Let’s talk about “Good design helps a product be understood”.A product that has good design will be instinctual and indicative of its usage. This helps make a product self-explanatory and reduce the need for complicated manuals, which if we are honest very few people ever thoroughly read. Therefore if you want your product to be used to its maximum effectiveness then this is a factor that needs to be considered.

This is a factor commonly focused upon within user interaction. If it is designed well it will be easy to understand, however bad design will make the product difficult and annoying to interact with and thus people will actually avoid using it. An example of bad user interfacing is with the below ticket machine where the users were so confused by it they actually vandalized it to make it easier for others to use.

These factors can also be applied to product design in terms of form. By this I mean that if a product is designed to be held a specific way in order to provide maximum usage, that the product or casing of it is designed in such a way as to ensure the user’s hand is in the correct position. This can be tied with ergonomics, but also should be a factor during focus group testing. By simply placing the item on a table without the group viewing and then asking them to pick it up as they would to use it can show any problems with the form that confuses the user.

Again this is a contextual area since people interact with products differently.
