Thomas Looy: How Long is a Piece of String?: “- Use working software as the only measure of the progress on a project (no more 90% completed tasks);
- Measure using smaller sized tasks. Smaller tasks give you better measures than larger ones and will also give you a larger sampling of measures that can be used for meaningful statistical evaluations. Smaller tasks are also completed sooner and therefore give you measurements sooner that you can begin to use to extrapolate to a meaningful project complete date.”
