Profitless Part Proliferation

Profitless Part Proliferation

I wrote a post a little more than five years ago about Variety Reduction Program (VRP), an amazing but little known product design optimization tool.  At the time I referred to VRP as an idea whose “time had not yet come.”  Last week, as I gave a short presentation on VRP, I realized that five … Continue reading

Traditional Lean?

Traditional Lean?

Twice in the last month I’ve heard the phrase “Traditional Lean” used in public presentations.   In neither case did the presenter explain the expression, but one displayed a slide with a Venn diagram showing the overlap between Lean and Six Sigma.  I suppose this means that he defined Traditional Lean as meaning Lean plus something … Continue reading

When I began working in manufacturing back in the pre-Lean era, the quoted lead-time for my company’s products averaged twelve to sixteen weeks. By the 1980’s, however, many customers began to routinely object to our … Continue reading

Ludicrous Speed

Ludicrous Speed

Mel Brooks fans will remember Spaceballs, his jocular jibe at the Star Wars epic. In pursuit of a rebel ship, evil Lord Dark Helmet (Rick Moranis) orders his crew to accelerate their craft beyond the speed of light to “ludicrous speed.” While time travel remains science fiction, our ability to process and transmit data has … Continue reading
