Methodology defines the principles and framework used to select, combine, apply, and evaluate methods within a field.
It explains why specific approaches suit a task. Moreover, it provides rules for their consistent use.
A method describes a structured way to achieve an objective. In contrast, methodology examines and organizes several methods. For example, requirements engineering may combine interviews, modeling, prototyping, prioritization, and reviews.
Teams select suitable approaches according to goals, risks, constraints, and available skills. Therefore, safety-critical projects may require formal reviews and detailed documentation. Meanwhile, agile projects may focus on short feedback cycles and iterative delivery.
The selected framework should remain adaptable. In addition, teams should evaluate results and improve their approach when the project context changes.
A clear methodological framework supports informed method selection, consistent processes, traceable decisions, and reliable results.
