Before you begin
- Use the organisation's objectives, workforce context and stated communication needs to evaluate the structure or HR choice.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
What is horizontal communication?
What you will learn
- Explain how communication moves through a business
- Distinguish one-way from two-way and vertical from horizontal
- Assess channel problems and suitable improvements
Direction describes who communicates with whom
Vertical communication moves up or down levels of a hierarchy. Upward communication can carry feedback or concerns; downward communication can convey goals, instructions and decisions. Horizontal communication occurs across people or functions at a similar level and can coordinate interdependent work.
One-way communication sends information without a planned reply. Two-way communication allows questions, feedback or negotiation. Two-way channels can uncover misunderstanding but require time and a response process.
Channels can distort or delay messages
Messages may be filtered, delayed, misunderstood or lost across handovers. Upward concerns may be suppressed; downward instructions may be interpreted differently; horizontal teams may use inconsistent data or systems.
Map the sender, receiver, direction, intended response and point where the message may fail. Use acknowledgement, shared records or a named contact when a missed message has material consequences.
Pause and explain
A supervisor sends a change to staff with no opportunity to respond. What type is this?
Worked example
A head office changes a return policy, branch supervisors relay it to staff, and staff report recurring customer problems back to head office. Identify the directions and where two-way feedback occurs.
Show the worked solution
- Head office to supervisors and staff is downward vertical communication.
- Staff concerns back to head office are upward communication.
- A feedback route makes the exchange two-way.
Answer The policy travels down the hierarchy from head office through supervisors to staff. Reports from staff back to head office are upward communication. If head office collects and responds to those reports, the overall channel is two-way rather than a one-way announcement.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A product team cannot learn that customer complaints have increased because branch reports pass through three managers and are summarised. Identify the channel risk and one improvement.
Give me a hint
Check upward filtering and whether the original evidence survives handovers.
Compare my reasoning
- Upward feedback may be delayed or filtered.
- Create a direct structured route for complaint data.
- Keep manager review while allowing urgent cases to escalate.
The upward channel may delay or filter the complaint pattern before it reaches the product team. A shared reporting form or dashboard could pass categorised evidence directly to the responsible team, with managers still reviewing trends and a clear escalation path for urgent issues.
Look for these in your work
- Direction and distortion are named
- A fitting channel change is proposed
- Oversight is retained
Two departments use different versions of a customer order spreadsheet. Explain how this horizontal communication problem could affect service and how to address it.
Give me a hint
Consider inconsistent information at a handover.
Compare my reasoning
- Different records can create conflicting instructions.
- Orders may be delayed, duplicated or incorrect.
- Use one controlled source, ownership and update alerts.
The departments may act on different customer details, causing duplicate work or incorrect delivery. A shared controlled record with clear ownership, access rules and update notifications can align the teams; the business should test permissions and train staff before relying on it.
Look for these in your work
- Information mismatch is linked to service
- Shared channel is specified
- Controls and training are considered
A company uses a one-way text alert for a major role change. Explain what a two-way channel should add and how management should close the loop.
Give me a hint
Provide a safe way to ask questions and publish answers or unresolved issues.
Compare my reasoning
- Employees need questions and individual impacts addressed.
- Managers should record recurring concerns and decide actions.
- Publish answers and dates for remaining decisions.
A two-way meeting or private question channel allows employees to ask how the change affects their role and raise concerns. Management should log themes, respond to common questions, state what remains undecided and give a date for updates so employees can see that feedback was considered.
Look for these in your work
- A genuine reply route is added
- Concerns are processed
- The loop is closed with updates
Common mistakes
- Equating vertical with written and horizontal with spoken
- Assuming a reply button creates meaningful two-way communication
- Ignoring filtering or delay between levels

Communication between people or teams at a similar level

Make it stick
How do communication direction and feedback shape whether information reaches the right people intact?
