In a recent study of enterprise resource planning (ERP) system effectiveness, researchers asked companies about how they assessed the success of their ERP systems. Out of 335 manufacturing companies surveyed, they found that 201 used return on investment (ROI), 100 used reductions in inventory levels, 28 used improved data quality, and 6 used on-time delivery. In a survey of 200 service firms, 40 used ROI, 40 used inventory levels, 100 used improved data quality, and 20 used on-time delivery. Is there evidence that the measures used to assess ERP system effectiveness differ between service and manufacturing firms? Perform the appropriate test and state your conclusion.
