The term "communication lines" refers to the channels or methods used for transmitting information between two or more parties. This can include various forms of communication such as verbal, written, electronic, and nonverbal cues. The effectiveness of these lines depends on factors like clarity, accuracy, timeliness, and relevance of the message being conveyed. In a business context, maintaining open and effective communication lines is crucial for efficient decision-making, conflict resolution, employee engagement, and overall organizational success.
