Stakeholders' understanding of what is expected of a system evolves with the continuous review and revision of the requirements document.Problems arise when no record is kept of their understanding over long periods of time and when an attempt is made to share that understanding.This paper presents the steps of a Qualitative Systematic Approach to Requirements Analysis (QSARA).The approach has been designed to assist in the analysis of unstructured requirements documents expressed in a combination of natural language text, tables and diagrams.Applying the proposed approach will produce a graphical representation of system features.QSARA 's contributions include assisting stakeholders in capturing, modifying and sharing their understanding of documented requirements.It also facilitates the detection of errors and inter-dependency of features.The paper includes an example from a pilot study of the proposed approach that was conducted to validate its effectiveness.
