A Systematic Review of User-Centered Design Framework Applied to the Redesign of Purchase Order Modules

Usability is a quality attribute that concerns all professionals involved in the software development process. For this reason, several methods have been established to determine if a software product is easy to use, intuitive, understandable, and attractive to users. However, despite the relevance of this software quality attribute, there are still applications with a low level of usability. Enterprise Resource Planning (ERP) software products still provide graphical interfaces that do not consider the context, the conditions of use, and the final objectives of the user. There is evidence that many of these applications, which are widely used in the market, especially the purchase order generation modules, have been designed without following a user-centered design process and without going through an evaluation process. This fact leads many companies to redesign the graphical interfaces that allow user interaction with ERPs. This study reports the results obtained from a systematic literature review (SLR) that aims to identify case studies on which redesign of purchase order modules are reported. The purpose was to identify and analyze the methodologies, tools, and methods most used in the redesign of this type of software application as well as the reasons that lead companies to modify the interfaces. A total of 159 studies were identified, of which 22 were selected as relevant to this review. According to the analysis, frustration and little comfort lead companies to use a User-Centered Design (UCD) framework to redesign the graphical interfaces.
