Operations Management Flashcards
What is quality of design?
Meeting or exceeding the needs and wants of your customers.
What is quality of conformance?
Degree to which a product meets its specifications.
What is the best method to minimize failure costs?
Prevention costs.
What is the JIT inventory method?
Just in time. Company purchases inventory only when necessary and arrives JIT for its use of production or sales. There is a lower level of inventory maintained by the firm - therefore inventory turnover increases and inventory as a percentage of total assets will decrease.
What is an internal failure cost?
An internal failure cost is incurred when a product that does not conform to its design specification is detected before shipment to customers. An example would be rework.
What are statistical quality control programs?
They are preventative programs to detect/investigate/determine/solve issues with operations.
What is the only well-recognized quality program used to minimize defects while reducing costs?
Six Sigma
What are the performance measures for Financial Perspective of the Balanced Scorecard?
Economic profit, income from operating, working capital, operational cash flow, inventory turns.
What are the performance measures for Customer Perspective of the Balanced Scorecard?
Rank in customer surveys, market share, product returns as a % of sales, # of new customers, repeat order rate, complaints.
What are the performance measures for Internal Business Process Perspective of the Balanced Scorecard?
Reduction in process cycle time, # of engineering changes, capacity of utilization, order response time, process capability.
What are the performance measures for the Learning and Growth Perspective of the Balanced Scorecard?
Leadership competence, % of patent protected turnover, training days for employees.
What does benchmarking provide?
A relevant comparison when trying to achieve the optimal outcome by comparing to others.
What is comparing and contrasting financial info to published information reflecting optimal amounts an example of?
Benchmarking.
What is the formula fo economic value added? (EVA)
Net operating profit after tax
-(WACC)(Total Assets - Total Liabilities)
What is the WACC calculated as with the following information?
Firm has $40m in debt costing 10%, $60m in owners equity costing 14%, and a marginal tax rate of 40%.
WACC = (40m/100m)(10%)(1-.4) + 60/100(14%)
= .024 + .084
= 10.8%
The 100m is the total debt and equity
What is the equation for price elasticity of demand?
% Change in Quantity Demanded/% Change in Price
How do you calculate Residual Income?
Operating income - (Required Rate of Return x Invested Capital)
How do you calculate Return on Investments?
NI/Total Assets
What is the DuPont equation for ROI?
PM x Asset Turnover
Describe value based management.
Accrual based metrics are discredited, cost of capital is emphasized, shareholder and shareholder value are the primary elements of interest in common
What is the ROI with the following information?
Sales: $311,000 Variable Costs: $250,000 Traceable Fixed Costs: $50,000 Average Invested Capital: $40,000 Imputed Interest Rate: 10%
ROI = NI/Total Assets
Net Income = $311,000 - $250,000 - $50,000
= $11,000
ROI = $11,000/$40,000 ROI = 27.5%
Note: “Corporate” Fixed Costs would not be deducted.
Calculate residual income.
Asset (investment) turnover: 1.5 times (Sales/Investment)
Sales: $750,000
Return on Sales: 8%. (Profit/Sales)
Imputed Interest Rate: 10%
First solve for the asset turnover to get the total investments:
1.5 = $750,000/Investments, Investments = $500,000
Then, determine total profit (I.e. income) by using the return on sales.
8% = (Profit/$750,000) = $60,000
Then you can solve for the residual income:
$60,000 - (12% x $500,000) = $0
Gross Margin?
Revenue - COGS (used for traditional external reporting)
Contribution Margin?
Revenue - Variable Costs (used for planning purposes)
What is a Traditional Income Statement?

