The Evolution of the ISO/IEC 29110 set of standards and guides

While the quality of products is a competitive advantage for very small software development organizations, the usage of Software and Systems Engineering standards amongst such very small organizations is extremely low. A key factor in the literature explaining this lack of quality standards adoption is the perception by small and very small organizations that such standards have been developed for large multi-national companies and not with small and very small organizations in mind. The ISO/IEC 29110 standard is unique amongst software and systems engineering standards, in that the working group (ISO/IEC JTC1/SC7 WG 24) mandated to develop a new standard approached industry to conduct a needs assessment and gather actual requirements for a new standard as part of the standards development process. This paper presents a historical perspective behind the development of the ISO/IEC 29110 systems and software engineering standard and its constituent components, including the rationale behind its development and the innovative design of implementation guides to assist very small companies in adopting the standards. Further this paper will present an overview of the various parts of the ISO/IEC 29110 family and briefly present the plans for the future evolution of this series of standards

Software project management with ISO/IEC 29110

The recently published ISO/IEC 29110 standard Lifecycle profiles for Very Small Entities has at its core a Management and Engineering Guide [1] which are targeted at very small entities (enterprises, organizations, departments or projects) having up to 25 people [2], to assist them unlock the potential benefits of using standards which are specifically designed to address their needs. This paper discusses the role and structure of Project Management in the emerging ISO/IEC 29110 standard Software Process Lifecycles for Very Small Entities as well as its practical implication. This paper will also focus on the design and development of project management support documentation and their associated usage in early trials of ISO/IEC 29110

Software process improvement in graduate software engineering programs

At the École de technologie supérieure (ÉTS), software process improvement (SPI) is taught in lecture format and with a 10-week implementation project in an organization by teams of students of the graduate software engineering curriculum. The SPI course is taught using a ‘problem- goal-solution’ approach where students learn that any process improvement initiative must be based on issues preventing an organization in achieving its organizational goals whether the organization is a company or a not-for- profit organization. An important aspect of this course is the management of technological change where students learn and put in practice in their project the ‘soft’ issues which are part of most SPI organizational initiatives

Towards Experience Management for Very Small Entities

International audienceThe ISO/IEC 29110 standard: Lifecycle profiles for Very Small Entities, provides several Process Reference Models applicable to the vast majority of very small entities (defined by the ISO as "an entity (enterprise, organization, department or project) having up to 25 people") which do not develop critical software and share typical situational factors. An ISO/IEC 29110 pilot project has been established between the Software Engineering group at Brest University and a 14-employee company with the aim of establishing an engineering discipline for a new Web-based project. As the project proceeded, it became apparent that setting up the ISO/IEC 29110 standard has to be performed in two steps: 1) provide self-training materials to the VSE employees on this new standard; and 2) support good practices with a simple Experience Management system which is compatible with the ISO/IEC 29110 standard. This paper reports the lessons learned about training from the pilot project, and addresses the research issues associated with the Experience Management system

Experience Management for Very Small Entities: Improving the Copy-paste Model

International audienceThe emerging ISO/IEC 29110 standard Lifecycle profiles for Very Small Entities is developing a "Generic" profile group applicable to a vast majority of very small entities (enterprises, organizations, departments or projects) having up to 25 people, that do not develop critical software and have typical situational factors. The developers of the standard, ISO/IEC JCT1/SC7 Working Group 24, recommended the use of pilot projects as a mean to trial the adoption of the new International standard in small organizations. Accordingly an ISO/IEC 29110 pilot project has been established between the Software Engineering group of Brest University and a 14-person company with the aim of establishing an engineering discipline for a new web-based project. As the project proceeded, it became apparent that the current set of ISO/IEC 29110 documents describing a first profile, the Basic profile, was not sufficient to sustain this VSE in its SE activities. What was needed was to organize the knowledge contained in them. The results of this pilot study are providing VSEs with a simple Experience Management system which is compatible with the emerging ISO/IEC 29110 standard. It is founded on two principles: 1) keeping the Content Management System-based Experience Management infrastructure as simple as possible, structured with the decomposition of the ISO/IEC 29110 processes; and 2) the requirement of Experience Management dedicated processes, taken from D. Schon's work on the reflection-on-action approach to learning

