Abstract
This paper is primarily based on a case study of a leading bank in Pakistan, that is, MCB Bank Ltd.

The study covers a change management aspect such as strategic intervention technique; a need for change management; resource implication; planning change; strategies in change management; system effectiveness; managing resistance to change; leadership issues; cultural issues; people issues; external environment issues; workable approach to overcome change resistance; appropriate model and implementing the model.
