DESIGN CRITERIA – 2. Design Criteria
Design criteria are the precise goals that a project must achieve in order to be successful.
What is a Design Criteria?
Design criteria are the really important goals that must be achieve in order for a project to be successful. You should not be vague and make your design criteria short and specific as you can. No Goldilocks statements, “Not too big, not too small”.
Do you have to achieve every design criteria set?
Simple answer no, though the criteria are set to help produce the ideal product. So if you start missing out loads of points then your product won’t be the best. You can split the design criteria into two groups. The first group would be the ones that would make a successful project; so by missing these out the project would be unsuccessful. The second group would be the items that are highly desirable but not absolutely important.
How do you decide which criteria to use?
It is not always easy to make that decision. You have to analyze your needs for the project and put them in order of importance. You will need to ask yourself or even your customer, would it be better that the product looks better than it works; or that a low cost is more important than it lasting a long time (reliability).
Below is a list of possible criteria points.
Utility and function, Materials, Aesthetics, Economics (value), Human interface (ergonomics), Social appeal, Environmental soundness, Personal appeal, Reliability, Life-cycle.
