The most significant risk from not testing patches before putting them into production is the lack of system integrity. Patches are software updates that fix bugs, vulnerabilities or performance issues in an application system. However, patches may also introduce new errors, conflicts or compatibility issues that could affect thefunctionality, reliability or security of the system4. By not testing patches before putting them into production, the organization exposes itself to the risk of system failures, data corruption or unauthorized access. Loss of application support, outdated system documentation and developer access to production are also risks from not testing patches, but they are not as significant as the lack of system integrity.

Implementing business rules to validate employee data entry is the best way to reduce the likelihood of future occurrences of poor data quality that cause customer complaints about receiving different items from what they ordered on the organization's website. Business rules are logical statements that define the conditions and actions for data validation, such as checking for data completeness, accuracy, consistency, and integrity. Assigning responsibility for improving data quality, investing in additional employee training for data entry, and outsourcing data cleansing activities to reliable third parties are also possible ways to improve data quality, but they are not as effective as implementing business rules to validate employee data entry.
