Common shortfalls of budget control in project management include:

1. **Inadequate Planning**: Failing to create detailed and realistic budgets during the planning phase can lead to financial issues later in the project.

2. **Poor Tracking of Expenses**: Not regularly monitoring expenditures against the budget can result in overspending or unexpected costs.

3. **Lack of Stakeholder Communication**: Inadequate communication with stakeholders about budget changes can lead to confusion, conflicts, and misalignment of expectations.

4. **Ignoring Contingencies**: Not setting aside appropriate contingency funds can leave a project vulnerable to unexpected expenses.

5. **Inflexible Financial Processes**: Overly rigid budgeting processes that do not allow for adjustments based on changing project circumstances can lead to financial constraints.

6. **Insufficient Training**: Lack of training for project managers and team members on budget management can lead to errors and mismanagement.

7. **Failure to Reassess**: Not regularly reassessing the budget during the project lifecycle can cause issues to go unnoticed until they become significant problems.

8. **Underestimating Scope Changes**: Failing to account for potential scope changes and their financial implications can lead to budget overruns.

By being aware of these pitfalls, project managers can take proactive steps to enhance budget control throughout the project lifecycle.
