Why did the Tower of Babel Fail?

Now the whole earth used only one language, with few words. On the occasion of a migration from the east, men discovered a plain in the land of Shinar, and settled there. Then they said to one another, “Come, let us make bricks, burning them well.” So they used bricks for stone, and bitumen for mortar. Then they said, “Come, let us build ourselves a city with a tower whose top shall reach the heavens (thus making a name for ourselves), so that we may not be scattered all over the earth.” Then the Lord came down to look at the city and tower which human beings had built. The Lord said, “They are just one people, and they all have the same language. If this is what they can do as a beginning, then nothing that they resolve to do will be impossible for them. Come, let us go down, and there make such a babble of their language that they will not understand one another’s speech.” Thus the Lord dispersed them from there all over the earth, so that they had to stop building the city.

The Tower of Babel project failed because of lack of communication and of its consequent, organization.

“Schedule disaster, functional misfit, and system bugs all arise because the left hand doesn’t know what the right hand is doing.” Teams drift apart in assumptions.
Teams should communicate with one another in as many ways as possible: informally, by regular project meetings with technical briefings, and via a shared formal project workbook. [Or by electronic mail.]
