In any business, it's important to make sure that the goals of the organization are aligned with the decisions that are being made. This means that the business logic - the rules and policies that govern decision-making - must be aligned with the goals of the organization. One powerful way to achieve this alignment is by using decision tables.

What is a Decision Table?

A decision table is a visual representation of a set of rules that can be used to make decisions. It's a grid that shows all the possible combinations of input conditions and the corresponding actions or outcomes. Decision tables are easy to read and understand, which makes them an ideal tool for aligning business goals and business logic.

Case Study - Loan Company

As the property market continues to recover, HPYLoan, a loan company, wants to attract more customers who are looking to purchase a home. To do so, they must develop an effective loan policy that aligns with their business goals.

To achieve this, HPYLoan has created a decision table that outlines their current loan approval policy and identifies areas for improvement. By examining the fourth business rule in the table, they found that requiring a manual review process for home purchasing loans could deter potential applicants.

By studying the forth business rule in the decision table, you can see that if a loan applicant wants to get a loan for home purchasing, it requires a manual review process, which may discourage him/her from applying a loan.

To address this issue, HPYLoan has modified their business rules. They have decided to approve loan requests for home purchasing if the applicant is a current home owner, without the need for further manual review. This change is expected to speed up the loan approval process and make it more attractive for home owners who are looking to purchase a new home.
