Research Question: How can response time statistics in ERP transaction systems be better understood and measured?

Methodology: The study uses heuristic rules and log-normal distribution analysis to understand response time statistics in ERP systems.

Results: The study found that response time distributions in ERP systems are generally log-normal or a sum of two or more log-normal distributions. The authors present arguments based on heuristic rules for this form of distribution and provide data from performance measurements in actual systems to support their claim.

Implications: The findings suggest that log-normal distribution should be considered when interpreting response time data and creating service level agreements. This is because log-normal distributions are skewed and have a tail for longer response times, making mean value agreements less suitable in specific situations.

Keywords: ERP system, performance, response times, response time distribution
