Distinguish between accuracy and precision
Answers
Answer:
What does accuracy mean?
If a measurement is accurate, it means that it agrees closely with the accepted standard for that measurement. For example, if we estimate a project's size to x and the actual size of the finished project is equal to or very close to x, then it is accurate, but it might not be precise. The closer a system's measurements to the accepted value, the more accurate the system is considered to be.
Humans make errors all the time, but if you're using a project management software to help you scope, you will begin to have a more accurate project measurement and refined process.
What does precision mean?
A measurement that is precise means that it agrees with other measures of the same thing. In the sense of project scoping, let's take an estimation of workload as an example. If we estimate the size of several projects and they, in the end, are all close to or equal to what we predicted, then we can start to get a sense of the precision of our estimates. But first and foremost, each project needs to be as accurate as possible.
