Project Schedule Management - How to
Errors in scheduling are one of the biggest problems in the project life cycle. Everybody knows that instinctively, but ignores the problem and claims that he/she does not make that mistake himself/herself. Among other things, the following sources of error seem to contribute significantly to the problem:
- Unclear project scope and requirements definitions,
- Insufficient decomposition of deliverables into manageable work packages, activities and tasks,
- Disorganized schedule preparation and without focus on how the schedule should be used in the future,
- Duration estimates without sufficient input from subject experts,
- No or insufficient risk evaluations,
- Inflexible organizations and/or project team leaders,
- Creation of the schedule under too much time pressure and regarded as a necessary evil, instead of giving it the necessary meaning.
