Messagingová infrastruktura a produktová analýza trhu / Message infrastructure and market analysisKlimeš, Ivo January 2008 (has links)
There are considered modern messaging architectonical concepts SOA and EDA in this diploma thesis. There are presented the elementary principals of functioning of these paradigms and principals are given into the wider context with the business processes and IT Governance. The aim of this thesis is to compare two preselected software solutions of the operational monitoring. There is always one solution per architectonical style and predefined comparative criteria. This thesis is divided into five consequential parts. The first part is focused on the putting the modern architectures into the historical context. The historical context is the way out for the modern architectonical styles. The part afterwards is closely focused on the concepts of SOA and EDA, and also on the comparison of the mentioned architectonical styles. There are put the concepts into the connection with business processes and maturity models In the next chapters. That all together has a influence on the successful implementation and governance. The chapters continuously flow into the last theoretical part of the thesis, IT Governance. There are described all the elements connected with the successful IT systems operating based on the paradigm SOA or EDA. The context in the practical part is link to the all these previous chapters. There are selected and described two software solutions in the practical part of this thesis. These solutions are then compared by the predefined criteria. The conclusion summarizes all the knowledge acquired during the paradigm comparison and there are also summarized knowledge acquired during the comparison of selected monitoring products.

Modely zlepšování procesů testování softwaru a zajištění kvality / Test process improvement and software quality assurance modelsDošek, Tomáš January 2012 (has links)
Testing often takes between 35 and 50 percent of the total costs of software development projects. Still, the role of testing tends to be underestimated. High costs that are being spent on software testing make a reason for looking for systematical approaches for making the testing processes efficient. Test process improvement models offer such approaches. These models are subject of this thesis. Implementation of process improvement models can be an expensive, long-term activity. Therefore, reasons need to be found, why is important to use such models. Reasons and motivations for using improvement models are demonstrated in the first part of this thesis. It turned out that software testing has, by its historical development, come to the state, when it contains so much theory that companies have a problem absorbing all the knowledge to make testing processes efficient. Therefore, improvement models offer a solution to this problem. This thesis is primarily focused on Test Maturity Model Integration (TMMi), which is being analyzed thoroughly. The work searches for possibilities and limitation of using the model and it summarizes current experiences with the model. Because the TMMi model does not contain a practical assessment method, such method is proposed in this thesis. The assessment method will help organizations using the model. Beside TMMi, the thesis provides an introduction into three other models: Test Process Improvement (TPI), Capability Maturity Model Integration (CMMI) and Critical Testing Processes (CTP). All four models are subject to a comparison based on specified criteria. Results of the comparison are analyzed to identify for which situations individual models suit best. The comparison will help organizations to choose the right model for their needs.

Understanding Process Improvement: Social Psychological Factors Affecting the Use of Project Management PracticesThornley, Russell K. 13 January 2005 (has links) (PDF)
To facilitate a better understanding of the social psychological factors that influence adoption of project management practices, this study draws upon the theory of reasoned action (TRA) and the theory of planned behavior (TPB) from social psychology, and the technology acceptance model (TAM) from information systems research. These models define and relate a number of belief constructs that predict the acceptance of technologies in a variety of settings. In general, the three models each have relatively consistent empirical support, with comparison studies showing mixed support for each of the models being the moderately "better" model. In the current study, the three models are thoroughly integrated using a latent constructs approach and structural equation modeling (SEM) techniques. Overall, constructs from TRA and TAM, but not TPB, predict the use of specific project estimating, plan development, and plan commitment practices defined in the Capability Maturity Models (CMM/I).

軟體專案度量與分析流程規劃~發展QMAP方法林建妤, Lin, Chien Yu Unknown Date (has links)
為提升國內軟體專案生產力和品質,建立度量與分析的機制,本研究參考能力成熟度整合模式(Capability Maturity Model Integration, CMMI)之度量與分析流程領域作為指引,結合GQM (Goal-Question-Metric)及PSM (Practical Software & Systems Measurement)的度量方法論,發展一套提問式驅動度量與分析流程規劃法,稱為QMAP (Questions driven- Measurement & Analysis Process Planning)—運用5W1H (Why, Who, When, What, Where & How) 提問方式,有系統地依據CMMI度量與分析流程的要求,找出軟體專案的成功因素,逐步建立組織內部的度量與分析流程的基準。首先,以某公司之個案情境為例進行背景分析、目標分析和流程分析,接著以使用分析—使用案例及其描述之資訊需求,建議整合運用PSM Insight, MS Project及IBM Rational ClearQuest等工具來支援軟體專案度量與分析流程之自動化。經工具系統之實作展示,再以自我評鑑來檢視QMAP於CMMI度量與分析流程之目標及執行方法的符合程度,而部分未達成的項目則作為未來研究之方向。 / This research proposes a method called QMAP (Questions driven- Measurement and Analysis Process Planning) in order to meet goals and practices in Capability Maturity Model Integration (CMMI). QMAP is about 5W1H questions which begin with why, who, when, what, where and how. Before answering the 5W1H questions, we start with background analysis, goal analysis, and process analysis based on a sample company’s management context. Use Cases are then described as the formal information requirements of the MA process support system. In the implementation, we suggest to integrate some tools, such as MS Project, PSM Insight, and IBM Rational ClearQuest, to facilitate the measurement data collection and analysis activities during the software project development. After illustrating the implementation prototype, a checklist for self-appraisal is presented to identify the compliances of CMMI goals and practices, and the incomplete parts for future research extension.

