We tell clients up front that our first estimate will be based on an understanding of the coarse-grained business requirements and technical architecture.
我们预先告诉客户我们的第一次评估是基于对粗粒度业务需求和技术架构的理解。
The coarse-grained estimate reflects an initial understanding of the scope and effort.
粗粒度评估反映了对范围和成果的原始理解。
Because the initial estimate is so coarse-grained, a fair amount of wiggle room exists to handle emergent design, refactoring, and other technical-hygiene activities.
因为最初评估是粗粒度的，还有很大的回旋空间，可以处理紧急设计、代码重构、以及其他技术清洁活动。
