| Sampling Factors: |
Location (Not Relevant: All projects are done in single location in Shenzhen, hence is not a relevant sampling factor.)
Customer (Not Relevant: The same customer type for all basic units, hence is not relevant sampling factor.)
Size (Not Relevant: All projects are almost of the same scale with 7 to 8 developers in the project team, hence is not a relevant sampling factor)
Organizational Structure (Not Relevant: All team reports to one senior manager and all basic units belong to one technology department, hence is not a relevant factor.)
Type of Work (Not Relevant: All projects are development projects using Java following the same process.)
Life Cycle: There are two types of life cycle (waterfall and v-life cycle |
| Sampling Factor Values: |
Waterfall Life Cycle (Life Cycle): For projects with clear requirements
V-Life Cycle (Life Cycle): Projects with high quality requirements |
| Subgroups: |
Waterfall * Subgroup 1: This is a life cycle used by the projects using I Waterfall
28 People, 4 Basic Units
– Waterfall Life Cycle
V-shape Life Cycle Subgroup 2: This is a life cycle used by the projects using V-shape if requirement not so clear
7 People, 1 Basic Units
– V-Life Cycle |
