In the classical project management method (waterfall), a change in the requirement therefore usually inevitably leads to higher costs and/or longer project duration. When using agile project management methods (e.g. SCRUM), necessary changes and adjustments are integrated into the project cycle right from the start.
Teams work interdisciplinary and cross-functional. ‘Silo’ thinking (areas) takes a back seat. This supports the process to find a solution, helps to contain costs, to keep to the schedule and to generate a usable product as early as possible. This is exactly the goal of agile project management. ‘Agility’ in the sense of ‘flexible’ and ‘responsive’ therefore refers to the ability of teams to react to unforeseen changes in project requirements and to develop solutions.
