Why engineers choose Mizan Quality

Not just a platform built by a programmer. It was built by a quality engineer with 10+ years on the factory floor, who knows the challenges you face: a customer complaint, an audit coming up, a report due yesterday, and a problem that must not come back.

Numbers you can defend

Every calculation is tested against published references and specialized statistical software, so your Cpk is the same Cpk your customer gets.

A report with your name on it

PDF and Excel reports carry your name and your company logo, ready to send to your customer or your auditor.

Nothing to install

Open it in the browser on a laptop or a phone, in Arabic or English. No license keys, no IT ticket.

الحكم
العملية مستقرة إحصائيًا لكنها غير قادرة

قيمة Cpk تساوي 0.90 وهي أقل من الهدف 1.33. التشتت يستهلك 93% من مدى التفاوت، والمتوسط أعلى من منتصف المواصفة بمقدار 0.167.
