Which tool or technique is used in the Estimate Costs process?

In accordance with the PMBOK® Guide (Project Cost Management), the Estimate Costs process involves developing an approximation of the monetary resources needed to complete project work. Vendor bid analysis is a recognized tool and technique used to assist in this estimation.

Function of Vendor Bid Analysis: When project deliverables are to be purchased from outside the organization, the project team can use the bids submitted by qualified vendors to help estimate what the project costs should be. This involves analyzing the various bids to determine the " should-cost " of the work based on the responses from the marketplace.

Cost Estimating Context: It provides a reality check against internal bottom-up or analogous estimates. If a vendor ' s bid is significantly different from the internal estimate, it may indicate that the project scope was misunderstood or that the internal estimate was flawed.

Other Tools and Techniques: Other primary tools in this process include Analogous Estimating, Parametric Estimating, Bottom-up Estimating, Three-Point Estimating, and Data Analysis (specifically Alternative Analysis and Reserve Analysis).

Analysis of Distractors:

A. Acquisition: This is a tool and technique used in the Acquire Resources process (Project Resource Management). it refers to the actual act of obtaining team members, facilities, equipment, or materials, rather than estimating their cost.

B. Earned value management (EVM): This is a methodology used in the Control Costs process. While it uses cost estimates as a baseline, EVM is a monitoring and controlling technique used to measure project performance and progress.

D. Forecasting: This is an output or a technique used in Control Costs to predict future cost performance (e.g., Estimate at Completion - EAC) based on current work performance data. It is not used to create the initial estimates for the project activities.
