At Interim Technologies we highly recommend the approach of developing a prototype before the actual development of the product. Reviewing of the prototype enables users, Promoters, Investors and developers to agree on how an application should look (e.g. screen layouts, reports) and behave (e.g. flow of control, error handling). In some cases, a prototype enables us to confirm that a particular requirement, such as performance, can be met.

Once a prototype is developed we show it to our clients & their customers to determine if it was really what they had in mind. If the prototype does not meet their expectations, it is early enough in the development cycle to redesign and still make the ship date.

A prototype allows one to find out what needs to be changed. By just running a usability study with customers on the prototype's user interface, we can have the answer in time to change the design if necessary before the product is fully developed. Developing a software prototype also leads to a greater understanding of the application requirements, thus improving the system design.
