Suppose you are the senior controller for Spine Line and you plan to perform a variance analysis of the massage chairs manufactured to determine if the standards are being met. Once you have completed the analysis, you plan to show it to the production department manager and ask for an explanation of any variances that you believe should be examined. 

The Assignment:

?Part 1: Calculate all materials and labor variances in a spreadsheet by using a program like Excel. Be sure to include price, quantity, wage rate, and labor efficiency variances.
?Summarize and analyze the actual costs in relation to the standard costs incurred for the month.
?Ask for clarification of any variances that need to be investigated.
