- The Process DataBase contains data for each project.
- PCB Represents the capability of the process at some point in time in quantitative terms.
- Capability of a process: - The range of output did can be expected from a project, When the process is Carried out.
- Capability of stable process: - Can Be Determined from past performance of the process.
- Baselines: - If They are Regularly established, trends in the process capability can be Easily Obtained.
- First issue: - What should be added to PCB; IE., What type of outcomes Should the PCB include.
- Example Process Capability Baseline at Infosys: - Involves the Following ..1) Delivered quality.2) Productivity.3) Schedule.4) Effort distribution.5) Defect injection rate.6) In process defect removal efficiency.
7) Cost of Quality.
8) Defect distribution.
- The data in PCB can be used for project planning.
- PCB serves as one important role in overall process management in the organization.
- Since you can Easily measure process improvements by analyzing the trends in the PCB overtime.
- We must create a separate line for each process in the base organization.
- EC., At Infosys separate processes are defined for maintenance, re-engineering and development projects.
- If projects of a Certain type are Executed frequently, a PCB is created for that project.
- Focused baseline: - Gives much closer range in terms of expected values for that type of project.
- Interpretation of PCB is straightforward.
- PCB for development projects: - * the average productivity is about 12 function points per person month, with the range being from 4 to 31 function points. * The average quality is 00:02 defects per function point, with the range being 0:00 and 0.094. * THEREFORE gives range for defect injection rate and total defect removal efficiency.
- Cost of Quality: - includes cost of all activities did prevent or remove defects.
- For effort, defect and defect injection rates it THEREFORE specifies a distribution among the various stages.
