3 CMMI SM 8/25/2014Bahill3 What is CMMI? The Capability Maturity Model Integration (CMMI) is a collection of best practices from leading engineering companies. It provides a model that you can base your company processes on.

4 CMMI SM 8/25/2014Bahill4 A system can be implemented with software hardware bioware algorithms organizations processes You can call these types of systems.

5 CMMI SM 8/25/2014Bahill5 What is process? A process is a set of practices performed to achieve a given purpose; it may include tools, methods, materials, and/or people.

6 CMMI SM 8/25/2014Bahill6 Why focus on process? Process provides a constructive, high-leverage focus... as opposed to a focus on people -Your work force is as good as it is trained to be. -Working harder is not the answer. -Working smarter, through process, is the answer. as opposed to a focus on technology -Technology applied without a suitable roadmap will not result in significant payoff. -Technology provides the most benefit in the context of an appropriate process roadmap.

7 CMMI SM 8/25/2014Bahill7 When creating a process the most important facets are illustrating tasks that can be done in parallel suggesting feedback loops including a process to improve the process configuration management

8 CMMI SM 8/25/2014Bahill8 Why use CMMI? CMMI provides guidance for improving your organization’s processes and your ability to manage the development, acquisition, and maintenance of products or services. CMMI places proven approaches into a structure that -helps your organization examine the effectiveness of your processes -establishes priorities for improvement -helps you implement these improvements

9 CMMI SM 8/25/2014Bahill LTI Process Capability. A multidisciplinary, structured, and integrated development process with a strong emphasis on systems engineering, software engineering and integrated product and process development (IPPD) will be a cornerstone of the program. Capability Maturity Model Integration, Version 1.1, will be used as a guideline and benchmark when evaluating offeror’s systems engineering, software engineering and IPPD maturity and capabilities. Certification by relevant Capability Maturity Models (e.g., SECAM, SE-CMM, IPDCMM, etc.) is not required, except for Software Engineering, however, if such certifications have been obtained, that certification information will be considered during the Government’s evaluation process. … The LTI shall implement software management processes maintained at no less than level 3 of the Capability Maturity Model for Software (SW-CMM).

11 CMMI SM 8/25/2014Bahill11 CMM Integration SM Project The CMM Integration Project was formed to build an initial set of integrated models establish a framework to enable integration of future models create an associated set of appraisal and training products Source models serving as the starting point for CMMI were SW-CMM (software), V2.0 Draft C EIA 632 (engineering) EIA/IS-731 (systems engineering) IPD-CMM (integrated product development), V0.98

12 CMMI SM 8/25/2014Bahill12 CMMI development team Membership from industry U.S. government Software Engineering Institute Membership characteristics average of about 21 years experience from organizations with solid process improvement credentials Financing from DoD

13 CMMI SM 8/25/2014Bahill13 Development strategy Base the model content on current industry best practices as represented in widely- accepted source models. Conduct public reviews of the models. Conduct pilots of the product suite prior to official product release. Update the product suite based on feedback from pilots and reviewers. Release v1.0 of the product suite. Update the product suite based on feedback from users. Release v1.1 of the updated product suite.

14 CMMI SM 8/25/2014Bahill14 The Bottom Line Process improvement should be done to help the business— not for its own sake. “In God we trust, all others bring data.” - W. Edwards Deming

15 CMMI SM 8/25/2014Bahill15 Categories of benefits Process improvement benefits fall into these general categories: improved schedule and budget predictability improved cycle time increased productivity increased customer satisfaction improved employee morale increased return on investment improved quality (as measured by defects) decreased cost of quality

19 CMMI SM 8/25/2014Bahill19 Measurable return on investment Return on software improvement investment was reported to be between 5:1 and 8:1. (Herbsleb 94) Process improvement provides measurable return on investment.

20 CMMI SM 8/25/2014Bahill20 Improved program performance Performance to contract Cost at Completion = Budget Increases in productivity 150% over 5 years Industry Cost / Schedule Estimation Tool (COCOMO) projects 20% reduction in effort for 1 level improvement Decreases in Cost of Nonconformance 40% down to 10% Increased customer satisfaction ROI 5:1 and greater Raytheon Missile Systems Software Center

21 CMMI SM 8/25/2014Bahill21 Remember The CMMI model is not a process. This model shows what to do, Not how to do it or who does it.

22 CMMI SM 8/25/2014Bahill22 The IDEAL SM Model SM IDEAL is a service mark of Carnegie Mellon University. The IDEAL model maps to the SIMILAR Process

23 CMMI SM 8/25/2014Bahill23 Using CMMI models with the IDEAL model 1 Initiating phase CMMI models can assist an organization in understanding how to build sponsorship and in developing the infrastructure for improvement. Diagnosing phase The Standard CMMI Appraisal Methodology for Process Improvement (SCAMPI SM ) provides a yardstick for appraising processes based on CMMI. SM SCAMPI is a service mark of Carnegie Mellon University.

24 CMMI SM 8/25/2014Bahill24 Using CMMI models with the IDEAL model 2 Establishing phase CMMI process areas focus the process improvement teams. Acting phase CMMI models provide guidance for defining or improving processes. Learning phase Lessons learned are documented and are the basis for revision of an organizational approach.

25 CMMI SM 8/25/2014Bahill25 Process notation schemes 1 Process notations should represent What activities are performed in the process? Who does them? Why are they done? When are they done? How are they done? What inputs must you have? What outputs do you produce? How do you measure performance?

26 CMMI SM 8/25/2014Bahill26 Process notation schemes 2 Different notation schemes emphasize different aspects of a process and, thus, have different strengths and weaknesses. Different notations may or may not have the ability to conveniently represent sequencing of activities timing of activities data flow among activities hierarchical detail entry and exit criteria narrative information

27 CMMI SM 8/25/2014Bahill27 Process notation schemes 3 Other notation scheme attributes flexibility simplicity ease of training and understanding availability of tool support

48 CMMI SM 8/25/2014Bahill48 Generic Goals (GG) Achievement of a generic goal in a process area signifies improved control in planning and implementing the processes associated with that process area. Generic goals are called “generic” because the same goal statement appears in multiple process areas. Each process area has only one generic goal at each level.

49 CMMI SM 8/25/2014Bahill49 Level 2 generic goal The generic goal for all maturity level 2 process areas is: GG 2: The xxx process is institutionalized as a managed process. A managed process is a performed process that is planned and executed in accordance with policy; employs skilled people having adequate resources to produce controlled outputs; involves relevant stakeholders; is monitored, controlled, and reviewed; and is evaluated for adherence to its process description.

50 CMMI SM 8/25/2014Bahill50 Generic Practices (GP) Generic practices are activities that ensure that the processes associated with the process area will be effective, repeatable, and lasting. Generic practices contribute to the achievement of the generic goal when applied to a particular process area.
