Typical problems with resource assignment and manpower in project management include:

1. **Overallocation**: Team members may be assigned too many tasks at once, leading to burnout and decreased productivity.
2. **Underutilization**: Some resources may not be fully utilized, resulting in inefficiencies and wasted potential.
3. **Skill Mismatch**: Team members might not have the necessary skills for the tasks they are assigned, leading to poor quality work or delays.
