Improving quality of software development through CMM implementation
 
 
The idea
Improve the quality of the entire software development process and ensure CMM Level 2 process quality for all key process areas (KPAs).
 
The client

A leading telecom products company

 
The business challenge

There was a high degree of requirements volatility with ever-changing requirements. The existing requirements management practice was not robust enough to handle this. There was an absence of formal estimation processes with a lack of proper documentation and no rationale for estimates. This resulted in incorrect estimations and a change of project plans during the course of the project.

There was a high degree of post release defects handled by the support team which was not being fed back to the development team. The review process was also not adequate enough to analyze the review data captured. Any process addition or process improvement initiative was looked upon as a cost to the product lifecycle. The organization culture focused on defect management rather than defect prevention.

 
The solution
An initial mini assessment was done to analyze the gaps in the existing system. Process action teams were then formed to address these gaps. The process action teams, under the guidance of the Wipro consultant, looked at individual KPAs and tried to address the gaps in the same. The requirement management measures and change management process were defined for the key projects. In project planning, new project management roles were defined.

A methodology for tracking effort was laid down and a tool was created and implemented to track efforts. A new estimation methodology was also drafted. Quality planning was also implemented along with core project metrics which were then regularly reviewed. A new approach to configuration management procedure was proposed along with necessary templates. Change management metrics were defined and software configuration management planning, change control, status accounting and configuration audits were implemented.

The Wipro consultant provided the necessary training and mentoring to the process action team members as well as the practitioners.
