A requirement diagram is a diagram specially used in SysML in which requirements and the relations between them and their relationship to other model elements are shown as discussed in the following paragraphs. Demonstration of requirements diagram for a basic lessons learned system.
A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirements Document "PRD" [citation needed]. Thus it picks up the results of the requirements analysis stage. On more complex systems multiple levels of functional specifications will typically nest to each other, e.g. on the system ...
Functional requirements are supported by non-functional requirements (also known as "quality requirements"), which impose constraints on the design or implementation (such as performance requirements, security, or reliability). Generally, functional requirements are expressed in the form "system must do <requirement>," while non-functional ...
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.
the business analysts or functional analysts who document the initial decision requirements and specify the detailed decision models and decision logic, the technical developers responsible for the automation of systems that make the decisions. The DMN standard can be effectively used standalone but it is also complementary to the BPMN and CMMN ...

However, it does not determine how the software will be designed or built. Usually, the users are interviewed and a document called the user requirements document is generated. The user requirements document will typically describe the system's functional, interface, performance, data, security, etc. requirements as expected by the user.
Since features are small, completing a feature is a relatively small task. For accurate state reporting and keeping track of the software development project, it is important to mark the progress made on each feature. FDD therefore defines six milestones per feature that are to be completed sequentially.
