Why Estimations Are Irrelevant

The TLDR Product newsletter is putting out a post about why estimations are irrelevant. The author is Dan Pereira, who writes for TLDR Product, and the piece is available on his Substack at https://dpereira.substack.com/p/why-estimations-are-irrelevant?utm_source=tldrproduct.

The post argues that estimations don't matter much in the way most people think they do. It's a short piece from a newsletter that covers product stuff for people who build things. TLDR Product is run by Kristen Berman, and Dan Pereira writes for them.

The post is brief. It doesn't go into deep detail about what estimations are, where they fail, or what to do instead. It just says they're irrelevant and that's about it.

TLDR Product covers product management, design, and the work of building software. They write for PMs, designers, and engineers who want to get stuff done without the fluff. The newsletter is a daily thing, so people read it to stay sharp on product thinking.

If you're someone who gets stuck trying to guess how long something will take, this might be a nudge to let go of the estimate and just start. The post doesn't tell you what to do instead — it just says the estimate isn't the answer.

Why this matters for us: When you're building something for la comunidad — a side hustle, a community app, a tool your tios actually use — every hour you spend guessing instead of doing is an hour you're not building what matters.
