| Sampling Factors: |
Location (Not Relevant: All projects are working in the same location in Beijing, so this is not a relevant sampling factor.)
Customer (Not Relevant: Standard processes defined at organization level are uniformly implemented across every customer to ensure consistent outcome in quality and customer experience.)
Size (Not Relevant: All projects are not significantly different in size, so this is not a relevant sampling factor.)
Organizational Structure (Not Relevant: All projects are working under the same organization and management structure, so organizational structure is not a relevant sampling factor.)
Type of Work: Projects are based on two different types of work: Waterfall Development and Iterative and Incremental Development. |
| Sampling Factor Values: |
Waterfall Development (Type of Work): Projects are developed based on waterfall lifecycle model through the phases of initiation, analysis, design, development, testing, and maintenance.
Iterative and Incremental Development (Type of Work): Projects are developed based on iterative and incremental lifecycle model planning through iterative development cycles involving continuous user feedback. |
| Subgroups: |
