Product manuals are an essential part of the product. They are given along with the product. They are very important as they establish a better relationship between the product and its user. To a user, it gives a better understanding of the product and also its potential. Very often, product manuals are badly designed. Most often, they give misleading information, which makes it very difficult to understand the product completely. Sometimes they also give insufficient information, which conceals from the user the full potential of the product. By and large, in India, product manuals are not given the professional attention they deserve—both for the text and for the illustrations. They are designed in a very casual manner, or rather, left unattended completely. The textual portion of most manuals is prepared by lower-level employees in industries. These are usually freshly appointed engineers who just make a list of the matters to be covered in the manual. This matter is then arranged in a slightly better way by the advertising department, which ultimately results in a badly designed manual. Hence, it was decided to study and analyse a few product manuals, identify the typical problems and the areas of improvement, and also suggest a methodology for a better design. Several product manuals were collected for this purpose. These ranged from a single page or flap to more detailed booklets. Also, a few foreign manuals were collected along with the Indian Manuals. It is hoped that it will serve as a useful guide to designing a better product manual. It can be used by graphic designers, advertising departments, etc. It can also be used by product designers, who can help the company to design a good manual for their products.
