Description
TICHY’S TECHNICAL POLITICAL CULTURAL (TPC) FRAMEWORK
Tichy offers an open system model of organisational change management, consisting of inputs (environment, history and resources), throughputs or change leavers (mission/strategy, tasks, people, processes and networks), and outputs (performance). The focal point is the output variable, performance, which is dependent on the effects of the input and throughput variables. These are considered to be interdependent, but some are considered to have stronger effects than others.
