Even though object-oriented approach exists for more than 20 years, there are many issues regarding objectoriented system analysis: ambiguity, incompleteness and redundancy in requirements, difficulties with definition and traceability of non-functional requirements, requirements ignorant of business processes that are important for business operations and others. Although software can be engineered using many methodologies, different approaches to the analysis should be considered as they can provide a solution to the known issues. The paper describes the result of the research on object-oriented system analysis in a form of mapping activities offered in advanced software development methods.


System analysis is a crucial and complex step in software engineering process, which affects the overall success of the project and quality of the project outcome. Even though Agile methods have become widely popular, these methods have no structure when it comes to requirements elicitation and specification, which can have impact on whether a project has favourable outcome. Nevertheless, regardless of the chosen approach by industry practitioners, it is important to identify, which activities are currently performed, and analyse the causes and possible issues, which are encountered. The paper presents results from expert survey on the importance of activities related to requirements elicitation, analysis and specification process and the use of tools to support this process. Delphi method, which is used to evaluate the responses, is described. Lists of activities are ranked according to importance and additional information on expert responses is given in the paper. The information can give an insight into the activities and tools that are used in the industry.
