Cascading Drools Rules

                 URL: https://jira.jboss.org/jira/browse/JBRULES-2334
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-guvnor
    Affects Versions: 5.0.1.FINAL
         Environment: Tomcat, Drools, Java, Oracle
            Reporter: Brian Do
            Assignee: Mark Proctor


I have a business requirements to develop a lead score algorithm.  The algorithm is a summation of various data fields.  Each data field has different values, and each of that value represent a score.

For example: Job Function = (CEO, President, CFO, Director, Manager)
CEO = 30
President = 30
CFO = 30
Director = 20
Manager = 15

Time Frame = (Immediately, One Week, One Month, Not Sure) where Immediately = 30, One Week = 25, One Month = 20, Not Sure = 5

Department = (Sales, Support, Engineer) where Sales = 30, Support = 30, Engineer = 20

We need to determine the score of each value of each field and sum them up to get a final score.

My question is is there an easy way to do this using Drools Guvnor.  Is there a way to cascading rules?

If we use rules, then it's gonna be something like this:
rule1: if job_function = CEO then score = 30
rule2: if job_fuction = President the score = 30
rule3: if job_function = CFO then score = 30
...
rule#: if time_frame = Immediate then score = 30
...
rule#: if department = Sales then score = 30

The challenge is how do I keep track of the score of each rule in each scoring category and then sum them up at the end.

Thanks,
Brian
