ITPEC IP October 2021 Question 97
ITPEC IP October 2021 — Question 97 of 100
Requirements definition clarifies the business functions to be created or revised and specifies the system's computerization scope and required functions. It establishes what the system must accomplish before designers decide how to implement it.
Answer (d)
Why not others:
- external design describes user-visible behavior based on established requirements
- internal design determines the system's internal structure and processing details
- programming implements the design as executable code
Key rule: Requirements definition states what is needed and why; design and programming determine how it will be realized.
