This is the first in a series of posts about learnings from the Van of Nerds tour of 11 manufacturing sites in Northern France completed on September 9. First, I describe who we are, why and how we went on this tour. Then, to make this post more than just an introduction, I appended a summary of our observations on automation and people. There is more to come.

“A recent Delphi-type forecast of the future of manufacturing carried out by the International Institution for Production Engineering Research (CIRP) resulted in 94 forecast events on which good consensus was obtained. Of these, 24, or over one-fourth, strongly indicated that the computer-integrated automatic factory would be a full-blown reality well before the end of this century. The three key events which summarize this aspect of that forecast are as follows:

Michel Baudin‘s comments: Thanks to Torbjørn Netland for digging up this gem, which puts the current claims about Industry 4.0 in perspective.
A Delphi-type forecast is based on questionnaires sent to a panel of experts in multiple rounds. Each expert sees the aggregate results of the previous round and modifies answers to arrive at a consensus. In other words, it’s subjective group-think.
Like most of science-fiction, these forecasts both overestimate technology and fail to anticipate its evolution. A “central computer ” was going to do everything. The paper is from 1975, a year after the first personal computer came out, the Altair 8800. At that time, PLCs and minicomputers like DEC’s PDP-11s were already taking over industrial control functions from mainframes.
The author worked for a machine-tool company, Cincinnati-Milacron, and seems to equate manufacturing with metalworking. Machine tools, today, are primarily used in automotive and aerospace; it is only a fraction of manufacturing as a whole.

Until this year, I didn’t pay much attention to Programmable Logic Controllers (PLCs). During Christoph Roser’s van full of nerds tour of Industry 4.0 in Germany last July, I heard about PLCs everywhere and even visited the Siemens plant in Amberg that produces 31% of the world’s PLCs. It was a wake-up call.

The first stop in Christoph Roser‘s tour of Industry 4.0 in Germany last month was a research facility called ARENA2036, attached to the University of Stuttgart. There, the first demonstration we saw was of the Bosch smart floor, and the pictures included here were taken by fellow participants Franck Vermet and Hironori Hibino.

Pick-to-Light directs manual picking by lighting up bins. The Lean literature is mute about it, it’s not in the Industry 4.0 technology stack, and Wikipedia doesn’t have an article about it. Pick-to-Light system suppliers are touting it as part of both Lean and Industry 4.0 but no one else is chiming in. In the field, however, you find it in many factories, where it reduces training time and picking errors, while increasing picker productivity.
Pick-to-Light fits best in usability engineering. It’s neither jidoka nor automation because it just prompts the operator. And it’s not Poka-Yoke because it doesn’t physically prevent mistakes, the way flip-lids can. It looks like an intermediate technology, a stepping stone on the way to full picking automation but is it? It can also be viewed as a move towards using technology to make work easier for people instead of automating it.
