In order to evaluate the effectiveness of your process, you must gather some information to evaluate. Let's say, for example, that you intend to decrease the number of accidents in a particular part of your process. To start with, you would need to have the data available of the number of accidents for this process function. In order to have this data available, capturing this data must become part of the process. The data can then be plugged into your control chart spreadsheet to be analyzed by a function or macro. After analyzing the data with a control chart, you will then be able to determine whether or not the process change was effective or not, or if the process is staying close to a specified target.

If you are not familiar with statistics or Six Sigma, then you should get training first. You should also get training in the tool, such as the spreadsheet application, if you are unfamiliar with it. There are many different types of control charts. Depending on the type of analysis being done, a different type of control chart can be used. Some of the types of charts include:
