Almost as soon as the Sarbanes-Oxley Act was passed in 2002, vendors appeared with Sarbanes-Oxley solutions. Almost all of these products predated the passage of the act and have been repurposed to take advantage of this new market. Here are the different types of products.Business process managementWhat it does: This is workflow software on steroids. These products link with existing systems and can enforce policies, such as who can approve transactions or what happens when customers return products they\u2019ve already paid for.How it enforces compliance: Ensures that corporate policies are followed.Weaknesses: Only puts in place a set of rules. The actual transactions take place in the underlying systems.Document managementWhat it does: Establishes a logical way to store and manage documents.How it enforces compliance: The biggest part of Sarbanes-Oxley compliance is documenting processes. Weaknesses: Can\u2019t guarantee that the processes are actually followed.Revenue managementWhat it does: These systems automatically extract financial information from ledgers or ERP systems.How it enforces compliance: Removes human error in certifying accounting.Weaknesses: Doesn\u2019t ensure that the proper processes were followed when the numbers were generated in the first place. Fraud in, fraud out.Single instanceWhat it does: Takes all your ERP systems and replaces them with one.How it enforces compliance: Because every system is integrated and automated, there\u2019s no need for human intervention and no (apparent) opportunity for fraud.Weaknesses: Breathtakingly expensive, disruptive and time-consuming to implement.-B.W.
