Preparing PMI-SP certification

As a complement of the PMP (Project Management Professional) certification, PMI has created two more, namely, Scheduling Professional (SP) and Risk Management Professional, focussed on the respective knowledge areas.

While preparing the PMI-SP exam and taking a training course (delivered by IIL) for that purpose, I realized an important issue I would like to share.

Scheduling seems to be mostly related to Time and Cost Management areas and one can reasonably think they are the only chapters of the PMBok to study for the exam, beside "The Practice Standard for Scheduling" and I would like to point out that, although those chapters are key for the exam, there are some others related to Scheduling which must be reviewed as well: Integration, Scope, Human Resources, Communications and Risk Management.
Those knowledge areas are related to the project scheduling function as the required to be taken into account to create, analyse, maintain and report the project schedule.
