Run charts trong luyện thi PMI-RMP PMP
A run chart shows a pattern or trends of variation over time. It also shows a history of declines and/or improvements within the process. The Run chart is nothing but a line graph that has data points plotted in the order of occurrence. It is used to monitor two main things:
- Technical Performance – Ex: How many defects were identified & fixed in a time-period
- Cost & Schedule Performance – Ex: Total no. of activities completed per time period without significant variances
Run charts are very useful in trend analysis which is a mathematical technique that is used to forecast the future outcome of the process based on historical information. These are extremely useful in risk analysis. Look at the sample run chart below:
Here we have plotted the number of times we had to perform an activity every month and seeing this we can safely say that trend here is improved performance and that the number of instances has steadily declined and is at a much lower level when compared to what it was at the beginning.
