Frequently asked questions about project decomposition
Project decomposition methods can be successfully used not only by managers organizing work to achieve large-scale goals. They are useful in everyday life, as they help to correctly distribute time and effort, foresee important moments and predict possible obstacles.
How many points should each task be broken down into?
The optimal option is 5-6 points. You can use this number as a guideline, but proceed from the specifics of the project, available resources, and the professionalism of the performers. The main thing is that the plan includes all the steps necessary to achieve the project goal.
What else should be taken into account when decomposing?
Provide time reserves in case of force majeure. No one is immune from unforeseen situations. If everything goes smoothly, the project can be completed ahead of schedule or the saved time can be spent on carefully working through the most labor-intensive tasks.

Since all actions for the implementation of the project are predicted, any deviation can disrupt the established structure. This forces us to abandon alternative options, even if they are clearly better than those described in the plan.
