Answers
User Requirements - The user will provide informal statements that must be transformed into the language of engineering and the design process. These are often a mix of goals, functions, means, constraints, and specifications.
Objectives - Objectives, or design goals, are the desired attributes of the design, what the design will "be" and what qualities it will have. They are often adjectives and characterized by present participles such as "are" and "be." Ideally, they are separated into primary and secondary objectives. Objectives allow exploration of the design space to select amongst alternatives that are at least acceptable or satisfice.
Constraints - Constraints are strict limits that a design must meet in order to be acceptable. They limit the size of the design space.
Metrics - Metrics measure how well the objectives are met.
Functions - Functions are often expressed as verb-object pairs. They describe what the design (or, more likely, an object within the design) will "do" or accomplish, with an emphasis on input-output transformations.
Specifications - Specifications measure how well the functions must perform.
Means - Means, or implementations, are methods of executing or realizing the functions that the design must perform. They represent specific design choices.
