Reading
Project managers spend most of their working day communicating. PMI's position is that this should be
designed, not improvised: who needs what information, when, in what format, through which channel, and how
you will know it was understood. That design is the communications management plan, and it is built
from the stakeholder register and engagement plan, not from habit.
Doubling a team from 4 to 8 people does not double its communication channels, it nearly
quintuples them, from 6 to 28. That is why adding people to a late project makes it later, and why the
communications plan has to be deliberate rather than habitual.
The three communication methods
Method
How it works
Good for
GCHS example
Push
Sender pushes information to specific recipients; no guarantee it was read or understood
Routine distribution to a known list
Weekly progress email to the funder; text alert about a schedule change
Pull
Recipients access information at their own discretion from a shared location
Large volumes, large audiences, reference material
Shared drive of drawings and specs; intranet knowledge base
Interactive
Real-time, multidirectional exchange between two or more parties
Complex, sensitive, or ambiguous topics needing shared understanding
Homeowner walkthrough; daily standup; negotiation with a supplier
The distinction the exam tests: push and pull both distribute; only interactive reliably
confirms understanding. When a question involves conflict, bad news, ambiguity, or an important decision,
interactive wins. When a question involves routine distribution to many people, push or pull is efficient and
appropriate; using a meeting for something a report would handle is its own failure.
The channel formula
The number of potential communication channels in a group of n people is n(n-1)/2. Six people
have 15 channels. Ten people have 45. Add two more and you are at 66. Complexity grows roughly with the square of
team size, which is why small teams communicate so much more easily and why adding people to a late project makes it
later.

Exam habit: read carefully whether the question asks for total channels at the new size, or the
increase in channels when people are added. If a team of 8 grows to 10, the answer to "how many additional
channels" is 45 minus 28, which is 17. Also watch whether the project manager is included in the count.
Key points
Push and pull distribute; interactive confirms understanding
Channels = n(n-1)/2: watch for total versus additional, and whether the PM is counted
The communications plan is derived from stakeholder analysis, not from habit or convenience
Communication is not complete until the message is received and understood: build in feedback loops
Information radiators make status pull-based, always current, and impossible to spin
Feedback loops and active listening
A message sent is not a message received. Feedback closes the loop: asking the receiver to restate the request in
their own words, confirming decisions in writing after a verbal agreement, checking that a text message about a
schedule change actually reached the crew lead. Active listening is the receiving-side discipline: giving full attention, asking open questions, paraphrasing back, watching nonverbal signals, and holding your
response until you have understood. Most site disputes at GCHS trace to someone hearing the first ten seconds of a
concern and answering the problem they assumed rather than the one described.
Barriers worth naming: noise on an active jobsite, jargon that excludes homeowners, cultural and language
differences, time zones and shift patterns on virtual or distributed teams, and hierarchy that makes people
reluctant to raise problems upward. Each barrier has a countermeasure, and identifying the barrier is usually the
first move.
Information radiators and adaptive communication
Adaptive teams favor transparency over reporting. An information radiator, also called a big
visible chart, is a display in the team's working space that shows real status without anyone asking: a task board,
a burndown or burnup chart, an impediment list, a cumulative flow diagram. In a GCHS site trailer that might be a
whiteboard showing each home's stage, blockers, and inspection dates. Radiators are pull communication that is
always current and difficult to distort, which is exactly why they reduce status-meeting load.
Daily standup: short, time-boxed, team-owned coordination. Its purpose is to synchronize and
surface impediments, not to report status to the project manager.
Iteration review or demo: stakeholder-facing inspection of working results on a cadence.
Retrospective: team-facing process improvement.
Osmotic communication: the ambient learning that happens when a team works in the same
space and overhears relevant conversation. Co-location's real advantage.
Virtual and distributed teams
Remote work removes osmotic communication and nonverbal cues, so it must be replaced deliberately: video on for
discussions that matter, explicit written decisions, shared digital radiators everyone can see, and communication
norms agreed as ground rules. When an exam question describes misunderstanding on a distributed team, look for the
answer that restores richer, more interactive contact, not the one that adds another report.
Managing communication as work
Plan it, then monitor it. Signs the plan is failing: the same question asked repeatedly, stakeholders surprised by
known information, meeting fatigue, decisions made in side channels, and reports nobody reads. The response is to
revisit the plan against actual stakeholder needs, not to send more. Communication overload is as damaging as
silence: a homeowner copied on 40 supplier emails is not better informed, she is buried.
AI assistance is increasingly part of this: drafting audience-appropriate updates, summarizing long threads,
translating technical language into plain terms for homeowners, and generating first drafts of sustainability and
community-impact reporting for funders. The project manager remains accountable for accuracy, tone, confidentiality,
and for the judgment about which conversations must stay human.
Practice Questions
1. A project team has 8 members including the project manager. Two additional members join. How many ADDITIONAL communication channels are created?
17
45
28
10
Answer: a. Channels are n(n-1)/2, so 8 people give 28 and 10 people give 45; the increase is 45 minus 28, which is 17. Choosing 45 answers the total rather than the additional channels the question asked for.
2. A project manager must deliver news of a four-week delay to an anxious homeowner. Which communication method is MOST appropriate?
