The agile principle of Avoid Waste dictates that teams should stop work on an initiative once the desired outcome has been achieved and additional effort would yield diminishing returns. In this scenario, the team met its specific target of 15% improvement. Continuing to work on that same initiative in hopes of achieving, for example, 16% or 17% might require significant resources that could be better used to address a different, higher-priority business need. By moving on to a new initiative, the team ensures they are maximizing the value delivered to the organization and not wasting time on " gold-plating " or over-engineering a solution that has already met its success criteria. This focus on efficiency and value-maximizing is a core component of the agile mindset, emphasizing that work not done is just as important as work completed.
