Uma das grandes dificuldades do desenvolvimento de software é adequar, de forma sistemática, os esforços na resolução de problemas e nas melhorias dos processos internos aos objetivos do negócio. O Seis Sigma é uma metodologia estruturada que incrementa a qualidade dos processos e o alinhamento com as estratégias empresariais, proporcionando altos ganhos financeiros para quem o utiliza. Surgido inicialmente na manufatura, o Seis Sigma vem sendo aplicado também noutros setores. No desenvolvimento de software, o seu uso é ainda restrito, mas há indícios de que possa ser utilizado com o mesmo sucesso. O objetivo desta dissertação de mestrado é propor um roteiro específico para a implementação do Seis Sigma nas organizações desenvolvedoras de software. Além do levantamento teórico, foi realizado um estudo de casos múltiplos para analisar as razões da sua adoção, as modalidades de seu uso, os seus benefícios e as suas limitações para os processos de software. Os resultados observados mostram que o Seis Sigma pode ser aplicado total ou parcialmente na melhoria dos processos de software. Além disso, é necessário alguma customização nos processos do Seis Sigma convencional, uma vez que os projetos de melhoria podem estar orientados para novos produtos...

Melhoria de processo de software baseada nos níveis de maturidade fixos da arquitetura estagiada dos modelos SW-CMM e CMMI não atendem à diversidade de contextos e objetivos estratégicos das organizações intensivas em software. Esta pesquisa evoluí a área de melhoria de processo com a utilização da flexibilidade da arquitetura contínua da ISO/IEC 15504 para um melhor alinhamento da melhoria com o contexto e objetivos estratégicos específicos de cada organização, principalmente as micro e pequenas. São identificadas três gerações de arquiteturas de modelos de capacidade de processo (estagiada fixa, contínua fechada e contínua aberta). É proposta uma engenharia de processo, de software e de qualquer outro trabalho humano intensivo em conhecimento, dirigida por perfis de capacidade de processo. É desenvolvida uma abordagem exemplo dessa engenharia com um conjunto de propriedades, um modelo unificado, um ciclo de melhoria e um conjunto de medições, bem como um método para o estabelecimento de perfis de capacidade de processo.

A significant number of studies have documented the use of Data Envelopment Analysis (DEA) for efficiency measurement in the context of electricity distribution, particularly at the level of the distribution utilities. However, their aim has been predominantly descriptive and classificatory, without any attempt to ‘open’ the black box of the transformation process. In contrast, our aim is to explore the potential of DEA to contribute to the design of effective process improvement interventions within a distribution utility. In particular, in this paper, we study an important question within the context of DEA analysis: that is, to investigate whether differences in efficiency can be attributed to a particular managerial programme or design feature. We use two different methodologies to undertake this type of analysis. Firstly, we apply Mann–Whitney rank statistics to the scores obtained from DEA in order to evaluate the statistical significance of the differences observed between an intervention programme and its control group programme. Secondly, we undertake dynamic analysis with the Malmquist Productivity Index in order to study the impact of the introduction of a new technology on a group of units. Our case study focuses on the performance evaluation of medium-voltage power lines belonging to one of the service areas in the Public Electricity Distribution System in Portugal. The results from our case study show that the application of DEA for process improvement interventions has great potential and should be explored in other contexts.

This study has two main objectives. First, the phlebotomy process at the St. Catharines Site of the Niagara Health System is investigated, which starts when an order for a blood test is placed, and ends when the specimen arrives at the lab. The performance measurement is the flow time of the process, which reflects concerns and interests of both the hospital and the patients. Three popular operational methodologies are applied to reduce the flow time and improve the process: DMAIC from Six Sigma, lean principles and simulation modeling. Potential suggestions are provided for the St. Catharines Site, which could result in an average of seven minutes reduction in the flow time. The second objective addresses the fact that these three methodologies have not been combined before in a process improvement effort. A structured framework combining them is developed to benefit future study of phlebotomy and other hospital processes.

peer-reviewed; Software is becoming an increasingly important aspect of medical devices and medical device regulation. Software enables highly complex systems to be built. However, complexity is the enemy of safety, therefore strict adherence to well documented processes is important within the domain of medical device software. Medical devices can only be marketed if compliance and approval from the appropriate regulatory bodies (e.g. the Food and Drug Administration (FDA)) is achieved. This paper outlines the development of a software process improvement (SPI) model specifically for the medical device industry. The paper details how medical device regulations may be satisfied by extending relevant practices from Automotive SPICE.