Pull: posting the revised schedule to the shared drive
Push: a text message with the new completion date
Interactive: a conversation where she can ask questions and the PM confirms understanding
Push: a detailed email explaining the cause of the delay, the revised dates, and the recovery steps
Answer: c. Sensitive or emotionally loaded news requires real-time, two-way exchange so concerns surface and understanding is confirmed. Push and pull distribute information but cannot verify that it landed or address the anxiety behind the questions.
3. Which is the BEST example of pull communication?
A daily standup
A weekly status email sent to the funder and the board with a summary of progress and issues
A phone call to the code official
A shared drive of drawings and specifications that stakeholders open as needed
Answer: d. Pull communication places information where recipients retrieve it at their own discretion, which suits large reference volumes. Emails push to recipients, while calls and standups are interactive.
4. A team of 5 grows to 12. What is the total number of communication channels at the new size?
78
10
55
66
Answer: d. Applying n(n-1)/2 with n=12 gives 12 times 11 divided by 2, which is 66. Answering 55 would incorrectly use n=11, and the sharp rise from 10 channels illustrates why complexity grows near the square of team size.
5. Which BEST describes the purpose of a daily standup on an adaptive team?
To review completed deliverables with stakeholders
For the team to synchronize its own work and surface impediments
To report status to the project manager
To assign tasks for the day
Answer: b. The standup is team-owned coordination that makes blockers visible quickly. Turning it into a status report to the PM or a task-assignment session removes the self-organization that makes it work.
6. A homeowner is copied on 40 supplier emails per week and says she has no idea what is happening. What is the BEST corrective action?
Revisit the communications plan and give her a concise, plain-language update she can use
Add a weekly summary email on top of the existing supplier traffic, copying her and the sponsor
Remove her from all project communication
Ask her to read the emails more carefully
Answer: a. Overload is a communications planning failure, and the fix is right-sizing content to the audience rather than adding volume. Adding a summary on top leaves the noise in place, and removing her entirely swings to silence.
7. A project starts with 6 team members. Four more join. How many ADDITIONAL communication channels are created?
24
30
45
15
Answer: b. Six people give 6x5/2=15 channels and ten people give 10x9/2=45; the increase is 45 minus 15, which is 30. Answering 45 mistakes the new total for the additional channels the question asked about.
8. A team has 9 members, one of whom is the project manager, who communicates only through written status reports rather than direct channels. How many direct communication channels exist among the remaining 8 team members?
21
36
45
28
Answer: d. With the project manager excluded from the direct-channel count, n=8 gives 8x7/2=28. Using all 9 members would give 36, which is why the exam wants you to check carefully whether the PM belongs in the count.
9. A distributed team frequently misunderstands written instructions, and cultural differences add to the confusion. What is the BEST first step?
Increase interactive communication, such as video calls, to build understanding
Assign a single interpreter to handle all written and verbal communication between the team members
Reduce meeting frequency to limit confusion
Move all communication to formal written memos
Answer: a. Ambiguity and cultural difference are exactly what interactive, two-way exchange resolves, since it lets misunderstandings surface and get corrected in real time. More written memos or fewer meetings both remove the feedback loop that is actually missing.
10. Which of the following is the BEST example of an information radiator?
A quarterly newsletter to funders summarizing progress on every home in the program
A monthly steering committee slide deck showing the status of every home and open issue
A private spreadsheet the project manager updates weekly
A site trailer whiteboard showing each home's stage, blockers, and inspection dates
Answer: d. A radiator is pull communication, always current, visible in the team's own space without anyone asking. A private spreadsheet or a periodic report to an outside audience is not visible to the team in real time and does not meet that bar.
11. A hybrid GCHS project posts the permitted construction drawings to a shared project drive for anyone to consult, and holds a live weekly call with the homeowner for finish selections. Access to the drawings is BEST classified as:
Escalation
Push
Pull
Interactive
Answer: c. Stakeholders retrieve the drawings from the shared drive at their own discretion, which is the definition of pull communication. The weekly call, by contrast, is the interactive method, used here for the finish selections that benefit from real-time exchange.
12. A project manager runs the daily standup as a status report directly to themselves, calling on each team member in turn. What is the BEST corrective action?
Continue as is, since the project manager needs a status update from every person each day
Return the standup to the team to synchronize its work and surface impediments
Replace the standup with a weekly written report
Extend the standup to allow more detailed reporting
Answer: b. The standup's purpose is team self-synchronization, not PM-directed reporting, and running it as the latter defeats the mechanism. Replacing it with a report or extending it for more detail moves further from that purpose rather than back toward it.
13. Which barrier is addressed by turning cameras on for a distributed team's important discussions?
Loss of nonverbal cues and osmotic communication
Hierarchical reluctance to raise problems
Jargon that excludes homeowners
Time zone differences
Answer: a. Video restores facial expression, tone, and some of the ambient awareness that co-located teams get for free through osmotic communication. It does not resolve jargon, time zones, or hierarchy, each of which needs its own countermeasure.
14. Stakeholders complain of meeting fatigue but also say they still miss critical updates. What is the BEST response?
Cancel all meetings
Send more emails in addition to the meetings already happening, copying every stakeholder
Revisit the communications plan to match method and frequency to actual needs
Add one more meeting to catch what was missed
Answer: c. Fatigue alongside missed updates is a sign the plan does not match actual needs, not a sign that volume is too low or too high in isolation. Adding more of the same channel treats the symptom without fixing the mismatch.
