Abstract-Very small entities, organizations with up to 25 people, are very important to the worldwide economy. However it has ben established that such companies often do not utilize existing best practice standards and frameworks. To address the needs of Very Small Entities (VSEs), a set of international standards and guides known as ISO/IEC 29110 has been developed. In this paper we present the results of early trials of this standard in an IT start-up and in an engineering enterprise and assess the lessons learnt for future research and industrial usage of this standard.
Industry recognizes that there are very small organizations that develop parts which contain software components. These organizations, those with up to 25 people, are very important to the world-wide economy, and the parts they develop are often integrated into products made by larger enterprises. Failure to deliver a quality product on time and within budget threatens the competitiveness of both organizations. One way to mitigate these risks is for all the suppliers in a product chain put in place proven engineering practices. Many international standards have been developed to capture such proven engineering practices. However, these standards were not written for very small development organizations and are consequently difficult to apply in such settings. An ISO Working Group has been established to address these difficulties. The working group developed standards and technical reports, ISO/IEC 29110, which were published in 2011 for organizations developing software. In 2009 an INCOSE working group was established to evaluate the possibility of developing a standard, using the ISO/IEC 29110 standard as a baseline and the ISO/IEC 15288 as the framework, for organizations developing systems. At the 2011 INCOSE International Workshop, a group of systems engineers reviewed the ISO/IEC 29110 software standard and proposed modifications to meet their needs. One constraint was to develop a document which will allow an organization developing systems with software components to be able to use the actual set of ISO/IEC 29110 standards as well as the proposed systems engineering standards. The future systems engineering standard is targeted at VSEs which do not have experience or expertise in tailoring ISO/IEC 15288. A draft document has been developed and reviewed. Recently, an ISO working group has been mandated to develop the ISO standard for very small organizations developing systems. The INCOSE Systems Engineering Handbook is used as the main reference for the development of a set of systems engineering deployment packages. A deployment package is a set of artefacts developed to facilitate the implementation of a set of practices of a standard in a very small organization. IntroductionToday, the ability of organizations to compete, adapt, and survive depends increasingly on software. In 2010 a cellular phone contained 20 million lines of code and some cars had up to 100 million lines of code (Charette 2005). Manufacturers depend increasingly on the components produced by their suppliers. A manufacturing chain of large mass-market products often has a pyramidal structure, as illustrated in Figure 1. For example, a large mass product manufacturer recently integrated into one of its products a part with an unknown software error that was produced by one of its 6,000 lower-level producers. This defective part resulted in a loss of over $200 million by the mass product manufacturer. There is a need to help these VSEs understand the benefit of the concepts, processes, and practices described in international...

International standards capture proven engineering practices for systems engineering and software engineering development. The perception by very small entities (VSEs) is that these standards are developed and targeted for use by large enterprises. However, governments and industry alike recognizes that VSEs, consisting of 25 staff members or less, constitute a majority of the systems and software developers throughout the world. During a world‐wide survey of many different domain VSEs, it was verified that existing ISO standards were “too complicated” for use by VSEs. In 2005, the first meeting of ISO/IEC JTC1 SC7 Working Group (WG) 24 was held. This ISO WG is mandated to develop standards and guides for VSE use, thus the work on the ISO/IEC 29110 series began. The paper will address how the ISO/IEC 29110 series and the INCOSE VSE WG deployment packages (DPs) work collaboratively to help VSEs incorporate systems engineering concepts within their entities. The use of these systems engineering concepts can provide VSEs the opportunity to successfully participate and grow in the global market environment.