What is the inventory turnover?
Current Year Annual Sales: $2,525,000
Prior Year Annual Sales: $2,125,000
GP % Current Year: 40%
GP % Prior Year: 35%
Beg FG inventory for CY is 15% of PY annual sales
Ending FG inventory CY is 22% of CY annual sales.
Inventory Turnover = COGS/Avg Inventory
Beg Inventory = 15% x $2,125,000 = $318,750
End Inventory = 22% x $2,525,000 = $555,500
COGS = $2,525,000(1-.40) = $1,515,000
Inventory Turnover = $1,515,000/[(318,750+555,500)/2]
= $1,515,000/$437,125
= 3.47
Possible solution for COGS?
Annual sales x (1-GP%)
Solve for the amount of sales:
EBIT: $5,000,000
Jan 1 BV of Assets: $22m
Dece 31 BV of Assets = $18m
2.5 Investment turnover
Investment TO = Sales/Avg Investments
2.5 = Sales/[($22m + $18m)/2]
2.5 = Sales/$20,000,000
Sales = $50,000,000
What does the quick ratio measure?
Relationship between current assets that are cash or can be converted to cash quickly and then to current liabilities.
Why are inventories removed from CA in the quick ratio?
Current assets in the quick ratio include A/R and Marketable Securities because they can be converted quickly. Inventory cannot be converted quickly.
What is strategic risk?
L/T - and is best control through forecasting, planning and optimizing operating leverage
What is market risk?
Can be hazardous/natural disaster risk or economic risk. Can be controlled by insurance for specific hazards. However, economic risks cannot be controlled - they can assess exposure to economic downturns and use sensitivity analysis to evaluate their position.
What is operational risk?
S/T, daily implementation and best controlled by good execution of the firm’s strategic plan- particular attention to customer credit checks, quality, employee training, and management expertise.
What is systematic risk?
Also known as market risk or nondiversifiable risk - associated with large scale economic events or natural disaster typically affecting all companies to some degree.
What is the theory of constraints?
Determining where bottlenecks (constraints) exist and optimizing output by relaxing that constraint.
What can constraints result from?
Labor hours, machine hours, or square feet.
What is the optimization rule?
Maximize the CM/unit of the constrained resource
What is lean manufacturing?
Typically characterized by lower setup times, flexible equipment, and a high variety of unique products with highly skilled, cross-trainined labor.
What is mass production?
Typically characterized by higher set up times, dedicated equipment, and low skilled workers with a high degree of specialization.
What is the objective of demand flow/demand flow technology?
Is to link process flows and manage those flows based on customer demand.
What is Six Sigma similar to?
TQM (Total quality management)
What types of TQM tools does Six Sigma use?
Control charts, run charts, Pareto histograms, fish bone diagrams.
For short run profit maximization, a company should try to do what when it comes to manufacturing?
Manufature the product with the greater CM/hour of manufacturing capacity.
What does maximizing CM/hour also maximize?
Maximizes profits and cash flow as Fixed Costs remain the same.
What is the theory of constraints?
Determining where bottlenecks (constraints) exists and optimizing output by relaxing that constraint.
What can restraints result from?
Labor hours, machine hours of square footage limitations.
What is the optimization rule?
Maximize the CM/unit of the constrained resource.
What is Lean Manufacturing?
increasing quality, reducing waste, and minimizing resource consumption through eliminating steps in production that do not increase customer value and streamlining the prices.
What is lean manufacturing typically characterized by?
Small batches of high variety of unique products with highly skilled, cross trained labor, lower set up times and flexible equipment.
What is mass production typically characterized by?
Higher setup times, dedicated equipment, and low skilled workers with a high degree of specialization.

Link process flows and managed more flows based on customer demand.
What are the 5 processes of Six Sigma approach for continuous improvement to systematically reduce defects?
- Define
- Measure
- Analyze
- Improve
- Control
What is Six Sigma very similar to?
TQM - Total Quality Management - it uses TQM tools like control charts, run charts, Pareto histograms, and fish bone diagrams.
What should a company try to do in order to maximize short run profits?
Manufacture product with the greater CM/hour of manufacturing capacity.
Maximizing CM/hour also maximizes what?
Profits and cash flow since fixed costs remain the same.
What are prime costs?
Direct Materials and Direct Labor
What are conversion costs?

Is indirect labor also a conversion cost?
Yes.
What is manufacturing overhead?
Cost of labor and supplies that support production process but are not easily traceable to the finished product.
What are period costs/selling and administrative costs?
Cannot be matched with specific revenues (I.e. accountant’s salary) and are expensed in the period incurred.
What is the complete flow for goods to end up in COGS?
DM, DL, MOH -> WIP -> FG -> COGS
What are product costs assigned to?
Goods that were either purchase or manufactured for resale.
In a traditional job order cost system, the issue of indirect materials to a production department increases what?
Factory OH control.
In a process cost system, the application of factory OH usually would be recorded as an increase in?
WIP Inventory. When overhead is applied:
Debit WIP
Credit OH
What is beginning balance of direct materials at March 1st if the total purchases for the month were $350,000, used RM were $300,00 and Ending Direct Materials were $50,000?
Beg DM ?
+Purchases. $350,000
- Used RM. $(300,000)
End DM. $50,000
Beginning DM is 0 after solving for the missing piece.
How is normal spoilage accounted for?
Spread over the good units products.
How is abnormal spoilage accounted for?
Removing from the costing system and treated as a period cost.
How are the sales from normal scrap accounted for?
Used to reduce factory overhead costs, and thereby reduces COGS.
