The biggest paradox in Software Development is its inability to support changes. Do you need to demolish a wall in your house? Not a big deal – just hire a contractor and spend a predictable amount of money and time and the wall will go away. Now, do you need by any chance to introduce some modification in your application (and I hope you don’t)? Well, be prepared to visit the realms of unknownland. Read More

Coherent Sampling

The other day one of our advanced users opened a request in Help Desk about an apparent contradiction.

What does it mean to be an expert?

And I really mean to ask this question. One possible answer, the one that will likely come to mind first, is that an expert is someone who knows how things work, isn’t it? Of course, an expert is someone with a lot of knowledge about a given domain. But what distinguishes a human expert from an expert system? Read More

How is the Testing of PetroVR done? The self-testability of PetroVR

In order to reach the correct coverage, PetroVR testing involves many tasks and activities: mind maps, coverage maps, peer-testing, retrospectives, training meetings and agile practices. However, our testing is also supported by PetroVR itself. Yes, PetroVR is highly self-testable. Read More
