The Bottleneck Paradox

Breaking Free from Groupthink

The tendency for us to participate in groupthink can lead to stifling our ability to see things from a different perspective. Then sometimes, I suffer from an inclination to see things from a different perspective first, before seeing the blatantly obvious.

As readers of my blog might have observed in my debunking of the half-glass-full or half-glass-empty debate, this only matters in what is in the glass. You cannot judge my sense of optimism or pessimism from the notion of the glass without examining its contents.

The Contents Matter Most

If the glass contains fine wine, it would likely be half empty because I am enjoying the drink and, by inference, it will remain half full, or full, if I cannot abide the taste, quality, or bouquet of the wine poured in it.

My wine example could spark debate about whether I am proving my point or demonstrating confirmation bias, yet it is in what the glass contains that we can deduce the state. Just as if I knew the glass contained poison, it would remain half full.

This morning, in an engagement with a colleague, he expressed concern that an activity might cause a bottleneck. Here again is the tendency in all definitions to see a bottleneck as a problem.

Reframing the Bottleneck

According to the AI Overview my browser provided, “A bottleneck is a point of congestion in a system—such as production, software, or computing—where a single component's limited capacity restricts the overall speed, throughput, or performance. Similar to the narrow neck of a bottle, it causes delays, reduces efficiency, and creates backups, often requiring the slowest part to be upgraded or optimised to improve the entire process.

Without thinking twice about it, I responded, “Bottlenecks are good; they make the difference between getting the drink in the glass and spilling it everywhere.” Surely, that is a beneficial feature of bottlenecks and the reason why we do have real bottlenecks, as opposed to bottlenecks in application, production, or business processes, on computers, or in networks or traffic.

Those versed in systems thinking might, in this case, distinguish between designed constraints (intentional bottlenecks), which follow my response, and emergent ones (system failures), which engender the broader definition.

Reconsidering Received Wisdom

There might be other situations where the restriction of flow helps direct and concentrate resources to achieve an aim. These are worth considering further.

The other argument might suggest that the definition of bottleneck has evolved well beyond its original meaning. Just remember, when happy and gay literally meant the same thing.

Yet the situations where received wisdom suggests the negative deserve review from another perspective. There is often more to it than what we have been schooled to accept as the only truth.
