Requirement Engineering & SysML

Requirement Engineering is essential for developing complex products. It allows to gain a general overview of the product and to follow the entire development continuously during each single stage. Model Based
System Engineering and quality certifications such as ISO26262 and CMMI are greatly accomplished by this approach.

Requirements collection is the most important and awkward activity for a new product concept as a strong collaboration is required among several different technical teams. The Stakeholders definition
follows: a group of persons able to influencing an activity by its conduct. Among possible profiles arising in the product concept the followings are always present:

  • all persons interested on the new product/system creation;
  • the Customer and the final users: persons knowing deeply what the product/system will be used for, but without an appropriate technical knowledge concerning single technical aspects and sub-components;
  • technical personnel and developers: persons having a deep expertise in their specific competence field, but without a global overview; they do not know what the impact is of their work on the work
    of colleagues operating in different fields.

The organic and structured handling of design requirements allows to avoid misunderstanding or lack of communication among different design teams, minimizing time losses and implementation costs. Metalanguages
such as SysML and UML are helpful in this sense, creating a unique development environment understandable to all teams no matter which their technical competence is and avoiding misunderstanding due to natural language usage.
