The Importance of Communication (LC 2027) (Leaving Cert Business): Revision Notes
The Importance of Communication
What is communication?
Communication is the process of transferring ideas, information, and messages from one person (the sender) to another person (the receiver). The main purpose is to ensure the receiver understands the sender's message clearly. This transfer of information creates an interaction or exchange that helps people work together effectively.

Effective communication is a two-way process that requires both the sender to deliver a clear message and the receiver to actively listen and provide feedback. Without this complete cycle, misunderstandings and conflicts can easily develop in business environments.
Effective communicators ensure their messages are clearly understood and can be acted upon. This involves choosing the right words, using appropriate methods, and checking that the message has been received correctly.
The 7 essential elements of communication skills
Successful communication requires mastering several key skills that work together to create professional and effective interactions:
The 7 Essential Communication Skills
- Listening - Having strong observational skills to fully understand the message being conveyed
- Non-verbal communication - Using appropriate body language, posture, and gestures to support your message
- Being clear - Choosing the right words to deliver your message effectively
- Being concise - Using fewer, well-chosen words to avoid confusion
- Being confident - Delivering your message with appropriate confidence and authority
- Being personable - Using a friendly tone and positive expressions like smiles
- Being patient - Remaining composed and unhurried when communicating
These skills work together to ensure your communication is professional, effective, and well-received by others.
Why is communication important in business?
Effective communication brings numerous benefits to organisations and is essential for business success:
Increased productivity
Good communication ensures every employee understands their tasks clearly. When employees know exactly what they need to do, they can work faster and more efficiently, reducing costly errors and misunderstandings.
Avoiding conflict
Clear communication and active listening help prevent disputes between stakeholders in a business. When information is shared openly and accurately, there are fewer opportunities for disagreements to develop.
Increasing engagement
Customers are more likely to have positive experiences when dealing with companies that communicate well. Strong communication skills help build customer loyalty, which leads to increased sales and repeat business.
Supporting collaboration
Effective collaboration requires clear and open communication across the organisation. When accurate information is shared between all staff members, teams can work together more effectively and make better decisions.
Promoting positive culture
Employee morale improves when staff receive clear instructions and feel included in decision-making processes. Honest and transparent communication helps create a positive, healthy, and productive workplace environment.
Managing change
Communication and collaboration help build resilience and trust among staff, enabling businesses to adapt more successfully when facing challenges or changes in their operating environment.
Routes of communication
Communication flows through organisations in different directions, each serving specific purposes in the business hierarchy:
Understanding communication routes helps managers choose the most appropriate channel for their messages and ensures information reaches the right people at the right time.
- Downward: From managers to employees below them in the chain of command (e.g., giving instructions for tasks)
- Upward: From employees to the person they report to (e.g., a salesperson's weekly sales report to their manager)
- Horizontal: Between people on the same level in the organisational structure (e.g., production manager asking finance manager for budget information)
- Formal: Following specific procedures or methods (e.g., letters, reports, monthly meetings)
- Informal: Unplanned and unrecorded communication (e.g., staff discussing business after work)
Modes of communication
Understanding the different modes of communication helps businesses choose the most effective method for each situation:
Verbal (oral) communication
This involves communicating through speech and includes:
- Internal examples: Telephone calls, personal conversations, face-to-face meetings, online meetings (like Zoom)
- External examples: Trade fairs, radio advertisements, videoconferencing with clients
- Benefits: Creates greater productivity as there are fewer communication restrictions and reduces potential for errors
Non-verbal communication
This involves communicating without words through:
- Hand gestures and body language
- Eye contact and facial expressions
- Posture and positioning
- Benefits: Can often convey more meaning than words alone and helps reinforce messages, define relationships, and build trust
Written communication
This involves communicating through written text and includes:
- Internal examples: Memos, noticeboard announcements, letters, social media posts, websites, business documents
- External examples: Brochures, emails, official correspondence
- Benefits: Messages can be efficiently shared and stored, creating permanent records that can be reviewed and revised before sending
Visual communication
This involves communicating through images and visual elements:
- Internal and external examples: Pie charts, photographs, flipcharts, graphs, pictograms, line charts, PowerPoint presentations
- Benefits: Information can be absorbed quickly, easier to understand complex data, and helps overcome language barriers
Specific communication methods
Each communication method has distinct advantages and disadvantages that businesses must consider:
Videoconferencing

Visual information
Visual communication uses different types of charts and graphics to present information effectively:
Types of Visual Communication Tools
- Pie charts: Circular diagrams divided into segments, each representing a piece of information - easy to understand at a glance
- Pictograms: Use shapes to represent numbers of people or objects, making data more engaging
- Line graphs: Show trends over time periods, helpful for tracking changes
- Bar charts: Display numerical information using vertical or horizontal rectangles for easy comparison
- Histograms: Similar to bar charts but focus on one topic with no gaps between bars
These visual tools help overcome language barriers and make complex data more accessible to diverse audiences.
Technology and communication in business
Technology has revolutionised how businesses communicate in the 21st century. Modern companies must adapt to technological changes and embrace new communication methods to remain competitive.

Advantages of technology in communication
Speed: Technology enables real-time interactions across the world and enhances collaboration through tools like email, instant messaging, and videoconferencing
Access: Technology expands global reach for companies, connecting businesses with international markets and diverse customer bases that wouldn't have been possible otherwise
Cost: Artificial Intelligence (AI) and automation have made business communication more efficient, requiring fewer employees to complete tasks faster and more efficiently
Productivity: Cloud-based file sharing, videoconferencing, and mobile technology enable workers to operate from anywhere, increasing overall productivity
Collaboration: Project management software and cloud-based platforms enhance communication and teamwork, while virtual meetings mean team members can work across different locations more effectively
Challenges of technology in communication
Despite the benefits, technology also presents significant challenges that businesses must address:
Critical Technology Challenges
Cybersecurity: Many people are unaware of their consumer rights when shopping online, personal information can be hacked, and online banking faces risks from viruses and scams
Lack of engagement: Promotional emails tend to be generic rather than personalised, which can damage relationships with customers who prefer more personal approaches
Cost: Introducing new technologies requires significant capital investment, including maintenance costs, licensing fees, and staff training expenses
Information overload: Too much information can overwhelm people, and constant emails can lead to decreased focus and productivity among employees
Improving communication in an organisation
Businesses can enhance their communication through several strategic approaches that address common communication barriers:
Composition
Ensure messages use the correct format and are not too lengthy. Poorly composed messages that are overly long or too technical can confuse recipients and delay important processes.
Choose the appropriate method
Select the right communication method that matches your message and audience. Consider factors like urgency, formality requirements, and whether you need a permanent record.
Listen when others are speaking
Active listening is crucial, especially when multiple people are involved in discussions or when there are distractions in the workplace. Management should encourage attentive listening and create systems for valuable employee feedback.
Provide regular feedback
Ensure that messages are delivered appropriately and understood correctly. Establish systems that allow for clarification and prevent misunderstandings from developing into larger problems.
Open communication
Build trust between different parties by encouraging transparency and honest communication. Management should promote both formal and informal communication channels that allow employees to share ideas and concerns freely.
