Presented By Basker George

process database process capability baseline
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.
process database process capability baseline1
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
process database process capability baseline2
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.

role of software metrics process management
Role of Software Metrics & Process Management
  • Process metrics quantify attributes of the software process, such as
    • Productivity
    • Quality
    • Resource
    • Defects
    • Removal Efficiency of metrics
role of software metrics process management1
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
purpose of collecting metrics
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
purpose of collecting metrics1
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
process database
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
process database data
Process Database DATA
  • The data collected in PDB can be classified as:
    • Project characteristic
    • Project schedule
    • Project effort
    • Size
    • Defects
project characteristic
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
project schedule
Project schedule
  • Expected start date
  • Expected end date
  • Actual start date
  • Actual end date
project effort
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.
  • Information on size include
    • LOC
    • No of simple, medium or complex programs.
  • Information on defects include
    • No of Defects found during review of
      • Requirement Management
      • Design
      • Code
      • Unit testing
      • & other phases
data entry access to pdb
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.
