Why use Scenario TesterTM software?
The single greatest cost of any development project is testing. Making testing more efficient is a vital necessity.
|
In a typical commercial development organization, the cost of providing [the assurance that the program will perform satisfactorily in terms of its functional and nonfunctional specifications within the expected deployment environments] via appropriate debugging, testing, and verification activities can easily range from 50 to 75 percent of the total development cost. (Hailpern and Santhanam, 2002) |
A recent study conducted by the National Institute of Standards and Technology showed the effects of inadequate testing, and the savings if improvements in testing are implemented.

The need for change is huge, but the question is - what changes need to implemented, and how to implement these changes?

The Scenario Tester approach is designed to
| • |
significantly reduce the time and resources needed in each area but also to allow testers to increase test coverage, |
| • |
empower testers to do their job with more efficiency and thoroughness, |
| • |
fit the skill levels of the testers who may be experts in the business, but are not professional coders. |
