DEVELOPING UNIT INPUT STANDARDS
• Price Standards specify how much should be paid for the quantity of the input to be used• Quantity standards specify how much of
the input should be used per unit of output• Unit standard cost is the product of these
two standardsStandard price × Standard Quantity (SP ×
SP)

DEVELOPING UNIT INPUT STANDARDS
Establishing Standards•Ideal Standards demand maximum efficiency and can be achieved only if everything operates perfectly•Currently attainable standards can be achieved under efficient operating conditions

DEVELOPING UNIT INPUT STANDARDS
Kaizen Standards•Standards and Activity-Based Costing• An activity’s cost is determined by the amount of
resources consumed by each activity• Standard consumption patterns are identified based
on historical experience• Activity-based systems also use standards for
control, where control is specifically defined as cost reduction
• Activities are classified as either value-added or non-value-added

STANDARD COST SHEETS
• Standard costs are developed for direct materials, direct labor, and overhead used in producing a product or service• Total of these standard costs yields the
standard cost per unit
• Standard cost sheet provides the detail underlying the standard unit cost

VARIANCE ANALYSIS AND ACCOUNTING: DIRECT MATERIALS AND DIRECT LABOR
• Flexible budget : used to identify the direct material or direct labor input costs that should have been incurred for the actual level of activity• Total budget variance: the difference
between the actual cost of the input and its standard cost
Total budget variance = (AP × AQ) – (SP × SQ)

Investigating Direct Materials and Labor Variances•As random variations around the standard are expected, management should establish an acceptable range of performance•The acceptable range is the standard, plus or minus one allowable deviation•The top and bottom measures of the allowable range are called the control limits• The upper control limit is the standard plus the
allowable deviation and the lower control limit is the standard minus the allowable deviation

MIX AND YIELD VARIANCES: MATERIALS AND LABOR
• Mix variance: created whenever the actual mix of inputs differs from the standard mix
• Yield variance: occurs whenever the actual yield (output) differs from the standard yield

MIX AND YIELD VARIANCES: MATERIALS AND LABOR
Direct Materials Mix Variance•Difference in the standard cost of the actual mix of inputs use and the standard cost of the mix of inputs that should have been used•If relatively more of a more expensive input is used, the mix variance will be unfavorable•If relatively more of a less expensive input is used, the mix variance will be favorable.

MIX AND YIELD VARIANCES: MATERIALS AND LABOR
Direct Materials Yield Variance•Designed to show the extent to which the amount of input resulted in the expected amount of outputYield variance = (Standard yield – Actual yield) SpywhereStandard yield = yield ratio × total actual inputsYield ratio = total output/total inputSPy = Standard cost of the yield
