OP+IP = Problem Definition

>The list of OPs and IPs defines the problem under consideration, and practically any problem can be defined this way on 1 to 2 pages. The OPs have to be defined by the problem-owner, and the IPs are defined by the questions "What are the important IP? and "For which IPs can we expect to find values, ie examples?" KHE experts can be helpful to find the most powerful and convenient IPs, together with the problem owner.

> Besides of numeric parameters, verbal parameters often can do a great job to meet the problem-specific know-how situation in a compact and accurate way, especially in highly interdisciplinary contexts, and the resulting mixed parameter sets (MPSes) become the key for powerful and successful CAEBM projects.

> Additionally, normalization and standardization of the parameters can simplify many problem situations. And in specific cases taking into account of partial SBM know-how or even rule-based know-how from reliable sources can be helpful to concentrate the EBM on the really unknown part of the project at hand. All this of course will influence the parameters in the OP + IP list.

> So a carefully, if appropriate iteratively defined list of OPs + IPs, always with the availability of fitting examples (= sets of values for IPs and OPs) in mind, is the important entry point for any successful CAEBM project.
