Choosing communication media
Choose a medium by the richness needed, urgency, cost, need for a record, confidentiality and audience. Rich media suit complex or sensitive messages.
Media richness
Media richness is the ability of a medium to carry meaning and reduce confusion. A medium is rich when it offers several cues (words, tone, face, gestures), immediate feedback, a personal focus and natural language. Face-to-face talk is the richest; a printed notice is among the leanest. The rule is to match the medium to the message: rich media for non-routine, complex, sensitive or emotional messages, and lean media for routine, simple, factual messages to many people.
From rich to lean media
Moving right, each medium carries fewer cues and slower feedback, but reaches more people more cheaply and leaves a clearer record.
Factors in choosing a medium
| Factor | Question to ask | Example |
|---|---|---|
| Purpose and complexity | Is the message simple or complex, routine or new? | A new incentive scheme needs a meeting; a holiday notice does not |
| Urgency | How fast must it arrive and get a reply? | A machine breakdown: phone, not letter |
| Need for a record | Must it be kept as proof? | Contracts, warnings and price quotes in writing |
| Confidentiality | Is it private or sensitive? | Salary matters in a private talk, not a group chat |
| Audience | How many receivers, where, and in which language? | 120 staff on three shifts: notice board plus SMS |
| Cost | Is the cost worth the value of the message? | A visit to Jaffna for a routine order is too costly; email it |
| Feedback needed | Do you need a reply or discussion? | A negotiation needs a meeting or call |
| Receiver's preference and access | What does the receiver use and trust? | An older rural supplier may prefer a phone call |
Rich and lean media
Using lean media for sensitive messages causes hurt and confusion; using rich media for routine messages wastes time.
Example: matching messages to media
Priya Rajaratnam, HR Manager of Nelum Packaging (Pvt) Ltd (a fictional company), has four messages. Choose a medium for each: (a) telling a worker that his contract will not be renewed; (b) reminding all 120 staff that the canteen closes early on Poya day; (c) sending a price quotation to a customer in Jaffna; (d) agreeing an urgent change in today's delivery with a supplier.
- (a) Sensitive, personal, emotional: a face-to-face meeting in private (richest medium), followed by a letter for the record.
- (b) Routine, simple, many receivers: a trilingual notice on the board plus an SMS or staff WhatsApp message (lean media).
- (c) Needs a record and exact figures, receiver far away: an email with the quotation attached, or a letter.
- (d) Urgent, needs instant feedback: a phone call now, then a short email to confirm what was agreed.
(a) face to face, then a letter; (b) notice plus SMS; (c) email or letter; (d) phone call, then a confirming email. Richness rises with the sensitivity and complexity of the message.
Sri Lankan firms mix media: SMS and WhatsApp for quick updates, email for records, face-to-face talks for appraisals and bad news, and newspaper advertisements in Sinhala, Tamil and English for public announcements such as job vacancies.
Structured question: “Explain the factors to consider when selecting a communication medium.” Explain 5-6 factors (purpose, urgency, record, confidentiality, audience, cost, feedback), each with a short example.
Short answer: “What is media richness?” The ability of a medium to carry meaning through several cues, quick feedback and a personal focus. Face-to-face is the richest.
Essay: “Discuss the factors affecting the choice of communication media, using the idea of media richness.” Explain media richness and the rich-to-lean range, match rich media to non-routine messages, explain the factors, and apply them to a set of workplace messages.
Sensitive or complex → rich (face to face). Routine or simple → lean (notice, email). Then check U-R-C-A-C: Urgency, Record, Confidentiality, Audience, Cost.
