968934-1: Demand Control: A Critical Process When Orders Exceed Supply or Orders Are Less Than Planned.

The discussion matches with a lot of my experience in high tech companies.  In those days we did not have all the great analytical tools that now exist, and that many companies have. It was all we could do to keep ERP running.  But the processes are what is required.  The software just makes facts available.

Decisions are not made on facts, though, but on hypotheses which can be tested hopefully with a high enough probability and in a short enough time to make a correction (plan B) if something goes wrong.  Firms need the discipline of reviewing the match of supply and demand and what they are doing about it in a formal way.

I find it interesting that many of the bottom-up processes David discusses are those entrepreneurs are dealing with every day.  The top-down processes, longer term and more strategic, is what we are good at teaching about in business school.

And another comment I found interesting: David’s assertion that often he finds that a company’s decision makers know what needs to be done— they just aren’t doing it!  That to me is the essence of operations management; if we know what to do, why aren’t we doing it?

Brightening the black box of R&D

McKinsey’s take on measuring productivity of R&D.  This is a very contentious area, and many have criticized companies for spending too much or too little on R&D.  It’s largely based on hypotheticals however, because it is hard to guess what a project is going to contribute.  And it’s worse at small innovative enterprises, which are mostly R&D, because there is little info on what the impact of new products will be. The formula would seem to work well at Clayton Christensen’s large stable companies which are simply innovating to please a large group of present and demanding customers, rather than disrupt through spectacular new innovation to gather new customers.  Still, it’s good reading and extends the thinking in this area.

Festo Demonstrates Robots Based on Nature

This article shows that autonomous agents– something only talked about years ago– are becoming a reality. It’s just a matter of time before they take over many routine jobs in factories, and elsewhere.

Gary Knotts’ paper (with Moshe Dror and me) some 20 years ago about autonomous agents and project scheduling was ahead of its time, and many others ahve refined the concepts since then.
