Ideality is how you assess how good something is: you consider the proportion of benefits (all the things you want) over its costs (all inputs) and harms (all outputs you don’t want). Measuring Ideality is a quick and simple way to understand the pros and cons of your systems and processes: you can start by checking you have all the benefits you want and also identify any problems and see how to solve them.

Your inputs (costs) result in functions, which give you two kinds of outputs: outputs you want (benefits) and outputs you don’t want (harms). When you problem solve, you improve Ideality by improving your functions; that is, reducing harmful functions, improving insufficiently useful functions and reducing input functions.
