Outsourcing and acquisition models comparison related to IT supplier selection decision analysis

This paper presents a comparison of acquisition models related to decision analysis of IT supplier selection. The main standards are: Capability Maturity Model Integration for Acquisition (CMMI-ACQ), ISO / IEC 12207 Information Technology / Software Life Cycle Processes, IEEE 1062 Recommended Practice for Software Acquisition, the IT Infrastructure Library (ITIL) and the Project Management Body of Knowledge (PMBOK) guide. The objective of this paper is to compare the previous models to find the advantages and disadvantages of them for the future development of a decision model for IT supplier selection

What Can Be Learned from CMMi Failures?

The software crisis has been around since 1968 when NATO first identified the problematic nature of software development. In recognition of the need to manage the process of software development many methodologies have been proposed over the years. A recent contribution to this rich set of rigorous software development methodologies is the Software Engineering Institute\u27s (SEI) Capability Maturity Model Integration (CMMi) methodology. While the minimal previous research on CMMi has extolled it, learning how to implement CMMi successfully requires leaning also from its failures. And yet, despite apparent anecdotes, little is known on this topic possibly because of the reluctance of many companies to wash their dirty linen in public. Based on a set of in-depth interviews accompanied with survey verification, this study examines the assessed effectiveness and efficiency of CMMi as implemented in several projects in a large high tech company in which only low levels of CMMi maturity were reached. In an exploratory manner this study shows the need to differentiate between the quality of the software product developed through CMMi and the quality of the process involved. The study also shows that whether the product is an off the shelf product or a customized one has a direct bearing of the quality of the product developed under CMMi methodology and the process itself. In particular, we discuss why some projects reach only a low maturity level of CMMi even though the organization as a whole might typically reach high maturity levels

An Integrated Six-Sigma and CMMI framework for software process improvement

A process improvement framework such as Capability Maturity Model (CMM) can help develop the maturity of a software development organization over time to achieve predictable and repeatable process performance. However, in the absence of a methodology for process performance measurement, ongoing data-oriented process improvement is hard to institutionalize. For organizations following CMMI, this makes navigating their way through higher-level process management and optimization activities called forth in CMMI Level 4 and Level 5 especially challenging. Altogether, this constitutes a major stumbling block for software organizations striving for higher process maturity as Level 4 and Level 5 Process Areas are essential to institutionalizing process improvement in an organization. Six-Sigma introduces tremendous process measurability through its statistical error-control focus and offers compelling tools and techniques that have strong applicability to software development. Six-Sigma focus on data and metrics married with the CMMI coverage of all aspects of software development through its Process Areas can together provide a powerful process control and improvement framework. A CMMI and Six-Sigma hybrid framework has been presented as a means of achieving software development performance and productivity improvements through statistical error control. Such a hybrid CMMI and Six Sigma framework provides not just greater guidance and rigor in certain areas than CMMI alone but also an inherent flexibility by making an extensive toolset available for use in a wide variety of scenarios. This integrated framework demonstrates that CMMI and Six Sigma are highly complementary and are capable of adding greater value when used in conjunction with each other. This is partly because together they address the weaknesses that may become apparent when either framework is used alone. Six Sigma answers the \u27how\u27 for areas where CMMI only provides the \u27what\u27. Conversely, CMMI provides the overall vision and roadmap that is lacking from individual Six Sigma improvements. It is hoped that this will serve as a blueprint for an implementation of CMMI that makes use of relevant Six Sigma tools and techniques

Effectiveness of information systems outsourcing: An exploratory case study

The objective of this research is to construct an assessment model for measuring the effectiveness of Information Systems (IS) outsourcing. "Lack of expertise" and "cost effectiveness" constitute the major points of motivation for IS outsourcing. Although various decision models and analytical frameworks have been modeled before, the literature is not abundant on a complete qualitative model. In contrast with the decision models which are executed before an outsourcing engagement (a-priori), an effectiveness assessment model will be an a-posteriori guide which will enable the clients to measure their outsourcing performance and re-evaluate their business and management strategies. This paper examines the factors for outsourcing effectiveness through the framework of an exploratory case study for an IS developed by a major Turkish software house for a public organization. © 2012 IADIS
