User information for safe and efficient use must be supplied by the manufacturer or supplier along with the product. Especially when dealing with the products without appropriate instructions the user needs to be warned if there are residual risks or the expectations of the user regarding the quality or safety of the product could not be met. Technical writers write such user information but not all of them are trained and experienced to create standardized and user optimized instructions. The resources and documentation processes for the product manufacturers are not always ideal to meet the requirements. Especially, the buyer of machinery and equipment would be well advised to verify the suppliers’ documentation by conducting his own usability tests.
