Process capability Baseline Presented by Basker George

Baseline n Specification (规格) or Product (乘积) that has been formally (形式上) reviewed and agreed upon, that serves as the basis (基础) for further development.

Process Assets(资产) n n In case future projects are similar to the previous projects, the projects modules called project assets can be reused. The following assets are collected & reused through a separate system.

Process Assets n n n n Project management plan Configuration management plan Schedule Standards, checklists, guidelines, templates & other aids(帮助) Developed tools & related tools Training materials Other documents that could be reused by future projects

Process Assets n n Links to process assets are maintained in the process database. The process assets are maintained as separate files General purpose check-list, templates, forms, standards & other documents that are part of quality system are form of process assets. They are available online through web- based system.

Body of Knowledge(知识) n n Body of Knowledge (BOK) is a Knowledge Management System to leverage (杠杆作用) the collective experience to their employees. The knowledge is organized by different topics

Body of Knowledge n n n n Key topics in BOK include: Human resource development Computer & communication services Requirement Specification Build Tools Methodologies / Techniques

Body of Knowledge n n n Education & Research Other facilities Design Review / Inspection & Testing Quality assurance & Productivity Project Management

Process Capability Baseline n n n It represents the capability of the process in quantitative terms It is nothing but the range of results that can be expected if the process is followed. The focus of baseline is primarily on quality & productivity.

Process Capability Baseline n n n n The PCB at INFOSYS specifies the following: Delivered Quality Productivity Schedule Effort Distribution(配给物) Defect injection rate In process defect removal efficiency Defect distribution

Baseline Creation n n A process baseline represents the expected outcome by following the trail (踪迹) of the process. Some important Definitions: Productivity: is defined in terms of function point Quality: Delivered defects per function point

Baseline Creation n n Defect Injection Rate: total no of defects injected during the life cycle of project. Overall Defect Removal efficiency: The percentage of total defects that are detected inside the process.

Baseline Creation n n n n F=Size of software in function points E=Total effort spent in the project D 1=Total number of defects found during development. D 2=Total no of defects found after delivery D=D 1+D 2 Productivity = E/F Quality=D 2/F Defect Injection Rate= D/F Overall Defect Removal efficiency = D 1/D

Process Capability Baseline for 3 GL for Development Project Sl# Metric Remark 1 Delivered defects/FP 0. 04 -0. 09 (delivered defects=AT defects/FP(avg: 0. 06 +warranty defects) Delivered Quality General Baseline defects/FP) 2 Productivity 1 person-month=8. 5 person-hours X 22 days=187 person hours 4 -18 FP/personmonth(avg: 10 FP/personmonth)

Process Improvement & Analysis n n The PCB is used to compare previous years PCB to analyze quality & productivity. The PCB is also used to analyze defect injection rate. In general, If performance parameter differs dramatically, then attempt is made to identify the causes. PCB is also used in Process Improvement Planning.
