  1. PROJECT DATABASE(PDB) & PROCESS CAPABILITY BASELINE(PCB) Presented By Basker George

  2. Process Database & Process Capability Baseline • Past experience play a key role in any organization for improvement & management. • This experience should be captured & organized to enable learning • This experience should be made available to others • For software projects PDB & PCB are two mechanism for encapsulating past experience for use in Project Planning & Management.

  3. Process Database & Process Capability Baseline • The PDB & PCB encapsulate (装入胶囊) the experience with previous projects. • The metrics from PDB & PCB of the previous projects is made available to fresh Project Planning & Management. • These two PROCESS are not part of the Project Planning • But provide key inputs for planning the infrastructure (基础下部组织) of the project

  4. Process Database & Process Capability Baseline • This chapter explains how these two planning support system are implemented at Infosys. • The process database is the requirement of Organization Process Focus & Organization Process Definition KPA’s of CMM Level 3. • The PCB is a requirement of Quantitative Process Management KPA & Software Quality Management KPA of Level 4.

  6. Role of Software Metrics & Process Management • Process metrics quantify attributes of the software process, such as • Productivity • Quality • Resource • Defects • Removal Efficiency of metrics

  7. Role of Software Metrics & Process Management • Product metrics are the measure of the software, such as • Size • Reliability • Quality(metrics of both Process & Product) • Complexity of code • functionality

  8. Purpose of collecting metrics • The important use of software metrics are: • Project Planning • Past data from completed projects are invaluable in developing reasonable plans for new projects & setting realistic goals for it. • Controlling a project process • Metrics can provide accurate information about the state of a project, which can then be used to take corrective

  9. Purpose of collecting metrics • Analyzing and Improving the organization’s processes. • Only through metrics can an organization know the quality & productivity • Capability of its processes & the change in quality & productivity with time. • Potential area of improvement

  10. Process Database • Process database is a collection of process performance data from different projects • The PDB is used for project planning, particularly estimation of efforts & defects. • To collect metrics on productivity & Quality from different projects • To aid in creating process capability baseline • To facilitate data analysis for identifying areas & scope of improvement

  11. Process Database DATA • The data collected in PDB can be classified as: • Project characteristic • Project schedule • Project effort • Size • Defects

  12. Project characteristic • The project characteristic are: • Name of Project, PM, PLs • Business unit to which it belongs • Process being employed • Development, Reengineering or Maintenance • Project goals, risks, duration, team size • Hardware platform, language, DBMS used

  13. Project schedule • Expected start date • Expected end date • Actual start date • Actual end date

  14. Project effort • Information on project effort include data on: • Initial estimated efforts • Total actual estimated effort • Efforts include • Project initiation, RM, Design, Built, Testing & other phases.

  15. Size • Information on size include • LOC • No of simple, medium or complex programs.

  16. Defects • Information on defects include • No of Defects found during review of • Requirement Management • Design • Code • Unit testing • & other phases

  17. Data entry & Access to PDB • PDB is owned by SEPG • Only SEPG has write access to PDB • PM’s & PL’s can only read • The input to PDB comes from project closure analysis report • The quality advisor examines to verify if data is useful for decision making & then submit the data to PBD.
