A Framework for Capturing Quality Requirements by Integrating the Requirement Engineering Elements in Agile Software Development Methods

Abstract

The early phase of Agile Software Development (ASD) methods is Requirement Engineering (RE). Quality Requirement (QR) is a type of RE that needs to be captured at the initial development phase to reduce rework, time, and maintenance costs. However, QR is one of the issues mentioned in ASD, namely the need for more capability to elicit, analyze, document, and manage QR. Therefore, this research aims to propose a framework for capturing QR to address QR issues in ASD by integrating RE elements, namely the RE phases, Documentation, Roles, and RE techniques. This research was conducted in four phases: 1) undertaking a theoretical study, 2) conducting an exploratory study to identify the current practices and issues to capture QR in ASD, 3) constructing the framework by using the RE elements, and 4) evaluating the framework by conducting ASD practitioners’ view using questionnaires. The questionnaires were then analyzed using descriptive statistics based on the average mean of each element. The result shows the average mean for all elements (4.25), the average mean of each element for the RE phases (4.36), the documentations (4.11), the roles (4.25), and the RE techniques (4.18). The mean distribution of each element is more than 4 out of 5 indicating that the framework to capture QR is verified. Thus, this framework can be used by ASD practitioners as a guideline to capture QR in ASD methods.
