While it is a good introduction it might be a bit confusing if you are not familiar with multi-factorial designed experiments. You may want to read some of the links below or take advantage of the ability to pause the video to think about what he says or to replay portions you don’t pick up immediately.
He also provides a good overview of 3 basic aims of multivariate experiment (DoE):
screening (to determine which factors have the largest impact on the results that are most important)
optimization (optimize the results)
robustness testing (determine if there are risks in variations to factors)
Normally an experiment will focus on one of these aims. So you don’t know the most important factors you may choose to do a screening experiment to figure out which factors you want to study in detail in an optimization experiment.
imagine various people working within it, somehow swapping out gears and cogs without the clock stopping or slowing down even a little.
This is a fairly good quote on a good management system. Some people might not like the mechanistic model – comparing an organization to a clock, and I agree that isn’t the right model, but even so it is a good quote.
The quote, from a story about the San Antonio Spurs captures what should happen with a good management system. Things just keep running well as inevitable changes take place (and keep getting better in the case of a management system).
A good management system doesn’t rely on heroic efforts to save the day. The organization is designed to success. It is robust. It will succeed with all the variation thrown at it by the outside world. A good management system takes advantage of the contributions people offer, but it is not perform poorly when others are relied on.
A well run organization has graceful degradation (when one component fails or one person is missing the performance doesn’t suffer, bad results are avoided).
An organization succeeds because of the efforts of many great people. But the management system has to be created for an organization to prosper as what we all know will happen, happens: people will leave and need to be replaced. And the people that stay will need to adjust to new conditions inside the organization and in response to external forces. A good management system is constantly improving performance, innovating, increasing the robustness of systems and increasing the capability of people.
The job of managers is to create a robust system that delivers value to customers. A system that fails constantly (fails during the continual variation the system faces) is a failed system. Bad weather is part of the variation airlines face. Any management system has to cope with the variation that it faces. The management system must be designed and managed so that the organization successfully delivers value to customers under the conditions the organization will face.
The air travel system in the USA is a disgrace for so many reasons it is hard to catalogue them all. One, of many, is how fragile the system is; causing massive (nation-wide) customer harm multiple times a year due to weather. Weather is sometimes bad. If your organization fails when there is bad weather, fix that problem (make your system robust in the face of bad weather), because you are not going to be able to fix the weather to let your un-robust system be effective as it is.
Instead airlines only response seems to be to get their friends in government to approve anti-competitive mergers to eliminate competition and allow failed organizations to become even larger and harm even more people. Airlines should design robust systems that work in the environment they will face (which they don’t do now).
Their planes don’t fall out the sky when they face bad weather. The engineers behind designing planes have made them very robust. Pilots have been trained to handle variation they will face. And yes, the system has been designed with adjustments to avoid flying into conditions that are risky.
The safety of the air transportation system is very good. The management of airlines in most every other aspect is pitiful, and has been for decades.
The managers running the airlines have done amazingly bad job of creating robust organizations capable of delivering given the variation they know they will face (weather, mechanical problems, IT problems, etc.) for decades. Poor management is the cause of these failures that result in harm to customers. Weather is not the cause. Poor management, over decades, resulting in incredible fragile systems that constantly punish customers is the responsibility of the airlines. And they have done an incredibly bad job at creating a robust system to deliver value to customers.
