Abstract

The market for software products offered as a service (SaaS) is growing steadily and has attracted suppliers from different segments of the global IT market. However, the use of the SaaS products brings a range of challenges, both in the organizational, cultural and technological areas. A difficulty that exists today is the lack of methods and models for assessing the quality of these products. This document presents a method to assess the quality of a software product offered as a service, named SaaSQuality. The proposed method has a quality model appropriate to the SaaS context, based on standards and models of software quality (ISO 9126) and models for IT management (ITIL and COBIT). The experimental results obtained through a case study show that the method offers suitable assessment practices for Software as a Service.

Keywords

Abstract

While organizations want to develop software products with reduced cost and flexible scope, stories about the applicability of agile practices to improve project development and performance in the software industry are scarce and focused on specific methodologies such as Scrum and XP. Given these facts, this paper aims to investigate, through practitioners' perceptions of value, which agile practices are being used to improve two performance criteria for software projects-cost and scope. Using a multivariate statistical technique known as Exploratory Factor Analysis (EFA), the results suggest that the use of agile practices can be represented in factors which describe different applications in software development process to improve cost and scope. Also, we conclude that some agile practices should be used together in order to get better efficiency on cost and scope in four development aspects: improving (a) team abilities, (b) management of requirements, (c) quality of the code developed, and (d) delivery of software on-budget and on-time.