peer-reviewed; One of the main challenges for ICT organizations is to initiate a well-structured process improvement program. This is particularly the case when adopting a maturity & capability model (MCM) as it brings with it costs associated with internal appraisals, and the realization that in order to achieve a particular maturity level (ML) a number of processes within the Process Reference Model (PRM) will need to be successfully implemented. Some initiatives have been proposed in the last decade, such as the RAPID initiative, but there is still some resistance to adopting MCMs such as CMMI or SPICE (ISO/IEC). This paper will propose the FIRST (Fast Improvement aSsessment sTep) approach, providing a minimum, common-sense set of processes to be appraised during the initial gap analysis which will form the foundation for the design and deployment of an improvement plan, which will be particularly useful for Small-Medium Enterprises (SMEs) and Very Small Entities (VSEs), that are coherent with ISO Management Systems requirements.

peer-reviewed; In this paper we present how functional defect analysis can be applied for software process improvement (SPI) purposes. Software defect data is shown to be one of the most important available management information sources for SPI decisions. Our preliminary analysis with three software companies’ defect data (11653 defects in total) showed that 65% of all the defects are functional defects. To better understand this mass, we have developed a detailed scheme for functional defect classification. Applying our scheme, defects can be classified with accuracy needed to generate practical results. The presented scheme is at initial stages of validation and has been tested with one software company’s defect data consisting of 1740 functional defects. Based on the classification we were able to provide the case organization with practical improvement suggestions

peer-reviewed; Software process improvement initiatives offer many benefits in terms of productivity, cost savings and quality. As part of these initiatives or-ganisations undergo an assessment and then embark on a software process im-provement program to improve their existing processes to meet a desired target. These programs can be improved by the use of process improvement roadmaps that are tailored to the organisation and are usually non-transferrable. Within regulated domains, such as the medical device industry, adherence to interna-tional standards must be achieved before products can be placed on the market. This work proposes the use of software process improvement roadmaps to assist organisations achieve compliance with medical device standards. These pro-posed roadmaps will be generic in nature to meet the requirements of the stand-ard, but will be subsequently tailored to meet the specific requirements of an individual organisation. In this paper we introduce the concept of the software process improvement roadmaps for the implementation of standards and detail a methodology for developing these roadmaps.

peer-reviewed; Although earlier studies revealed much about software process improvement (SPI) in Small- to Medium-sized Enterprises (software SMEs), no earlier research set out to determine the full extent of SPI being implemented in software SMEs. Therefore, this study was designed from the outset to elicit all instances of SPI, which we term SPI events – no matter how small or informal. We make the important new discovery that SMEs initiate a considerable amount of SPI, albeit in varying quantities in different organisations. No earlier study reported that the practice of SPI was so widespread in software SMEs, and this is perhaps related to the extensive scope of the enquiry adopted in this study. Our study also finds that the significant majority of SPI in software SMEs is minor or moderate in nature, sometimes leveraging the human capital via improvements in tacit knowledge. Software development is an intrinsically human intensive activity and it therefore follows that the maximisation of the human capital in an organisation is a source of competitive advantage. However, contemporary process maturity frameworks and quality management standards do not fully exploit the capacity of human capital and may therefore diminish rather than improve the competitive advantage of software SMEs.

peer-reviewed; When it comes to software process improvement (SPI), process engineers look for SPI methods to support process analysis, design, realization, deployment, and management. Although a number of di erent SPI methods and models exist, process engineers tend to view these as too generic, too large, or a poor t for the organization in which SPI is conducted. A strategy to overcome these shortcomings is to concentrate on the artifacts, which precisely de ne the desired outcomes, rather than on speci c methods. In this paper, we present the Artifact-based Software Process Improvement & Management (ArSPI) model that provides a uni ed perspective on SPI and company-wide software process management (SPM), the required key artifacts, and the life cycle models. ArSPI is shown to be of practical support to industry who called for a practical way to de ne the interfaces between SPI projects. This paper concludes with an example of how ArSPI paved the way for several organizations through applying the model in real-world SPI projects.

