To add to the house analogy... Someone is given a house building estimate of 6-8 months. They they proceed to have business cards printed up, and start ordering materials to be shipped to their house for their new home business, and they slated everything for month 5. And they've already invited their family to come stay with them on month 6 day 2 to stay in the guest bedroom in the basement. ("Yes, I told you I needed a basement last week! Someone on your team was in the room and they didn't say no!"). The house building analogy is pretty far off in many many respects. There are codes and inspections you have to comply with. You want to change X? That will mean new inspections and new codes to follow. There are essentially no codes to follow in software (I wish there were).
