Generally, software testing would first see if the software worked as designed. Then, the actual software users would test the software in real-world scenarios. It’s no longer feasible to separate the testing, it’s too costly and time consuming. 

Prolifics’ extends functional testing to include the desired business outcomes, or business assurance. This means you can expect software testing to check for business outcomes early in the testing process, as well as into real-world use.

The benefits to you are faster testing, better quality software, reduced costs and the assurance throughout the testing process that the software will deliver as intended.
