Software development methods and usability: Perspectives from a survey in the software industry in Norway

This paper investigates the relationship between traditional software development methodologies and usability. The point of departure is the assumption that two important disciplines in software development, one of software development methods (SDMs) and one of usability work, are not integrated in industrial software projects. Building on previous research we investigate two questions; (1) Will software companies generally acknowledge the importance of usability, but not prioritise it in industrial projects? and (2) To what degree are software development methods and usability perceived by practitioners as being integrated? To this end a survey in the Norwegian IT industry was conducted. From a sample of 259 companies we received responses from 78 companies. In response to our first research question, our findings show that although there is a positive bias towards usability, the importance of usability testing is perceived to be much less than that of usability requirements. Given the strong time and cost pressures associated with the software industry, we believe that these results highlight that there is a gap between intention and reality. Regarding our second research question our survey revealed that companies perceive usability and software development methods to be integrated. This is in contrast to earlier research, which, somewhat pessimistically, has argued for the existence of two different cultures, one of software development and one of usability. The findings give hope for the future, in particular because the general use of system development methods are pragmatic and adaptable

Transforming failure into success through organisational learning: An analysis of a manufacturing information system

This paper describes the idiosyncracies of a case study company, through highlighting issues and problems experienced during their attempts to evaluate, implement and realise the holistic implications of a manufacturing information system. Although the Information System (IS) was operational for a period of time, it was eventually deemed a failure. The reason for this was that a range of human and organisational factors prevented the organisation from embracing the full impact of the system. The eventual success of their information system was realised through a bespoke implementation, based upon a traditional systems development lifecycle that indirectly addressed learning issues following the earlier failed deployment. The paper highlights key issues relating to business success and failure, and then contrasts them alongside the presented case study. In doing so, the authors conclude by proposing methods through which manufacturing information systems can be transformed for business success. This is described achievable through both a realisation in the positioning of the organisation relative to technology management, and the related mapping of human and technological constructs that support information systems related succes

An open standard for the exchange of information in the Australian timber sector

The purpose of this paper is to describe business-to-business (B2B) communication and the characteristics of an open standard for electronic communication within the Australian timber and wood products industry. Current issues, future goals and strategies for using business-to-business communication will be considered. From the perspective of the Timber industry sector, this study is important because supply chain efficiency is a key component in an organisation's strategy to gain a competitive advantage in the marketplace. Strong improvement in supply chain performance is possible with improved business-to-business communication which is used both for building trust and providing real time marketing data. Traditional methods such as electronic data interchange (EDI) used to facilitate B2B communication have a number of disadvantages, such as high implementation and running costs and a rigid and inflexible messaging standard. Information and communications technologies (ICT) have supported the emergence of web-based EDI which maintains the advantages of the traditional paradigm while negating the disadvantages. This has been further extended by the advent of the Semantic web which rests on the fundamental idea that web resources should be annotated with semantic markup that captures information about their meaning and facilitates meaningful machine-to-machine communication. This paper provides an ontology using OWL (Web Ontology Language) for the Australian Timber sector that can be used in conjunction with semantic web services to provide effective and cheap B2B communications

Enterprise agile transformation model: Barriers, enablers and best practices to implement Agile Methods

Agile Methods currently represent one of the most discussed topics in organisations and teams working with technological products. However, there are still few scientific studies that clearly explain how an organisation can adopt these methods. This thesis has three main objectives, where was developed a study for each: (i) identify in the literature the best practices to implement and manage an agile project portfolio, (ii) identify the barriers and enablers of an Agile Transformation and (iii) expand a theoretical model that allows organisations to carry out an Agile Transformation. The first study used a qualitative approach to carry out a systematic literature review. The second study used a quantitative approach to identify the barriers and enablers. The third study used a qualitative approach to develop the Enterprise Agile Transformation Model. This thesis concluded that, for the implementation and management of an agile portfolio of projects, there are four relevant dimensions to consider. The key four barriers and five enablers for the success of an Agile Transformation were also identified. The Enterprise Agile Transformation Model considers actions to mitigate barriers and enhance the enablers of an Agile Transformation and provides recommendations to increase the agile maturity of organisations. The academic contribution focuses on filling the gap in the scientific literature on Agile Transformations and Agile Project Portfolio Management. For practice, the contribution involves providing a theoretical model with tools, strategies, and recommendations for the implementation of Agile Methods in organisations.Os Métodos Agile representam atualmente um dos temas mais discutidos nas organizações e equipas que trabalham com produtos tecnológicos. No entanto, ainda existe um conjunto reduzido de estudos científicos que expliquem, de uma forma clara, como uma organização pode adotar estes métodos. Esta tese apresenta três objetivos principais, onde foi desenvolvido um estudo para cada um: (i) identificar na literatura as melhores práticas para implementar e gerir um portefólio de projetos agile, (ii) identificar as barreiras e facilitadores de uma Transformação Agile e (iii) expandir um modelo teórico que permita conduzir as organizações a realizar uma Transformação Agile. O primeiro estudo recorreu à abordagem qualitativa para realizar a revisão sistemática da literatura. O segundo estudo utilizou uma abordagem quantitativa para identificar as barreiras e facilitadores. O terceiro estudo utilizou uma abordagem qualitativa para desenvolver o modelo teórico Enterprise Agile Transformation Model. Esta tese concluiu que, para a implementação e gestão de um portefólio de projetos agile, existem quatro dimensões relevantes a considerar. Foram também identificadas quatro barreiras e cinco facilitadores determinantes para o sucesso de uma Transformação Agile. Já o Enterprise Agile Transformation Model, considera ações para mitigar as barreiras e potenciar os facilitadores de uma Transformação Agile e apresenta recomendações para aumentar a maturidade ágil das organizações. A contribuição académica consiste em colmatar a lacuna existente na literatura científica sobre Transformações Agile e gestão de portefólio de projetos agile. Para a prática, a contribuição passa por dar ferramentas, estratégias e recomendações para a implementação de Métodos Agile nas organizações

