Which of the following is not true about value?

Value is determined subjectively by design engineers.

The cost approach to pricing:

means prices are set to cover direct costs, contribute to indirect costs, and provide a profit.

quality

notions of function, suitability, reliability, and conformance to specifications function- action designed to perform suitability- ability for item to meet intended function reliability- will function over certain amount of time

Risk management 3 categories

operational: interruption in flow of goods/services financial: price or total cost of goods/services will change reputational: reputation adversely affected by method of acquisition or behavior of supplier

true

Logistics is responsible for the management of inventory in motion and at rest.

true

MRP

•Designed for "push" or forecast-driven systems ••Master production schedule: »How many and when do we need them •Inventory record: »What do we have and what do we need (consider lot size policy, lead times) •Bill of material (BOM): »What do we need to make one end product

problems with inspection

•Does not change nor adds value to the product •Does not correct revealed problems »product deficiencies »system deficiencies »Practically is just a Post Factum detection tool •Does add cost •Duplication of inspection activity can take place •Often a large number of items need to be inspected

Which statement is most accurate when deciding how much and when to buy?

Managers seldom make purchase decisions until they are absolutely sure of the volume required. Use the forecast future demand and lead times to determine optimal order volume. The costs of placing orders and holding inventory are so low they do not significantly affect the decision of how much to buy. Determine the price premium to attain the desired order quantity. **Balance price, volume, carrying cost, and the cost of stock-outs.**

The correct statement describing a general condition of economic competition is:

Mopoly is the condition when there is only one provider in the market, and he will be able to charge the price that will best fit his interest

-Can any part be eliminated without impairing the operation of the complete unit? -Can the design of the part be simplified to reduce its basic cost? -Can less expensive but equally satisfactory materials be used in the part? -Can the design of the part be changed to permit the use of simplified or less costly production methods?

sample of value engineering checklist

1.Can the item/component be eliminated? 2.If the item is not standard, can a standard item be used? 3.If it is a standard item, does it completely fit the application, or is it a misfit? 4.Does the item have greater capacity than required? 5.Can the weight be reduced? 6.Can we substitute the item with a similar one that we already have in our inventory? Are the specified tolerances closer than necessary?

specification problems

1.Lack of clarity SPotential multiple problems on the road 2.Limiting the competition SImproper description that results in a reduced number of potential suppliers SHigher chances to develop supplier dependency 3.Unreasonable tolerances Potential cost increase without adding value

The factors stemming from competition determine the exact price each firm will quote. That is, when faced with the realities of competition, the price any specific firm will quote will be governed largely by its need for business and by what it thinks its competitors will quote.

true

The selection of the FOB point is important to the purchaser, because it determines:

who pays the carrier, when legal title to goods being shipped passes to the buyer, who is responsible for preparing and pursuing loss or damage claims and who routes the freight.

political factors

willingness to support government priorities

Compeition

»Pure Competition (1) -Many competitors -Buyers show no preference between products or providers -Supply and demand determines prices »Imperfect Competition -Monopolistic Competition (product differentiation, many providers) (2) -Oligopoly (few competitors, products could be (automotive) or not be differentiated (Al, steel)) (3) »Monopoly (4) -One seller controls entire supply

When determining lot size

»the costs of carrying extra inventory versus »the costs of purchasing more frequently • •The overall Objective: »To minimize the Total Annual Costs

types of carriers

•Common carriers -Offer transportation service to all shippers (including general public) at published rates, in a nondiscriminatory basis, between designated points. •Contract carriers -For-hire carrier that provides service to a limited number of shippers and operate under specific contractual arrangements that specify rates and services (not serving general public). •Exempt carriers -For-hire carriers, but exempt from regulation of rates and services. Mainly for transporting seasonal agricultural commodities. •Private carriers -Provides transportation for its company's own products and the company owns (or leases) all related equipment and facilities.

JIT

•Few, nearby suppliers •Frequent deliveries in small lots •Steady supply rate •Buying firm schedules inbound freight •Buying firm helps suppliers meet quality •Long-term contract agreements

•Lot-for-lot (L4L) »Based on net requirement per time period •Economic order quantity (EOQ) »Based on annual demand and considers order and inventory costs •Least-total-cost (LTC) »A dynamic tool resulted in the least expensive lot •Least-unit-cost (LUC) »Dynamic tool that balances setup and inventory holding cost to determine the optimal cost per unit

inventory costs

•Ordering/ purchasing costs: »managerial, clerical, material, telephone, mailing, fax, e-mail, accounting, transportation, inspection, and receiving costs associated with a purchase order •Setup costs: all the purchaser and supplier's costs of setting up a production run

8 dimensions of quality

•Performance: Deliver the primary function of the product or service. •Conformance: The meeting of specifications. •Reliability: The probability of failure within a specified time period. •Durability: The life expectancy. •Serviceability: The maintainability and ease to fix. •Features: The bells and whistles. •Aesthetics: The look, smell, feel, and sound. •Perceived quality: Customer's perception.

Costs of Quality Categories

•Prevention costs »Costs encounter when preventing poor quality in products or services »Examples: preventive maintenance, process capability evaluations, quality improvement team meetings, quality education, training •Appraisal costs »Costs associated with assuring conformance; evaluation, measuring, auditing »Examples: inspections, tests, service audits •Failure costs »Result from products or services not conforming to requirements of customer »Two categories: internal and external »Internal examples: scrap, rework, redoing inspection, and downgrading »External examples: processing customer complaints, customer returns, warranty claims, and product recalls

leased equipment

①Operating Lease SFocus is on operating convenience and flexibility SFirm is usually not interested in ownership SMost operating leases are short term SMost often used when firm wants freedom/flexibility ②Financial Lease SPrimary motivation is financial (buyer needs financing) SUsually they are long‑term SLease length should be shorter than the life of the equipment SMany financial leases are non-cancelable
