We have been working for a while on building a product for our clients and now it has reached a stage where we need to decide whether we are ready to go to market with it or not. One of the tasks which would enable us make that decision is to come up with an quality assessment of the product vis-a-vis some of leading products in the market.
What I have already started is (after identifying the target products) is to make a list of functional/non-functional features; on which all products are to be rated. A high level assessement of the quality is also on the list which would mean to drive these products through some of the critical use cases we have and prepare a report.
I would like to know whether anyone has already done this kind of work and what approaches would work best in such a case.
