In most real projects, running a sequence of smaller DOEs yields more knowledge per run and carries far less risk than committing everything to one large design upfront. You learn from each stage, adjust your assumptions, and spend resources where they matter most. That is the core logic behind a sequential DOE strategy, and [...]

The wooden catapult is a signature Air Academy Associates teaching tool because it compresses complex DOE concepts into a tangible, memorable exercise. Instead of watching slides about factorial designs and interaction plots, learners physically launch a ball, record distances, and immediately see what the data is telling them. In this article, we'll unpack how [...]

You are about to complete a full fractional factorial DOE workflow in Excel using DOE Pro XL, from design creation through analysis and factor recommendations. This guide assumes you already understand DOE fundamentals and have chosen DOE Pro XL as your Excel-native screening tool. In this article, we walk through each step with menu [...]

Structured Design of Experiments (DOE) has helped MRO shops cut engine overhaul turnaround time (TAT) by 20–40% in documented case studies. These results did not come from guesswork—they came from disciplined, statistically sound experimentation applied directly on the shop floor. In this article, we break down exactly how MRO teams design and run experiments [...]

Digital marketers run hundreds of A/B tests each year, yet many declare a winner without confirming statistical significance or isolating the true drivers of conversion lift. When you treat an A/B test as a formal DOE, you move beyond guesswork and build a repeatable system for data-driven decisions that deliver measurable business outcomes. This [...]

Design of Experiments (DOE) serves as the statistical backbone of the Six Sigma Black Belt methodology, transforming complex process optimization from guesswork into precise scientific investigation. Professionals who want structured support can explore Air Academy’s broader Design of Experiments training options for practical DOE learning. Six Sigma Black Belts leverage DOE to identify critical [...]
