Education Process
When developing DYNAMICS R4, we did our best to make the S/W operation as simple, intuitive and easy to learn as possible. It is usual that when a specialist leaves the company the use of specialized programs is terminated, or considerable investments are required to train new specialists. In our case it will be easy for a trained specialist to transfer cases and work methods and it will not take much time. The USER’S MANUAL and TUTORIALS with examples will help you quickly cope with our S/W.
Despite the mentioned easy DYNAMICS R4 learning, we recommend our customer to take our education course.
Often the nature of the production process does not allow you to fully understand the software in use. People have to solve everyday problems and master the program together with the everyday workflow, plus good specialists often “sit on several chairs”. On the one hand, this is not bad, the acquired knowledge is well fixed. On the other hand the learning course takes only 5 days and during the course the students deal only with rotor dynamics problems of and get their understanding of the S/W capabilities. This gives the opportunity to both save time in future production tasks and effectively plan future works stages and possible solutions.
It should be mentioned that the regular S/W updating by our experts and its new functionality encourage users to return to us again and be trained at a new level of practical problem solutions.
