Internal Customers vs. External Customers

We talk about customers of design information. It takes many people to realize a product design into something that can be sold and used. Those people need design information to ensure that they're performing their tasks to produce a high-quality product, and to be able to use our product appropriately. We review who our customers are and what type of information they need from design engineers.

Product designers have many customers, both internal and external.

When determining design controls, requirements, specifications, and limits, think of all the customers of that information.

Take a different viewpoint of the design process. Instead of focusing on what's happening and when, focus on who is doing what with the design information. That will help you think of the customers of your design, as you're developing the requirements and specs.
