Toward an Agile Approach to Managing the Effect of Requirements on Software Architecture during Global Software Development

Table 3

Questionnaire details against each hypothesis.

Variable	Question	Rating scale	Numeric mapping
A	Do the requirements tend to provide better coverage when stored in the form of cases in the case-based repository?	1	Failed coverage
		5	Full coverage
		B	Does Twin Peaks in the proposed approach provide better requirement and architecture synchronization?	1	Complete failure
5	Full synchronization
C	While using agile, does breaking the architecture into small sprints provide better change management?			1	Not at all
		5	Excellent management
		D	Does the use of a case-based repository increase the complexity of case retrieval, thus hindering requirement change management?	1	Don’t know
2	Up to 25%
3	26–50%
4	51–75%
5	76–100%
E	Is the relationship between dependent and independent variables covered properly?	1	Don’t know
		2	Up to 25%
		3	26–50%
		4	51–75%
		5	76–100%
F	Does agile practice during GSD lack synchronization between changing requirements and architecture?	1	Don’t know
		2	Up to 25%
		3	26–50%
		4	51–75%
		5	76–100%
G	Is there any difference between requirement and architecture management from the conventional to the distributed case-based repository approach?	1	Less than 20%
		2	Less than 40%
		3	Less than 60%
		4	Less than 80%
		5	Less than 100%
