The sterile cockpit
No side talk during critical work
Protect defined windows of high-stakes work from all non-essential interruption.
Borrowed from the "sterile cockpit" rule in US aviation, which bans non-essential conversation during critical phases of flight. Read the original source.

Try this first
Protect one window. A specific high-stakes task or time when interruptions wait.
Use it when
Critical work is being derailed by chatter and interruptions.
Skip it when
Use it for critical, attention-heavy moments, not as license to go dark all day. Over-applied it cuts the team off from communication it needs.
How to introduce it
During critical phases of flight, crews limit conversation to the task. Define your team's equivalent windows, the moments that most need full attention, and agree that chatter, messages, and interruptions wait.
How to show up
Define which windows count, agree the norm, and then respect it yourself. Defining them narrowly is the craft, because a rule that covers everything protects nothing.
How long it takes
A short conversation to define the windows and the norm.
What makes it hard
People underrate how much a small interruption costs during focused work, so make the case. The other risk is the windows expanding until they swallow the day, so keep them pinned to critical work.
What it looks like when it's working
The team works undisturbed during critical windows and the work is sharper, and interruptions wait without anyone feeling shut out. Windows that keep getting interrupted mean the norm is not respected. Windows that keep growing mean it is overreaching.
How long until it sticks
Expect a few weeks of use before protecting the critical windows becomes automatic.
How you know it stuck
The team holds interruptions during its high-stakes moments without anyone enforcing it.
The idea behind it
Attention is finite and the highest-stakes moments deserve all of it. Protecting a window is not rudeness, it is how the work gets done right.
Where it comes from
Aviation crew resource management. Protected focus windows for high-stakes work, with a norm that kills the noise. During critical phases, conversation is restricted to the task at hand. Non-essential chatter is banned.
