Creating Rules in BRFplus: Complicated Example 9.3
왘 Color
Also mandatory: most of the time, the customer chooses green.
왘 Monster model
Also mandatory: the best-selling model is the ever-popular “bolts through the
neck.”
왘 Minimum oxtail soup percentage
Optionally, a customer can specify the minimum percentage of oxtail soup to
be in the monster’s blood. This is n eeded to keep the monster warm during
cold nights.
왘 Growth percentage
Optionally, a customer can specify that, when angry, the monster increases in
size by a specified percentage.
왘 Early age strength
Normally, a monster achieves its full strength at 28 days old, full strength being
defined as being able to carry 25 elepha nts on one finger without breaking a
sweat. Since that is usually good en ough, specifying early age strength is
optional. If a customer needs a strong monster in a hurry, though, then the customer
can specify “early age strength”— for example, 20 elephants by seven
days old.
In addition, the business expert has provided requirements about how to split up
ingredients appropriately in the form of a spreadsheet ; as you can see, the columns
in the spreadsheet correspond to the parameters that the customer has to
enter when specifying their monsters’ requirements. The actual spreadsheet goes
on forever; a small subset is shown in Figure 9.29.
