Requirement engineering evaluation of real time instant messaging using ISO 9126 metrics (integrated RMN signal reader/drafter)

Abstract

Software development that does not have documentation, poses difficulties in modification and maintenance processes. Therefore, the maintenance activity system depends so much on a highly skilled software engineer. As a consequence, project management becomes imbalance especially in workload and responsibility. Moreover, clients are often unaware of the structure development of each software. Client tends to give full trust to the capability of software developer especially when there is no standard communication procedure lined out by developer. Indirectly, it causes the value of activity cost unclear to the customer. Besides, a systematic evaluation upon every system is difficult since software development structure is not concrete and abstract. The DoD-2167A standard was chosen to guide in forming standard documentation in analysis, design and testing. Unified Modeling Language (UML) technique was used to model requirement and software architecture. Object oriented programming was applied in developing the software in easing the maintenance activities. ISO 9126 quality metric is used to evaluate the software system. A signal reader system known as “Virtual Signal Reader/Drafter (VirSiRD)” system has been selected as a foundation to the software development in practicing software engineering tasks.
