Our Q/A department will be involved, and we have a process in place that is incorporating testing as part of the deliverable we expect. We are using the Agile (or Scrumm) methodology, and are going through developments in sprints of a few weeks. At the end of each sprint, as per the Scrumm methodolody, we take delivery of an application that is tested and could theorically be shipped as is. This is the nature of the Scrumm process, and a big change of methods that the new Digital Gaming department at Wizards of the Coast has been spear-heading. Radiant Machine is also very involved in that process as in fact, they are the ones that introduced us to this methodology.
We do plan to have alpha, closed beta and open beta tests for the D&DI applications suite when the time is right.
Last, know that I'd prefer to produce a quality product that is not full of bugs.
