ABSTRACT
Deployment Pipelines are central to a Continuous Delivery approach. They represent an organising principle for the automation of large parts of our development and deliver process. We optimise for fast, clear feedback to help sustain a development team’s ability to make progress with high confidence. Like many ideas that become well know though, they are often misinterpreted.
A Deployment Pipeline is much more than your build script, its more specific than that, It is much more than an automated deployment tool. A Deployment Pipeline is the definitive statement on the releasability of your software.
Dave Farley invented the idea of ‘Deployment Pipelines’ so come along and hear what he has to say on what should, and what should not be in your Deployment Pipeline if you want to create better software faster [...]

Big fan of Dave and his channel should be on any good engineers go to channel.
So am I

Big fan of this guy.
Dave manages to bust another software development myth: "You cannot get both speed and quality!".
My two favorite things. Nice!
Solid
Are there any counterarguments against Dave Farley's ideas presented in this video? Or any limitations to his solutions?
Have a look at some more detailed videos where he also justifies his idea. ua-cam.com/users/ContinuousDelivery
Nope. The limit is physics.
How does this work with the manual test environment. Is there a dedicated tester (person) waiting for something to test?
I've worked several places that wanted to do this, but have never seen it work.
There is only one answer to your problem: Try harder!
Same here. That's why I became a CTO and made it happen, so that I and my team sees this in practice.
I wanted to like this video, but it was sitting at 486 upvotes 😬
Now it's a math coprocessor 😮
Is there a rule in the Universe that states all Tech Conference videos must have horrible audio?
Yup, I agree, I gave up watching the content because the audio is unbearably bad.
Yes, this is a rule. Software people have an ingrained disdain of hardware and signal processing ;)
Could someone help me to understand what you meaning with "build installers" on 21 minute?
As I understand it that is any piece of software that installs what the build stage has produced as output. This could be, e.g., a simple installation script or a typical setup/installer program.
I've described a little better version of this approach here ua-cam.com/video/DR-lxv5UENg/v-deo.html (In Russian). I think Dave's speech is more for big teams, companies and services. If your team or service is small and you have enough autonomy than you can apply even more efficient approach without separate stage for manual testing. But the main Dave's idea is absolutely correct there is no trade off between quality and speed.
In my talk I'm highlighting the problem of splitting the task and the quality of the task. If you are looking on Dave's CD stages and asking the question "What is the slowest stage in this CD cycle?" than you figuring out that Acceptance and Manual Testing are slowest stages, because of iterations between developers and PM/QA on Acceptance and Manual Testing. And this problem we will still have after we've applied all technical and automatic stuff in our CI/CD pipelines. And this problem can be solved.

Good luck reaching a maintainable codebase without proper code reviews on PR-s if you have 1+ developer on a project.
