Problems I've Helped Engineers Solve

Process Capability Analysis
Technical Challenge

The engineer needed to determine whether a manufacturing process met the company's Cpk and Ppk requirements.

During our session, we evaluated data normality, analyzed process capability, and identified potential sources of bias that could affect the interpretation of the results.

...
Measurement System Analysis (MSA / Gage R&R)
Technical Challenge

The goal was to demonstrate the repeatability and reproducibility of a CMM measurement system.

Together, we structured the study, reviewed variation sources, analyzed the results, and developed a technical report to support the MSA conclusions.

...
Design of Experiments (DOE)
Technical Challenge

A factorial DOE had already been completed, but the confirmation runs failed to reproduce the expected results.

We reviewed the experimental strategy and transitioned the analysis to a Response Surface DOE, allowing us to identify a more robust operating window.

...
Statistical Process Control (SPC)
Technical Challenge

While implementing an SPC system using X̄-R and I-MR control charts, the team was unsure how to establish reaction limits and what actions should be taken when those limits were exceeded.

We developed a reaction plan based on observed process variation and the tolerance requirements of the measured characteristic.

...
Technical Interview Preparation
Career Development

How do you explain a project you've implemented? Why are you looking for a new opportunity? What value can you bring to a company?

We worked together to structure responses around the engineer's actual experience, highlight relevant projects, and communicate results with greater clarity and impact.

...
Resume Optimization
Career Development

After three months of applying without receiving a single interview invitation, the engineer needed a new strategy.

We reviewed the resume, reorganized experience to align with the target role, and highlighted achievements and technical contributions that were most relevant to the position.

What Engineers Are Saying

Over the years, I've had the opportunity to work with engineers from different industries through training, technical consulting, and career coaching. Here are a few of their experiences.

Before taking the course, I only used Minitab to create basic charts. Now I can select the appropriate statistical tests, interpret results, and confidently justify my decisions during validation activities.

Mastering Minitab & Statistics for Validation

The combination of MSA and GD&T helped me better understand how measurement systems influence the interpretation of geometric tolerances. The training was practical and immediately applicable to my daily work.

MSA & GD&T

This course helped me understand how to apply statistical tools within medical device validation activities. The explanations were practical and focused on real industry requirements.
