Practical AI for Your Team: Train Faster, Work Smarter with Derek Crager

In the latest episode of MetaPod, host Ron Crabtree and guest Derek Crager dive into one of the most pressing challenges in modern manufacturing: the skilled trades labor shortage. Derek offers a wealth of experience and a practical roadmap for solving this longstanding issue with a little help from artificial intelligence. 

Diagnosing the Skilled Trades Dilemma

For over 30 years, industries across North America have grappled with a shortage of skilled tradespeople – the professionals responsible for keeping critical operations running smoothly. Derek, whose career spans industrial construction, automotive, and food manufacturing, shares how this issue has only become more complex with time.

At Amazon, Derek led the development of the company’s highest-rated onboarding program for maintenance staff, achieving an unprecedented 92 Net Promoter Score (NPS). That program not only improved employee satisfaction but saved Amazon over $150 million annually by reducing turnover, which is proof that investing in training and retention pays off. 

Ron and Derek discuss how identifying weak points, such as knowledge gaps and burnout among top performers, is a vital first step. Questions to ask include:

• Do operations stall when one key person is missing?
• Are new hires taking too long to contribute?
• Is there a plan in place to transfer tribal knowledge before seasoned experts retire?

The Role of AI in Bridging Knowledge Gaps

AI, especially voice-activated tools, can empower, not replace, skilled tradespeople. Derek emphasizes that AI will never replace the human touch required to physically fix equipment, but it can record and deliver expert knowledge in real time. 

Using voice AI, companies can:

• Capture walkthroughs and troubleshooting steps from veteran technicians.
• Create hands-free access to training materials during live operations.
• Address knowledge gaps that cause unplanned downtime (up to 18% in some cases).

By recording tribal knowledge via simple voice interfaces, organizations avoid the scenario where one person knows everything, and that knowledge leaves with them. Derek offers real-life examples, including how a retiring electrician documented all machine reset procedures through a phone call, preserving years of experience for future workers.

Scaling Expertise Without Breaking the Bank

While augmented reality (AR) gets much of the spotlight, Derek makes a compelling case for simpler, more scalable AI solutions. His company, Practical AI, developed Pocket Mentor, a hands-free, screen-free tool that delivers expert guidance through voice interaction. Workers simply scan a QR code tied to a machine, tap their earbuds, and access tailored instruction. No app, no Wi-Fi, and no IT headaches. 

This approach allows:

• 24/7 access to expert knowledge across all shifts and locations
• Smart repetition of training for better retention
• Cost-effective scaling compared to AR or traditional training programs

The Bottom Line: Retention, Readiness, and Respect

AI doesn’t just solve operational inefficiencies; it improves worker experience. Derek notes that money is rarely the top reason people stay in skilled trade jobs. Respect, accomplishment, and confidence matter more. Tools like Pocket Mentor help employees feel empowered and supported, making them more likely to stick around.
