1Requirements specificationThis section discusses the functional and non-functional requirements of the proposed Collin’s car park system.a.Functional requirementsFunctional requirements are requirements specified by the user of the system to help them perform various tasks using the system (Ambler, 2018). They specify how the user interacts with the system to perform various tasks defined within the scope of the system. Collin’s car park system has different type of users that interact with the system. These users include the customers i.e. fixed and ordinary customers and the security persons who perform schedules security checks in the car parks. The proposed system manages the usage of the car park by the users. The following are the functional requirements for the proposed car park system.Requirement IDDescriptionUserinputExpected result1An ordinary customer enters the car park.
