Abstract

The Peruvian government adopted the ISO/IEC 12207 standard and established its mandatory implementation in public entities to improve the quality of the software products. In this context, software requirements validation tasks were introduced to improve the quality of the software product. In this study, the relationship between the improvement of software requirement quality and the software product quality in use was explored and analyzed. Analysis was based on the design of software product quality-in-use and the measure of metrics from ISO/IEC 25010 standard in two software products. The results show that the validation activities introduced in the software requirements stage have a positive relationship with the quality in use of the software products analyzed. In the software studied, it can be said that the improvement of the quality of the requirements has contributed to the improvement of the quality in use of software products. In this case, it has increased time efficiency to complete tasks by 45%, reduced errors for a task by 40%, the number of tasks with errors by 47%, the cost of time to perform tasks by 29%, and unnecessary actions by 53%. In addition, overall satisfaction, user pleasure, information quality, and interfaces quality are the metrics that significantly improve.

信息系统软件开发生命周期中的需求验证：软件使用质量评估

摘要

秘鲁政府采用了ISO/IEC 12207标准，并在公共实体中强制实施，以提高软件产品的质量。在此背景下，引入了软件需求验证任务来提高软件产品的质量。本研究探讨并分析了软件需求质量的提高与软件产品使用质量之间的关系。分析基于软件产品使用质量的设计以及两个软件产品中 ISO/IEC 25010 标准的指标测量。结果表明，在软件需求阶段引入的验证活动与所分析的软件产品的使用质量具有正相关关系。在所研究的软件中，可以说需求质量的提高促进了软件产品使用质量的提高。在这种情况下，完成任务的时间效率提高了 45%，任务错误减少了 40%，出错的任务数量减少了 47%，执行任务的时间成本减少了 29%，并减少了不必要的操作53%。此外，整体满意度、用户满意度、信息质量和界面质量都是显着提高的指标。
