Operations Strategy 1

Operations Strategy

� What is it?

� Generic Strategies

� Order winners verses qualifiers

� Generic Processes

� Order processing

� Service

� Design




Linkages for Strategy

� Key notion of strategy is that all functions must be pursuing functionalstrategies that support the business strategy.

± Classic misalignment - usually driven by measures and rewards

� marketing strategy based on differentiation and customization

� operations strategy low cost

� As a money person you need to understand how a company winsorders

± an investment in quality might not increase profits but it mightretain customers who would otherwise be lost (note marketing link as well) ± Nissan article

� As a money person you need to understand how work flows and thecosts of changes

� All managers should understand the tradeoffs inherent in some of the process choices they make (all managers manage processes)




Strategy - how do we accomplish our mission?

� If our mission is our company¶s purpose, what isour strategy ?

� For this class- strategy is Why a customer chooses

us as opposed to another provider

� Why do we need a strategy ?

� What are generic strategies / priorities?

± differentiation - better / unique

� quality / flexibility (customization) ± cost leadership- cheaper

� price / cost

± quick response- faster

� delivery speed / delivery reliability / new product introductions




Generic strategies: Differentiation- we do

something unique / better

� The customer defines better (keep this in mind

when we discuss quality)

� Examples:

± Rolls Royce - quality ± Sam Adams / Deschutes Brewing - quality

± Lightspeed - quality /flexibility / customization

± Dell ± flexibility / customization




Cost leadership - cheaper

� Lower cost (usually but not always price) than

main competitors

� Examples

± South West (price) ± General Motors (price)

± Wal-Mart (price)

± Maytag ± Neptune washers (cost)

� Less H2O and power � Fewer repairs (increased availability)




Quick response - faster

� We can provide a product (or service) faster and or

more reliably than the competition

� Examples

± McDonalds (Fast) ± Fed-Ex (Fast&Reliable)

± Panasonic (Fast)

± Caterpillar (Fast&Reliable)

± Sony (Fast)

± Chrysler (Fast)

� PT Cruiser verses GM¶s retro car ± due in 2006.




Order winners and qualifiers: a way to view

competitive priorities

� Order qualifier: those

attributes our product

must have to compete

± Airline

� safety� access (to destinations)

± Appliance

� functionality

� standard sizes and power

requirements

� Order winner: those

attributes that differentiate

our products:

± Airline:

� price (Southwest)� access (American)

± Appliance

� financing (Kenmore)

� cost (Magic Chef)

� durability (Maytag)




A process is?

� From an operations standpoint a process is a set of organized activities that are performed to add value for our

customer

± manufacturing processes

� fabricate / assemble / machine / form ± service processes

± there are many other processes directly related to OM

� order taking processes

� order filling processes

� inventory processes

� From a broader perspective everything we do has a

processes that can be understood, managed and improved

upon




More process

� The choice of process for any activity will effect: ± how fast it is

± how easy it is to change (flexibility)

± how expensive it is to buy and to operate

± the quality of the outputs

± the ability to customize outputs

� This is true for any business activity

± What are accounting processes ? Finance ? Marketing ?MIS ?




How work flows through our processes

influences our ability to be faster, better and

or cheaper.� There are two basic ways for work to flow through

processes for either a good or service

1) The Line Flow: all orders move through the same steps

in the same sequence (line and continuous on product

process matrix)

2) The Jumbled Flow: each order goes through different

steps in potentially different orders (job shop and batch

processing on product process matrix)

Key points of the product process matrix

� There are direct links between how we wish to sell(marketing) and how we produce our products / services

� As we become more efficient we tend to become less

flexible

� Line / continuous flows are faster (for standard products)than batch or job shops

� Job shops and batch production allows much more

customization

± Pirelli verses other tire companies

� Continuous production is very standardized and very low

cost (per unit basis - very expensive to install)




Other issues

� How does our process effect quality? ± Line flows are generally fast and inexpensive - does

that mean they are low quality ?

� Are line flows always faster than jumbled type

flows?

� What happens when we move off the diagonal

± high volume job shop

± low volume continuous production ?� Does this seem to apply for services ?

Order processing

� Make to order (MTO) verses make to stock

(MTS).

± MTO : we receive an order before we produce our good

or service.

� lead time = backlog + production + order processing time

± MTS : customer orders are satisfied out of inventory.

