4.3 Communication Planning: Who Hears What, When

4.3 Communication Planning: Who Hears What, When
Chapter 4.3 Part of 4.0 Team Management

Communication Planning

“Communicate more” is not a plan, and it isn’t even usually the fix. Projects fail from information reaching the wrong people at the wrong time in the wrong form — which is a design problem, and design problems have solutions.

New to this? This is the last of three sections in 4.0 Team Management, and it takes its input from 4.2 Stakeholder Management — you can’t decide who hears what until you know who they are. Terms are defined at the bottom and in the glossary.

In short

  • A communication plan says who hears what, how often, through which channel, from whom. Four columns and a page.
  • Tailor the message to what each audience has to do with it — not to their seniority.
  • Deciding who does not need to hear something is half the value.
  • Automate the routine flow so human attention goes to interpretation and decisions.

Communication is a system, not a virtue

The instinct when coordination goes wrong is to add a meeting. Sometimes that’s right. Usually it addresses the symptom — someone didn’t know something — without touching the cause, which is that nobody decided in advance whose job it was to tell them.

A plan replaces that assumption with a small number of explicit decisions. It takes an hour to write and it removes the entire category of failure that begins “I thought you were telling them.”

The same fact is three different messages

One project fact turned into three different messages, and one deliberate silence A single fact — integration testing will finish five days late because the vendor review overran — branches to three audiences. The sponsor gets one line in Friday's card: the launch date still holds, three of eight buffer days used, no decision needed. The team gets a message on the task today: the test window moves to 12 to 19 May and Sam's automation run shifts with it. Support and end users get nothing yet, because nothing they were told has changed; if the buffer runs out they hear it the day it is known. WHAT HAPPENED Integration testing will finish 5 days late. The vendor review overran. THE SPONSOR — one line, in Friday’s card “Launch date still holds. We’ve used 3 of our 8 days of buffer on the vendor review. No decision needed from you this week.” They need to know whether to worry. That is the whole message. THE TEAM — on the task, today “Vendor review landed Thursday. Test window moves to 12–19 May. Sam — your automation run shifts with it. Everything else is unchanged.” They need to know what to do differently on Monday. SUPPORT AND END USERS — nothing, yet No message. Nothing they were told has changed. If the buffer runs out, they hear it the day we know — not the week before launch, and not through the grapevine. Same fact, three different messages, and one deliberate silence. A communication plan is mostly a set of decisions about who does not need to hear each thing — that is what keeps the ones who do paying attention.
Note that none of the three messages is a summary of the others. Each is built backwards from a different question: should I worry, what do I do on Monday, and does this change anything for me.

The bottom panel is the one people find uncomfortable, and it’s the most important. Telling everyone everything is not transparency — it is offloading the filtering work onto the reader, and the predictable result is that they stop reading. Attention spent on updates that don’t concern you is attention unavailable when one does.

Building the plan

One table, one page. If it needs more, the project has too many independent interfaces and the fix is structural rather than editorial.

What Who When Where Owner
Status & exceptions Sponsor Weekly, Friday Card in the project channel PM
What changed today The team Continuous On the task itself Whoever changed it
Blockers & decisions The team Daily, 10 min Standing call PM
Working demo Users, support Fortnightly 30-minute session Team lead
Milestone reached Everyone On the event Automatic notification
Date at risk Sponsor first Same day, always Direct message, then card PM

Three things that row set gets right and most plans get wrong. The owner column is filled in with names, so nothing depends on collective memory. The last row exists at all — most plans cover routine reporting and say nothing about the one communication that matters most. And several rows are continuous or automatic rather than scheduled, which is where a tool should be doing the work.

Choosing a channel

Channels differ along two axes that actually matter: whether they demand attention now, and whether the message survives being missed.

Immediate and permanent

A comment on the task; a message in the project channel. The default for project communication: it interrupts appropriately and it is still there in month five when someone asks why.

Immediate and ephemeral

A call, a corridor conversation. Fastest way to resolve something genuinely ambiguous — and the decision then has to be written somewhere, or it didn’t happen.

Deferred and permanent

The Wiki, the plan, the scope document. For things people need to look up rather than be told. If you find yourself re-explaining something, it belongs here.

Email

Sits awkwardly across all four and is read by nobody with a full inbox. Reserve it for people outside your tooling and for things that need a formal record.

The most common channel error is putting a decision in an ephemeral place. Six weeks later there is no record, two people remember it differently, and both are being honest.

Push what changes, pull what persists

A simple discipline that removes a surprising amount of noise:

  • Push events — something changed, something is blocked, a decision is needed. These have a time value and expire.
  • Pull states — what the current plan is, who owns what, what the scope says. These should live somewhere anyone can look, not be pushed repeatedly to people who might need them.

Get this backwards and you produce the two classic failures at once: weekly reports full of unchanged information nobody reads, and genuine changes buried inside them.

Meetings that earn their cost

A meeting is the most expensive channel available — its cost is the number of attendees multiplied by its length, and it’s paid whether or not anything happens. It’s worth it for exactly three things: deciding something that needs several people, resolving a disagreement, and building the shared understanding that makes the rest of the week’s async communication work.

It is not worth it for transferring status, which a tool does better and asynchronously. If your status meeting consists of everyone reading out what a board already shows, you have a meeting compensating for a system nobody trusts — and the fix is to make the board trustworthy.

The habits that carry it

  • Be boringly regular. Every Friday, including the Fridays with nothing to report. Predictability is most of what people mean by trust.
  • Lead with the bad news. Burying a slip in paragraph four teaches people to read you sceptically forever.
  • Say what you don’t know. “We don’t yet know if this affects the date; I’ll know Thursday” is a complete and useful update.
  • Close the loop. When someone raises something, tell them what happened to it — including when the answer was no.
  • Write for the person who wasn’t there. Most of your communication will be read by someone catching up. A message that assumes yesterday’s context excludes them.

How this looks in AB

In AB Projects, the communication plan stops being a document people forget and becomes the way the work runs.

The plan itself lives as a pinned page in the project Wiki — the who / what / when / where table above. But most of the day-to-day flow happens without anyone remembering to do it: Adaptive Cards posted to the linked Teams or Slack channel announce status changes the moment they happen, complete with the task ID and a one-tap deep link, so the “milestone reached” and “what changed today” rows largely take care of themselves.

For everything needing a human nudge, mentions on tasks reach the right person on the right thread rather than broadcasting to a channel. AI assistants connected through the MCP server can post scheduled summaries too, and they carry a clear robot signature so attribution stays unambiguous — which matters, because an update whose author is unclear is an update nobody acts on.

The change-history tab on every task records who said what and when. That turns “was it communicated?” from a matter of recollection into something with an answer — useful in a retrospective, and considerably more useful in the meeting where two people remember a decision differently.

Terms used on this page

Communication plan
An agreement about who receives what information, how often, through which channel and from whom. One page, or it won’t be followed. More →
Asynchronous communication
Messages that don’t require both parties at once — comments, documents, recorded updates. Cheaper in attention and better for anyone in another timezone. More →
Information radiator
A always-visible display of project state — a board, a dashboard — that people pull from rather than being told. Replaces most status reporting. More →
Escalation path
The agreed route a problem takes when it can’t be resolved where it arose, and how fast. Agreed in advance, or it’s improvised under pressure. More →
Status report
A periodic summary of progress, risks and decisions needed. Valuable when it interprets; wasted when it merely lists what a tool already shows. More →
Stakeholder
Anyone affected by the project or able to affect it. The communication plan exists to serve this list. More →
