ITPEC FE Morning October 2023 Question 48
Which of the following is approved by the customer when the external design of a system is completed?
Explanation
Screen layout — external design defines what users see, so its user-facing outputs are what the customer reviews and approves.
External design specifies the system from the user's point of view: screens, forms, reports, input and output items, and interfaces with other systems. The customer can judge these, because they describe how the system will look and behave in their work. Internal design then turns them into technical structures (physical files and databases, program structure) that the development side decides.
Answer (c)
Why not others:
- •(a) Physical database specification — a product of internal design; it concerns storage and access methods the customer does not review
- •(b) Program flowchart — a product of program design, internal to development
- •(d) System development plan — drawn up in planning, before design starts, so it is not a deliverable of external design
Key rule: External design is judged by the user (screens, reports, codes seen by users); internal and program design are technical and stay with the developers.
