“Plans are worthless, but planning is everything.”

It’s not the estimate that is valuable. It’s the estimating and seeing how/why the estimate changes over time that is valuable.

Why?

[foxbarrington]

Estimating: similar to planning, thinking through the whole problem and surfacing early anything that seems like not a big deal on the surface, but actually is.

Estimate changes over time: surfaces underlying issues e.g. too many urgent bugs/fires/triage, product changing priority constantly, etc...

Yeah, I don't think "seeing how estimates change over time" is very valuable. The reason that "planning is everything" is that it makes a problem tractable.
