Standardization and Specialization

I am a couple dozen episodes in on Dave Broker's Industrial Revolutions Podcast and cam across this tidbit from chapter 14.

But what Whitworth was most famous for was something called British Standard Whitworth – BSW.

Up until this point, different machine tool makers used different designs for their tools. For the end users – really, anyone involved in industry by this point – it was maddening. If you had a steam engine made by Company X, for example, and one of the screws was damaged, it could only be replaced with a screw provided by Company X or the vendor for Company X. Otherwise the screw wouldn’t fit.

Along with Clement, Roberts, and other Maudslay alumni, Whitworth was a strong proponent for standardization such parts – nuts, bolts, and screws. So, in 1841, he sat down and wrote up what he thought should be the standards. Screw threads should be set at a 55 degree angle with very specific depths and radii. By the 1870s, as the railroads became increasingly frustrated with the different systems being used, they said, “yeah, Whitworth was right.” By the 1890s, everyone was using BSW.

With BSW standardization, a steam engine maker need not produce all of the screws, rivets, fasteners, and other minor parts. Outsourcing these components allowed him to focus on improving the steam engine and the component makers to improve production. Economies of scale in, say, screw manufacturing unleashed by dis-integration would drive costs down dramatically.

I recommend the podcast to fellow history buffs and I am sure I will mine it for future blog posts.

The NFL sends Mediocre Teams to Play in Europe

The NFL schedules a handful of games each season to be played in Europe, London and Munich this year. With plans to expand the program to Africa, Asia, and Australia, The Times of India asks why they disappoint their European fans by not sending "contender teams."

Since the league’s initial foray into Europe in 2007, 42 games have been held on the continent. Yet, only two of these contests featured both teams with winning records - the New York Giants and Green Bay Packers in 2022 and the Kansas City Chiefs and the Miami Dolphins in the 2023 season.

One possibility is that they don't need to - the stadiums sell out anyways. I am reminded of when I lamented to a friend that I have a fondness for the Chicago Cubs but they, at that time, had not won a World Series since before the Depression. His reply was that the fans are so loyal that they do not have to. Why pay for a better team roster when you already sellout the stadium? If you cannot adjust capacity to meet greater demand, adjust demand to meet capacity.

When will RoboTaxis become Profitable?

An interesting article in the WSJ reports on the growing acceptance of autonomous vehicles being used for ride hailing. The dominant platform, Waymo, is currently operating 300 retrofitted Jaguars in San Francisco and 400 in a few other other west coast cities.

It is doubtful that they are profitable yet but there are reasons to believe that the service will achieve economies of scale. Consumer acceptance is growing with Waymo customers being more loyal than Uber or Lyft. As it scales, the trips without paying passengers, now 40% of all trips, should fall. And, while luxurious Jaguars are a nice way to introduce the service, Waymo, plans to introduce less expensive vehicles.
