Řízení procesu změny architektury IS / Information system architecture change managent processKuba, Petr January 2007 (has links)
For the runtime phase of automated information system lifecycle is typical a frequent change of system quality requirements. Only systems that can adapt to these requirements are successful in its environment. The system change can be each time of different extensive. If it is necessary for satisfaction of new requirements to add, remove or change some system components and its relations than we talk about system architecture change. This action is so large-scale that it is very risky to implement it without appropriate control and management. This essay addresses these changes and its management. Main phases of the process and its activities are proposed. The suggestion is based on the development process of new systems and available literature from this area. The target of the essay is to offer a certain framework for the change process management. Introduction to iformation system architecture is the first part of the essay. The last part is then concerned in a practical example of information system architecture change and its evaluation.

Educational Manager Perceptions Towards Integrated Management Information System Implementation in YemenAlkaabi, MAHFOOD Hussain 01 January 2018 (has links)
The government of Yemen has been developing government offered services designed to improve the quality of education management. Yemen's managers of education and managers of higher education in the Ministry of Education (MOE) and the Ministry of Higher Education (MOHE) have sought to improve quality of education, reduce costs, and provide timely information for decision-making processes by implementing an integrated management information system (IMIS). The problem was the lack of understanding the barriers that hinder successful IMIS implementation by the MOE and MOHE, and the role that lack of collaboration has played in prior unsuccessful attempts. The purpose of this case study was to identify barriers and success factors related to previous attempts to implement an IMIS in Yemen's MOE and MOHE. Diffusion of innovation (DOI) theory and the technology acceptance model (TAM) provided the conceptual framework. A purposeful sampling was used to select participants for semistructured interviews. The interviews were conducted with 3 ministry personnel, 8 managers, and 4 administrators from various governorates who are currently working or have worked in the Yemen MOE or MOHE. Open coding was used to identify themes and patterns. Themes were related to insufficient human and material resources, lack of understanding and acceptance of IMIS, inadequate IMIS education and training, incompetent program managers, and fear of change. These findings may contribute to positive social change by improving the management of education, thereby the overall quality of education in Yemen. Improving management in education could increase the quality of life by contributing to increase of prosperity through a better-educated society, an active citizenry, and a reduction in the level of societal violence.

Evaluating the feasibility and effectiveness of a web based cardiac rehabilitation programme for those with angina in primary careDevi, R. January 2013 (has links)
In the UK angina affects 2 million people (BHF, 2010b) and unfortunately secondary prevention interventions such as Cardiac Rehabilitation (CR) are not widely available for this population (NACR, 2011). This doctoral research project examined the effectiveness and feasibility of an alternative intervention for this population; CR delivered via the internet. The programme was interactive and comprised personalised goal setting orientated around exercise, diet, emotions, and smoking with support available through an online email link or synchronised chat room. A randomised controlled trial (RCT) and semi-structured interviews were used to evaluate the intervention. Primary care patients with angina were randomised to either an intervention group (n=48) or to a control group that did not receive any intervention other than treatment as usual (n=47). Outcome measures were taken at baseline, 6 week and 6 month follow ups. The primary outcome measure was daily steps (measured objectively using Sensewear Pro 3® accelerometer technology). Secondary outcome measures included daily energy expenditure (EE), daily duration of sedentary activity (DDSA), daily duration of moderate activity (DDMA), daily duration of vigorous activity (DDVA), weight, diastolic blood pressure (DBP), systolic blood pressure (SBP), body fat %, fat intake, fibre intake, anxiety, depression, self-efficacy, and health related quality of life (HRQOL). At the 6 week follow up the intervention group had greater improvements than the control group in daily steps, daily EE, DDSA, DDMA, weight, self-efficacy, emotional quality of life and frequency of angina symptoms. In addition, at the 6 month follow up there were significantly greater improvements in anxiety, and frequency of angina symptoms among the intervention group compared to the control group. Semi-structured interviews were also conducted with a subsample of intervention group participants at the 6 week follow up (n=16). Themes resulting from these interviews indicated a high level of programme acceptability and feasibility; ‘self reported improvements’ and ‘programme facilitators’. However, the theme labelled ‘programme barriers’ illustrated intervention related challenges which should be taken into account when delivering the programme. Overall the study demonstrated that a new web based CR programme was effective at improving lifestyle related cardiac risk factors for a primary care angina population in both the short-term (significantly improved daily steps, DDSA, DDMA, weight, self-efficacy, emotional QOL and frequency of angina) and medium-term (significantly improved anxiety, and frequency of angina). These findings on the whole suggest that the programme could be offered to a primary care angina population who are not routinely included within conventional CR. However, there is a need to consider the factors described to affect engagement of the programme; family and work commitments, bad weather, older age, receiving the programme late in angina diagnosis and levels of self-motivation.

