Which is NOT one of the three essential factors to consider before starting business writing?

The correct answer, indicating that "Topic" is not one of the essential factors to consider before starting business writing, highlights an important distinction in the writing process. When engaging in business writing, it is crucial to understand the purpose of the document, as this guides the overall direction and specific goals it aims to achieve. Equally important is the audience, which involves recognizing who will read the document, as this influences the tone, style, and complexity of the language used.

The medium, referring to the format or channel through which the writing will be delivered (such as email, report, or presentation), also plays a vital role in how the message is crafted and received. In business communication, these three elements—purpose, audience, and medium—are foundational and drive the content and structure of the writing piece.

While the topic is relevant to the subject of the writing, it is not considered one of the critical elements that shape the effectiveness of business communication in the same way as the other three factors. Understanding the topic may come naturally, but focusing on purpose, audience, and medium ensures that the writing is clear, targeted, and impactful.
