Abstract
Requirements elicitation is the most critical phase in software requirements engineering. The process is resource intensive, as it concerns with a lot of dedicated stakeholders gathering purposefully to present and stipulate software requirements. The extent of effectiveness of the process is greatly influenced by the suitability of the stakeholders in the process of gathering the requirements. Previous studies indicate that improper stakeholder selection normally lead to unsuccessful requirements elicitation process. Such phenomena would later cause serious impacts to projects such as costly rework, overrun schedule and poor quality software. This study addresses this issue by proposing a model for selecting the suitable stakeholders during requirements elicitation process. The study adopts both the quantitative data collection and analysis. The data gathering was done through survey questionnaire among 300 project managers and analysts. The study employs the Structural Equation Modelling (SEM) to analyse the quantitative data. The results indicate that selecting stakeholders with appropriate characteristics such as stakeholders role, knowledge and communication skills have significant effects on the requirements elicitation phase. The results also reveal that requirements elicitation phase has significant influence on requirements quality. This model is useful for project managers to decide on appropriate stakeholders who are going to be chosen based on their characteristics during requirements elicitation phase.
Highlights
Requirements elicitation is acknowledged as the first stage in Requirements Engineering (RE)
This study has introduced a model for selecting the suitable stakeholders during requirements elicitation process based on stakeholders characteristics such as stakeholders role, knowledge, interest and communication skill
The outcomes of the analyses showed that all independent variables were significant from a statistical point of view, except Stakeholders’ Interest
Summary
Requirements elicitation is acknowledged as the first stage in Requirements Engineering (RE). It involves identifying, gathering and elaborating the requirements of stakeholders for a particular software system, ranging widely from the context of requirements, goals, constraints and features. This process is carried out through investigation and exploration. It is agreed upon by experts that requirements elicitation is a very crucial part of the RE process (Davis et al, 2006) as it has a direct influence on software quality and cost (Cybulski and Sarkar, 2005). It is vital to get the right requirements but at the same time it serves as a difficult part of software development Projects (Aurum and Wohlin, 2006)
