Find the gaps before the auditor does.
A two-week read of your existing management system against the standard you're certified to — or want to be. Output: a gap register, risk-ranked, with named clause references and remediation effort estimates. Read in a board meeting in twenty minutes.
Why this exists. Most certified organisations don't fail audits because the standard is unreasonable. They fail because nobody reads the standard against the system in cold blood. We do.
