Discussion Question- Tools and Techniques

There are a variety of tools and techniques used to monitor, control and report the progress of a project. There are typically points in the project where a project health review is conducted to form a confidence level of the project completing as planned. If your project is more concerned about schedule vs. cost, what tools and/or techniques would be most valuable in determining your project’s health? Provide an example to illustrate your point. 

The attachment provided are a couple of example that some of my classmate did for this discussion. I added an examples because in case if the question did not make any sense (it didnt make any sense to me).
