Software Item

Software

Computer programs and computer databases. Note: Although some definitions of software include documentation, it is now limited to the definition of computer programs and computer databases.

Software development

A set of activities that result in software products. Software development may include new development, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.

SOW

Statement of Work

Specification

A document that describes the essential technical requirements for items, materials or services including the procedures for determining whether or not the requirements have been met.

SRR

System Requirements Review

Stakeholders

The people for whom the system is being built, as well as anyone who will manage, develop, operate, maintain, use, benefit from, or otherwise be affected by the system.

Statement of Work

A document primarily for use in procurement, which specifies the work requirements for a project or program. It is used in conjunction with specifications and standards as a basis for a contract. The SOW will be used to determine whether the contractor meets stated performance requirements.

STIP

Statewide Transportation Improvement Plan

Subcontractor

An individual, partnership, corporation, or an association that contracts with an organization [i.e., the prime contractor] to design, develop, and/or manufacture one or more products.

Suppliers

The term 'suppliers' includes contractors, sub-contractors, vendors, developers, sellers or any other term used to identify the source from which products or services are obtained.

SW

Software

Synthesis

The translation of input requirements [including performance, function, and interface] into possible solutions [resources and techniques] satisfying those inputs. This defines a physical architecture of people, product, and process solutions for logical groupings of requirements [performance, functions, and interface] and their designs for those solutions.

System

An integrated composite of people, products, and processes, which provide a capability to satisfy a stated need or objective.

System elements

A system element is a balanced solution to a functional requirement or a set of functional requirements and must satisfy the performance requirements of the associated item. A system element is part of the system [hardware, software, facilities, personnel, data, material, services, and techniques] that, individually or in combination, satisfies a function [task] the system must perform.

System specification

A top level set of requirements for a system. A system specification may be a system/sub-system specification, Prime Item Development Specification, or a Critical Item Development Specification.

Systems engineering

An inter-disciplinary approach and a means to enable the realization of successful systems. Systems engineering requires a broad knowledge, a mindset that keeps the big picture in mind, a facilitator, and a skilled conductor of a team.
