HYBRID MODEL

Hybrid model: 

It is combination of two or more software models.


Hybrid of v model and prototype model :



  1. In the first stage CRS is given to both developers and test engineer. The developer convert CRS to SRS and prototype while the test engineer review CRS and write acceptance TP and TC. Mistakes in the CRS are fix by developers and again convert into SRS and prototype.
  2. The developer send SRS and prototype to the testing team they review SRS right system TP,TC and also do prototype testing. Mistakes in the SRS and defect in the prototype are fixed by the developer and verified by the test engineer.
  3. The test engineer send the prototype to the customers for review. The customers ask for the changes if any e to the developers if they are satisfied to the prototype they give an approval. 
  4. The developer convert SRS to hld while the test engineer review HLD and write integration TP,TC mistakes in the HLD affix by the developers and again convert into LLD.
  5. Developers convert LLD into source code the test engineer review LLD, the write functional TP,TC. Mistake in the LLD affixed by the developers again convert into source code.
  6. The developers dumped the source code inside the repository and do unit testing (WBT). 
  7. The test engineer on the software do FT, IT, ST, AT and release the software to the customers.


Note: advantages disadvantages and applications for this model are same as v model and prototype model
