AccuracyCan be vague; details are easily forgottenCan be planned, checked and made precise
Best forUrgent, personal or sensitive matters, and building relationshipsDetailed, technical, legal or routine matters, and many receivers

Non-verbal and visual methods

  • Kinesics (body movement): gestures, posture, facial expression and eye contact.
  • Paralanguage: how something is said, such as tone, pitch, speed, volume and pauses.
  • Proxemics: the use of space, e.g. how close people stand, or the layout of an office.
  • Chronemics: the use of time, e.g. arriving early or keeping someone waiting.
  • Appearance: dress, grooming, uniforms and the look of an office.
  • Visual communication: charts, graphs, signs, logos, posters, colour codes and pictures. Useful when the audience speaks different languages.

Formal and informal communication

FormalFollows the official lines of authority, e.g. circulars, reports, minutes, official letters. Reliable and recorded, but can be slow and rigid.
Informal (grapevine)Unofficial talk at tea breaks, in corridors or in chat groups. Very fast and shows staff feelings, but can spread rumours and half-truths.

A wise manager uses formal channels for decisions and listens to the grapevine to learn what staff are worried about.

Choosing the right method

  • Purpose: to inform, instruct, persuade or build goodwill.
  • Urgency: urgent matters need a call or a face-to-face talk.
  • Need for a record: contracts, warnings and policies must be in writing.
  • Receiver: location, language, literacy and number of receivers.
  • Confidentiality: sensitive matters need a private talk or a sealed letter.
  • Cost: compare the cost of the method with the value of the message.
In Sri Lankan business

A Sri Lankan bank uses written methods for loan agreements (a legal record), oral methods at the counter and on the phone, and visual methods such as queue numbers, signs and posters in Sinhala, Tamil and English.

Exam angle

Structured question: “Compare oral and written communication.” A comparison table: examples, speed, feedback, record, accuracy and best use. End with one line on when to use each.

Short answer: “What is paralanguage?” Paralanguage is the way something is said (tone, pitch, speed, volume and pauses), which adds meaning to the words.

Essay: “Explain the methods of communication available to a business, with their merits and limitations.” Cover oral, written, non-verbal and visual methods, each with two merits and two limits; add formal and informal channels; end with how to choose.

Remember it

Verbal = words (oral + written). Non-verbal = no words (body, voice, space, time, looks). Visual = pictures (charts, signs). Pick by purpose, urgency, record, receiver, cost.
