Requirement Model for Water Billing Information System

The purpose of this study is to form a requirement model for Water Billing Information System (BILIS) for the Water Supply Branch (WSB) of Kedah Public Works Department (PWD). Due to recent arising issues and concerns faced by both
consumers and WSB, it is inherent that such disputes are caused by inability to understand consumers’ and users’ needs are, resulting in inadequate system implementation. Further investigation suggests that the problem lies in requirements specification being a harsh reality of the needs. Realizing this fact, a requirement model could assist in minimizing these issues, thus providing an effective payment and verification mechanism. The formation of a requirement model for BILIS was approached using a requirement analysis and capturing methodology that consist of four main phases, namely domain understanding, requirements capturing, classification, and validation. Requirements capturing and classification was done
using Unified Modeling Language (UML) notations that includes use cases, activity diagrams, and class diagrams to depict a conceptual model, sequence diagrams to
represent object behavior and interaction, and additional supplementary specifications. A tool called the Visual Paradigm for UML (VP-UML) was used for validating the syntax of the requirement model while a throw-away prototype with test scripts were used for validating the requirement as a whole. The requirement model provides a referencing point for the development of a water billing system, and can be extended for use in development of other utility billing system in meeting the needs of system users and consumers. This study was concluded by discussing
the findings and constraints as well as limitations arising during the course of producing the model, in addition to recommended future study in this domain.
