Solution:In the S-O-B-C model of organizational behaviour, the letter 'S' stands for Stimulus. This model, which is a conceptual framework used to understand and analyze human behaviour within organizations, includes four elements: Stimulus, Organism, Behaviour, and Consequences.
The Stimulus refers to an external event or environment that impacts the individual. It acts as a trigger or catalyst for a behavioural response, initiating the process that leads to observable actions or responses.
This model is instrumental in understanding how various external stimuli, such as workplace conditions, management actions, or broader organizational changes, influence employee behaviour, thereby affecting organizational performance and culture.
