Organizational policies Capability maturity model integration ppt to Perform includes practices that establish the necessary conditions for implementing the process completely. Plans, resources, responsibility, and training.
Activities Performed includes practices that directly implement a process area. Directing Implementation includes measurement practices that are necessary to collect and analyze data related to the process. Configuration management, stakeholder involvement, monitor and control Verification includes practices that ensure compliance with the process that has been established.
Organizational Process Definition Establishes and maintains a usable set of organizational process assets. Organizational Training Develops the skills and knowledge of people so they can perform their roles effectively and efficiently. Plans - Questions - Metrics Org. Monitoring and Control - Experience Base Org.
Generate a set of organizational goals What do you want to improve? Derive a set of questions relating to the goals Answers provide visibility into meeting the goals Develop a set of metrics needed to answer the questions  Victor Basili, Software Modeling and Measurement: To characterize, evaluate, predict, motivate, etc. Examine the cost, effectiveness, correctness, defects, changes, product metrics, reliability, etc.
The environment consists of the following: Predict the process in order to manage it Improve software process predictability Project tracking goal area: Evaluate the process in order to improve it Improve the software process Improve quality Minimize schedule Improve productivity Maximize reuse Defect prevention goal area: Is productivity increasing over time?
How well are inspections performing? What is the return of inspections? What are high-leverage opportunities for defect prevention? What are optimal inspection parameters? Is the Capability maturity model integration ppt process under control?
How effective have process changes been?
Metric inspection efficiency defect removal effectiveness inspection ROI defect density trends productivity trends inspection rate control chart effectiveness vs. Improve effort predictability Question: How accurate are post-calibrated effort estimates Metric: Relative effort error distribution Goal: Is the effort estimation process under control?
How can we predict effort? What are the relative impacts of the scale factors? Characterize the process to understand it Question: Does the profile of tool usage differ between project subgroups? Frequency histogram of tool usage ratings Goal: How does defect density compare among project subgroups? How does productivity compare between project subgroups? Continuous frequency histogram of actual productivity per subgroup Goal: Characterize the process in order to understand it Question: How does the effort adjustment factor compare among projects?
Is defect density decreasing over time? Defect density trend chart of completed projects Goals: Adhere to cost and schedule budgets current project Questions: What are the cost and schedule variances? Defect category distributions Goal: Where is the cycle-time taken in the lifecycle phases?
Encapsulate our understanding of development processes and support organizational learning. Benchmark process improvement since models are calibrated to our process environment. Do measures distribute into a bell curve? What is the average? Do we meet specifications? In QPM, projects use quantitative techniques to take process measurements, analyze their software process, identify special causes of variations in the performance of the process, control the performance of the process within well-defined limits, and "Capability maturity model integration ppt" their results.
In SQM, projects take measurement and analyze product quality, identify special causes of variations, control the quality within well-defined limits, and report their results. Measurable goals for software product quality and their priorities are defined.
Actual progress toward achieving the quality goals for the software products is quantified and managed. Software process performance represents the actual results achieved following a software process. Group exists for coordinating QPM Ab1 4. Support for collecting, recording, and analyzing data Ab3 6.

Process goals productivities, defect densities, review effectiveness are calculated from combining indicator data. The organization has the means to identify weaknesses and strengthen the process proactively, with the goal of preventing the occurrence of defects. Data on the effectiveness of the software process is used to perform cost benefit analyses of new technologies and proposed changes to the organization's software process.
Innovations that exploit the best software engineering practices are identified and transferred throughout the organization. Software project teams in Level 5 organizations analyze defects to determine their causes. Software processes are evaluated to prevent known types of defects from recurring, and lessons learned are disseminated to other projects. Level "Capability maturity model integration ppt" organizations are continuously striving to improve the range of their process capability, thereby improving the process performance of their projects.
Improvement occurs both by incremental advancements in the existing process and by innovations using new technologies and methods. The purpose of Process Change Management PCM is to continually improve the software processes used in the organization with the intent of improving software quality, increasing productivity, and decreasing cycle time for product development.
Defect Prevention involves analyzing defects that were encountered in the past and taking specific actions to prevent the occurrence of those types of defects in the future. The defects may have been identified on other projects as well as in earlier stages or tasks of the current project. Defect prevention activities are also one mechanism for spreading lessons learned between projects. Trends are analyzed to track the types of defects that have been encountered and to identify defects that are likely to recur.
Based on an understanding of the project's defined software process and how it is implemented as described in the Integrated Software Management and Software Product Engineering key process areasthe root causes of the defects and the implications of the defects for future activities are determined. Both the project and the organization take specific actions to prevent recurrence of the defects. Policy for organization to perform DP activities C1 2. Policy for projects to perform DP activities C2 3.
Organization-level team exists to coordinate DP activities Ab1 4. Project level team exists to coordinate DP activities Ab2 5. Team has kick-off meeting to prepare for DP activities Ac2 3. Conduct causal analysis meetings Ac3 4. Conduct coordination meetings to review the implementation of action proposals from the causal analysis meetings Ac4 5. Document and track DP data Ac5 6. DP activities are planned G1 2. Common causes of defects are sought out and identified G2 3. Technology Change Management involves identifying, selecting, and evaluating new technologies, and incorporating effective technologies into the organization.
