Examples
In Planguage we differ from conventional usage of this term in that:
• we assume that both Product-Values and costs can be expressed numerically as Requirements, and Design-Ideas can be estimated for Impacts in terms of multiple measures of Product-Values and of costs
• any useful set of one or more Attributes can be chosen at any time to represent an interesting set of Product-Values or costs
• the costs are any Idea of Resources, and not limited to financial costs
Notes
Abbreviation: Q/C ratio.
