في عالم ضمان الجودة ومراقبة الجودة (QA/QC)، غالبًا ما يكون التركيز على ضمان الجودة الأولية للمنتجات والخدمات. ومع ذلك، هناك جانب آخر حاسم يستحق نفس القدر من الاهتمام: **الصيانة**. **ضمان جودة الصيانة (MQA)** يلعب دورًا حاسمًا في ضمان بقاء المنتجات والمعدات والأنظمة تعمل بشكل صحيح وآمن طوال عمرها الإفتراضي.
**ما هو ضمان جودة الصيانة؟**
MQA هو نهج منهجي لضمان أن **أنشطة الصيانة** – التي تشمل مهام مثل الإصلاحات، والإصلاحات الشاملة، وإعادة البناء، والتعديلات، والاستصلاح – **تتوافق مع المتطلبات الفنية المحددة**. الأمر يتعلق بضمان عمل الأصل المُحافظ عليه كما هو مُصمم، ولقاء معايير الأداء، والالتزام بلوائح السلامة.
**لماذا يُعد MQA مهمًا؟**
**العناصر الرئيسية لـ MQA:**
**MQA في العمل:**
تُطبق مبادئ MQA عبر العديد من الصناعات، بما في ذلك:
**الاستنتاج:**
يُعد MQA عنصرًا أساسيًا من عناصر ضمان الجودة الشاملة، ويلعب دورًا حيويًا في ضمان موثوقية الأصول وسلامتها وأدائها على المدى الطويل. من خلال دمج MQA في عملياتها، يمكن للمنظمات تقليل التكاليف، وتعزيز الكفاءة، والحفاظ على سمعة قوية لتقديم منتجات وخدمات عالية الجودة.