Identifying Factors Influencing The Acceptance Of Processes: An Empirical Investigation Using The Structural Equation Modeling ApproachDegerli, Mustafa 01 July 2012 (has links) (PDF)
In this research, it was mainly aimed to develop an acceptance model for processes, namely the process acceptance model (PAM). For this purpose, a questionnaire, comprising 3-part and 81-question, was developed to collect quantitative and qualitative data from people having relationships with certain process-focused models and/or standards (CMMI, ISO 15504, ISO 9001, ISO 27001, AQAP-160, AQAP-2110, and/or AS 9100). To revise and refine the questionnaire, expert reviews were ensured, and a pilot study was conducted with 60 usable responses. After reviews, refinements and piloting, the questionnaire was deployed to collect data and in-total 368 usable responses were collected from the people. Here, collected data were screened concerning incorrectly entered data, missing data, outliers and normality, and reliability and validity of the questionnaire were ensured. Partial least squares structural equation modeling (PLS SEM) was applied to develop the PAM. In this context, exploratory and confirmatory factor analyses were applied, and the initial model was estimated and evaluated. The initial model was modified as required by PLS SEM, and confirmatory factor analysis was repeated, and the modified final model was estimated and evaluated. Consequently, the PAM, with 18 factors and their statistically significant relationships, was developed. Furthermore, descriptive statistics and t-tests were applied to discover some interesting, meaningful, and important points to be taken into account regarding the acceptance of processes. Moreover, collected quantitative data were analyzed, and three additional factors were discovered regarding the acceptance of processes. Besides, a checklist to test and/or promote the acceptance of processes was established.

軟體業導入品質管理機制影響之分析–以一軟體公司導入CMMI的經驗為例侯志霖 Unknown Date (has links)
軟體產業向來都是腦力密集產業,面對全球化的趨勢,其競爭層次早已不再侷限於國內,而是提升至跨國與跨區域的領域。因此唯有強化競爭力才得以屹立於產業中。
卡內基美隆大學的軟體工學院(Software Engineer Institute, SEI)制定之能力成熟度整合模型(Capability Maturity Model Integration, CMMI),已成為國際軟體工程中廣泛認同的標準。行政院制定的六年國家展計畫(2002–2008),其中數位台灣(e–Taiwan)專案中政府更擬定推動民間業者CMMI的計畫,以提升國內軟體開發的素質與強化國際競爭力。
CMMI的導入,無疑是希望從組織面、成本面、品質面等面向全面提升軟體的品質。然而在眾多的導入案例中,學術界對於台灣的軟體企業導入CMMI產生之影響所進行的研究論文相對匱乏。而且國內的資訊軟體業者普遍為中小型機構,是否可以獲得預期的效益也未可知,然在導入的過程卻必須先面臨接踵而來的衝擊。
本文針對已經有成功導入經驗的業者進行研究,藉由研究執行CMMI所衍生的負面衝擊並釐清這些衝擊產生的原因,以協助企業在開始執行之前便能了解其影響,以及相關衝擊產生之原因。讓企業經營階層在執行導入CMMI決策時有更為完整的參考依據,以降低導入CMMI時所衍生出的負面衝擊,進而提升效益。

The relationship between process maturity models and the use and effectiveness of systems development methodologiesVan Rensburg, Christoffel Wilhelmus Janse January 2012 (has links)
The need for information systems has increased to a point where virtually all business environments require some sort of software to aid in its daily operations. This study will address the need for quality information systems by examining techniques which can potentially aid in producing consistent high-quality information systems. Two techniques in particular, namely Process Maturity Models (PMMs) and Systems Development Methodologies (SDMs) are examined.
Process Maturity Models such as the Capability Maturity Model Integration (CMMI) as well as the ISO-9000 standards aid in standardising and improving an organisation’s information systems development processes. These Process Maturity Models often require either the use of certain Systems Development Methodologies or at the very least techniques used within some Systems Development Methodologies. Systems Development Methodologies refer to a set of development processes, tools, techniques etc. which can be used during software development to standardise the entire development process by offering the use of modelling techniques, tools to analyse requirements, illustration of processes etc. These techniques differ from one Systems Development Methodology to the next.
This study aims to identify the relationship between Process Maturity Models and Systems Development Methodologies. During the research process a questionnaire was sent out to people within the information technology business environment. The questionnaire contained questions used to determine and measure the usage of Systems Development Methodologies and how projects were affected. The questionnaire was also used to do an informal assessment of each respondent’s Capability Maturity Model level. Furthermore the data retrieved was statistically analysed and the results were interpreted.
The results indicate that a relationship exists between the use of SDMs and the success of the respondent’s development processes and developed products. A total of 73% of respondents indicated that they do use SDMs to some extent, the most common being the Systems Development Lifecycle (SDLC). The majority of organizations implementing SDMs have been doing so for three years or more. Results also show that most of the respondents are not certified in some formal Process Maturity Model; however, they do implement some of the processes required by models such as the CMMI. An informal assessment performed indicated that 65% of respondents can be grouped into a perceived CMMI level 2 category. Project outcome was measured and the relationship between PMM implementation as well as SDM use was measured. Results show no statistical evidence which indicates that an organisation’s perceived CMMI level is influenced by SDM use, both vertically and horizontally. Results do, however, indicate that organizations which have been implementing SDMs for a longer period of time are more likely to apply CMMI level 4 activities. Results also indicate that the horizontal use (number of projects/people which implement SDM knowledge) of SDMs have a significant effect on the development process- and the developed product success. Lastly the results indicated that organizations which satisfy more of the CMMI’s level 4 activities experience a higher quality development process which leads to a more successful development process. / Thesis (MSc (Computer Science))--North-West University, Potchefstroom Campus, 2013.
