Positional Advantage

Day and Wensley framed competitive advantage as a cycle: sources of advantage (superior skills and resources) yield positional advantages (superior customer value or lower relative cost) that produce performance outcomes, which are reinvested in the sources. Assessment, they argued, needs both competitor-centered and customer-focused measures. It is the bridge between Porter's positions and the resource-based view, written for marketing before either camp had claimed the field.

Second cell in a column with no block drift. Alderson named differential advantage; Day and Wensley gave it a diagnostic. Every later cell in the column (capabilities, adaptive capabilities, excellence) is a refinement of their "sources" box.

Six curated links out, second only to Market Orientation: Resource-Advantage Theory, Customer Value, Brand Equity, Enviropreneurial Marketing, Market-Based Assets, and Sustained MO Advantage. Eleven deep-dive mentions in ten more places, from the value chain and logistics capabilities to export venture performance and corporate environmentalism.

Two curated links in, from opposite ends of the table: Competitive Positioning (column 1; Porter's positions restated as outcomes of skills and resources) and Market Share Effect (column 18; PIMS measures as the performance side of the cycle). Its reference list reaches back to Smith (1956) on segmentation, Abell (1980), and Jacobson and Aaker (1985).

27 anchor works in 11 families cite it; 11 Core cells hold one. Its descendants are the 1990s: Market Orientation (both 1990 anchors), Resource-Advantage Theory (Hunt and Morgan, 1995), Learning Orientation (Slater and Narver, 1995), Innovativeness (Han, Kim, and Srivastava, 1998), then Marketing Capabilities (2005), Sustained MO Advantage (2011), Brand-Customer Asset Link (2012), CMO and Marketing Power (2015), and Marketing Excellence (2020).
