Launch on time and on budget

From Getting Real – 37 Signals

Here’s an easy way to launch on time and on budget: keep them fixed. Never throw more time or money at a problem, just scale back the scope.

There’s a myth that goes like this: we can launch on time, on budget, and on scope. It almost never happens and when it does quality often suffers.

If you can’t fit everything in within the time and budget allotted then don’t expand the time and budget. Instead, pull back the scope. There’s always time to add stuff later — later is eternal, now is fleeting.
