Internal forces for change are factors within an organization that prompt it to adapt or change its processes, structures, or culture. In this context, internal forces are usually controllable by the organization, unlike external forces. Let's examine the options:
(A) Changing customer preferences - This is an external force, as it originates outside of the organization and is about the changing demands or tastes of consumers.
(B) International competition - This is also an external force. It originates outside the organization as the business competes with other companies in global markets.
(C) Demographic changes - These are external factors, as they relate to changes in the population's characteristics and do not originate within the organization.
(D) Participation/suggestions by employees - This is an internal force. Employees working within the organization often have insights and suggestions for improving processes, which can drive change from within.
(E) Mergers and acquisitions - While these actions involve external parties, the decision to merge with or acquire another company is considered an internal strategic decision, although it may be influenced by external opportunities.
The correct answer is (D) Participation/suggestions by employees, as this option involves internal contributions by the organization's workforce.
