It should be noted that methodology is frequently used when method would be more accurate. For example, "Since students were not available to complete the survey about academic success, we changed our methodology and gathered data from instructors instead". In this instance the methodology (gathering data via surveys, and the assumption that this produces accurate results) did not change, but the method (asking teachers instead of students) did.
Methodology refers to more than a simple set of methods; rather it refers to the rationale and the philosophical assumptions that underlie a particular study. This is why scholarly literature often includes a section on the methodology of the researchers. This section does more than outline the researchers’ methods (as in, “We conducted a survey of 50 people over a two-week period and subjected the results to statistical analysis”, etc.); it might explain what the researchers’ ontological or epistemological views are. (See ontology, epistemology)
Another key (though arguably imprecise) usage for methodology does not refer to research or to the specific analysis techniques. This often refers to anything and everything that can be encapsulated for a discipline or a series of processes, activities and tasks. Examples of this are found in software development, project management and business process fields. This use of the term is typified by the outline who, what, where, when & why. In the documentation of the processes that make up the discipline, that is being supported by "this" methodology, that is where we would find the "methods" or processes. The processes themselves are only part of the methodology along with the identification and usage of the standards, policies, rules, etc.
