Vibration program audits are based on the best selling book: Audit it. Improve it! Getting the most from your vibration monitoring program – by Alan Friedman. This book is a must read for anyone involved in vibration analysis, condition monitoring or condition based maintenance. Buy it on Amazon: Audit it Improve it

For 15 years, I visited 100’s of clients worldwide to help install and support vibration monitoring programs as a senior engineer at DLI Engineering (now Azima). This gave me deep insight into what is required to run a successful condition monitoring program. Connect to Alan on LinkedN:

While at DLI, I produced and taught Category I, II and III equivalent vibration analysis courses to hundreds of students worldwide (in English and Spanish) and I contributed in the development of DLI’s automated diagnostic system. Over the years, I have published a number of technical articles in a wide array of industry publications and I have presented my papers at trade shows.

I have been a senior instructor for the Mobius Institute providing vibration training to well over 1,000 students since 2007. I’ve trained students at ISO 18436-2 Category 1, 2, 3 and 4 in public and on-site courses conducted all over the world. I also trained many of Mobius trainers and created much of their training materials.