Software engineering standards and guides for very small entities: implementation in two start-ups

Very small entities, enterprises, organizations, projects or departments with up to 25 people, are very important to the worldwide economy. However it has ben established that such entities often do not utilize existing 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 two IT start-ups VSEs. A Peruvian VSE was recently audited and issued an ISO/IEC 29110 certificate of conformity

An innovative approach in developing standard professionals by involving software engineering students in implementing and improving international standards

Today, the ability of organizations to compete, adapt, and survive depends increasingly on software. Some cellular phones, for example, contain over twenty million lines of code, and top of the line automobiles may have up to 100 million lines of code.1 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, adapted from Shintani. For example, a large mass product manufacturer 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. A vast majority of these low level suppliers are very small entities

CD40 deficiency mitigates Alzheimer's disease pathology in transgenic mouse models

We have previously shown that transgenic mice carrying a mutant human APP but deficient in CD40L, display a decrease in astrocytosis and microgliosis associated with a lower amount of deposited Aβ. Furthermore, an anti-CD40L treatment causes a diminution of Aβ pathology in the brain and an improved performance in several cognitive tasks in the double transgenic PSAPP mouse model. Although these data suggest a potential role for CD40L in Alzheimer's disease pathology in transgenic mice they do not cast light on whether this effect is due to inhibition of signaling via CD40 or whether it is due to the mitigation of some other unknown role of CD40L. In the present report we have generated APP and PSAPP mouse models with a disrupted CD40 gene and compared the pathological features (such as amyloid burden, astrocytosis and microgliosis that are typical of Alzheimer's disease-like pathology in these transgenic mouse strains) with appropriate controls. We find that all these features are reduced in mouse models deficient for CD40 compared with their littermates where CD40 is present. These data suggest that CD40 signaling is required to allow the full repertoire of AD-like pathology in these mice and that inhibition of the CD40 signaling pathway is a potential therapeutic strategy in Alzheimer's disease

Inhibition of bone turnover by milk intake in postmenopausal women

Increased postmenopausal bone turnover leads to bone loss and fragility fracture risk. In the absence of osteoporosis, risk preventive measures, particularly those modifying nutritional lifestyle, are appropriate. We tested the hypothesis that milk supplementation affects bone turnover related to biochemical markers in a direction that, in the long term, may be expected to reduce postmenopausal bone loss. Thirty healthy postmenopausal women aged 59·3 (sd 3·3) years were enrolled in a prospective crossover trial of 16 weeks. After a 4-week period of adaptation with diet providing 600mg calcium plus 300mg ingested as 250ml semi-skimmed milk, participants were maintained during 6 weeks under the same 600mg calcium diet and randomized to receive either 500ml semi-skimmed milk, thus providing a total of 1200mg calcium, or no milk supplement. In the next 6 weeks they were switched to the alternative regimen. At the end of the each period, i.e. after 4, 10 and 16 weeks, blood and urinary samples were collected. The changes in blood variables between the periods of 6 weeks without and with milk supplementation were: for parathyroid hormone, −3·2pg/ml (P=0·0054); for crosslinked telopeptide of type I collagen, −624pg/ml (P<0·0001); for propeptide of type I procollagen, −5·5ng/ml (P=0·0092); for osteocalcin, −2·8ng/ml (P=0·0014). In conclusion, a 6-week period of milk supplementation induced a decrease in several biochemical variables compatible with diminished bone turnover mediated by reduction in parathyroid hormone secretion. This nutritional approach to postmenopausal alteration in bone metabolism may be a valuable measure in the primary prevention of osteoporosi
