这还是敏捷、迭代的方法的宗旨，表现出就风险、成本、质量，和效率而言，在瀑布模型上的重大改善。
It is also a tenet of an agile, iterative methodology, representing a significant improvement over waterfall in terms of risk, cost, quality, and efficiency.
瀑布模型经常被认为是更具预见性的，但是不幸的是，这种预见性往往只有在项目的后期阶段才会变成可能。
Waterfall is often touted as being more predictable, but unfortunately the prospect of achieving the predicted result often fails to emerge until the late stages of the project.
从多年尝试瀑布模型的经验中我们得出，我们很少能够事先预知所有的事，试图在一开始就做对是不完美的。
As we know from attempting to use waterfall methodologies for years, we rarely know everything up-front, and our attempts to get it right at first are imperfect.
项目通常是从分析设计开始，即使在开发团队不使用瀑布模型变体的情况下也是这样。
A project usually begins with analysis design, even if the development team isn't using a waterfall variant.
这里表现的是产品生命周期里稳定的“持续(sustaining)”阶段，处在带有流程的瀑布状态转换模型的管理之下。
What's happening here is a stable "sustaining" phase in a product's lifecycle, managed in a waterfall state transition model with a flow.
他仔细地看了一下像WinstonRoyce这样人的想法如何被误解了，以及Royce后来是如何由于将瀑布模型强行用于产业界而受到了不公正的惩罚。
He looked carefully at how the ideas of people like Winston Royce were misunderstood and how Royce was later unfairly chastised for foisting the waterfall model on the industry.
第2章为什么瀑布模型会失效？

ADDIE模型有不同的版本，但是，在本质上，它是一个瀑布式方法。
There are different versions of the ADDIE model, but, in spirit, it is a waterfall method.
RMC支持基于不同开发方法的过程，并可用于定义不同的生命周期模型，例如瀑布，递增，或迭代生命周期模型。
RMC supports processes based on different development approaches and can be used to define different lifecycle models such as waterfall, incremental, or iterative lifecycles.
如果您极端地追求重叠迭代技术，那么您会沿着瀑布模型。
If you pursue the technique of overlapping iterations to the extreme, you will end up at the waterfall model.
瀑布和螺旋模型在项目开始时声明前后关系和可交付定义。
Waterfall and Spiral methodologies set the context and deliverable definition at the start of a project.
然而，危害已经造成了，由于先入为主形成的习惯，瀑布模型思想已经根深蒂固、积习难改。
However, the damage was done, and a strong mindset with a bias toward Waterfall development had become ingrained.
