ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide chapter ۵ software requirements ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide software requirements descriptions and specifications of a system ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide objectives to introduce the concepts of user and system requirements to describe functional and non functional requirements to explain two techniques for describing system requirements to explain how software requirements may be organised in a requirements document ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide topics covered functional and non functional requirements user requirements system requirements the software requirements document ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide requirements engineering the process of establishing the services that the customer requires from a system and the constraints under which it operates and is developed the requirements themselves are the descriptions of the system services and constraints that are generated during the requirements engineering process ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide what is a requirement it may range from a high level abstract statement of a service or of a system constraint to a detailed mathematical functional specification this is inevitable as requirements may serve a dual function may be the basis for a bid for a contract therefore must be open to interpretation may be the basis for the contract itself therefore must be defined in detail both these statements may be called requirements ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide requirements abstraction davis if a company wishes to let a contract for a large software development project it must define its needs in a sufficiently abstract way that a solution is not pre defined. the requirements must be written so that several contractors can bid for the contract offering perhaps different ways of meeting the client organisation’s needs. once a contract has been awarded the contractor must write a system definition for the client in more detail so that the client understands and can validate what the software will do. both of these documents may be called the requirements document for the system. ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide types of requirement user requirements statements in natural language plus diagrams of the services the system provides and its operational constraints. written for customers system requirements a structured document setting out detailed descriptions of the system services. written as a contract between client and contractor software specification a detailed software description which can serve as a basis for a design or implementation. written for developers ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide definitions and specifications ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide requirements readers ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide functional and non functional requirements functional requirements statements of services the system should provide how the system should react to particular inputs and how the system should behave in particular situations. non functional requirements constraints on the services or functions offered by the system such as timing constraints constraints on the development process standards etc. domain requirements requirements that come from the application domain of the system and that reflect characteristics of that domain ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide functional requirements describe functionality or system services depend on the type of software expected users and the type of system where the software is used functional user requirements may be high level statements of what the system should do but functional system requirements should describe the system services in detail ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide examples of functional requirements the user shall be able to search either all of the initial set of databases or select a subset from it. the system shall provide appropriate viewers for the user to read documents in the document store. every order shall be allocated a unique identifier order id which the user shall be able to copy to the account’s permanent storage area. ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide requirements imprecision problems arise when requirements are not precisely stated ambiguous requirements may be interpreted in different ways by developers and users consider the term ‘appropriate viewers’ user intention special purpose viewer for each different document type developer interpretation provide a text viewer that shows the contents of the document ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide requirements completeness and consistency in principle requirements should be both complete and consistent complete they should include descriptions of all facilities required consistent there should be no conflicts or contradictions in the descriptions of the system facilities in practice it is impossible to produce a complete and consistent requirements document ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide non functional requirements define system properties and constraints e.g. reliability response time and storage requirements. constraints are i o device capability system representations etc. process requirements may also be specified mandating a particular case system programming language or development method non functional requirements may be more critical than functional requirements. if these are not met the system is useless ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide non functional classifications product requirements requirements which specify that the delivered product must behave in a particular way e.g. execution speed reliability etc. organisational requirements requirements which are a consequence of organisational policies and procedures e.g. process standards used implementation requirements etc. external requirements requirements which arise from factors which are external to the system and its development process e.g. interoperability requirements legislative requirements etc. ian sommerville ۲ software engineering ۶th edition. chapter ۵ slide non functional requirement types ian sommerville ۲ software engineering ۶th edition. …
