Estimating project costs can be a difficult task, especially for complex projects in IT or engineering, but several effective cost-estimating techniques exist that can help streamline the process. By employing the three methods described below, you’ll be better equipped to create a realistic, manageable, and more accurate cost estimation for your IT project, helping to ensure its success.
1. Examine similar projects: One of the most reliable ways to estimate costs is to look at earlier project budgets that share some similarities with your new project. By analyzing previous projects’ expenditures, you can identify patterns and benchmarks that will inform the cost estimation of your current project.
Sure, market rates change all the time, so the resources required to hire all team members in 2014 are basically irrelevant. However, by examining historical data, you can notice things like hidden costs linked to infrastructure needs or licensing, unforeseen additional costs resulting from shifts in client requirements, or the impact of modifying a project schedule or a project’s scope on the real-life project budget.
Understanding the direct and indirect costs that had an impact on similar past projects allows you to better gauge how factors like scope, technology, and resource allocation impacted the previous project’s actual cost and use it to make a more accurate estimate this time.
2. Conduct simulations: Running simulations of several various project scenarios results in obtaining useful insights into possible project costs. By creating multiple hypothetical examples with varying parameters (including team size, technology stack, and timeline), you can better understand how such changes affect the overall budget.
This method allows you to formulate a more flexible project budget plan and prepare for a range of possible challenges, consequently increasing the odds of project success.
3. Use a budgeting tool: Leveraging digital budgeting tools (for example, spreadsheet templates or project management software) can significantly enhance the precision of your project cost estimation process.
Such tools usually allow you to input various cost factors in each project phase and automatically generate comprehensive budget forecasts so you can easily identify areas where costs might escalate. Maxima Consulting budget templates also allow you to track project costs and compare actual costs with cost estimates in real-time.
