• Communication is critical to the success of any business.
  • The means through which information flows within and beyond the organisation are referred to as communication channels.
  • Communication can be professional or casual, and it can occur horizontally, vertically, or in a one-way or two-way fashion.

Horizontal (Lateral) Communication

  • Communication between people on the same level or department within an organization
  • It helps in sharing information, knowledge and resolving issues among colleagues.

Vertical Communication

  • Communication between different levels of management within an organization.
  • It involves information flowing either upwards (from subordinates to superiors) or downwards (from superiors to subordinates).
  • It helps in the efficient flow of information and decision-making within the organization.
  • Vertical communication can be upward or downward
  • Upward communication refers to the flow of information from lower-level employees to higher-level management.
  • This type of communication can help to identify problems, provide feedback on policies and procedures, and offer suggestions for improvement.
  • For example, an employee may provide feedback to their manager about issues with a particular process or suggest a new approach to improve efficiency.
  • Downward communication refers to the flow of information from higher-level management to lower-level employees.
  • This type of communication can help to communicate organizational goals and objectives, provide instructions for tasks and projects, and inform employees about changes in policies and procedures.
  • For example, a manager may communicate new procedures to their team or provide guidance on a specific project.

  • Communication in which information flows in only one direction.
  • It is often used for conveying instructions, rules, or regulations.
  • There is no room for feedback or clarification.

Example: An employer providing instructions to an employee.


  • It is quick and efficient in conveying information.
  • It is useful for situations where there is no need for feedback or clarification.


  • It can lead to misunderstandings due to the lack of feedback or clarification.
  • It does not promote collaboration or teamwork.

Two-Way Communication

  • Communication in which information flows in both directions.
  • It is essential for effective feedback, conflict resolution, and decision-making.
