Explain the difference between functional requirements and system design requirements.

Solution

The difference between functional requirements and system design requirements are:

-> Functional requirements are the requirements which are related to the technical functionality of the system whereas system design requirements deals with the performance of the system in the peak hours and the time taken for the system to retrieve data from DB, security of the user data, ability of the system to handle if large number of users login.

-> The functional requirement is from client to developer side that is regarding functionality to the user by the software and system design requirement is from developer to client i.e. the requirement is not given by client but it is provided by developer to run the system smoothly.

-> Generally the functional requirement will contain a unique name and number, a brief summary, and a rationale. This information is used to help the reader understand why the requirement is needed, and to track the requirement through the development of the system. whereas the system design requirement place restrictions on the product being developed, the development process, and specify external constraints that the product must meet.
