Product Focused Software Process Improvement: Concepts and Experiences from Industry 总被引:1,自引:0,他引:1
Management problems in the development of software have been addressed over the last years by a strong focus on the improvement of the development processes. Software process improvement (SPI) activities are characterized by an internal focus on a software development department and its procedures. However, the quality of the product is hardly addressed in software process improvement programs. This paper presents the application of a model for product focused SPI (P-SPI) and describes experiences with this model in practice. The main conclusions are that P-SPI puts products to be developed in a central position in improvement programs, results in fulfilling specific quality goals of a company and project, and industrial experiments show interesting benefits. Applying the approach in industrial projects showed that P-SPI is relatively cheap and gives fast results and high benefits. 相似文献

The paper describes results of a longitudinal study of developments in the area of software product and process quality improvement within a Hungarian software company, IQSOFT Ltd. This company has been active in this area since 1993, trying to build, introduce and maintain an efficiently working quality management system which, e.g., fulfils the ISO 9001 requirements, allows steady software process improvement and, at the same time, conforms to company's own needs. Over the last eight years five phases could be distinguished. Each phase is described shortly, following the same structure, namely: basic starting points, key problem areas, literature consulted, activities and design executed, reflections on what happened and why. The lessons resulting from the analysis of this case have been formulated in terms of guidelines. We feel that these are applicable to any low maturity software development organisation embarking on a product or process quality improvement endeavour. These guidelines are developed around a framework containing the basic issues of software production (project management, technical processes and products). The guidelines advocate a careful step-by-step development of definitions, quality characteristics, and metrics related to these objects while at the same time developing and introducing the associated process. 相似文献

This work investigates the modeling of aggregate available bandwidth in multi-sender network applications. Unlike the well-established
client–server model, where there is only one server sending the requested data, the available bandwidth of multiple senders
when combined together does exhibit consistent properties and thus can be modeled and estimated. Through extensive experiments
conducted in the Internet this work proposed to model the aggregate available bandwidth using a normal distribution and then
illustrates its application through a hybrid download-streaming algorithm and a playback-adaptive streaming algorithm for
video delivery under different bandwidth availability scenarios. This new multi-source bandwidth model opens a new way to
provide probabilistic performance guarantee in best-effort networks such as the Internet, and is particularly suitable for
the emerging peer-to-peer applications, where having multiple sources is the norm rather than the exception.
