7 Proven Strategies to Protect Your Supply Chain

7 Proven Strategies to Protect Your Supply Chain

By Wayne Miller and Michael Keer

Reduce Risk and Prepare for the Unexpected

In today’s global economy, supply chain disruptions are inevitable. Companies must proactively plan for resilience and adaptability, whether due to geopolitical tensions, tariffs, component shortages, or factory challenges.

Product Realization Group’s veteran hardware and operations experts Michael Keer, Founder and Managing Partner, and Wayne Miller, New Product Development and Introduction, shared their insights on mitigating supply chain risk, drawing from decades of experience in manufacturing, operations, and supplier management. Below, we outline seven key strategies to safeguard your supply chain and keep your production on track.

Progress in USAF Engine Logistics?

Progress in USAF Engine Logistics?

I learned actuarial methods for forecasting and spares planning while working for the US Air Force Logistics Command in the 1970s [AFLCM 66-17 and AFM 400-1]. I am grateful for the education, and I am sorry to report that the USAF has reverted to MTBF management.

The US AFLC actuarial methods were developed for engine management in the 1960s by RAND Corp. [Giesler]  They estimated age-interval failure rates and made actuarial forecasts of engine demands depending on the flying-hour program plan. An actuarial forecast is ∑a(s)n(t-s), s=1,2,…,t, where a(s) is actuarial failure rate conditional on survival to age s and n(t-s) is the installed base of age t-s. Periodic meetings consolidated engine lifetime and failure data into agreements on actuarial failure rates, for forecasting engine demands and for war readiness spares requirements.

The USAF actuarial methods assume constant failure rates within short age intervals, Poisson demands, and ignore variance induced by variable flying hours per aircraft in the flying hour program. I later figured out how to estimate actuarial failure rates for all engines, major modules, and their service parts, with or without life-limits and without lifetime data; I computed the distribution of demand forecasts, not Poisson. I offered to show AFIT faculty, AFOSR, AFRL, and RAND how to extend actuarial methods to all service parts [George, 1993].

The Paradox of the Invisible Discipline

The Paradox of the Invisible Discipline

Early in my quality management career, while working at a small extrusion and fabrication company, I learned something important: bosses pay attention to the money. And if I focused on cost savings projects, I could stay on their good side.

Most of my cost savings efforts at that time focused on eliminating specific types of defects. After all, even a low-frequency defect—especially one that reaches a customer—can drive substantial savings once resolved. Other projects looked inward, targeting inefficiencies in our systems and practices. Lab procedures, control plans, and audit schedules tend to drift out of sync with the products and processes they’re supposed to control. So every now and then, a little system hygiene—an organized cleanup—can free up resources and allow you to reallocate attention to where it’s needed most.

It was during one of those hygiene projects that I stumbled into something I’ve since come to call The Paradox of Invisible Discipline.

Statistical Tolerance Stack-up

Statistical Tolerance Stack-up

Dear friends, we are happy to release this 85th video in our channel ‘Institute of Quality and Reliability’! In this video, Hemant Urdhwareshe has explained the concept of statistical tolerancing tolerance stack-up! Conventional Extreme Value Analysis (EVA) can result in increased manufacturing costs! Statistical tolerancing is more optimistic method of analysing tolerances and can reduce manufacturing costs! Concepts of loop diagram, additivity of variances are also explained briefly in the video with a practical application case study of tolerance stack-up analysis.

By Mike Freier

The Journey to Volume Manufacturing and Beyond: Scaling Your Hardware-based Product

In the span of our idea-to-scale series, we’ve navigated through the various phases of transforming a hardware-based product idea into a market-ready product. We’ve explored the crucial stages of design, planning, development, as well as controlled introduction. Now, we arrive at the pivotal point of Volume Manufacturing, where we will learn how it can be leveraged to increase efficiency, improve quality and lower costs to effectively scale your business. 

In this final segment, we turn our focus to scaling a resilient supply chain and revisiting key concepts from earlier segments. These include Contract Manufacturer (CM) selection, tooling and fixturing, communication, and business systems. We’ll also include additional insights into production forecasting, test, and logistics and repair, with a focus on quality, delivery and cost-effectiveness.

The Fixed Capability Technique

The Fixed Capability Technique

A Practical SPC Method for High-Capability Processes

By Ray Harkins and Michael J. Vella

Manufacturing professionals who regularly apply Statistical Process Control (SPC) methods, such as X̄ and R charts, know the power of SPC to maintain control of both quality and cost. The standard practice emphasizes attention to variation, with operators trained to take corrective action whenever a process signals an out-of-control condition. Typically, this means adjusting a process input, verifying the correction, and resuming production.

However, not every out-of-control signal requires intervention, especially in processes where inherent variation is extremely small and product quality is consistently high. In some cases, such as tooling wear or small material variations, process center shifts may occur outside of the operator’s ability to correct. Responding to these shifts with standard SPC rules can lead to overcorrection, lost productivity, and increased variation.

Quality Objective 6: TECHNICAL RISK ANALYSIS

“Risk analysis is the art of turning uncertainty into actionable insight.” — Anonymous

In this article, I will outline how to evaluate an FMEA against the FMEA Quality Objective for Technical Risk Analysis.

By definition, “risk analysis” is “the systematic process of identifying, evaluating, and estimating the levels of risk involved in a situation, process, or system, in order to inform decision-making. [Read more…]

What is Acceptance Sampling?

What is Acceptance Sampling?

In manufacturing and quality assurance, we rarely have the time—or budget—to inspect every single part in a batch. That’s where acceptance sampling comes in. It’s a statistical tool that helps us decide whether to accept or reject a lot of material based on a random sample. But more than just a shortcut, acceptance sampling is a structured decision-making process that balances quality expectations with efficiency and risk.
