Write for the user, not the auditor
Documentation earns its keep when the people doing the work rely on it. Write procedures in plain language, keep them short and put them where they are needed. When documents help staff do their jobs, compliance takes care of itself and audits become easy.
How much documentation is enough?
ISO standards require far less mandatory documentation than many assume. Beyond the few required items, document only what reduces risk or ensures consistency. Less, well-maintained documentation always beats a large library nobody keeps current.
Keeping documents under control
Document control means the right version is available and old versions are withdrawn. A simple register, clear ownership and a regular review cycle are usually enough. Over-engineered control systems create work; a light, disciplined approach keeps everything current.
