What is a common cause of cost overrun?

• A. Not allocating an adequate amount of budget.
• B. Over-estimated Project Complexity
• C. Fall-back Plan takes place
• D. Feasible Cost Estimates

Answer: (A)

The main idea here is that cost overruns often happen when the budget assigned at the start isn’t enough to cover what the project actually needs. If the initial funding is too low, any changes in scope, unforeseen conditions, price increases, or delays drain the available money quickly. Without a proper contingency or reserve, project teams are forced to seek extra funding, cut scope, or push work into later phases, all of which can end up raising total costs beyond the original estimate. Think of it this way: a solid budget should include a contingency based on identified risks and a realistic estimate of unknowns. When that cushion is missing, even normal project pressures can push costs past the budget. The other scenarios don’t typically cause overruns. Over-estimating project complexity tends to raise the budget up front rather than cause overruns, and in some cases can prevent overruns by providing extra protection. Having a fall-back plan is a proactive risk-management move, not a direct cost-driver. Feasible cost estimates reflect careful budgeting and reduce the likelihood of overruns, not cause them.
