Insurers use decision tables to outline all the requirements necessary for policy issuance.
For example, a decision table can verify the occupation, income, and assets owned by a potential policyholder. If the applicant doesn't meet the requirements, the insurer can specify in a decision table what actions are to be taken.
Decision tables differ in the way decisions are represented.
Some tables use True/False values to express the options for a condition. Others may use numbered values, which resemble switch-cases.
Businesses such as online retailers use decision tables to manage their pricing, discounts, and shipping rates.
Lenders consider a wide range of factors before they approve a loan.
Decision tables can contain all the eligibility requirements applicants need to meet for loan approval.
Send a reminder when (invoice is not paid AND is overdue AND customer segment is household) OR (invoice is not paid AND is overdue AND customer segment is company).
That way it is easier to understand and manage later on this table.
A decision table is complete when it contains every possible combination of input variables. In some tools, you can use ranges or wildcards to avoid enumerating every possibility and shorten the decision table.
Also, when there are many decisions to manage, creating several small decision tables is better than using one large table. Running decisions is much easier this way.
