Best practices in designing decisions
When creating a business model in Blueriq, one must always aim to model decisions that can be easily understood by the business. To verify whether the level of complexity of th decisions is acceptable, a DRG can be generated at any time in the design process. This DRG is then used to visualize the decision and its sub decisions and by that give insight to a business engineer and for instance an analyst on how this particular decision is made.
Some best practices when designing decisions is given below. It is not to be used as "the one and only way" but should be treated as a possible means to create understandable decisions.
| 1 | Main | Ask yourself the question what the main decision is. If you think of more than one answer, split these decisions if possible. |
| 2 | Type | Note that a decision is not bound to be a Boolean. In general, there are three types of decisions:
|
| 3 | Sub | For each identified decision, determine if the decision is preferably built up in meaningful sub decisions. These sub decisions could be reusable decisions - in fact reusable decisions will most likely be sub decisions - but not every sub decision has to be a reusable decision. Think of a complex calculation where intermediate results are never reused but are created nevertheless, for the sake of understandability. |
| 4 | Circularity | Avoid circularity. When decision A depends on the outcome of decision B and decision B needs the result of decision A as input, you're in trouble! When designing decisions top-down circular references can easily be avoided. |

Prime examples
In this paragraph prime examples of Blueriq's logic contructions are given.
Of course it is subject to discussion whether one logic construction or another is used best, but that will be discussed in chapter 4. Design considerations.
