It is crucial to maintain a strong relationship with your finance team. They are key partners who ensure that your projects and team have the resources needed to succeed. A successful budget exercise is when, at year-end, you complete your year on target by delivering what we promise in time and quality.
Therefore, What are the keys to Budgeting for Success?
Mastering the budgeting process takes time and experience. The ultimate goal is to meet your budgetary targets by year-end. Both underspending and overspending can have negative consequences for your team and the company.
Overspending – Several factors can lead to overspending:
- Optimistic Project Cost Estimates: Underestimating the potential costs of a project can quickly lead to overspending.
- Lack of Budget Tracking: Failing to track your budget throughout the year means you lose control of your spending rate. This erodes trust with the finance team and can make future budget negotiations more difficult.
- Inaccurate Forecasting: If your initial predictions are inaccurate, it’s essential to learn from your mistakes. To improve future forecasting, always compare your initial estimates to the final costs, including employee hours.
Strategic Overspending – The only time I authorize overspending is when:
- Year-End and Available Funds: Finance identifies unspent funds near the year’s end, and accelerating certain expenses can benefit your projects.
- Acceleration and Risk Reduction: Spending the extra funds must accelerate the project timeline or reduce execution risks.
- Early Hiring (Rare): In limited cases, hiring ahead of schedule can be beneficial to smooth the onboarding process for new team members.
Underspending – Common causes of underspending include:
- Contingency Mismanagement: Overestimating contingency funds for projects, especially in a portfolio of small to medium-sized projects, can lead to significant underspending. To prevent this pitfall, my approach is to deploy strict contingency management. A pragmatic approach to contingency funds is essential. In a portfolio of 20 projects, for example:
- 25% may require a 20% contingency.
- 25% may require a 10% contingency.
- The rest should stay on target.
Track budget expenditures precisely and adjust contingency funds as uncertainties decrease. This will allow you and your team to control your budget more precisely and deliver on your promises.
Other Factors
- Recruitment Challenges: During periods of growth, underestimating the time and complexity of hiring new team members can also cause budget variances. Partnering with HR can help streamline this process.
Forecasting and re-forecasting: An opportunity for the manager.
Due to unpredictable project needs and market conditions, regular forecasting and re-forecasting are essential. Accurate forecasts enable finance to allocate resources effectively, preventing budget overruns or shortages. If you anticipate underspending, release funds promptly so they can be used elsewhere.
Cost vs. Value
A typical budget trap is examining the allocated amount for the project as a standalone, especially if some budget remains unallocated as the project progresses and some provisions will no longer be needed. Train your team to continually evaluate whether additional spending truly adds value to the project. Don’t spend simply because you have the budget for this project. The unspent amount could generate more value in another project.
Building Trust with Finance
Effective budget management and delivering on your promises build trust with the finance team. This trust translates to a more significant influence in securing future budgets and ensures your team has the resources to deliver high-quality work on time.
