21、y Small Entities (VSEs) around the world are creating valuable products and services. For the purpose of this part of ISO/IEC 29110, a Very Small Entity (VSE) is an enterprise, an organization, a department, or a project having up to 25 people. Since many VSEs develop and/or maintain system and soft
22、ware components used in systems, either as independent products or incorporated in larger systems, a recognition of VSEs as suppliers of high quality products is required. According to the Organization for Economic Co-operation and Development (OECD) SME and Entrepreneurship Outlook report (2005), “
23、Small and Medium Enterprises (SMEs) constitute the dominant form of business organization in all countries world-wide, accounting for over 95 % and up to 99 % of the business population depending on country”. The challenge facing governments and economies is to provide a business environment that su
24、pports the competitiveness of this large heterogeneous business population and that promotes a vibrant entrepreneurial culture. From studies and surveys conducted, it is clear that the majority of International Standards do not address the needs of VSEs. Implementation of and conformance with these
25、standards is difficult, if not impossible. Consequently, VSEs have no, or very limited, ways to be recognized as entities that produce quality systems/system elements including software in their domain. Therefore, VSEs are excluded from some economic activities. It has been found that VSEs find it d
26、ifficult to relate International Standards to their business needs and to justify the effort required to apply standards to their business practices. Most VSEs can neither afford the resources, in terms of number of employees, expertise, budget, and time, nor do they see a net benefit in establishin
27、g over-complex systems or software lifecycle processes. To address some of these difficulties, a set of guides has been developed based on a set of VSE characteristics. The guides are based on subsets of appropriate standards processes, activities, tasks, and outcomes, referred to as Profiles. The p
28、urpose of a profile is to define a subset of International Standards relevant to the VSEs context; for example, processes, activities, tasks, and outcomes of ISO/IEC/IEEE 12207 for software; and processes, activities, tasks, and outcomes of ISO/IEC/IEEE 15288 for systems; and information products (d
29、ocumentation) of ISO/IEC/IEEE 15289 for software and systems. VSEs can achieve recognition through implementing a profile and by being audited against ISO/IEC 29110 specifications. The ISO/IEC 29110 series of International Standards and Technical Reports can be applied at any phase of system or soft
30、ware development within a lifecycle. This series of International Standards and Technical Reports is intended to be used by VSEs that do not have experience or expertise in adapting/tailoring ISO/IEC/IEEE 12207 or ISO/IEC/IEEE 15288 standards to the needs of a specific project. VSEs that have expert
31、ise in adapting/tailoring ISO/IEC/IEEE 12207 or ISO/IEC/IEEE 15288 are encouraged to use those standards instead of ISO/IEC 29110. ISO/IEC 29110 is intended to be used with any lifecycle such as: waterfall, iterative, incremental, evolutionary, or agile. The ISO/IEC 29110 series, targeted by audienc
32、e, has been developed to improve system or software and/or service quality, and process performance (see Table 1).vi ISO/IEC 2015 All rights reserved ISO/IEC 29110-2-1:2015(E) Table 1 ISO/IEC 29110 target audience ISO/IEC 29110 Title Target audience Part 1 Overview VSEs and their customers, assessor
33、s, standards producers, tool vendors, and methodology vendors. Part 2 Framework Profile producers, tool vendors, and methodology vendors. Not intended for VSEs. Part 3 Assessment guide VSEs and their customers, assessors, accreditation bodies. Part 4 Profile specifications VSEs, customers, standards
34、 produc- ers, tool vendors, and methodology vendors. Part 5 Management and engi- neering guide VSEs and their customers. If a new profile is needed, ISO/IEC 29110-4 and ISO/IEC TR 29110-5 can be developed with minimal impact to existing documents. ISO/IEC TR 29110-1 defines the terms common to the I
35、SO/IEC 29110 series. It introduces processes, lifecycle, and standardization concepts, the taxonomy (catalogue) of ISO/IEC 29110 profiles, and the ISO/IEC 29110 series. It also introduces the characteristics and needs of a VSE, and clarifies the rationale for specific profiles, documents, standards,
36、 and guides. ISO/IEC TR 29110-3 defines certification schemes, assessment guidelines, and compliance requirements for process capability assessment (ISO/IEC 33xxx), conformity assessments (ISO/IEC 17xxx), and self-assessments for process improvements. ISO/IEC TR 29110-3 also contains information tha
37、t can be useful to developers of certification and assessment methods and developers of certification and assessment tools. ISO/IEC 29110-3 is addressed to people who have direct involvement with the assessment process, e.g. the auditor, certification, and accreditation bodies and the sponsor of the
38、 audit, who need guidance on ensuring that the requirements for performing an audit have been met. ISO/IEC 29110-4-m provides the specification for all profiles in one profile group that are based on subsets of appropriate standards elements. ISO/IEC TR 29110-5-m-n provides a management and engineer
39、ing guide for each profile in one profile group. ISO/IEC TR 29110-6-x provides management and engineering guides not tied to a specific profile. This part of ISO/IEC 29110 introduces the concepts for systems and software engineering profiles for VSEs. It establishes the logic behind the definition a
40、nd application of profiles. For standardized profiles, it specifies the elements common to all profiles (structure, requirements, conformance, and assessment). For domain-specific profiles (profiles that are not standardized and developed outside of the ISO process), it provides general guidance ada
41、pted from the definition of standardized profiles. Figure 1 describes the International Standards (IS) and Technical Reports (TR) of ISO/IEC 29110 and positions the parts within the framework of reference. Overview, assessment guide, management, and engineering guide are available from ISO as freely
42、 available Technical Reports (TR). The Framework document, profile specifications and certification schemes are published as International Standards (IS).

43、ering Lifecycle profiles for Very Small Entities (VSEs) Part 2-1: Framework and taxonomy 1 Scope 1.1 Fields of application ISO/IEC 29110 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 organizatio
44、ns 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
45、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. This part of ISO/IEC 29110 introduces the major concepts for software and systems en
46、gineering 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). This part of
47、 ISO/IEC 29110 is applicable to all profiles. 1.2 Target audience This part of ISO/IEC 29110 is targeted at authors and reviewers of standardized profiles, authors of other parts, and authors of other VSE profiles. 2 Conformance to standardized profiles 2.1 Overview Conformance is specified within e
48、ach profile specification document, published as ISO/IEC 29110-4-6 1)for systems engineering and ISO/IEC 29110-4-1 for software engineering. The general rules for conformance to ISO/IEC 29110 profiles are in accordance with ISO/IEC TR 10000-1 and outlined in 2.2 and 2.3. 2.2 General principles 2.2.1
49、 Tailoring and exclusions ISO/IEC 29110 standardized profiles are pre-tailored packages of related software and systems engineering standards, therefore tailoring of ISO/IEC 29110 profiles is not needed nor allowed (except in one case outlined in 2.3.2), partial compliance is not allowed (except in one case outlined in 2.2.3), and 1) To be published.
