| Sampling Factors: |
Location (Not Relevant: All project work is done in the same building and therefore location does not have an influence on processes.)
Customer (Not Relevant: Engineering work is defined by the product and not the customer, products are identically sold to different customer)
Size (Not Relevant: The size of the projects are all similar (5 to 7 persons) and therefore size does not impact on process selection.)
Organizational Structure (Not Relevant: All engineering for all products is done in the same department with the same team and project organization.)
Type of Work (Not Relevant: All projects develop software products)
Requirements Stability: In some projects requirements are stable, in some they are frequently changed. Therefore the organization uses two life cycle models: Waterfall and Iterative |
| Sampling Factor Values: |
Waterfall (Requirements Stability): Requirements are stable and so a product is developed in a single step with a single delivery
Iterative (Requirements Stability): Requirements for a product are not stable or are expected to be not stable. Such a product is planned to be implemented and delivered in several relaases |
| Subgroups: |
Waterfall: A product is developed in a single step with a final delivery
24 People, 4 Basic Units
– Waterfall
Iterative: A product is developed in multiple steps with intermediate deliveries
11 People, 2 Basic Units
– Iterative |