peer-reviewed; This paper presents a study of the software development processes of very small software companies, with a focus on the company’s Software Process Improvement (SPI) activities. SPI has gained an increasing importance in software engineering domain. However, recent studies show that the obligation and commitment towards SPI especially in small companies is weak and not always taken seriously. This situation is often related to insufficient availability of resources either in term of financial, human and time in this type of companies. Accordingly, this paper explores the current situation in very small companies and gauges their acceptance levels towards SPI actions and the underlying reasons behind this. In this research we carried out a survey which contains open and close ended questions in a series of very small software development companies in Ireland. A quantitative analysis; that use a statistical analysis, and qualitative analysis; that adopt the qualitative content analysis method have been followed throughout this study. The results indicate that the SPI initiatives in very small software development companies are done on a small scale manner, informally and indirectly. In addition, the results also indicate that commitment and involvement of people in these organizations towards SPI is high.

peer-reviewed; This article identifies the effect of team dynamics in the context of software development teams and its impact on software process improvement (SPI) activities in very small companies, in order to understand the relationship between these two variables. Most software development work is done by teams of software engineers working together in a collaborative manner to execute a software development process. Although there is much literature examining software process and how to improve it, less attention has been paid to the issues of team-working and specifically the impact of team dynamics on the software development process. Team dynamics is the term used to define how people work and interact together in teams. Teamwork is more effective with the existence of positive team dynamic, as it encourages a better working environment with satisfied, fulfilled employees who will in turn be more productive. This paper presents the results of a research study of team dynamics in very small software development companies and its impact on the software development process and software process improvement activities.

Nowadays in the software development industry SMEs occupy a considerable percentage of the number of companies generating the 52% of the gross domestic product of the countries and around 72% of the formal employees. However, even when guarantee the software quality is important for SMEs, they have a lack in the implementation of software development formal processes that help them to address this need. This paper shows a comparative between reality and theory focused on the characterization of the needs that SMEs have to face when implementing a software process improvement. The paper is focused on showing the results of analyzing SMEs from Zacatecas Region of Mexico and the results obtained performing a systematic review results and the SME's from Zacatecas Region results are included.

Most of the approaches to improve software process focus on formal process descriptions based on models and standards of best practices. However, the human factor has not been covered, as a result, an important gap arises between processes description and process execution. This gap takes special value in Small and Medium Enterprises (SMEs) because most of them do not have enough resources (time, budget and human) to implement a software process improvement (SPI) without a guarantee of any result due to the investment it represents for them. In order to help SMEs in the implementation of SPI initiatives, this paper presents a set of identified needs that SMEs must face in the implementation of SPI since the human perspective. Moreover, the needs are compared with the results of a local study perform at SMEs of Zacatecas. Besides, the paper includes a proposal focusing on two factors which aims to help them covering the set of needs. Finally, the paper shows the relation of these two factors and the SPI manifesto. © Springer-Verlag Berlin Heidelberg 2014.

Understanding the wide range of outcomes achieved by firms trying to implement TQM and similar process improvement initiatives presents a challenge to management science and organization theory: a few firms reap sustained benefits from their programs, but most efforts fail and are abandoned. A defining feature of such techniques is the reliance on the front-line workforce to do the work of improvement, thus creating the possibility of agency problems; different incentives facing managers and workers. Specifically, successfully improving productivity can lead to lay-offs. The literature provides two opposing theories of how agency interacts with the ability of quality-oriented improvement techniques to dramaticlly increase productivity. The 'Drive Out Fear' school argues that firms must commit to job security, while the 'Drive In Fear' school emphasizes the positive role that insecurity plays in motivating change. In this study a contract theoretic model is developed to analyze the role of agency in process improvement. The main insight of the study is that there are two types of job security, internal and external, that have opposite impacts on the firm's abilty to implement improvement initiatives. The distinction is useful in explaining the results of different case studies and can reconcile the two change theories.; National Science Foundation...

The research focused on determining whether specific process improvement methodologies performed in a Kaizen event could reduce the overall makeready process in a platen die cutting operation. Data was collected and analyzed in order to identify opportunities that would reduce the effort (procedure steps and time) within the makeready procedure. Analysis was conducted on the makeready procedure at a packaging company in Rochester, New York. The researcher worked with the Center for Excellence in Lean Enterprise (CELE) at Rochester Institute of Technology (RIT) in conducting the Kaizen event. An initial analysis with the use of a 5S audit and Individual X-Chart was conducted in order to qualify the types of process improvements that would later be implemented during the Kaizen event. Video recording and spaghetti-mapping diagrams were prepared during the makeready analysis. The information from these two process improvement analysis techniques revealed procedure improvements that were captured during the research. This research revealed opportunities for a Bobst SP-102E platen die cutting machine makeready process by removing the excessive motion to develop a more effective makeready process. With the use of process improvement methodologies in the print manufacturing environment...
