Adaptability is how responsive a project solution is. Can the job strategy speedily react to improvements through the challenge? If we're talking about changing necessities, waterfall will not be adaptable. In fact, waterfall will pressure the undertaking group to start out the undertaking more than if a need alter is found out late. Agile solutions are very adaptable to changing demands since the venture assessments and validates the necessities at each individual sprint throughout the project.
