Cost Estimation - Resource Method

Business Case

Problem Statement

Traditional costing challenges:

Fixed unit prices become outdated
No visibility into cost components
Difficult to adjust for conditions
Limited cost analysis capability

Solution

Resource-based costing separates physical resource consumption (norms) from prices, enabling accurate, adjustable, and transparent cost estimation.

Technical Implementation
