Use case in the context of Software requirements specification

An artifact is one of many kinds of tangible by-products produced during the development of software. Some artifacts (e.g., use cases, class diagrams, requirements and design documents) help describe the function, architecture, and design of software. Other artifacts are concerned with the process of development itself—such as project plans, business cases, and risk assessments.

The term artifact in connection with software development is largely associated with specific development methods or processes e.g., Unified Process. This usage of the term may have originated with those methods.

An actorin the Unified Modeling Language (UML) "specifies a role played by a user or any other system that interacts with the subject."

"An Actor models a type of role played by an entity that interacts with the subject (e.g., by exchanging signals and data),but which is external to the subject."

A software requirements specification (SRS) is a description of a software system to be developed. It is modeled after the business requirements specification (CONOPS). The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.

Software requirements specifications establish the basis for an agreement between customers and contractors or suppliers on how the software product should function (in a market-driven project, these roles may be played by the marketing and development divisions). Software requirements specification is a rigorous assessment of requirements before the more specific system design stages, and its goal is to reduce later redesign. It should also provide a realistic basis for estimating product costs, risks, and schedules. Used appropriately, software requirements specifications can help prevent software project failure.The software requirements specification document lists sufficient and necessary requirements for the project development. To derive the requirements, the developer needs to have a clear and thorough understanding of the products under development. This is achieved through detailed and continuous communications with the project team and customer throughout the software development process.

This subpage lists American military electronic instruments/systems along with brief descriptions. This stand-alone list specifically identifies electronic devices which are assigned designations (names) according to the Joint Electronics Type Designation System (JETDS) beginning with the AN/ prefix. They are grouped below by the first designation letter following this prefix. The list is organized as sorted tables that reflect the purpose, uses and manufacturers of each listed item.

Due to page size considerations, the full list was split into sub-pages. The list on this page only shows designations where the first letter after AN/ is between A and G. For all designations between M and Z, please see List of military electronics of the United States: M–Z.

A proof of concept (POC or PoC), also known as proof of principle, is an inchoate realization of a certain idea or method in order to demonstrate its feasibility or viability. A proof of concept is usually small and may or may not be complete, but aims to demonstrate in principle that the concept has practical potential without needing to fully develop it.

A proof of value (PoV) is sometimes used along proof of concept, and differs by focusing more on demonstrating the potential customer use case and value, and is usually less in-depth than a proof of concept.
