Forces driving the need for major organizational change include increased competition, both domestic and international, as well as global changes in markets, technology, and economic integration. There are two main types of change - incremental, which involves continuous progression and product improvements, and radical change, which requires transforming the entire organization. Successful change involves ideas and identifying needs, adopting and implementing changes, and allocating necessary resources. Barriers to change can include excessive focus on costs, failure to perceive benefits, and resistance to change.
