我曾在一家上市公司做Financial Controller,在Excel,会计流程和Financial Model方面有一定的积累。现和几个志同道合的小伙伴成立了一个培训咨询公司,主要从事BI与财务模型的研究。
我现在斗胆在足迹开贴,利用闲暇时间解答Excel 和Financial Model问题,希望能帮助想提高excel技术或者想往财务模型发展的朋友,也希望借此贴多认识一些在这个领域的大拿们。
TZ们的反映很热烈啊, 我先来抛个砖引个玉啥的。
同学们,你们在工作时是如何避免financial model (或一个简单的spreadsheet)中的错误呢?
I think that the accuracy of data should rely on model design, not on person, because people can’t always be attention to detail. A good model design should follow some rules.
First of all, we need to keep clear notes & documentation about the model’s assumptions and methodology. As we all know, “Garbage in, garbage out”. We need to protect ourselves by noting down the resource of all assumptions.
Secondary, we need to make sure that model has clear structure. A typical model should have three parts: data input, calculation and output. All these three parts should be separate.
Thirdly, we need to make sure the formulas in one area should be consistent, and avoid hard-coding in the formula.
Fourthly, we need to build error-check modules in model. When we set up error-check modules, we also need to consider the allowing tolerance of error. (这一点 原来TZ和990314 TZ在回贴中也提到了)
Last but not least, we need to do sense-checking about the model, make sure the result is reasonable. We can also get someone else check for us.
不好意思,还要上班,陪女儿,所以每天只能写一点。
