I think your last sentence is an example of semantic drift.

I don't think a single compile cycle per half day meets most people's definition of a sprint...

>I don't think a single compile cycle per half day

Hm... I read this quite differently than you do. Not compile cycles, but actual test-driven product iterations.

Do you have more solid sources than I do?

Let's check those sources.

1) "A brief history of agile methods" asserts:

1958 — Project Mercury (NASA) software development, ran with half-day iterations.

The only thing that looks like it could be intended as evidence for that assertion is the Larman and Basili article.

2) "Rockets before Rovers" asserts:

Project Mercury did half-day iterations with test first development!

The only thing that looks like it could be intended as evidence for that assertion is the Larman and Basili article.

3) So there only seems to be one source — Larman and Basili "Iterative and Incremental Development: A Brief History" — which asserts:

"Project Mercury ran with very short (half-day) iterations that were time boxed." page 2

Where's the evidence for that assertion?

afaict the Larman and Basili article does not provide a source as evidence for that assertion?

So we're left with nothing.
