madhadi.com is a free, public knowledge platform for data integrity, computer system validation, equipment qualification, automation systems, QMS, clinical systems, and GxP quality. Written for practitioners, from people new to the field through senior program leaders.
What I get from this: nothing, except knowing it helped someone avoid learning things the hard way. That's genuinely enough. If it's not useful to you, the tab close button is right there and there is no 6-step cancellation flow, no passive-aggressive popup, and no email sequence asking why you left. And if something is wrong, outdated, or missing, I actually want to know.
This site provides public educational information based on publicly available regulatory guidance, laws, and standards. It is not legal advice, regulatory consulting, or inspection strategy. Nothing here replaces the need to read primary sources, apply professional judgment, and consult qualified experts for your specific situation. Regulatory requirements change, always verify against current FDA, EMA, and ICH documents.
