What term describes individuals or groups that are invested in the design process?

The term that best describes individuals or groups invested in the design process is "Stakeholders." Stakeholders include anyone who has an interest in the project or is affected by its outcomes, which can encompass a wide range of participants such as clients, team members, users, and even community members. Their involvement is crucial because they provide insights, requirements, and perspectives that shape the design and ensure that it meets the needs and expectations of those who will be impacted.

While clients specifically refer to those who typically hire designers to create a product, the term "stakeholders" is broader, as it includes clients but also encompasses other parties who may not have a financial stake but still have a vested interest in the project's success. Similarly, while the audience refers to the end-users or recipients of the design’s message, they are just one subset of stakeholders. Market researchers conduct studies to understand consumer needs and trends, but their role is more focused on data gathering rather than directly influencing the design process itself as stakeholders do.
