Trait theory and Behavioural theory of leadership.

Job satisfaction is an inner feeling; it is influenced by various organisational and personal variables.

The principles of organisation are guidelines for planning an efficient organisation structure.
c) Personality development takes place in various stages and a host of factors influence the development.

Organisational culture is described as the set of important understandings, such as norms, values, attitudes, and beliefs, shared by organisational members.

Explain individual perspective, group perspective, organisational perspective, and integrative perspective of OB.
b) Job design encompasses a number of factors: organisational context factors, task factors, job context and content factors, and employee factors.’ Discuss with examples.
