Recently a client ask me how Rapid Lotus Notes Development is. I based my answer from what i previously read from a Notes Programmer David Gurteen and he says that We probably never spent more than 3 days on any one application. This is also similar to me from what i've always do excluding all the rigid testing that an application needs.
This is not always true if the application you're trying to build is so complex.
