Iteration speed is the decisive factor in making a game: a team that rebuilds every day ends up far better than one that rebuilds every week.

  1. Tim Sweeney Founder and CEO of Epic Games We'd constantly be improving the tools and just the iterative process and the speed at which that improves products is the critical element to success in games. The slower the iteration cycle, if you make a build every week and you prove, you go through one iteration every week, you're going to be way way way worse by the end of your project than a game company that makes new stuff every day.

Twenty years of DevOps had one goal, a single feedback loop from writing code to that code in production, and it failed.

  1. Charity Majors Co-founder and CTO of Honeycomb But I also think that in my mind, 20 years of DevOps was really about one thing. Trying to create one feedback loop that connected people writing code to that code in production. And it failed.

The feedback loops a person allows to operate on them shape who they become to an unsettling degree.

Where accurate feedback is scarce, as in investing, progress depends on creating feedback loops

  1. Josh Waitzkin American former chess prodigy I would argue that a lot of what defines the learning curve of someone in a field like investing where accurate feedback loops are few and far between, it’s how creative you are in manifesting them.

On a labs team the feedback loop between making something and knowing whether it is good matters most, and the tightest loop is building for yourself.

  1. Dan Shipper Co-founder and chief executive of Every The biggest thing that that matters on a labs team is making the feedback loop as tight as possible between making something and knowing if it's good. And the tightest feedback loop is making something for yourself.

In game development speed is quality, because the faster you can work the more times you can iterate.

You cannot get real feedback on a new consumer product before shipping the whole thing; feedback starts when somebody spends their own money on it.

  1. Tony Fadell Creator of the iPod and co-creator of the iPhone at Apple And if you're doing a 1.0 and the world hasn't seen you, you're not going to get that from consumers, ever. You have to ship it, and you have to build the entire kind of ecosystem so those consumers see it in the fullness so that when they do the evaluation and they spend their own money, then you're getting real feedback.

Fast feedback is no longer straightforwardly good: agent-speed loops make you rebuild your mental model dozens of times in half an hour.

Feedback should be a daily practice rather than a twice-yearly review, because the team that improves one percent a week overtakes the team that improves one percent a month.

  1. Julie Zhuo Co-founder of Sundial; former vice president of product… But feedback really in my mind ideally should be like a daily practice because the thing that matters for us in the long run as a team is how quickly are we getting better. So a team that just gets 1% better every week compared to a team that gets 1% better a month is even if they start off at a much lower baseline is going to outperform in a very short amount of time the team that doesn't get better.

Rate of iteration separates success from failure: a competitor learning one thing a month will never matter to a company learning one thing a week.

  1. Max Hodak Co-founder and chief executive of Science But the the real theme of the talk is that rate of iteration separates success from failure. And if you can get a fast iteration loop, that really overcomes many other things you're going to run into. And this effect is so severe. I mean, if you can learn one thing every week and there's a competitor that's learning a thing every month, they will they will never matter.
