Question

If your customer states that there is a system requirement that the System of Interest (SoI) must perform a task to navigate to specific named locations in a store, which leads to another requirement (unstated by the customer) that the system must access a database that contains the names of the locations and their respective locations (grid coordinates). What type of relationship exists between the two requirements?

Answer 1

Requirement Engineering: Requirements are the key to any software.the process of software engineering starts from requirements. In the early days analyzing the requirements will be not so tough. but now requirements need to engineer them for better standards and enhancements.

• After gathering the requirements, the team will study them and find the interdependencies between the relationships.
• the relations between the requirements are quite common.
• As we study the above example, the customer mentioned requirements lead to another requirement.
• Based on requirement traceability, there 4 types of relationships between the requirements. those are listed below.
• DERIVE: means one requirement derives other requirement.
• ELABORATE: means sometimes the developer needs to elaborate on the basic requirement to fulfill the future enhancements.
• DEPEND ON: In this relationship, the requirements depend on the other requirements like software, hardware.
• PART OF: some complex requirements can be broken into small requirements.

In the above example, the two requirements are derived from customer requirements.the customer needs a navigation system in the store. which derives another requirement to keep a track of the locations.

i.e., the relationship between the requirements is DERIVE.
