Dhawan gives a simple decision rule for which channel to use and when to switch: evaluate the message on three factors. Complexity determines richness — a big brainstorm or deliverable warrants a video call with an agenda and recap, while simple items stay in instant messages. Urgency determines the channel's response-time expectation — text for within-the-hour needs, email for 24-hour needs. Frequency determines cadence — recurring items get a standing meeting, and threads that loop without resolving should escalate to a call. Crucially, teams should agree explicit response-time norms per channel so no one feels compelled to answer Slack at midnight.
Origin
Developed from Dhawan's consulting work setting communication norms with client teams, addressing the universal complaints of 'the meeting that should have been an email' and the burnout of ambiguous, always-on messaging.
Core principles
- 01Match the channel to the message using three factors: complexity, urgency, and frequency.
- 02Complex or high-context work belongs on a call; simple items belong in an instant message.
- 03Set explicit response-time expectations per channel to prevent burnout.
- 04When a channel loops without resolving (endless reply-all), escalate to a richer channel.
How to run it
- 1
Judge complexity
If the information is complex — a big brainstorm or deliverable — default to a video call or team meeting with a short pre-agenda and a recap email. If it's simple, keep it to an instant message.
Pro tip Keep complex meetings to 20 minutes instead of 30, or 40 instead of 60, so people get mental-health breaks back.

Judge urgency and set response times
Decide whether you need it in five minutes or five days, and agree per-channel response expectations — e.g. email within 24 hours, Slack same business day, text within the hour.
Pro tip If you Slack at 6PM, expect a reply the next morning, not late that night — protect off-hours.
Watch out Ambiguous urgency creates confusion, burnout, and people texting at midnight when they don't need to.

Judge frequency and set cadence
Decide how often the channel is used and whether the topic needs a standing cadence, like a weekly team video call, with open items parked on that agenda.
Pro tip A leader ran a 9AM and 4PM 10-minute touch base and told the team to bring unanswered questions there, so no one clogged his inbox and he wasn't overwhelmed.
Watch out Avoid letting a five-minute discussion balloon into 30 back-and-forth emails — escalate looping threads to a call.
In the wild
One leader set a 9AM and a 4PM ten-minute Zoom touch base and told the team that any question not answered by email could be brought to him then. Team members stopped fighting to get into his inbox, and he stopped being overwhelmed by rushed asks.
→ Questions got resolved at a predictable time, reducing both wasted effort and inbox overload without anything feeling urgent that wasn't.
Common mistakes
Defaulting to the richest or fastest channel for everything
Rushing everything into an email or Slack, or calling a meeting for simple items, misallocates attention and drives overload; the factors tell you when to go lighter or richer.
Is it for you?
Best for
Any team wanting to set clear communication norms and reduce channel overload and after-hours anxiety.
Not ideal for
Solo operators or relationships with no recurring communication where norms add needless overhead.
From the transcript
“The first principle or factor is complexity of information. The second is the urgency of information. And the third is the frequency of the information.”
