Then, when testers create a test case, they link it to the requirement(s) it verifies, again with an appropriate link role - covers or verifies, for example. When requirements engineers create, for example, a functional requirement, they link it to the relevant business case(s) with appropriate link role(s) which describe the nature of the relationship. By creating appropriate links every time an artifact is created, you end up with forensic levels of traceability that can satisfy the most exacting requirements.įor example, suppose the process starts with business cases created in a business case specification document. A comprehensive historical record of testing activity is automatically maintained as well.Ĭreating this robust traceability is like the old joke about eating an elephant one bite at a time. Test cases are linked to requirements in Polarion, which in turn link to MATLAB components, so it is easy to understand the extent of test coverage for all components and what is tested (and how).
Traceability extends onward into testing. Inevitable change during the product lifecycle is easily managed and, most importantly, automatically tracked so that at any given time it is possible to trace who changed what, when, and why. Process is efficiently managed across disciplines and stakeholders by means of workflow, which can be customized to suite the customers exact needs (if these fall outside the parameters of Polarion's robust default workflows for software and systems engineering projects). In the case of MATLAB and Polarion, MATLAB model elements and subsystems can be linked to granular requirements specifications maintained in Polarion's exclusive LiveDoc documents. Polarion's technology is designed from the outset to facilitate wide and deep traceability through every engineering phase. This can be a significant advantage for MATLAB users who design components in companies and industries with stringent compliance mandates. Polarion leverages this capability to enable linking of MATLAB model components to requirements managed with Polarion application lifecycle management products. Experienced MATLAB users know that it has the capability to link model elements and subsystems in diagrams to external requirements specifications maintained in Microsoft Word.
