| Sampling Factors: |
Location (Not Relevant: All projects are working in the same location in Shijiazhuang, so this is not a relevant sampling factor.)
Customer (Not Relevant: Work is not performed differently depending on the customer served by that work.)
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 lifecycle models: Waterfall Development and Iterative and Incremental Development. |
| Sampling Factor Values: |
Waterfall Development (Type of Work): Projects are developed based on Waterfall Model including phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation and Maintenance
Iterative and Incremental Development (Type of Work): Projects are developed based on Iterative Model where system functionality is managed into increments. Development begins by specifying and implementing just part of the software, which can then be reviewed in order to identify further requirements. |
