I agree that a major pitfall is scheduling conflict as many team members will not always be available and team members taking vacations and time off can severely impact the time line of the project. In addition, I do believe that another major pitfall would be a lack of necessary resources to complete the project. This can result from a budgeting problem where a subgroup is unable to get their necessary supplies to complete their part of the project. Therefore, this will hold up the other team subgroups as they can not follow through on their part of the project if the schedule is set to happen in chronological order. Also, a major pitfall too with resources is if something breaks or becomes damaged in the process of manufacturing or shipping and now the team has to redo their work, which may force other teams to do more work and stop other teams from completing their work. In addition, the planning phase goes over creating an estimated activity duration for each subset of the project. This is just an estimate though and some tasks may take a lot longer to complete which can mess up the time table and push the project back further and further. In addition, another pitfall could be not identifying all potential risk, and then running into unexpected complications later on that can halt the project. If a project team can effectively create a successful scope and make sure they are as accurate as possible with estimated costs and time then a project team can avoid pitfalls and major complications.
