| Sampling Factors: |
Location (Not Relevant: Projects are always developed in a multisite approach taking advantage of the availability of the workforce, at any place, and offering the added value of large support to customer, based on the overlap of the time slots)
Customer (Not Relevant: Operational processes are always based on the same set processes following the standard tailoring guidelines)
Size (Not Relevant: All the projects developed by the company follow the operational processes in a similar manner)
Organizational Structure (Not Relevant: Structure is common in the Department, having the direct delivery team, supported by the PEG and the HM Teams, the Release and CM Team and the Training support)
Type of Work (Not Relevant: The organization is involved in developing projects for final customers. Support activities and product development and evolution is taken over by separated teams)
Product Base: The projects may be based on two different products, TOMS and RBM, covering OSS and BSS stacks
Life Cycle: The projects may follow either the complete life cycle, or start from requirements supplied by the customer or by a third system integrator directly
Validation/Requirements capturing approa: Validation/Requirements capturing may be done with an intensive use of prototypes and hands on activity during workshops, or through a structured set of workshops and working sessions, without the use of working prototypes |
| Sampling Factor Values: |
TOMS (Product Base): OSS stack system
RBM (Product Base): BSS stack system
Greenfield (Life Cycle): Complete life cycle
Brownfield (Life Cycle): Reduced life cycle, with requirements engineering under the responsibility of the customer
Hands-on Validation (Validation/Requirements capturing approa): Initial validation and requirements elicitation through the use of prototypes
Standard Validation (Validation/Requirements capturing approa): Standard elicitation process |
