We were relatively early adopters of Panaya and as such, the product was still maturing. However, this quickly turns into faint criticism, as they quickly responded to every design suggestion we made, and the couple of problems we had with their solution were fixed in a matter of days. In subsequent projects, we have encountered zero technical issues. - One other very minor quibble is that because they are developing the product so rapidly, the extraction and scenario recorders do need to be updated on a regular basis, causing a regular series of transports through the environment. That said, a few transports a month during a project is really the extent of product maintenance required, which compared to the alternatives is trivial.
