This chapter discusses typical design considerations when designing and implementing decisions using Blueriq.

Setting a boolean value?

Blueriq offers multiple possibilities to set a value for a boolean result, these are listed below:

1. Using a constant value and a business rule to set the contrasting value if a condition is true.
   
   
   
   
2. Use two business rules that set a value
   
       

3. Using a decision table
   
   

   It is tempting to skip the column for male, but it is advised to model a complete table.

What to use?

The choice of method is often based on the preference of the business engineer. But the recommendations are listed below:

1. When the result is dependent on multiple input values, use the decision table
2. When the result is dependent on a calculation use a form with a business rule
3. Make an agreement in an architecture document which form to use. A consistent use of a style throughout a project will help the maintainability of a project.
