within individual process areas. Implementing CMMI best practices has proven benefits like improved schedule and budget predictability, increased productivity and quality, and reduced costs.

2. Outline Introduction CMMI Two Types of Leveling Maturity Levels Capability Levels Representations Staged Representation Continuous Representation Benefits & Improvements Conclusion

3. Introduction Thanks to globalization, projects are more distributed today. Products getting more complex because of the developing technology. Today’s competitive market forces companies to produce Faster Better Cheaper Companies have to manage complex product development and maintenence.

4. Intoduction Contd’ Some products developed requires both inhouse development and outsorcing. (Integration problem) Far out companies recognized that, they have to develop softwares in order to compete in the market. For example; Aerospace companies Car manifacturers Banks Those companies have to find a solution in order to manage that complex, generally integrated approach while developing products.

5. CMMI Organized collections of best practices Based on work (TQM) by Crosby, Juran, Deming, Humphrey… Systematic ordered approach to process improvement. Means of measuring organizational maturity. This model shows what to do, NOT how to do it or who does it Have proven to bring significant return on investment in productivity and quality .

6. CMMI Contd’ NDIA (National Defence Industrial Association), DoD (Department of Defence) are sponsored and collaborative work of SEI (Software Engineering Institute ), NDIA Systems Engineering Community and Government. I mprovement in any discipline , is a function of performing: Implementing practices that reflect the fundamentals of a particular topic ( For example: configuration management ) Institutionalizing practices that lead to sustainment and improvement of an implementation

7. Two Types of Leveling Maturity Level; A maturity level is a well-defined evolutionary framework in order to achieve a mature software lifecycle process . Capability Level; A capability level is a well-defined evolutionary stage describing the organization’s capability relative to a process area

8. Maturity Levels

9. Maturity Levels Contd’ Organizations or compaines which are maturity level 1(CMMI Level 1) have poor managed processes and generally exceed the schedule and budget constraints. Highest level (CMMI Level 5) compaines have achieved the defined goals of the process aresas covered by lower levels.

10. Capability Levels

11. CMMI Levels Mainly Coverage

12. Two Types of Representations Organizational maturity is the focus of the staged representation, whereas process area capability is the focus of the continuous representation.

13. Difference Between Represantations Staged Process improvement is measured using maturity levels Maturity level is the degree of process improvement across a predefined set of process area s Organizational maturity pertains to the “maturity” of a set of processes across an Organization Continuous Process improvement is measured using capability levels Capability level is the achievement of process improvement within an individual process area Process area capability pertains to the “maturity” of a particular process across an organization

14. Advantages of each representation Staged Provides a roadmap for implementing groups of process areas sequencing of implementation Continuous Provides maximum flexibility for focusing on specific process areas according to business goals and objectives

15. Benefits & Improvements Benefits of process improvements Improved schedule and budget predictability Improved cycle time Increased productivity Improved quality (as measured by defects) Increased customer satisfaction Improved employee morale Increased return on investment Decreased cost of quality

20. Benefits SEI Software CMM Level 5: For the Right Reasons* Defects are now nearly all found and fixed before testing begins. Defects escaping into the field have been reduced from 11% to practically 0%. Programs consistently reach customer satisfaction and performance targets. Peer reviews increase total project costs by 4%, but reduced rework during testing by 31%. R.O.I. is 7.75:1. Applying CMMI may not be fully beneficial for a small scaled organization having a few resources *Reference: Yamamura and Wigle, Boeing Space and Transportation Systems, Crosstalk , Aug, 1997.

21. Benefits Contd’ The SEI published that 60 organizations measured increases of performance in the categories of cost, schedule, productivity, quality and customer satisfaction. These results do not guarantee that applying CMMI will increase performance in every organization Documented Benefits (median improvement ) 30 o rganizations Cost - 34% Schedule - 50% Productivity – 61% Quality – 48% Customer Satisfaction -14%

22. Conclusion CMMI provides Efficient, effective assessment and improvement across multiple process disciplines in an organization Improvements to best practices incorporated from the Software CMM A common, integrated vision of improvement for all elements of an organization A means of representing new discipline-specific information in a standard, proven process-improvement context
