alt Hacker NewsHow do you do either of the following without spending any time at all on estimates?
"Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale."
"At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly."
If I was your colleague, had invested in your company, or was considering giving you money to deliver some product and you refused to tell me when you think it'll be done, it would be the last time any of the above ever happened.
You wouldn't accept that from any service you were attempting to hire, so I don't know why it would be acceptable for software development.
I feel like I've already answered the how question elsewhere. But the short version is a product-driven kanban-ish approach with frequent releases, small units of work, and engaged product management focused on actual real-world goals. This approach originated 25 years ago in Kent Beck's "Extreme Programming". Which did start with estimates, but teams doing well at it quickly realized (via said regular reflection) that they could do without it and still deliver well.
That some random person on the internet who wouldn't have hired me anyhow will now not hire me is a blow I'll have to learn to live with. But I have literal decades of stakeholders happy working this way. One way that happens is that they pick a date and then we built what fits between now and then. So they get the date, but no promises about what will get delivered.
In practice people like this better because beyond a certain very coarse level, estimates are about feelings of engagement and control. What this approach gives them instead is not just feelings, but actual engagement and control. What they get from me is not some unreliable bullshit date, but a commitment to deliver useful things early and often, so that we can together discover something better than their initial visions.
And yes, of course I accept this from people who do work for me. My side hustle is starting a pinball museum. When volunteers take on repairing a just-arrived machine, I never ask them for estimates. I ask them to focus on doing it right. They discover problems, figure out how to fix them, and try it out to see if there are more problems. The work takes as long as it takes. Or I hired a friend to design the logo. I never asked for a date. We iterated on it, discovering an number of things along the way, including through user tests. It took a lot longer than I would have guessed, and that's great, because it turned out better than I could have hoped.
I understand that this is unfamiliar to people, and apparently it's quite upsetting. But I swear this works. There are more things, Horatio.
