Operating Models: How Nonprofits Get from Strategy to

These parameters essentially serve as criteria for evaluating operating model design alternatives. When a leadership team aligns around the design parameters before moving onto the specifics of operating model design, we find that difficult choices becomes easier as the parameters bring some objectivity into the process.

Parameter Wikipedia

A parameter (from the Ancient Greek παρά, para: "beside", "subsidiary"; and μέτρον, metron: "measure"), generally, is any characteristic that can help in defining or classifying a particular system (meaning an event, project, object, situation, etc.). That is, a parameter is an element of a system that is useful, or critical, when identifying the system, or when evaluating its

Diode modelling Wikipedia

Large-signal modelling Shockley diode model. The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (−), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few,typically 10 −12 A).
