Product complexity is a measure of the intricacy of a product or system. It can be quantified in terms of the number and nature of components, the interdependencies among those components, and their respective interactions. When assessing product complexity, it is important to consider internal and external factors influencing its development and execution. Internal complexity factors include the design of components and how they interact with each other to achieve a desired goal. For example, how closely related various parts are, how many steps are required to complete a task, and how complicated the user interface is will all impact internal complexity. External factors include environmental variables such as market trends, customer preferences, and industry regulations which can affect process design decisions.
