ITPEC IP April 2019 Question 98
When requirements to be defined are categorized into operational requirements and system requirements, which of the following is an operational requirement?
Explanation
Enhancing the automation of shipment activities to reduce the cost of logistics — an operational requirement states how the business itself must work.
Operational (business) requirements describe the business operations to be achieved and why, in the users' terms: which work is changed and to what end. System requirements describe what the information system must provide to support them: functions, performance, reliability, security and operability. Option (d) names a business activity and a business goal, with no system property in it.
Answer (d)
Why not others:
- •(a) — an availability of 99% or higher is a reliability requirement on the system
- •(b) — encrypting data received via the network is a security requirement on the system
- •(c) — using a Web browser for screen display is an operability (interface) requirement on the system
Key rule: If the requirement speaks of the business (cost, work, outcome) it is operational; if it speaks of properties of the system it is a system requirement.
