Everyone thinks, including most programmers, that termination is only associated with terminating the program or system they are working on, and that versions will only exist after the program is finished. But it's not like that, let me explain.
It is true that in the process of creating systems or even a single program, there must be a very clear time and conditions in which it can be terminated, and then deliver it to customers or users. And it is also true that versions must be established to contemplate improvements or even increase the capacities and operations already offered by the programs, but that is not all. It will also be necessary to establish various internal phases as development cut-off points to be able to evaluate the completion status step by step, without waiting to have everything programmed, and versions can also be established for these internal steps.
Well, as I expressed it, there are versions that are not related to any ending.
When buying classes or better when buying the complete course we can be in contact and perhaps I can help you as an advisor, consultant, or collaborator ...
