Project Management Cost Estimating: Tools and Techniques Made Simple
When people manage projects, like organizing a wedding, running a cricket tournament, or planning a school function, they need to determine the costs involved. Project managers use various tools and techniques to estimate these costs. Here are the main ones, along with simple examples: 1. Analogous Estimating (Top-Down Estimating) This method uses the cost of a previous, similar project to estimate the new one. Example: Last year, your colony celebrated Ganesh Chaturthi with a small pandal and decorations costing ₹20,000. This year, you plan something similar, so you might estimate the cost to be about ₹20,000 again. Key Point: It’s quick, but may not always be accurate. 2. Parametric Estimating This involves using a rate or formula to calculate costs. Example: You know that catering for a wedding costs around ₹500 per person. If you expect 200 guests, then: ₹500 × 200 = ₹1,00,000. Key Point: This method works best when the rate is dependable. 3. Bottom-Up Estimating In this approach,...
