One of the eye-opening lines is "TOC is not about de-bottlenecking the Operations but increase the flow thru the bottleneck."
I do think the quote goes a bit too far. It seems more accurate to say "TOC is not only about de-bottlenecking the operations. It is also about increasing the flow through the bottleneck."
If we only think about de-bottlenecking we can get trapped into framing all constraints in terms of the size of the pipe. This leads to thinking that the only way to increase the flow of traffic is by adding lanes to the highway.
If we also think about increasing the flow through existing lanes we may come up with other options. For example, slowing all cars down a bit to eliminate slowing all cars down to stop-and-go.
An example from personal experience: where highways merge there is often a bottleneck. Here in Toronto the 427 (N/S) and QEW (W)/Gardiner Expressway (E) is always a mess. One day I was going southbound on 427 and sailed through the merge at about 80Km/h. This merge was traditionally a 5-10 minute crawl in stop-and-go traffic. I discovered that there was a minor accident a little ways before the merge, in the oncoming lanes of the QEW. This caused the traffic to slow - not stop - and produced significantly higher throughput for everyone.
I'd be interested in what others think, some of whom I've tagged.
