The best way to ensure the quality and integrity of test procedures used in audit analytics is to centralize procedures and implement change control. Centralizing procedures means storing themin a common repository that can be accessed and updated by authorized users. Change control means implementing a process for tracking, reviewing, approving, and documenting any changes made to the procedures. This ensures that the procedures are consistent, accurate, reliable, and secure. References: CISA Review Manual,
