MKTG90003 Chap.7 Systems and Communication Theory
Systems and Communication Theory
Systems theory explains how organisations respond to environmental feedback. Closed systems ignore it, reactive systems answer without changing underlying behaviour, and open systems adapt structures, processes or goals. The 7 Cs then audit credibility, context, content, clarity, continuity and consistency, channels, and audience capability.
Together they show why effective PR requires management action as well as careful messaging.

Audit an emergency service update
- 1Identify the mismatch between reassuring language and the lived context as a credibility problem.
- 1Replace abstract wording with the affected service, timing, alternatives and next update.
- 1Use established channels accessible to the affected audience.
- 1Determine whether feedback reveals an operational failure that requires adaptation.
- 1Keep facts consistent across channels and correct them transparently as evidence changes.
Key terms
- Closed system
- A closed system ignores environmental feedback and continues existing behaviour.
- Reactive PR
- Reactive PR acknowledges feedback but responds without changing the underlying organisational process.
- Open system
- An open system uses feedback to adapt structures, processes or goals.
- The 7 Cs
- The 7 Cs audit credibility, context, content, clarity, continuity and consistency, channels, and audience capability.
- Audience capability
- Audience capability concerns access, habits, prior knowledge and the effort required to understand or act.
Systems and Communication Theory FAQ
What makes an organisation an open system?
An open system does more than collect comments. Environmental evidence reaches decision-makers and can change structures, processes or goals. The organisation then explains the action and keeps feedback open. A survey or social account does not prove openness if nothing can change.
How do the 7 Cs improve a message?
They test the sender's credibility, the surrounding context, the relevance of content, clarity, consistency over time, channel fit and audience capability. In a case, select the criteria that explain the failure and propose a concrete correction rather than listing all seven automatically.
What is the difference between reactive and proactive PR?
A reactive response acknowledges or answers feedback but leaves the cause unchanged. A proactive open-system response uses feedback to adapt before or while communicating. The distinction depends on what management does with evidence, not on how quickly it publishes a message.
How can systems theory and the 7 Cs work together in one case answer?
Use systems theory to diagnose how the organisation handles environmental feedback, then use the 7 Cs to audit the communication that accompanies its response. Trace the signal from an affected public through listening, interpretation, escalation, authorised decision and visible follow-up.
A closed posture ignores or filters out the signal; a reactive posture acknowledges it without changing the underlying process; an open posture permits evidence to alter structures, processes or goals. Do not label an organisation open merely because it runs a survey or social account. Show that feedback reaches a decision and that the result returns to publics for renewed review.
If the evidence exposes a service failure, operational adaptation must precede or accompany explanation. Then select the 7 Cs that cause the message failure: credibility, context, content, clarity, continuity and consistency, channels, or audience capability. Apply only those supported by the facts.
State the consequence of each weakness and an observable repair, such as naming the disruption, giving accessible alternatives, committing to the next update and using channels the affected public already consults. Consistency does not require frozen wording; updated facts should be corrected transparently while the central account remains coherent.
End by specifying the return signal: what the public can observe, how it can respond and who reviews the new evidence. This integrated structure links organisational learning with credible communication instead of assuming that better copy alone can repair a closed decision process.
Exam move
Take three complaint scenarios and draw a feedback route from public to decision-maker. Mark where the evidence stops. If the organisation acknowledges the issue but does not change the cause, label the response reactive and explain the consequence. If it adapts and reports the action, explain why the system is more open. Next, audit one message with the 7 Cs, beginning with context and credibility.
Choose only the criteria supported by the facts. During exam practice, write the environmental signal, current organisational posture, required adaptation and communication follow-up in four sentences. Finish by naming who supplies evidence, who has authority to act and how the public will see the result.
