I am currently introducing industry standard usability practices & processes into our software development cycle.

The following prototype phase has been introduced which consists of the following

1.(Parallel Design) Lo-fi Wireframe (3 Versions)

2.Usability Testing on Wireframes

3.Prototype Wireframe based on merged wireframes & usability testing feedback

4.Prototype Usability Testing

5.Prototype Iteration 1

6.Prototype Usability Testing Prototype Wireframe

7.Prototype Iteration 2

This prototype process is for the development of new software products. When would be best to perform an Heuristic Evaluation.

Additionally is this prototype phase ideal? Would it also work for an existing software?

I'm merely after professional opinions and pointers here, Positive or Negative.

I'm entering the world of UX and want to follow the best practices.
