Final answer:
Ignoring non-financial information is not a benefit of a cost management system; rather, such systems should integrate all types of relevant data to provide comprehensive insights for decision-making.
Step-by-step explanation:
Among the benefits of a high-quality cost management system are reducing duplicate data storage, improving the timeliness of reports, and increasing the efficiency of generating reliable and accurate information. However, option a, which suggests that a benefit would be to increase speed by ignoring non-financial information, would not be considered an advantage. In fact, ignoring non-financial information can lead to poor decision-making, as cost management systems should ideally integrate both financial and non-financial data to provide a comprehensive view of the organization's performance. High-quality cost management encompasses a holistic approach, considering various factors like efficiency, productivity, and the accuracy of information.
