The order that works
Most first registers start with the policy and stop there. The order that survives an audit is: name the systems and the roles, write the policy and the role authority, set the impact and the thresholds, design the information and the override, keep the logs and measure, then review and correct. The six themes follow that order, from accountability through impact, life cycle, information and use to assurance.
If you have one week, do accountability and impact. If you have a quarter, do all six. If you have a board pack due, do accountability and information, because those are the two an auditor can test in an afternoon.
