Which scenario is an example of proactive budget management?
1) You're reviewing your budget and realize that it took much longer than you anticipated for a subject matter expert to complete a task. The labor cost associated with this task is now well over budget. You must now request a budget increase to cover the cost of the labor.
2) While planning your project budget, you decide that you don't need to add buffers for unexpected costs. Since you've completed several projects like this one in the past and have always come in under budget, you feel you don't need to plan for any extra cost.
3) While planning your project budget, you gather historical data and consult with industry experts. You consider fixed costs, add relevant line items, and set aside a 5% contingency fund to cover unexpected expenses.
4) During your project, the market experiences a shortage of a resource that's crucial for your project's success. Because of the shortage, the price of this resource increases. This is something you did not expect, nor plan for, and must now figure out how you can afford to complete your project.
