One of the primary advantages of the Decision-Based Evaluation model over the Kirkpatrick model is that it allows different variables to be measured depending on the target of the evaluation process.

The Decision-Based Evaluation model is designed to be more flexible compared to the Kirkpatrick model. It recognizes that different training programs and interventions have different goals, and therefore, the evaluation process should be tailored to measure the specific outcomes that matter most. This means that the model allows different variables to be measured depending on the target of the evaluation process, making it a more versatile and comprehensive approach to evaluating training and development programs.
