company also improved cycle time standard deviation by 49%, from 82 days down to 42 days. As a result, when normalized for a 10-week release timebox, feature throughput improved by 101% from 414 features delivered per release to 833 per release. In addition to producing more incremental value across the organization, the Scaled-Agile implementation was the catalyst for increased commitment completion percentages. The planned work completed during a program increment increased by 37%, from 60% in 2017 to 88% in 2019.
重组为发布火车后，虽然史诗(Epic)组合仍然存在，但史诗（Epic)的数量从2018年7月的275个缩减为2019年10月的37个，仅包含了大型解决方案（多发布火车）的举措。史诗通过少数领导者的不断梳理过程进行优先级排序，特性和团队级工作的所有权转移到发布火车上，最终目标是授权自给自足的发布火车,让它们能自主地价值交付。SAFe的实施基本上将整个组织的特性交付时间和可预测性提高了2倍：特性的周期时间减少了一半以上，从71天减少到33天。该公司还将周期时间的标准偏差提高了49%，从82天减少到42天。因此，在10周的发布时间盒下，特性的吞吐量提高了101%，从每次发布414个特性到每次发布833个。除了在整个组织内产生更多的增量价值外，SAFe的实施还促进了承诺完成率的提高。在一个项目群增量期间完成的计划工作增加了37%，从2017年的60%增加到2019年的88%。

1.客户营销发布火车的Scrum团队没有使用一致的工具和技术。所有这些团队需要以更好的方式和更高的速度把工作集成起来。
2.这些Scrum团队中有许多不同的专业角色。减少过多的专业角色的划分，将所有角色聚焦于交付价值，这样能够有更好的效果。
3.所有团队之间的沟通需要清晰、一致、更有成效。
4.需要进一步缩短团队从开发开工到交付价值的时间。
6 Root Cause Analysis 根本原因分析
Scaled Scrum enables a performance analysis of components of scaling frameworks using a heat map [21]. Each column represents an organization, and each row is a Scaled Scrum component. Green is great, and red is blocked. Figure 1 is a photo of the actual heatmap used by Client Marketing in their analysis of the items identified in this paper.
