Consider the integration and configuration process model shown in Figure 2.3. Explain why it is essential to repeat the requirements engineering activity in the process.
What will be an ideal response?
You need to repeat the requirements engineering activity because it is essential to
adapt the system requirements according to the capabilities of the
system/components to be reused. These activities are:
1. An initial activity where you understand the function of the system and set
out broad requirements for what the system should do. These should be
expressed in sufficient detail that you can use them as a basis for deciding of
a system/component satisfies some of the requirements and so can be
reused.
2. Once systems/components have been selected, you need a more detailed
requirements engineering activity to check that the features of the reused
software meet the business needs and to identify changes and additions that
are required.
