Managing validation rules in Salesforce is crucial for maintaining data integrity and enforcing business rules. When a validation rule needs to be removed you must decide whether to deactivate or delete it. Deactivating a rule temporarily disables it while keeping it available for future use making it useful for testing or troubleshooting. In contrast deleting a rule permanently removes it from Salesforce which is only recommended if it is no longer relevant.  

Properly managing validation rules in Salesforce ensures a well organized system that prevents unnecessary errors and conflicts. Regularly auditing rules, documenting reasons for deactivation or deletion and testing before making changes can help maintain system efficiency. If unsure about removing a rule permanently deactivating it first allows you to assess its impact before deciding on deletion. Businesses can optimize data accuracy by effectively handling validation rules while keeping Salesforce workflows running smoothly.
