If Amol, a Green Belt of a Six Sigma project, misses to re-validate the Cost Benefit Analysis in the Improve phase and the cost benefit equation changes, which of the following challenges can he face? This question is required.* A Amol may miss to document any potential change in the cost assumptions that were taken at the beginning of the project B Amol may announce that his project has saved USD 90,000, but later finds out that his project has only saved $36,000 as the earlier cost assumptions became obsolete by the end of the project C Amol may have to make last minute adjustments in Cost-Benefit calculations when he is about to present his project to the Champion D Amol may get reprimanded by the Project Champion as the Cost Benefit Analysis (which is considered to be a vital component of any Six Sigma project) had incorrect assumptions E All of the above
