Trainings on different Requirements Elicitation Techniques, so that there are minimal Change Requests from the client and less effort is spent on rework.
Training on Estimation Techniques, so that Effort can be best estimated for Development and Non-Development Effort.
Training on Best Coding Practices was identified and provided to the team.
Productivity target and defects rate at Individual Programmers Level was made aware to them so that they have their targets for productivity and defect injection.
Regular monitoring of these targets was done. Productivity log and Defect injection log were maintained for every programmer.

Following benefits were observed by the organization:
Quantitative Benefits: 15-20% improvement in Productivity was achieved as a result of reduced Rework Effort in the projects.
