I fucking hate estimating time.

I appreciate that agile is better than any planning type before it, but HOLY SHIT is estimating time a fool's game.

I've been at this over a decade now and I'm still like.. 50% accurate at best. The complicated shit is seldom obvious, and usually if I think something will be complicated it ends up being very simple once I dig in.

Aye...

I don't believe that agile is better than any planning system that came before it. We're still producing the same crappy software. And, let's see the first space shuttle launch with software built by a Scrum team---then I might become a believer.

as 3D Realms director George Broussard said about release date of Duke Nukem Forever: "it's done when it's done"

it took 15 years

Rather than estimating what the client wants, give them what he/she is willing to spent.

@platypus look at what Elon Musk does, they work in scrum. Good company did put Tesla in the space.

@stisch unless you are Product Owner your shouldn't estate time. Perfect days at most, but story points are preferred. And in agile approach they explain which User Stories are harder to provide than other, besides that - they are just numbers. Nothing more. Use tshirt coffee sizes if you want.
Agile or not, if you are making crappy software, PO and architect/business analyst should reeducate themselves.

Have you read the Agile Manifesto and Scrum Guide? Have your Product Owner read them? If so, than perhaps your organization should hire an Agile Coach to help? You know, plenty of companies think they do Agile but in fact they do waterfall or management-by-fuckup.

@mt3o 100% this.
Never estimate time. Only estimate complexity.
