A management system is a way of doing business. If it is more complicated than the work, people will work around it, and the auditor will find the workaround.
WCH writes short, practical procedures. Records live in a centralized, accessible place — not on individual desktops. The quality manual describes stakeholders, responsibilities, and process interaction without becoming literature.
Complexity is often sold as thoroughness. It is usually fear: fear of a missing clause, fear of a picky auditor. The better response is a process that is followed, sampled, and improved. That is what 100% certification success looks like in practice.
After certification, simplicity is what keeps surveillance cheap. You can find a record. You can train a new supervisor. You can add a site. That is the system we are hired to leave behind.
