The Kasavana-Smith Menu Engineering Model

Menu engineering was formalized by professors Michael Kasavana and Donald Smith at Michigan State University in the 1980s. The model uses a simple but powerful two-axis framework: each menu item is evaluated on its contribution margin (selling price minus food cost) and its popularity (share of total items sold).

The genius of this approach is that it reveals items that look profitable in isolation but actually drag down your blended margins when you factor in how often they sell. A $12.99 burger with a $3.50 food cost looks great on paper, but if it accounts for 35% of sales while your $4.99 side with a $0.45 food cost only sells 5% of the time, your menu is underperforming. Menu engineering quantifies these dynamics and tells you exactly where to intervene.

Understanding the Four Quadrants

Stars are your best performers: high contribution margin and high popularity. Protect these items. Keep quality consistent, position them prominently on your menu board or app, and resist the urge to discount them. Small price increases (tested quarterly) often stick without volume impact.

Plowhorsesare popular but low-margin. In QSR, these are often core entrees priced competitively to drive traffic. The fix is never to remove them. Instead, work the cost side: renegotiate supplier pricing, adjust portions by small amounts guests won't notice, or substitute one ingredient. Even $0.10 off food cost on a Plowhorse selling 400 units a week saves $2,000+ annually per location.

Puzzlesare profitable when they sell, but they don't sell enough. Common fixes: better menu placement (eye-level on menu boards, featured in app), staff training to suggest them, better names and descriptions, or limited-time features that create urgency. If a Puzzle item has been promoted multiple times and still does not sell, consider whether it belongs on your menu at all.

Dogsare low-margin and low-popularity. These are candidates for removal. However, some Dogs serve strategic purposes: a kid's meal might be a Dog but it brings in families who spend heavily on other items. Before removing a Dog, check whether it's an anchor item that drives group visits. If it's not, replace it with a new item that fills a menu gap.

Menu Engineering for Multi-Unit QSR Operators

Multi-unit operators should run menu engineering at both the system level and the location level. System-level analysis reveals which items perform across the brand. Location-level analysis catches regional differences: a Puzzle item in suburban locations might be a Star in urban stores due to different customer demographics.

The financial impact of menu engineering scales with unit count. A $0.15 food cost reduction on a Plowhorse selling 300 units per week generates $2,340 in annual savings per location. Across 50 locations, that single ingredient substitution is worth $117,000 per year. Multiply that across 3-4 Plowhorse items and the analysis pays for itself many times over.
