I think that not doing enough research could lead to more pitfalls. The more research you do the more you can expect and prepare for when things come up. Research also includes looking into calendars and schedules of the people on your team. They all need to know the dates they are needed and compare that to their schedules to account for vacations, doctors appointments, and other days they plan to not come to work. They might bring things up that you forgot about. Expecting the unexpected should be applied to a gantt chart by adding in slack time so that deadlines aren’t missed. You want to add enough time so that you have a cushion but not too much to where there is time wasted for excessive task times. Pitfalls also occur when resources you need are not readily available when you need them. Planning involves plotting out what needs to be done but making sure everything you need to complete them is accounted for.
