AN EFFECTIVE APPROACH FOR ELICITING REQUIREMENTS AND ENSURING TRACEABILITY: A CASE STUDY OF AUTOMATED TELLER MACHINE

Requirement Elicitation plays a great role in the successful completion of a software project. Elicitation is a productive effort to extricate project-associated information from the stakeholders. To gather complete, concise, and clear requirements, the concept of requirement elicitation allows various analytics and techniques. Requirement elicitation is significant due to the lack of efficiency in accurately articulating their demands towards the intended system. Therefore, requirement engineers realize the need to perform elicitation to ensure that the requirements produced are easily accessible, useable, and applicable according to the client’s demands. A software project can be considered successful if it satisfies all the requirements of the client. In certain situations, changes in requirements from the client side may arise during the development of the intended software. This research focuses on the challenges of this context mentioned as follows-many stakeholders are unable to clearly express their needs toward the intended system and the client-side requirements may change often. In this case, traceability plays a vital role in making the necessary changes in the components of the corresponding requirements. Therefore, the impact of any change can be easily visible & the changes can be applied correspondingly. After all, a project’s success can be achieved by ensuring traceability among the components used in eliciting requirements. So, this research proposes an effective approach for eliciting functional and non-functional requirements and ensuring traceability among the corresponding components used in eliciting requirements. In addition, a tool has been designed to ensure traceability among functional requirements, non-functional requirements, and other corresponding components. If any change request arises to any of the requirements, all the corresponding components associated with that requirement can be traced with the help of this tool. In overall, this proposed approach has been applied successfully to a case study of an Automated Teller Machine using this tool.
