The expression "Process Driven" means having the ability to perform a kind of work independently by following an associated process strictly and persistently. This ability requires doing the work in a consecutive manner, without skipping, adding or modifies steps and also without a need for external control.
For example, an employee who has the ability of being process-driven will do his/her job explicitly and step by step, without direct involvement of the supervisor. Such an employee is focused on the process rather than on results. This individual appears to be self-sufficient, who can do the job uninterruptedly or with minimized number of breaks.
Another example: a process-driven organization is the one that tends to achieve its strategic business objectives by managing its activities as processes which have accurate and finite data including inputs, resources and outputs. The organization estimates available resources, identifies needed inputs and determines a process flow that describes how the activities need to consume resources to transform inputs into outputs.
