What term describes the end result of a process that meets a need or want?

The term that best describes the end result of a process that meets a need or want is "Product." In the context of project management and cost estimation, a product refers to the tangible or intangible item that is delivered to the customer or stakeholder, encapsulating the solution to their needs or desires.

When a process is carried out, whether it be in manufacturing, software development, or service delivery, the outcome that fulfills the initial requirement is categorized as a product. This can include physical goods, digital outputs, or even lists of features in the case of software. Understanding that a product is ultimately what the stakeholder receives creates clarity around project goals and helps in aligning resources and costs effectively.

The other terms listed may have related meanings but do not specifically capture the essence of a completed offering that is designed to meet a particular need or want in the same way that "product" does. "Output" can refer to any result from a process but lacks the implication of meeting a specific need. "Service" pertains more to actions or deeds offered to satisfy a need, while "result" is a vague term that may describe any outcome. Hence, in the context of the question, "Product" is the most accurate choice.
