Communication Medium Selection
The same content delivered through the wrong medium loses most of its effect. Bad news in
Slack destroys trust. A complex decision in an email generates confusion. A routine update
in a meeting wastes an hour. Medium selection is not a logistics question — it is a
communication design decision that determines whether the message can land at all.
Your Process
Step 1: Message Goal
What must the receiver do, feel, or understand as a result of this communication? Be
specific. "Understand the situation" is not a goal. "Approve the budget by Friday" is.
"Feel heard about the reorg" is.
Framing check: Confirm the message, the audience, and the goal before continuing. State what you've identified — the actual communication being designed and its key parameters — in one sentence, then use AskUserQuestion:
- Question: "I'm reading this as: [your one-sentence framing of the message, audience, and goal]. Is that right?"
- Header: "Framing"
- Options:
- Yes — proceed — framing is correct
- Adjust — one element is off; user will correct it before you continue
- Reframe — different situation than read; incorporate the correction before proceeding
Step 2: Urgency
How quickly must they act or respond? Hours, days, weeks? Urgency drives the sync vs
async question more than any other factor.
Step 3: Emotional Weight
Is this message carrying emotional content? Difficult news, a sensitive correction, a
celebration, a request that requires trust, a change that affects someone's identity or
security? Emotional weight requires channels that allow nuance and reaction.
Step 4: Complexity
Does this require back-and-forth to resolve, or can it land cleanly in a single read?
Complex decisions with multiple unknowns require synchronous dialogue. Clear information
transfers can be async.
Step 5: Match to Medium
Apply the selection logic:
- Difficult news / sensitive topic → sync verbal (in person or video)
- Complex decision requiring buy-in → meeting with written pre-read
- Simple update, no action required → async written (email or doc)
- Permanent record needed → written
- Emotional connection is the goal → video or in person
- Fast coordination, low stakes → messaging (Slack, etc.)
- Formal commitment → written with signature or named acknowledgment
Step 6: Choose Primary and Secondary Medium
Before narrowing: Show the complete set of candidate media that matched in Step 5 to the user first. Use AskUserQuestion:
- Question: "I've identified these candidate media: [list each matching channel from Step 5]. Before I select the best fit, are there any you'd flag as especially important, or any I've missed?"
- Header: "Prioritise"
- Options:
- Proceed with your selection — the set looks right
- Flag one — user will name a specific channel to include
- Add a missing one — user will describe it
Select the primary channel. If the message needs reinforcement (complex, high-stakes,
or high emotional weight), add a secondary: e.g., meeting followed by written summary.
Human Check-in
Before proceeding, use the AskUserQuestion tool. State your interpretation of the situation in 1–2 sentences — what is being analyzed and what the core question is — then ask:
- Question: "My read: [your 1–2 sentence interpretation]. How do you want to proceed?"
- Header: "Scope"
- Options:
- Full analysis — Complete all steps, reasoning shown throughout
- Key findings only — Bottom-line output, skip step-by-step detail
- Channel recommendation only — Which medium and why, skip the full analysis
- Reframe — The read is off; correct it and the analysis will follow the corrected framing
Proceed based on their selection. If the user reframes, incorporate the correction before running any analysis.
Output Format
Message assessment:
| Dimension | Assessment |
|---|
| Goal | [What must receiver do/feel/understand] |
| Urgency | [Timeline] |
| Emotional weight | [None / Low / Medium / High — why] |
| Complexity | [One-way or requires dialogue] |
Recommended medium: [Primary channel]
Secondary medium (if needed): [Reinforcement channel + why]
Rationale:
[2-3 sentences on why this medium fits this message — and what would go wrong in
the next-most-obvious alternative]
Notes
The most common error is defaulting to async written (Slack, email) for messages with
high emotional weight, because it feels faster and less confrontational. The short-term
comfort always costs more in trust and rework than the difficult conversation would have.
