DECISION TABLES

1. Understanding Decision Tables A decision table is a powerful tool used to model and analyze complex decision-making processes. It provides a structured and systematic way to map out all possible scenarios, inputs, and corresponding actions or outputs. This visual representation helps businesses, analysts, and decision-makers clearly identify the logic underlying their decisions, leading to more informed and consistent choices. by Srishti Gupta (21001433058) DD BBA-MBA (6 th Semester) System Analysis and Design

2. Anatomy of a Decision Table Conditions The upper-most rows of a decision table represent the different factors or conditions that influence the decision-making process. These could be variables, constraints, or any other relevant input that needs to be considered. Actions The bottom rows of the decision table define the possible actions or outputs that can be taken based on the combination of conditions. These actions are the resulting decisions or outcomes of the process. Rule Sets Each rule set represents a unique scenario, with specific conditions leading to a corresponding action or outcome.

3. Decision Tables in Action: Loan Approval Example 1 Applicant Information The first step in using a decision table for loan approval is to gather all relevant information about the applicant, such as their credit score, income, employment status, and existing debt. 2 Condition Evaluation The decision table is then used to evaluate the applicant's information against the predefined conditions, such as credit score thresholds, debt-to-income ratios, and employment history requirements. 3 Action Determination Based on the combination of conditions met, the decision table will then determine the appropriate action, such as approving the loan, offering a modified loan amount, or denying the application.
