Unknown Facts About The 8/80 Rule For Projects


The 8/80 Rule for projects refers to a general guideline regarding work packages; they require more than eight and fewer than eighty hours of effort to be completed.

The 8/80 Rule help project managers create the work package list by identifying which work components should be considered work packages.

Any work component that can be completed in fewer than eight hours does not rise to the level of a work package.

Also, any work component requiring more than 80hours of work is too monumental to be categorised that way.

While the 8/80 Rule may be a useful guide in small projects, it will be impractical to apply it to large projects, which will necessitate tracking millions of work packages.
