Applying A New Requirement Template for Business, User, and Functional Requirements: A Real Transformation Journey For Business Analysis

Abstract

Accurate and appropriate requirements are fundamental prerequisites for successful software project implementation. There are numerous methods and techniques to elicit and document the software requirements. However, none of them propose an end-to-end solution from business-level requirements to system-level requirements. Therefore, a requirement writing template -requirement cube- was developed in a prominent Islamic Bank in Turkey based on 5W1H questions along with the software. This paper explains the original idea, how the idea was transformed during the application within the organization, and the architecture of the software that was developed. During implementation, the hierarchy of the requirements changed. One more level - acceptance criteria- was added to the business requirement and the business requirement was moved to the software development request module. Besides, another transition level-sub-function-was introduced to integrate enterprise architecture with the requirements. Consequently, the initial theoretical requirement cube structure evolved into an applicable, practical solution for the software requirements.
