Unlikely to occur but possible. For example, the project might step back to phase “Design and Implementation of mission 2” once the phase “Operation of mission 1” has been reached, See the Figure below: At the present moment, I think the blog contains most significant subjects.

Most projects have been international European projects. In the daily life, the fourteen phases of the V-model can be compiled and simplified into a model that smoothly fits into the product in question. Consequence to persons or environment.

The hazard can be expected to occur often 4 Occasional Likely to occur several times. Extremely unlikely to occur.

A thorough practical knowledge of the requirements of these standards is essential for the successful certification of railway systems with the appropriate authorities. Does EN cause too much paper and control work?

Then the product is developed, approved and put into operation and finally it is disposed. For such a system, the V-model can be viewed as a life-cycle line, where you step back to a former appropriate phase each time a mission has reached phase “Operation” and the preparation for the next mission starts.

Acceptable with adequate control and with the agreement of the Railway Authority. Maybe, I will start again.
