Product software implementation method result in ambiguity when questions arise in the execution of the implementation process. On the other hand methods can be used as a profession, meaning that the method should be taken strict and the usage of the method should be a profession, instead of a guiding principle. This view is very useful if the implementation process is very complex and is very dependent on exact and precise acting. Organizational and quality management will embrace this view, as a strict usage of any method results in more clarity on organizational level. Change management however might indicate that more flexibility in an
Numerov's method Numerov's method Numerov's method (also called Cowell's method) is a numerical method to solve ordinary differential equations of second order in which the first-order term does not appear. It is a fourth-order linear multistep method. The method is implicit, but can be made explicit if the differential equation is linear. Numerov's method was developed by the Russian astronomer Boris Vasil'evich Numerov. The Numerov method can be used to solve differential equations of the form In it, three values of formula_2 taken at three equidistant points formula_3 are related as follows: where formula_5, formula_6, formula_7, and formula_8. For nonlinear equations of
