Method Lab · Coursework in Practice
The Method, as the coursework lands.
Fenwick is currently completing an Executive MBA at Texas A&M University's Mays Business School. The Aperture Method is revised as each course lands: not as notes, but as working tools and analysis on this site. This is the running log, newest first.

InsightsAnalyticsAtlasThe statistics behind the analysis: regression on what moves sales (weather, holidays, drive time, demographics), scenario and sensitivity testing in the Profit Map, and confidence intervals rather than guesses.
- A weekly sales model (ordinary least squares) controlling for trend, season, holidays, marketing and a competitor opening
- Partial-effect plots for rain and temperature, including a curved fit that finds the temperature where sales peak
- An event study of holiday lift, week by week, with 95% confidence intervals
- A cross-sectional model across trade-area hexes: standardised betas for drive time, income, demographics, new housing and competition
- Plain-English explainers on every chart: what it shows, how to read it, why it matters

InsightsAnalyticsThe Profit Map and the Financial Analysis Workbench: financial statements read the way an analyst reads them, ratio and earnings-quality analysis, and cash conversion.
- The Financial Analysis Workbench: from a set of statements to a full written analysis, with an evidence grade on every add-back
- Two complete worked examples published free: a listed retailer and an owner-managed fabricator, because the analysis has to change when the entity does
- Ratio and DuPont analysis, an earnings-quality page (special items, impairments, non-GAAP) and a credit analysis step
- A 10-K annotator that ties every footnote back to the figure it explains
Next course: added here when its work lands.
How to read this

Each course is credited where its work shows up: a quiet line on the product page, a tag in the menu, and the curriculum map on the Method page. The analysis on those pages uses illustrative data for a fictional client; the methods are real.
