关于螺旋模型的问题 [英] question about spiral model

问题描述

在此模型中，所有活动均以螺旋形式组织

in this model all activites organized in spiral

Quadrant 1: Determine objectives, alternatives, and constraints.

Quadrant 2: Evaluate alternatives, identify, resolve risks.

Quadrant 3: Develop, verify, next-level product.

Quadrant 4: Plan next phases.

我的问题是关于象限4的下一阶段计划意味着什么?

My question is about Quadrant 4 what is plan next phases mean?

推荐答案

^ ]在一些语句中提供了很好的定义.

螺旋式开发模型具有所有模型共有的一个特征-需要在关键阶段或控制点进行高级技术规划和多学​​科审查.模型的每个周期最终都会进行技术审查，评估状态，进度，成熟度，迄今为止的开发工作的优点，风险；解决关键的运营和/或技术问题(COI/CTI)；并审查计划并确定螺旋式下一次迭代需要解决的COI/CTI."

基本上，您可以弄清楚上一阶段您做错了什么(当前的期限和可交付成果)，并最终计划下一步要做的事情.

This resource [^] provides an excellent definition of this in a few statements.

"The spiral development model has one characteristic that is common to all models - the need for advanced technical planning and multidisciplinary reviews at critical staging or control points. Each cycle of the model culminates with a technical review that assesses the status, progress, maturity, merits, risk, of development efforts to date; resolves critical operational and/or technical issues (COIs/CTIs); and reviews plans and identifies COIs/CTIs to be resolved for the next iteration of the spiral."

Basically, you can figure out what you did wrong in the previous phase, where you are at present (in terms of deadlines and deliverables) and finally plan what you need to do next.

为什么您认为它被称为螺旋模型吗? http://en.wikipedia.org/wiki/Spiral_model [

Why do you think it is called a Spiral model? http://en.wikipedia.org/wiki/Spiral_model[^]

As the name implies, this is not a four stage process - the fourth stage involves preparing to go back around to start again from Quadrant 1, having learnt from what you did last time. The idea is to iterate round the quadrants through the entire life of the project, rather than assuming that planning should stop when you release the first version.

Spiral模型是迭代的，请计划下一个阶段意味着准备再次更详细地执行步骤1-4.

The Spiral model is iterative, plan the next phase means make ready to go through steps 1-4 again with greater detail.