� lead time = order processing time




MTO - make to order

� Benefits

� Drawbacks

� Variations

± ETO: engineer to order ± ATO: assemble to order (BTO is usually a form of

ATO as well)




MTS - make to stock

� Benefits

� Drawbacks

� Services: We can not inventory a pure service.

How about impure services ?




Group exercise

� MTS / Line: Pizza by the slice

± American dream ± no special orders at lunch

� MTO / Line: Dominos ± only make a pie when

you order it- make it how you want it� MTS / Jumbled: Pizza Hut Lunch Buffet ± all

sorts of vaguely Italian food sitting and waiting for

you- can¶t make pasta in a pizza oven

� MTO / Jumbled: Pasta Petes (Italian restaurantand pizza place in Eugene)




Group exercise questions

� What are the order qualifiers for your industry?

± Do these have any influence on process choice?

� What are the order winners for each individual

company? ± Would you expect similar order winners for companies

in other industries with similar processes?




Interaction of work flows and order

processing

� Note how our strategy / order winners are related

to the choices we make.

± If customers demand lots of variety and you compete

on costs what will you do?� ATO on a line is one possibility

� MTS jumbled flow is another possibility

� What is the difference between the two choices?

± In the same market if you competed on higher levels of

customization what would you do?� MTO and jumbled?

� The key point here is that our processes should

match our strategy !




Customer service and OM

� Definition: giving the customer what they want, when they

want it, every time they want it .

� How can OM effect CS ?

± process choice

± process location

± inventory

± scheduling

± capacity planning

� Does service link to the strategy?

� Does service = satisfaction ?




Does service = satisfaction ?

Satisfaction




Elements of satisfaction

� Cost and quality: two chief concerns of OM that

we will discuss in detail.

� Service: OM strategy decisions impact service.

± Why does service stink article and banks� Design: Not a traditional OM responsibility.

However, at many companies OM has a part in the

design of products and process.




Why is OM involved in design ?

� In order to produce a design we must have the

operational capability. Many companies wish to

answer the question ³can we make it´ early in the

design process. ± Time to design a product

± Cost of design and design changes

� Design processes

± Traditional ± Harlan Co

± Concurrent: DFM and DFE

� DFX- design for X (something)




Harlan co

� Small KC company that makes equipment to

move planes around airports (tractors?)

± Very traditional design process

± Engineers will specify an entirely new part when anexisting one will do

� Lots of excess parts- lower volumes increase prices and

reduces quality.

± Production does not see the design until it is ³ready´ for

assembly ± and then they often have to toss it back over the wall

± Purchasing is in same position as production




Advantages of concurrent design and DFX

� Speed: no more tossing things over the wall.

� Cost- problems surface earlier in the design process (also effects speed).

� Quality - do not try and make things we are notcapable of.

� Example ± Xerox DFE (environment)

± All copiers are designed to be remanufactured

� Have to be easy to disassemble and rebuild

± Use more screws and other hard fasteners as opposed toclips

� generally use standard sized parts even when new modelsintroduced




Generalizing from design processes

� DFX / concurrent design are ways to link multiple

functions ± can you expand upon this to other types of processes that also involve other functions?

± Another way of asking this question: If you are

in charge of process that influences a number of other people (functions, members of the supplychain) does the idea of concurrency have value?

� i.e. Development of marketing plans

� Key point- you may never be involved in design processes- but you are likely to be working with a process that involves multiple entities and the notionof concurrency may matter a great deal.




Specific choices and strategy

� Work flow: line flows are generally cheaper. They

are also faster for standard products, but slower (if

this is even possible) for custom products.� Order processing: MTS has higher inventory costs

but is faster. What type of products are MTS ?

MTO ? What can we do to try and decrease lead-

time in MTO ?




More strategy choices

� Design: By involving manufacturing in design we

may be able to reduce costs and lead-time. WHY ?

� Key point: Our company¶s definition of customer

service and satisfaction leads to specificoperations strategy choices. As it leads to specific

marketing / accounting/ etc. / choices.




Strategy: conclusions

� OM goals are to be faster, better and / or cheaper.

� What is the purpose of operations strategy.

± To determine the right mix of faster, better, and cheaper to satisfy our customers (to prioritize or if you will to

make trade-offs).

� process choice, work flow, order processing,

inventory, capacity, etc..
