Some companies, especially after a few years in operation, start to fixate on "Focus." We need to focus on this market, we need to focus on this product, we need to focus on this feature, and many more examples. It sounds like a good strategy, it sounds like a wise direction. But there are some very dangerous pitfalls to it.
First, focus abuse reduces signals. When people demand focus, they often ask for noise reduction. However, the real world doesn't care much about your ability to process information. Nassim Taleb warned about exactly this in The Black Swan — the information we dismiss as noise is often where the most important signals hide. Harsh, but that's how it works. "You will have to do everything" - Napoleon. In the real world, a lot of things will go wrong, and a lot have to go right before results will manifest. For example, focusing on product development and ignoring operations leads to problems every single time. Not often, but always.
Second, "focus" is often used to promote someone's agenda. I'd be lying if I said this is rare in modern companies. "Let's focus on Sales only — we already have a product." "Let's focus on this product feature — customers can't live without it." "Let's focus on AI because we'll miss the opportunity". Lencioni called this out in The Five Dysfunctions of a Team — internal politics and personal agendas have a remarkable ability to disguise themselves as strategic clarity. The reality is: ask yourself who is demanding focus, and why. A company is a group of people with their own agendas and biases.
Focus is important — however, it must be aligned with strategy and contribute, but not defy culture. That's basically it. Through misuse of focus, you can suppress important information — either by dismissing "noise" or by pushing your own agenda above everything else, even above what actually matters.
I've also noticed that the worse things are at a company, the more people abuse "focus". It's almost like a natural defense mechanism, a cognitive dissonance in action. Narrowing focus becomes a way to avoid confronting uncomfortable truths.
