NIMSAD Framework to Evaluate the Role-based Goal Modelling

Nor Ashila Abdul Rahman, Rohayanti Hassan, Zalmiyah Zakaria, Shahreen Kasim


Requirements analysis is a process of analyzing requirements of various stakeholders that represents a specification of system behaviour that must be stated precisely to proceed to the design phase. It is noted that the current process of requirements analysis is not sufficient to identify and represent the existence of multiple stakeholders which could lead to various conflicts and overlapping requirements. Furthermore, the involvement of various stakeholders normally leads to inconsistencies and misinterpretation of requirements. In this study, the goal modelling representation has been improvised and named as role-based goal modelling. The role-based goal modelling highlights each stakeholder’s role identification in discovering the intentions and requirements of various stakeholders including the integration of data elements in order to determine the dependency of data when dealing with multiple stakeholders. Labour Management System (LMS) owned by Gates IT Solution Sdn Bhd is selected as a case study with participation of different stakeholders. Yet, no standard evaluation method can be used to measure and compare our improved goal modelling with the previous work. Thus, NIMSAD evaluation framework is proposed to compare the effectiveness of our solution with other solutions. In the expected result, this evaluation provides a gap analysis in goal modelling solution. Furthermore, the proposed method could facilitate the process of analyzing and prioritizing requirements from multiple stakeholders in the early stages of the software development process.