Combining Process Guidance and Industrial Feedback for Successfully Deploying Big Data Projects

Companies are faced with the challenge of handling increasing amounts of digital data to run or improve their business. Although a large set of technical solutions are available to manage such Big Data, many companies lack the maturity to manage that kind of projects, which results in a high failure rate. This paper aims at providing better process guidance for a successful deployment of Big Data projects. Our approach is based on the combination of a set of methodological bricks documented in the literature from early data mining projects to nowadays. It is complemented by learned lessons from pilots conducted in different areas (IT, health, space, food industry) with a focus on two pilots giving a concrete vision of how to drive the implementation with emphasis on the identification of values, the definition of a relevant strategy, the use of an Agile follow-up and a progressive rise in maturity

Agile Usage: Refining a Theoretical Model

Agile methodologies (AM), which emphasize iterative and incremental development with just-in-time processes and documentation, have been adopted by an increasing number of organisations. Despite this progress there is lack of clarity on their effective use after initial adoption. While there is much research on the use of various agile methods and practices, there is very limited understanding on the critical factors that impact their continued and effective usage. To address this gap, an integrated model called the Agile Usage Model (AUM) was developed, by coalescing insights from organisational level Information Systems implementation, traditional innovation diffusion models, and post-adoptive agile usage. The objective of this study is to use multiple data collection methods to further evaluate and refine the AUM. The final refined conceptual model of Agile Usage is presented along with implications for research and practice

Understanding the structured processes followed by organisations prior to engaging in agile processes: A South African Perspective

There appears to be a lack of knowledge on the phases South African (SA) organisations go through while adopting agile methods. As a means to address this gap, this study uncovered empirical evidence on the phases SA organisations go through whilst adopting agile methods as well as the disparities between agile prescriptions and the way SA organisations actually implement agile methods. The data collected using a case study approach was analysed through the lens of Actor-Network Theory (ANT). The results reveal that there is no structured process for adopting agile methods and organisations go through various phases in their attempts to adopt agile methods. During the various phases, organisations face challenges which are culture as well as people related. Through this study South African practitioners could now be aware that before adopting an agile methodology, there has to be a common understanding of the problems at hand and the envisioned solution. The findings also inform aspiring adopters in South Africa that adoption of the methods does not have to be as prescribed. They are free to adopt only those aspects the organisations need most

An automated framework to support agile adoption coaching

This dissertation aims to assist Agile champions in their organisations with their Agile adoption journey. Such a journey typically starts with identifying the Agile challenges and then determining how to address these challenges in their unique context (Hajjdiab & Taleb, 2011a:9). This study provides a manual together with an automated framework to showcase a list of prioritised Agile challenges and their corresponding possible solutions. Before reaching this automated framework, the research presented a comprehensive list of Agile adoption challenges, possible solutions and a mapping between them. The automated framework, also named Agile Adoption Coach (AAC), is in the form of an online tool: www.agilesense.coza/aac. The critical quantitative contribution to this study was the evaluation of the AAC by Scrum Masters and Agile coaches to determine the acceptability of the tool. The research has shown that there is, on average, an 86% acceptability rating for this tool in South Africa.School of ComputingM. Sc. (Computing

Challenges to transferring and sharing of tacit knowledge within a construction supply chain

Purpose – This paper investigates the potential challenges that hinder the effective transfer and sharing of Tacit Knowledge (Knowledge Communication) within a construction supply chain (CSC). Design/Methodology/Approach – This study identifies six challenges (through literature review) with fifteen positive correlations between them. Quantitative methodology is employed to validate those challenges and correlations between challenges. Firstly, data is collected through semi-structured e-survey questionnaire. Afterwards, a Frequency and Kruskal-Wallis H test is run for initial validation of identified challenges. A correlation analysis is used to highlight the taxonomic relations between those challenges. Finally, the study establishes the rank order of the first and following challenges. Findings – This study highlights that traditional ways of working with construction organisations are the predominant challenge that hinders effective transferring and sharing of Tacit Knowledge. The cause of challenges is the fragmented nature of CSC. Also, it brings out the correlation between those challenges. The study draws the conclusion and recommendation to implement Knowledge Communication (KC) within a CSC. Originality/Value – The study highlights the challenges that hinder KC in a construction process of a CSC. It establishes that the fragmented nature of the construction sector is not the first challenge that hinders implementation of transferring and sharing of Tacit Knowledge but somewhat traditional organisation structures and working processes. This is the first paper that investigates and tests the challenges in four dimensions and establishes the rank order of challenges with crucial distinction in a KC approach within a CSC. Conclusion – This study identifies the rank order of challenges. It also discusses the implementation of KC within a CSC. It reflects the current understanding of KC in the construction sector and pinpoints the contribution of this study in academia and practice.
