Do not use industry jargon and unknown terms when communicating with customers. They will ignore you. Speak to them in common layman terms that are easy for nearly anyone to understand. Make assembling and operating your products EASY to understand. Write customer instructions which are included inside and outside the packaging for all buying groups and ages. Test out these written instructions on internal employee and test groups before including them with your products. If those test groups do not understand your written instructions or have different understandings of the materials, neither will your customers and you will be paying for unnecessary refunds for product returns. Customers will become angry, give up and come get their money back. Worse yet, they will tell others not to buy your products. Customers have no problem asking for their money back when they think the product fails. If you cannot tell them how to operate or care for the item they just bought, you will pay for it with returns and customer dissatisfaction. You will eat the cost because of your inadequate preparation.
