 Contribution made to software engineering

The topic of virtual environment and certification will affect the aspect of system integration and testing when relates to the conventional methods of software engineering. The main contribution is the design of a performance-based hardware and application-independent development environment for rapid prototyping of applications.¹⁰ Significant contribution is made to the software engineering of safety critical systems.  There is a increasing number of such application with even more critical requirements to meet. Integration and testing will even be more important as these systems will lead to serious outcomes.

It is noted that many software errors are caused by (1) discrepancies between the documented requirements and requirements for correct functioning of system (2) misunderstanding of software interface and rest of system.³ With the use of virtual environements, a more accurate testing of integration is made with relatively marginal lost of resources, as compared with the event when an actual system crashed.
