Theoretical Foundations - Equity Theory and Expectancy Theory

Covering Assessment Criterion 1.2 of 5HR03, this video examines two foundational motivation theories that underpin reward strategy design: Equity Theory, developed by John Stacey Adams, and Expectancy Theory, primarily associated with Victor Vroom. Both theories are treated as analytical tools for understanding why reward approaches succeed or fall short in driving employee contribution and sustained organisational performance. The video positions these frameworks as essential reference points for HR professionals making decisions about compensation, recognition and performance-linked pay.

The Equity Theory section centres on Adams's concept of the input-to-outcome ratio and the role of social comparison in shaping employee perceptions of fairness. The video addresses the psychological and behavioural responses that arise when perceived inequity exists, including changes to effort, cognitive distortion and turnover, and considers the relationship between absolute reward value and perceived fairness. Practical implications around internal equity, external market benchmarking, transparent reward criteria and consistent communication are all covered in connection with the theory.

The Expectancy Theory section unpacks Vroom's three-component model — Expectancy, Instrumentality and Valence — and examines how the interaction between these components determines whether a reward system will motivate. The video gives particular attention to the concept of line of sight: the degree to which employees can trace a credible connection between their individual effort, measurable performance outcomes and the rewards that follow. Clear performance definitions, measurable indicators, differentiated reward levels and timely feedback are all discussed as factors that strengthen or weaken that connection, directly linking the theory to the AC 1.2 focus on extrinsic and intrinsic reward contribution.