A framework for the introduction of knowledge management within an engineering environmentUbhi, Hardev January 2008 (has links)
This research is based on real issues that have been recognised within the global organisation, Rolls-Royce. The first aim concerned an issue that many companies face, the difficulty that employees face in locating the knowledge and information they require, especially in larger organisations. The developed solution of an Information Map proved to be a success in providing people within the Submarines business with the location of' Configuration Management information. The concept of the Information Map is one that can be adopted by any business as the stages in the tools development have been well documented within Chapters Four, Five and Six. Analysis of the success of the Information Map led to the derivation of 10 lessons learned. These were then verified in a second case study of an intranet development. The second aim of the research was to create a Knowledge Management framework that could be adapted by companies looking to invest in Knowledge Management and provide them with a guide to use. This framework was built from the lessons learned from the Information Map and from other best practice derived from available literature and within Rolls-Royce. The work conducted within the Support business tries to fill in gaps in current research by offering companies a new approach to Knowledge Management, which was based upon the way that industries work today. The creation of the Knowledge Management framework simplifies the work conducted and offers practitioners an easy, high-level approach to the adoption of Knowledge Management by grouping the process into ten steps. This is presented in a fashion that is easy to follow and ultimately offers a guide to make the best use of the resources and budget available to Knowledge Management practitioners. Overall the research addresses the 'real' issues faced by Knowledge Management practitioners. The main contributions to the Knowledge Management domain are the Information Map, action research approach, implementation of Knowledge Management tools for the users needs and a Framework as a guide for industry.

A content based approach for investigating the role and use of email in engineering design projectsWasiak, James Oliver January 2010 (has links)
The use of email as a communication and information sharing medium in large, complex, globally distributed engineering projects is widespread; yet there exists little understanding of the content of the emails exchanged and the implications of this content on the design project, design records and contracts. The importance of these issues is underlined by the fact that email records can now be required as evidence in legal disputes. It follows that the overall aim of this research is to assess the role and use of email in engineering design projects. A state-of-the-art review of literature pertaining to email is reported, along with a review of information and communication processes in engineering design projects. The primary contribution of this thesis is the creation of a content based approach for analysing the role and use of email in engineering design projects. This centres on the development and application of a coding scheme to email text, identifying what subject matter an email relates to, why it was sent, and how its content is expressed. Results are then analysed with respect to the frequencies of each code and other variables, including how coding varies between different senders and throughout the project duration. The second key contribution of this thesis is the analysis of emails and content in an engineering setting by applying the aforementioned approach to two case studies. The major case study concerned a large, complex, globally distributed, multimillion pound systems engineering project, from which 16 000 emails were obtained. It was found that emails are mainly used to transfer information but also to support management functions. Emails facilitate design work but little of this takes place explicitly in the email content. Characteristics of a project affect the subject matter or emails but have little effect on why they are sent. User roles and personal preferences also influence email use. If was found that the purposes for sending emails varied over the duration of a project; it was further determined that these changes could be used to identify project progress and design activity. Implications of the findings are identified in relation to: information management, knowledge management, project management, collaboration and email practice. Significantly, emails do contain potentially important design information and because these often support decisions made elsewhere, emails should be integrated with wider records. More consideration and training should be given to the use of project standards for email use and guidelines for composition. Changes in email use over the project duration could be a potential tool for project managers to identify design progress and possible issues in a project.

An exploratory study of perceived complexity in IT projectsKlotz, David January 2018 (has links)
The considerable failure rate of information technology (IT) projects remains a problem for many organisations and impacts their ability to successfully participate in the digital economy. Previous root cause analysis identified project complexity as one of the key factors in and of IT project failure. The purpose of this research was therefore to critically examine complexity in IT projects. In contrast to earlier positivist research on complexity, this study was built on a critical realist perspective to better understand the underlying structures and mechanisms behind what individuals within IT projects perceive as being "complex".A qualitative research design was chosen with a series of semistructured in-depth interviews with IT project practitioners as the data collection method. The research identified four internal variables (experience, stress, frustration, and motivation) and three external variables (communication, expectations, and support) which interact with perceived complexity. These findings were synthesised into a conceptual model of perceived complexity in IT projects. In addition, the findings indicated that the role of an individual (project sponsor, project manager, project team member) influences perceived complexity. Through the identification of previously hidden mechanisms within IT projects, the study extends the body of knowledge about IT project complexity. In addition, the identified mechanisms were combined with typical situations in IT projects. The outcome, which represents the study's contribution to practice, are practice-orientated guidelines for handling complexity in IT projects which aims to support IT project professionals and organisations to better manage complexity. The study therefore provides valuable contributions to the theory and practice of IT project complexity.
