Rajdeep, good point. We have seen increasingly complex project specifications and schedule compression, so i feel we should be able to identify and monitor schedule variance to deliver projects on a timeline that satisfies owners' demands. Understanding which factors cause schedule variance, such as change orders and weather, allows you to properly plan, communicate, and coordinate resources, to ensure higher quality output, improved safety, and better resource utilization and allocation.....

ROCE = Return on Capital Employed = Net Earnings / Avg. Net Fund Employed... (Reduced for a year...!!!)
