Operations Management Flashcards
What’s control chart & how is it used as a statistical quality-control total?
- Statistical plot that helps to detect deviations before they generate defects
- Used in statistical quality control and determine “zero” defects
What’s pareto diagrams used for?
How frequently a type of defect may occur
What’s fishbone diagram used for?
- Used to analyze the source of potential problems and their location by cause and effect
What is the formula for cost of goods manufactured (COGM)?
Beginning WIP
+ DM, DL, OH
- Ending WIP
= COGM
What is the formula for cost of goods sold (COGS)?
Beginning finished goods
+ COGM
- Ending finished goods
= COGS
Beginning inventory
+ Purchases
- Ending inventory
= COGS
What is difference between job order costing & process costing?
- Job Order Costing: Expensive, heterogenous, tailor-made, unique
- Ex: Aircraft, Printing, Industrial research projects
- Process Costing: Continuous mass-produced, costs are determined by activity/process/department
- Ex: Gas, Oil Steel, Ruber, Lamber
How are equivalent units calculated using FIFO?
Beginning WIP x % to be completed
+ Units completed - Beginning WIP
+ Ending WIP x % completed
= Equivalent units
How are total costs calculated using FIFO?
Current cost only/Equivalent units
How are equivalent units calculated using weighted average?
Units completed
+ Ending WIP x % completed
= Equivalent units
How are total costs calculated using weighted average?
Beginning cost + Current cost/ Equivalent units
Formula for absorption method
Sales
Less: Variable & Fixed COGS
Gross Margin
Less: Variable & Fixed SG&A
Operating Income
Formula for variable (contribution) method:
Sales
Less: Variable COGS, SG&A
Contrbution Margin
Less: Fixed OH, SG&A
Operating Income
Explain the difference between contribution & abosrption approach:
Treatment of Fixed OH
- Abosorption: Product cost
- Contribution: Period cost
Formula for contribution margin ratio
Contribution Margin / Revenue
* CM = Selling Price - Variable Costs
Formula for breakeven point in units
Fixed Cost + Pre-tax Profit
SP - VC [CM]
Formula for breakeven point in $
Fixed Cost + Pre-tax Profit
CM Ratio
* CM Ratio = Unit Price x Breakeven in Units
Formula for margin of safety in dollars:
Total Sales - Breakeven Sales in Dollars
Formula for setting selling prices based on assumed volume:
Fixed costs + Variable costs + Pretax profit
of units sold
Formula for fixed spending OH:
Spending Variance = Actual FOH – Budgeted FOH
Identify direct materials variances:
- Price = AQ x (SP - AP)
- Quantity (Usage) = SP x (SQ - AQ)
Actual < Standard (Favorable)
Actual > Standard (Unfavorable)
Identify direct labor variances:
- Rate = AH x (SR - AR)
- Efficiency = SR x (SH - AH)
Actual < Standard (Favorable)
Actual > Standard (Unfavorable)
Formula for sales price variance:
(Actual SP per unit - Budgeted SP per unit) x Actual units sold
Formula for sales volume variance:
(Actual sold units - Budgeted sold units) x Standard CM per unit
What’s cause-and-effect diagram?
- Identify potential causes of failures/defects
- Used to identify the reasons why a process goes out of control
Formula for free cash flow
Operating Income ‘After’ Taxes (NOPAT)
+ Depreciation & Amortization
< Capital Expenditures >
< Change in Net Working Capital >
= Free Cash Flow
What are the product costs?
- Direct material
- Direct Labor
- Overhead
Formula for book value per share
- C/S + Retained Earnings / Outstanding Shares
What’s cross-sectional analysis?
Comparing results and ratios with other firms in the same industry
