Viable means capable of independent existence and implies both maintaining internal stability and adaptation to a changing environment. "Internal stability" and "adaptation" can be in conflict, particularly if the relevant environment is changing rapidly, so the viable system model (VSM) is about maintaining a balance between the two such that the system is able to survive.
The Change Management Foundation is shaped like a pyramid with project management managing technical aspects and people implementing change at the base and leadership setting the direction at the top. The Change Management Model consists of four stages: Determine Need for Change; Prepare & Plan for Change; Implement the Change; Sustain the Change
Key critics of the command-and-control management ethos and techniques include members of the systems-thinking community and associated thinkers, including W. Edwards Deming, [1] John Seddon, [2] Kōnosuke Matsushita, [3] Taiichi Ohno, Russell L. Ackoff, [4] Donella Meadows, [5] Alfie Kohn, [6] and the outspoken Vanguard Method practitioner ...
Input-to-state stability of the systems based on time-invariant ordinary differential equations is a quite developed theory, see a recent monograph. [6] However, ISS theory of other classes of systems is also being investigated for time-variant ODE systems [ 20 ] and hybrid systems .
In systems theory, a system or a process is in a steady state if the variables (called state variables) which define the behavior of the system or the process are unchanging in time. In continuous time , this means that for those properties p of the system, the partial derivative with respect to time is zero and remains so:
In mathematics, stability theory addresses the stability of solutions of differential equations and of trajectories of dynamical systems under small perturbations of initial conditions. The heat equation , for example, is a stable partial differential equation because small perturbations of initial data lead to small variations in temperature ...
This was the start of the theory of robust control, which took shape in the 1980s and 1990s and is still active today. In contrast with an adaptive control policy, a robust control policy is static, rather than adapting to measurements of variations, the controller is designed to work assuming that certain variables will be unknown but bounded.
Complexity theory emphasizes interactions and the accompanying feedback loops that constantly change systems. While it proposes that systems are unpredictable, they are also constrained by order-generating rules. [6]: 74 Complexity theory has been used in the fields of strategic management and organizational studies.
