当我不了解网站的所有功能时，如何估计网站的构建（刷新）？
我知道这里有几个估计问题，并且我已经阅读了其中的大部分问题，但这一个略有不同。 如果您要对网站进行刷新，则可能会包括可用性增强，从而增加页面制作和开发的时间。 我们永远不会在浏览网站时对自己说，它现在的样子就是未来的样子。 如果是这样的话，那么我们的客户就不会寻求我们的专业知识。 在回复 RFP 或创建正式的工作说明书之前，是否应该始终要求进行团队头脑风暴？ 如果进行头脑风暴的人没有完成最终工作怎么办？ 我们只能在一定程度上盘点当前站点，我开始认为我们应该只对我们所知道的进行估计，让潜在客户告诉我们哪里缺少某些元素。
I know there are several estimating questions here, and I have read through most of them, but this one is slightly different. If you're doing a refresh on a Web site, it might include usability enhancements that increase the hours for page production and development. We'll never look at a Web site and say to ourselves the way it is now is the way it will be in the future. If that were the case, then our clients wouldn't be looking for our expertise. Should it always be a requirement to do a team brainstorm before responding to an RFP or creating a formal statement of work? What if those doing the brainstorming are not doing the final work? We can only inventory the current site to a certain extent, and I'm starting to think we should make estimates only for what we know, letting the potential client tell us where we're missing certain elements.

在您的提案中，相当具体地说明您在当前网站上看到的内容（有多少页面/资源？它们是低/中/高复杂度吗？您看到的已经存在的高级功能是什么（即搜索、安全、AJAX、配置文件等）以及您会考虑添加什么？给出范围，而不是具体的估计，
您在不了解需求的情况下提供更多有关您所看到的内容的细节将有助于客户相信您不仅仅是通过 RFP 来提交提案。 ，并且你对工作很认真，而不是承诺比你能做的更多/更快地交付。 客户确实明白你无法真正做出可靠的估计，但他们越相信你已经做出了认真的决定。尝试越多，他们就越有可能投入时间来帮助您了解制定最终提案和 SOW 的要求。
In your proposal, be fairly specific about what you saw on the current web site (how many pages/resources? are they low/med/high complex? What are the high level features you see already existing (i.e. search, security, AJAX, profiles, etc.) and what would you consider adding? Give ranges, rather than specific estimates.
The more detail you give about what you saw without knowing the requirements will help the client believe you didn't just shoot the proposal through an RFP chute, and that you're serious about the work, without tying you to a commitment to deliver more/faster than you can. Clients do understand that you can't really make a reliable estimate, but the more they believe you have made a serious attempt, the more they're likely to commit their time to helping you understand the requirements towards making a final proposal and SOW.
当您不知道自己的估计值时，预计估计值会不准确（最多是近似值）。
陈述你的假设（“如果我们做 Foo，则 X；如果我们不做，则 Y”）。
说明您需要什么来减少不确定性（“我们需要花一个小时与客户一起收集要求，然后才能提供任何估计”）。
When you don't know what your estimating, expect the estimation to be inaccurate (and, at best, approximate).
State your assumptions ("X if we do Foo or Y if we don't").
State what you would need to reduce uncertainty ("we need to spend an hour with the client to gather requirements before we can provide any estimate").
