PETRA Lite is a tool that will enable the efficient production of inexpensive gui prototypes.

The PETRA Lite product is primarily designed for functional analysts with the following advantages:

A more effective means of harmonizing user expectations with the specifications for the application by introducing a user-interface prototype.

A reduction in the number of errors in the detailed functional specification in the analysis phase by including a user-interface prototype that enables the user to quickly and effectively validate business requirements without having to figure it out a complicated functional specification through the use of diagrams and textual descriptions of use-scenarios.

Improvement of the quality of specifications to ensuing design and implementation phases by making available additional documents generated on a prototype-basis enabling, for instance, a more accurate planning of resources.

Prototyping enables a supplier in a number of days to create and make available to a customer a simulation of the resulting application even before beginning implementation.

The customer specifying the application's business requirements thus has the chance to interactively test out the prototype and effectively harmonise his expectations with the business requirement specifications for developing the application represented by this prototype.

Limitations:

￭ 30 days trial
