Project evaluation is essential to understand and assess the key aspects of a project that make it either a success or failure. The latter is influenced by a large number of factors, and many times it is hard to measure them objectively. This paper addresses this by introducing a new method for identifying and assessing key project characteristics, which are crucial for a project's success. The method consists of a number of well-defined steps, which are described in detail. The method is applied to two case studies from different application domains and continents. It is concluded that patterns are possible to detect from the data sets. Further, the analysis of the two data sets shows that the proposed method using subjective factors is useful, since it provides an increased understanding, insight and assessment of which project factors might affect project success.  相似文献

One of the goals of collectingproject data during software development and evolution is toassess how well the project did and what should be done to improvein the future. With the wide range of data often collected andthe many complicated relationships between them, this is notalways easy. This paper suggests to use production models (DataEnvelope Analysis) to analyze objective variables and their impacton efficiency. To understand the effect of subjective variables,it is suggested to apply principal component analysis (PCA).Further, we propose to combine the results from the productionmodels and the analysis of the subjective variables. We showcapabilities of production models and illustrate how productionmodels can be combined with other approaches to allow for assessingand hence understanding software project data. The approach isillustrated on a data set consisting of 46 software projectsfrom the NASA-SEL database (NASA-SEL, 1992). The data analyzedis of the type that is commonly found in project databases.  相似文献

Data from 135 teams that have participated in a software project planning exercise are analyzed to determine the relationship between team experience and each teams estimate of total project cost. The analysis shows that cost estimates are dependent upon two kinds of team experience: (1) the average experience for the members of each team and (2) whether or not any members of the team have similar project experience. It is shown that if no members of a planning team have had similar project experience then the estimate of cost is correlated with average team experience, with teams having greater average team experience producing higher total cost estimates. If at least one member of the planning team has had similar project experience then there is a weaker relationship between average team experience and cost, and cost estimates produced by those teams with similar project experience are close to those produced by teams with the greatest average team experience. A qualitative examination of the project plans produced by all teams indicates that the primary reasons that teams with less experience of either type produce lower cost estimates are that they have failed to include some tasks that are included by more experienced teams, and that they have estimated shorter task durations than have the more experienced teams.  相似文献

This paper reports on thedevelopment and validation of an instrument for the collectionof empirical data on the establishment and conduct of softwaremeasurement programs. The instrument is distinguished by a novelemphasis on defining the context in which a software measurementprogram operates. This emphasis is perceived to be the key to1) generating knowledge about measurement programs that can begeneralised to various contexts, and, 2) supporting a contingencyapproach to the conduct of measurement programs. A pilot studyof thirteen measurement programs was carried out to trial theinstrument. Analysis of this data suggests that collecting observationsof software measurement programs with the instrument will leadto more complete knowledge of program success factors that willprovide assistance to practitioners in an area that has provednotoriously difficult.  相似文献

Under the background of information age, the demand of enterprises and individuals for software and related equip- ment is increasing. The software and its affiliated projects have a lot of complexity and uncertainty in the development process. Therefore, risk management for software projects is crucial. This paper firstly expounds the importance of software project risk man- agement, then analyzes the software project risk identification, evaluation and specific countermeasures.  相似文献

Software projects frequently finish late and over budget. Much of the research to date has characterized this problem in terms of inadequate project estimation or incomplete requirements determination. In this study, we concentrate instead on understanding the relationship between project duration and project effort. Over time, a dynamic environment contributes to the expansion of project requirements, thus increasing the scope and effort required to complete the project, irrespective of initial requirements and anticipated project size. Further, frequent delays and interruptions in a project contribute to greater effort each time work is resumed. We develop and empirically evaluate a two-stage model to relate project duration and effort. Our results indicate a significant and positive relationship between project duration and effort, controlling for anticipated project size and other project characteristics. Our model also provides an estimate for the rate of environmental change while projects are in progress. We demonstrate the practical implications of our model by showing how it can be used in conjunction with time boxing techniques and new development methodologies to better scope software projects.  相似文献
