It's usually simpler to just send off functional requirements.While there are still plenty companies that do everything-by-UML, practice has shown that formal process can frequently be a hinderance, which is why Agile is preferred these days. Of course, they go so far to abhor every attempt to think up front, so their designs often end up complete disaster by third iteration, but that's another story.Simply put - designer or architect must, regardless of which methodology they choose, be completely familiar with the problems and solutions that are applicable to their particular domain. Then they can choose whichever tools will be best for their team, the budget, the client, and everything else.Quote:what is a good book on uml and what are the tools for design wit it?UML is "language". Learn the symbols, or use a reference. But to use it effectively, you need to understand the domain you will be working in, to know which design to choose.The biggest design flops occur when developers learn UML, then start drawing away, when they do not understand the problem domain they are working in. So their designs end up being very pretty, but completely useless.
