VSE - Very Small Entities

Very small entities (VSE) software standards are published by ISO and IEC. They cover the 29110 series, which covers overview, framework and taxonomy, process assessment guidelines, generic profile groups, entry profile, and basic profile.

ISO/IEC TR 29110-1:2016

Systems and software engineering - Lifecycle profiles for Very Small Entities (VSEs) - Part 1: Overview

ISO/IEC TR 29110-1:2016 introduces the major concepts required to understand and use the ISO/IEC 29110 series. It introduces the characteristics and requirements of a VSE and clarifies the rationale for VSE-specific profiles, documents, standards and guides. It also introduces process, lifecycle, standardization concepts and defines the organizational terms common to the VSE Profile Set of Documents. It is applicable to a VSE. A VSE is an entity (enterprise, organization, department or project) having up to 25 people. The lifecycle processes described in the ISO/IEC 29110 series, Standardized Profiles and Technical Reports are not intended to preclude nor discourage their use by an entity that is larger than a VSE. It is targeted both at the general audience wishing to understand the series of documents and, more specifically, at users of the ISO/IEC 29110 series. It should be read first when initially exploring VSE Profile documents. While there is no specific prerequisite to read this part of ISO/IEC 29110, it will be helpful to the user in understanding the other parts. The lifecycle processes defined in the set of Standardized Profiles and Technical Reports can be used by a VSE when developing, acquiring and using, as well as when creating and supplying systems having hardware and software elements and software. They can be applied at any level in a systems development, software system's structure and at any stage in the lifecycle. They are not intended to preclude or discourage the use of additional processes that a VSE finds useful.

Software Engineering - Lifecycle profiles for Very Small Entities (VSEs) - Part 2-1: Framework and taxonomy

1.1 Fields of application ISO/IEC 29110-2-1:2015 is applicable to Very Small Entities (VSEs). The lifecycle processes described in ISO/IEC 29110 are not intended to preclude or discourage their use by organizations bigger than VSEs. However, certain issues faced by large organizations might not be covered by ISO/IEC 29110. The lifecycle processes defined in ISO/IEC 29110 can be used by VSEs when acquiring and using, as well as when creating and supplying, a software, and systems. They can be applied at any level in a software and systems structure and at any stage in the lifecycle. The processes described in ISO/IEC 29110 are not intended to preclude or discourage the use of additional processes that VSEs find useful. ISO/IEC 29110-2-1:2015 introduces the major concepts for software and systems engineering profiles for VSEs, and defines the terms common to the set of documents associated with VSE profiles. It establishes the logic behind the definition and application of profiles. It specifies the elements common to all standardized profiles (structure, conformance, assessment). ISO/IEC 29110-2-1:2015 is applicable to all profiles. 1.2 Target audience ISO/IEC 29110-2-1:2015 is targeted at authors and reviewers of standardized profiles, authors of other parts, and authors of other VSE profiles.

Systems and software engineering - Lifecycle profiles for Very Small Entities (VSEs) - Part 4-1: Software engineering - Profile specifications: Generic profile group

ISO/IEC 29110-4-1:2018 series is applicable to Very Small Entities (VSEs). VSEs are enterprises, organizations, departments or projects having up to 25 people. The lifecycle processes described in the ISO/IEC 29110 series are not intended to preclude or discourage their use by larger organizations than VSEs. The lifecycle processes defined in the ISO/IEC 29110 series can be used by VSEs when using, as well as when creating and supplying, a software system. They can be applied at any level in a software system's structure and at any stage in the lifecycle. The processes described in the ISO/IEC 29110 series are not intended to preclude or discourage the use of additional processes that VSEs find useful. This document is not intended to preclude the use of different life cycles such as: waterfall, iterative, incremental, evolutionary or agile. ISO/IEC 29110-4-1:2018 provides a profile specification for the Basic profile. The Basic profile applies to VSEs involved in software development. It selects ISO/IEC/IEEE 12207 project management and software implementation process elements from the single project perspective. ISO/IEC 29110-4-1:2018 provides the normative and informative links to the subset of ISO/IEC/IEEE 12207.

ISO/IEC TR 29110-5-1-1:2012

Software engineering - Lifecycle profiles for Very Small Entities (VSEs) - Part 5-1-1: Management and engineering guide: Generic profile group: Entry profile

ISO/IEC TR 29110-5-1-1:2012 is applicable to Very Small Entities (VSEs). VSEs are enterprises, organizations, departments or projects up to 25 people. The life cycle processes described in the set of International Standards (IS) Profiles and Technical Reports (TR) are not intended to preclude or discourage their use by organizations bigger than VSEs. ISO/IEC TR 29110-5-1-1:2012 provides the management and engineering guide to the entry profile described in ISO/IEC 29110-4-1 through project management and software implementation processes. ISO/IEC TR 29110 5 1 1:2012 is a stand-alone guide. It is not intended for a VSE to use the standardized profile to implement ISO/IEC TR 29110-5-1-1:2012. ISO/IEC TR 29110-5-1-1:2012 applies for software development project. The project may be to fulfil an external or internal contract. The internal contract need not be explicit between the project team and their customer. Using ISO/IEC TR 29110-5-1-1:2012, a VSE can obtain the following benefits: 1) an agreed set of project requirements and expected products is delivered to the customer; 2) a disciplined management process, that provides project visibility and corrective actions of project problems and deviations, is performed; 3) a systematic software implementation process, that satisfies customer needs and ensures quality products, is followed. ISO/IEC TR 29110-5-1-1:2012 is targeted at VSEs (a start-up VSE that started the operation less than 3 years ago and/or with a project size less than 6 person-months). It is intended to be used with any processes, techniques and methods that enhance the VSE's customer satisfaction and productivity.
