Re: #TheoryOfConstraints being better than #Lean

"TPS does not allow a bottleneck to set the pace of the value stream." blog.gembaacademy.com/2007/04/

From Principles of Product Development Flow by Don Reinertsen (amzn.to/43MW3X0)

"The 100-fold improvement ... was not achieved by finding bottlenecks and adding capacity to the bottlenecks. It was achieved by reducing batch size."

"...the bottlenecks of product development are stochastic bottlenecks, not deterministic ones"

Actionable Agile Metrics For Predictability: Tenth Anniversary Edition leanpub.com/aamfp-10th by Daniel S. Vacanti is the featured book on the Leanpub homepage! leanpub.com #BusinessAndManagement #Agile #LeadershipAgile #AgileBusinessLeadership #Lean #Leadership #books #ebooks

Actionable Agile Metrics for Predictability is a comprehensive guide on how to use flow metrics and analytics to get the predictability your customers crave.

Until now.

"How do you test?"

.. was an interesting question at last night's #pydata Exeter where 2 of the 3 talks were on proof assistants - mine on Lean, another on Isabelle.

The answer is surprising to newcomers.

The only error you can make is in incorrectly specifying the thing you want to prove. You don't make mistakes in the proof itself.

Pretty cool!

After the joys and luxuries of

* Lean's infoview - a continuous evaluation and feedback system for Lean programs

* interactive lisp development with emacs slime-repl

I feel like I'm going back a few centuries with Haskell's edit and then manually compile in a terminal workflow.

As part of our (@sarantja@mastodon.social and yt) research on the usability of interactive theorem provers, we are conducting a study on the usage and state of tools and languages for type-driven development. We are interested in tools that encourage and facilitate type-driven development, especially in cases when they can help us reason about complex problems.

We are hoping to use your responses to identify the characteristic language features and tool interactions that enable type-driven development, with the eventual goals of enhancing them and bringing their benefits to a wider range of programmers.

Please fill in our anonymous, 10-minute survey here: https://tudelft.fra1.qualtrics.com/jfe/form/SV_bIsMxYTKUJkhVuS

You are welcome to participate if you have experience with any type-driven development tool, including dependently-typed languages (e.g., Coq, Lean, Agda), refinement types (e.g., Liquid Haskell), or even other static type systems (e.g., in Rust or Haskell).

P.S. In case you remember signing up for an interview with us in a previous survey and are now wondering whether that study will still go on, the answer is: yes! We’ve had to revise our schedule, but we are still excited to talk to you and will start inviting people for an interview soon.
