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
Sidi's generalized secant method is the next approximation formula_17. Muller does this for the case "k" = 2 but no such prescriptions appear to exist for "k" > 2. Sidi's generalized secant method Sidi's generalized secant method is a root-finding algorithm, that is, a numerical method for solving equations of the form formula_1 . The method was published by Avram Sidi. The method is a generalization of the secant method. Like the secant method, it is an iterative method which requires one evaluation of formula_2 in each iteration and no derivatives of formula_2. The method can converge much faster though, with an order which
