And now for a tough one: do we really do projects this way? With so much paperwork, analysis, planning, designing, revisions, approvals, and acceptances, it must cost a fortune! And it does.
The only problem is, without all that paperwork, analysis, planning, designing, revisions, approvals, and acceptances, it still costs a fortune. And a far bigger one at that.
Remember our house from the start of the chapter? Let's try building it without a methodology.
What kind of house do you need? A house. Do you need one floor, two floors? Well, just start building it, then we'll see where we get. Would you like an entrance from the street, or from the court side? Just put one somewhere, we'll move it later if we need to. Plastic window frames or wooden window frames? Doesn't really matter.
Uh-oh!
With this approach, it's going to be a long journey before this house is built, and I don't want to be there when the bill arrives, and it will probably go down with the first breeze.
