Technical writing is a special style of writing used to communicate information such as description of a computer operation or steps to use a microwave oven to the end user. Technical writing is more than "What to do?” ”How to do" write ups. It is a vital link between the product features and the usability of those features by the end user.

Technical writers are otherwise called as technical communicators. They communicate; they facilitate; they sensitize the user to the features of the system and enable the user to use the system with ease.

For example: When a product is introduced in the market, the product succeeds only if it is used as intended. A user manual or a user guide will help the user to use the product to its maximum potential with minimum efforts.

Technical writer writes for wide variety of audiences such as end users, IT professionals, developers, knowledge workers etc. Therefore, the writing style, language and the tone may differ according to the audience.

End user documents are generally written using simple English called Global English. Using short sentences and using active voice are some of the techniques of simple English. Using simple English eliminates jargons which confuses the user. Simple English is for every one: from the lay man to the business managers.

The tone may differ according to the audience and purpose. For example: if a writer wants to give a general overview of the application, he may use the descriptive tone. If he wants to guide the user with set of steps to accomplish a task, he may give instructions.
