Read bead experiment

The "Read bead experiment" was created by Dr. Edward Deming and aim to demonstrate the ineffectiveness (sometimes effectiveness) of the various management methods.
At the end of the experiment, a statistical
graphical tool is used to analyse the experiment's results.
By following this exercise, you will understand that actions taken by the people playing the managers are detrimental to the employees, but after the analyses are shown to have no impact on the efficiency of the process .
The conclusion proposes ways to properly use performance data in a quality environment in order to achieve continual improvement.
The several videos by Fluor Hanford (Steve Prevette) posted below, will help you to understand what is really important in a process.
Meet the company with its "willing workers", quality control personnel, a data recorder, and a foreman. All wish to produce white beads using a 50 holed paddle, but unfortunately there are bad quality red beads.
If you are in a hurry, go directly to part5, minute 2:40 of the video to watch the conclusion of the experiment.

If you don't know Dr. Edward Deming, whatch the video below.

Alexis Monville has published another refreshing video with the same experiment: Expérience des billes rouges (French speaking).

Hi Franck,

it think that this should be a good idea to present this read bead experiment during a CARA Agile session.
What do you think ?

Hi Stephane,

Yes, we can propose this as an expert session to explain system variation.

20 Years of Product Management in 25 Minutes

Mind the Product has been doing an awesome job these years. Follow them, watch their contents, the best Product Management ideas are there. Each time someone new in our PM field ask me about where to start, I have too many things in my mind to propose a simple answer. Each time, I tell me, if I tell them the truth, they may say: this is a too difficult position. So, the best way, may be to show them a funny video with the PM core principles: 20 Years of Product Management in 25 Minutes by Dave Wascha. Enjoy Thanks Dave, Thanks Mind the Product.

Music: From Monoculture to Silots

I recently watched a video titled " What’s a Monoculture? How Artists Are Bigger and Smaller Than Ever " on YouTube, which got me thinking about the shift from music monoculture to silos. This change has significantly impacted how we consume and experience music today. Monoculture and Silos: - Monoculture: This refers to a shared cultural experience where a few artists or pieces of content dominate the global scene. This was more prevalent during the MTV era when music videos and a few popular artists shaped the music landscape. - Silos: In contrast, silos represent the fragmented nature of modern media consumption. Different groups of people are exposed to different content based on their preferences, leading to a more personalized but less universally shared experience. How Did This Happen? Here is a timeline of the last 70 years of modern music to illustrate this shift: Pre-MTV Era (1950s-1980s): - Music was primarily consumed through radio, records, and live...
