A systematic literature review of use case specifications research

Use cases have been evolved from initial plain, semi-formal textual descriptions to a more formal template structure facilitating automated information extraction in various software development life cycle activities such as requirement documentation, requirement analysis, requirement validation, domain modeling, test case generation, planning and estimation, and maintenance. The issues that remain to be sorted out are (1) the right degree of formalism, (2) the efficient change management, (3) the industrial relevance, and (4) assessment of the quality of the specification. Additionally, its synergy with other software models that are used in the development processes is an issue that needs to be addressed.
