We recently completed a large project for a giant in the color calibration industry. This was a medium-to-large VB6 to Real Studio conversion, and involved designing a few custom user interface components.
This project ran in to the 800-hour range, and the main development phase lasted for about three months. After this time, during the beta phase, specification changes were made and implemented, as well as all the bugs we could fix before the contract period expired. The project has now been turned over to the owner.
