Prior to any significant analysis, we developed a ROM that the project would cost $1.5M. However, as we developed the WBS and were able to put cost estimates to each work package, the definitive estimate was $1.375M. ROM estimates are used very early in the project when there is a lack of detailed information. Definitive estimates occur when there are accurate estimates at the work package or activity level. See all posts in our PMP Concepts Learning Series.
Water seeks its own level simply means quality people of integrity find other quality people of integrity and vice versa. It also means high quality finds high quality and low quality finds low quality. This is true in business and in life. It is a scientific fact: water does indeed reach its own level. Itâs also a scientific fact that our bodies are made of 90 percent water. And the Bible says the same thing but like this:âLet the waters under the heavens be gathered together into one place, and let the dry land appear.â
That is what it *means* when we say it. But it comes from exactly what it sounds like. In nature, the more still the top of the water in a river, the deeper that part of the river is likely to be. Thus, still waters are deep waters while fast waters are shallow. All you can see is the surface, but you can tell a lot by that surface. Someone just applied that natural observation to a human personality trait - just like saying the 'early bird gets the worm' to indicate a hard worker that gets rewarded for their efforts.
