Business communication involves exchanging information, ideas, and messages within and outside an organization to achieve specific objectives. It is purpose-driven, formal, clear, and professional, and uses various channels and forms, including verbal, nonverbal, formal, informal, interpersonal, group, and mass communication. Business correspondence includes letter writing, presentations, quotations, tenders, sales letters, claims and adjustment letters, social correspondence, memoranda, inter-office memos, notices, agendas, minutes, job application letters, and resumes. Business reports are formal documents that present information, analyses, findings, and recommendations for specific issues or projects that are crucial for decision-making, problem-solving, and strategic planning. Oral presentations, formal or informal, convey information, ideas, or findings to an audience by combining verbal and non-verbal elements to engage and achieve a purpose. PowerPoint presentations and visual aids support the oral presentations.
