Contractually obligating pi to be 3, the Earth to be flat, or software features and ship dates to be specified, doesn't make them so.

All you've done is restate the problem as an error on the part of the negotiating process. Not a problem to be dumped on developers.

When you buy something from Amazon Prime and it gets there three weeks later, I hope you are as amused by the "negotiating process."

(Yes, I know, the product you build is different than manufacturing, different than construction, different than paperwork, and every other deliverable.)

[dredmorbius]

Commoditised manufacture, inventory management, and shipping are pretty much precisely the opposite of software development.

Or: your entirely counterfactual counterexample rather neatly proves my point.

[paulddraper]

Software development is commoditised. Or at least a lot is. Static web sites, simple mobiles apps, etc. Some individuals or organizations build them over and over with regularity.
