Transition state theory explains the dynamics of reactions. The theory is based on the idea that there is an equilibrium between the activated complex and reactant molecules. The theory incorporates concepts from collision theory, which states that for a reaction to occur, reacting molecules must collide with a minimum energy and correct ...
Even though the theory is widely applicable, it does have limitations. For example, when applied to each elementary step of a multi-step reaction, the theory assumes that each intermediate is long-lived enough to reach a Boltzmann distribution of energies before continuing to the next step. When the intermediates are very short-lived, TST fails ...
John P. Kotter, a pioneer of change management, invented the 8-Step Process for Leading Change. John P. Kotter, the Konosuke Matsushita Professor of Leadership, Emeritus, at the Harvard Business School is considered the most influential expert of change management. [29] He invented the 8-Step Process for Leading Change. It consists of eight stages:
People developing their theory of change in a workshop. A theory of change (ToC) is an explicit theory of how and why it is thought that a social policy or program activities lead to outcomes and impacts. [1] ToCs are used in the design of programs and program evaluation (particularly theory-driven evaluation), across a range of policy areas.
The equation follows from the transition state theory, also known as activated-complex theory. If one assumes a constant enthalpy of activation and constant entropy of activation, the Eyring equation is similar to the empirical Arrhenius equation , despite the Arrhenius equation being empirical and the Eyring equation based on statistical ...
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.

Sequential function chart (SFC) is a visual programming language used for programmable logic controllers (PLCs). It is one of the five languages defined by IEC 61131-3 standard. The SFC standard is defined as Preparation of function charts for control systems , and was based on GRAFCET [ fr ] (itself based on binary Petri nets [ 1 ] [ 2 ] ).
