[BEFORE] I haven’t finished the project yet but I think you could start the visualisation work, what do you think about it?

My recommendation is that you define the project as well as possible before we start.
Believe me if I tell you that we have finished the jobs we started later but with all the information, before those that, in order to run and start as soon as possible, we have had to wait, repeat and charge more to finally deliver the job much later.
