Process Improvement Frame Work

There are different frame works such as:

ISO 9001

SEI CMMI

IEEE

TQM

Why?-SEI CMMIqCMMI is more tightly connected with the

SDLC

qIts delivery in the form of multiple levelscreates an environment of gradual climbing

of a ladder in the quality maturity level

Process Improvement Strategy

Study an existing process to understand itsactivities.

Produce an abstract model of the process.

Analyse the model to discover process

problems. This involves discussingprocess activities with stakeholders anddiscovering problems and possibleprocess changes.

Process Improvement Model Set the Goal

Constitute the Software EngineeringProcess Group (SEPG)

Flow Chart the current Processes

Organize the process champions

Simplify the process and makechanges

Get feedback from practitioner

Remove bottlenecks and weakprocesses after review

Baseline the process

Train the practitioners

Process Implementation - activity

Senior Management - committed and provided

all necessary resources. SEPG - Responsible for ensuring the process

improvement activities addressing CMMI

Framework Process Champions-Refining and documenting

the processes

Practitioners Collective knowledge, experiencesand efforts were utilized as a powerful tool toimproving the processes

Process Implementation - Execution

Developing the documentation of QMS, this includes

quality manual, processes, working instructions,forms, templates, and checklists and base lining.

Practical training of CMMI implementation to endusers.

Conducting the periodical audit to help User todiscover the potential issues of QMS.

Building the QMS web site where all the process,

templates, checklist, tools, methods of best practiceand training materials are shared throughout theorganization.

Process Implementation - ExecutionCont.

Adaptation of tools VSS/CVS, to performconfiguration management, and MS Project2003 to perform project management.

Building up quantitative management

mechanism to analyze the quality trend andrevise the reasonable quality expectation.

Conducting regular (at least monthly) process

focused meetings with all key process areamembers to ensure steady progress.

Software Testing

Process quality and product quality areclosely related and processimprovement benefits arise because thequality of the product.

Testing difficulties in R & D

Shorter time to complete the testing Design and functionality of product features

changes often

New features that are added or deleted,depending upon the progress of the project.

but - No change in timeframe

Testing Strategy Evolved

Beginning the test planning earlier in thedevelopment life cycle

Understanding the Project and map the

requirements with test cases Leveraging the results of previous test efforts

Improving the management of resources

Standardization of the test cases Reusing existing Test Cases from repository

Quality Improvement Both product and process assessment are required

for quality improvement. How? Performing Testing activities, conducting audits

and SQA assessments help to improve the

process throughout the organization Review of all the processes and documents are

done rigorously by the audit team so that

margin of error is very less. Project Leaders were helped to close the Non

Compliance of quality standards and improvethe process compliance.

Lesson Learnt Keep sizable goals

Clear understanding for targets and percolate it down Everyone needs to be engaged train the masses

Utilize Teams as process champions

Multi-department representation Start the implementation with the groups that want to

improve, which eager to benefit from efforts andare able to recognize their own weaknesses

Provide skilled coaching, resources, support, and tools Publicize successes; Share best practices

Conclusion

Processes enable people to develop their potential

more fully and are more effective within theorganization.

By defining, measuring, and controlling the process,improvements are more successful and sustained.

Appropriate technology, techniques, and tools areintroduced successfully increases predictability.

The planning and estimation of project scope,

schedule, resource and cost are clearer and bettercontrolled based on the quantitative management
