Feature-driven development is built on a core set of software engineering best practices aimed at a client-valued feature perspective. Domain object modelling. Domain object modeling consists of exploring and explaining the domain of the problem to be solved. The resulting domain object model provides an overall framework in which to add features.
A functional specification (also, functional spec, specs, functional specifications document (FSD), functional requirements specification) in systems engineering and software development is a document that specifies the functions that a system or component must perform (often part of a requirements specification) (ISO/IEC/IEEE 24765-2010).
The design of a program is a named expression, e.g.: p 1 = j + f -- program p 1 has features j and f p 2 = j + h -- program p 2 has features j and h p 3 = i + j + h -- program p 3 has features i, j, and h A GenVoca model of a domain or software product line is a collection of base programs and features (see MetaModels and Program Cubes). The ...
Generally, functional requirements are expressed in the form "system must do <requirement>," while non-functional requirements take the form "system shall be <requirement>." [3] The plan for implementing functional requirements is detailed in the system design, whereas non-functional requirements are detailed in the system architecture. [4] [5]
Business requirements in the context of software engineering or the software development life cycle, is the concept of eliciting and documenting business requirements of business users such as customers, employees, and vendors early in the development cycle of a system to guide the design of the future system.
[1] [2] The trend towards agile methods in software engineering is noticeable, [3] however the need for improved studies on the subject is also paramount. [4] [5] Also note that some of the methods listed might be newer or older or still in use or out-dated, and the research on software design methods is not new and on-going. [6] [7] [8] [9]

A key aspect of specification by example is creating a single source of truth about required changes from all perspectives. When business analysts work on their own documents, software developers maintain their own documentation and testers maintain a separate set of functional tests, software delivery effectiveness is significantly reduced by the need to constantly coordinate and synchronise ...
