Drift or Step Response Change
Jagdish B Acharya, Consultant, India, Premium Member
In electronic control systems we learn about two types of changes:
- Drift is a gradual change which happens due to small effects of many factors.
- Step response is a major change that happens due to step change signal.
This concept applies to all types of changes. We often look at one type of change and get contradictory reasons or agents of change. It is not easy to recognise in social, cultural or institution cases to recognize if the change is drift or step response.
The controlling mechanism governing these can be called as regulation and control. Regulation applies as per societal rules and understandings and control applies due to authoritarian influence. We may view governmental influence as controlling and market influences as regulating.
