Hi everyone!
This is a good one!
In RAT, you not only can check the quality metrics for your requirements, but also check similar requirements in the same requirement specification document (module, worksheets, etc...), among other features.
However, RAT won't search similar requirements for all requirements in the specification. It will only search for the requirements with Formal Representation Model already built in them. This model will allow RAT to make the comparison between requirements, selecting only the ones close to 100% similarity.
Building the Formal Representation Model in requirements is an automatic process made by RAT after creating and/or editing requirements. This means that the similar requirement search will only take the requirements created and/or edited in RAT. To make this process much faster for the entire specification, the RQS Synchronizer can automatically build the Formal Representation Model for all requirements when it is executed,
On the other hand, this Formal Representation Model in a requirement can be deprecated if the user edits it without RAT. For that, run the RQS Synchronizer again. Nevertheless, the RQS Synchronizer will only build the Formal Representation Model for requirements which does not have already, unless the user has selected the 'Recalculate Formal Representation Model next time' option in the document's properties.
Attached some screenshots.
Cheers!
