7001-11 Reliability, Availability, and Maintainability (RAM)

Overview:

Introduction

Reliability, Availability, and Maintainability (RAM) focuses on actions in order to help attendees enhance the performance of material systems. RAM provides extensive processes and techniques to study and manage the total Life Cycle Costs of an asset to boost cost efficiency. Underlines ‘design for RAM’ and ‘RAM verification’ activities to provide the viewpoints of the producer and customer.
