Mainly, the fact that supporting tools are needed and that the use of OCL is tractable for engineers.įor what concerns a full textual first approach to requirements engineering, there is no existing work to our knowledge that is comparable to MESSIR. On the knowledge acquisition results of using UML/OCL modeling notation and tools in requirements engineering education, the students’ know-how results and perceptions we noticed in our experiences are similar to the ones made in the same context and described in. It is worth mentioning that the choice of SWEBOK as a basis for defining the content of a software engineering curriculum has been made. Their internal survey about tools and modeling confirms the choices made which are shared by Messir concerning the models and tool support for SE education. Sequence diagrams are used at design level for modeling objects interactions. Model execution is presented as a key feature for scientific development and the USE/UML SOIL language is used. It is also the chosen class diagram for concepts while the protocol of the system is partly modeled using state machine instead of protocol attributes as in MESSIR. In, the authors present an approach to SE education that supports the education of engineers for mastering modeling and validating models using jointly UML and OCL meta-models for requirements and design. This study is confirmed by another interesting one given in which confirmed the UML models choices, the necessary usage of textual description (i.e., which corresponds to the Messir documentation level) but also the priority management of requirements which is currently not yet supported in Messir. It is shown that change management, traces between requirements design and code, and impact analysis are practiced and required. For functional requirements documentation, it is necessary to support engineers in their current activities which focus on: textual structured requirements (42%) semi-formal use cases (39%), constraints expression (36%) and semi-formal data models (33%). The main result being to contribute to develop the software engineering capabilities of engineers and scientists that feed the job market in industry, research or education.įor what concerns the analysis about software engineering and its current practice in industry and education from a general perspective, the situation depicted in presents a complete survey on requirements engineering practices and standardization needs which presents important principles that we share. Furthermore, the Messir approach solves also some actual problems related to software engineering education by offering a product line framework for setting up or improving courses in computer science curricula.

the state of the art of the “standard” theories, methods and tools, mainly by introducing an improved requirements engineering process, language and verification support based on executable requirements specifications. Messir components represent in themselves some improvements w.r.t.

In the last five years, we have developed a requirements engineering method called Messir with a tool Excalibur and experiments in academia have been made to see how it was solving actual software engineering problems focusing first on requirements engineering education.

Requirements engineering education is an important objective to prepare future engineers to understand those requirements engineering needs and be prepared for practice in a professional setting. Some business or safety critical systems would need an approach allowing for requirements simulation and verification. Some more advanced projects would need more complete requirements documents and would benefit from a description language based on scientific notions allowing for better precision for specific system operations. Some project contexts would need a lightweight activity using structured natural language but still being guided and grounded partly on professional standards. A flexible requirements engineering method should include several levels allowing for more or less completeness and precision.

To be executed in various contexts, there is an important need for flexibility and efficient tool support. Among the software engineering development phases, requirements engineering is the one that has the most impact on project success or failure.
