Let's say, I have a project with well fixed deadlines, and a pretty good specification. Every specification needs additional discussion, with taking in consideration the client's requirements (I mean, this additional specifications won't be essential, but anyhow useful and necessary). But the client is too busy to answer to the mails, phone calls.
The project is ordered by the client, but its success depends on the development team, because it is made for an event with fixed date.
What is the best solution in this case?
- Take decisions without the client's agreement: advantage: the project can be delivered in time; disadvantage: double development time, if the client wants other solution, or
- Wait until the client answers: it can throw the finish time after the deadline, which isn't a good "advertisement" for the developer company?
