4、 varies,So what determines relative firm performance?In Competitive Advantage he tried to answer this?Porter,cont.Competitive advantage argues that it depends on the firms ability to manage the cost drivers/differentiation drivers so as to produce a cost advantage or a differentiation advantage.But
5、this approach has problems and is incomplete.Some questions about Porter Why does the successful firm not buy the unsuccessful and teach it how to minimise costs?Why does the successful firm not sell its expertise in cost reducing to less successful firms?Why does the successful firm not cut its pri
6、ces and drive its competitors out of business?Why does the unsuccessful firm not bid for the executive(s)in charge of cost drivers from the successful firm?These do happen:e.g.battle between General Motors and Volkswagen for the services of cost guru Mr.Lopez.Porters recipe If it is possible for Mic

9、pproach Question:What could give a particular firm a sustainable edge over its rivals?A series of influential articles in the HBR during the 90s suggested a new approach(although it turned out its origins were much earlier)Prahalad and Hamel(1990):core competencies Managements ability to consolidate
10、 technology and production skills into competencies so the business can adapt quickly to changing opportunities/circumstances.Core competencies=collective learning of the organisation about prod/tech/markets.e.g.Sonys miniaturisation skills.Competencies have to be built over a long period.They are d
11、ifficult to identify precisely and hard to imitate.Many firms fail to identify their own core competencies and so fail to nurture them properly or exploit them fully.Stalk,Evans,and Shulman(1992):capabilities Competitive advantage is based on the ability to respond to evolving opportunities which de
12、pends on business processes or capabilities.Business success involves choosing the right capabilities to build,managing them carefully,and exploiting them fully.e.g.Honda,Canon.Chandler(1990):initial risky investments Chandler(1990):successful giants such as IBM and Bayer derive from the initial hea
13、vy and risky investments in building organisational knowledge and capabilities which allowed them to exploit the opportunities available to exploit scale and scope economies.Collis and Montgomery(1995):competing on resources Competitive advantage derives ultimately from the ownership of a valuable r
14、esource.Superior performance derives from developing a competitively distinct set of resources and deploying them in a well conceived strategy.Resources can be physical,intangible,or organisational capabilities.Example:Marks and Spencer(poor timing!)John Kay(1993):Distinctive capabilities.In his bes

16、S)Distinctive capabilitiesKay identifies only three basic types of distinctive capability:Corporate Architecture Innovation Reputation.Distinctive capabilities What is it about these things in particular?Difficult to build and maintain.Difficult to codify/make into recipes.Difficult to copy/emulate.
17、Cant simply be bought off the shelf.Strategic assets He also discusses market dominance(monopoly)based on the ownership of strategic assets as a source of success.Natural monopolies such as utility networks,or licensed monopolies such as the national lottery.And those based on heavy sunk costs which
18、 discourage challengers for the first mover.But he argues that in these case it is essentially structural factors that count not distinctive capabilities.There may of course be room for debate in some cases.Architecture as a distinctive capability Concerns organisational effectiveness in the search
19、for value.Connects back to the discussion of corporate objectives and the co-operation needed to get things done in P&S chap 4.How to focus individuals on achieving organisational goals.ArchitectureThe network of contractual relationships which defines the firm.The capacity of organisations to:1.Cre

21、ossible.But NB it also influences what you choose to do(strategy)in the first place.Because?Architecture is about organisational form,incentive mechanisms,work organisation,performance evaluation,and governance.Architecturee.g.IBM in its heyday,Marks and Spencer(back when!),Liverpool Football Club.e

23、nArchitecture Now a specialised study area.See for example,Brickley,Smith,and Zimmerman:Economics and Organisational Architecture.Reputation as a distinctive capability This is about conveying information to consumers about quality.But it isnt equally important for all goods and services.It applies
24、to a particular category of goods called,Long term experience goods.These are goods where product quality is vital to the consumer but where it is difficult for the consumer to establish quality except through time and experience.Reputation Kay mentions car hire services,legal services,accountancy s
25、ervices,funeral services(?),consumer durables.Add vitamin pills,roofing services,pension funds,and All students are very familiar with the problem involved.Reputation Problem is that you want quality,but that quality takes time to manifest itself.All suppliers will guarantee satisfaction.How can you
26、 distinguish between them?If difficult then consumers will assume low quality and pay only low prices.If you can convince them you can obtain a premium price for quality assurance.Reputation Selling on reputation is saying we have made an investment in an asset so we have a lot to lose if we fail to
27、 satisfy.So you can trust us,but not the hit and run suppliers who sell on(low)price alone.How might it be done.Longevity(est.1768 sort of thing).Warranties.Advertising?Advertising and reputation Heavy advertising may be a way.Adv is a sunk cost which implies commitment to the service.There is somet
28、hing to lose.Evidence is that long term experience goods do have the highest adv/sales ratio(5%).(B.S.R.1992).Reputation and diversification Note for later,Reputation might be a basis for growth through diversification but Kay notes that an expensively created reputation can be damaged by unwise div
29、ersification when firms stray into areas they dont fully understand.Innovation as a distinctive capability A capacity for lowering costs or improving its products or introducing new products ahead of its competitors.Innovation by itself as a source of competitive advantage is actually quite rare.Inn
30、ovation is very difficult.It is uncertain,and it is hard to manage properly.There are no recipes.It can be difficult for firms which invest in R&D to secure or appropriate all the returns.So being able to do it well will undoubtedly give you a good edge.However many firms which seek competitive adva
31、ntage by this route fail.Often what appears to be competitive advantage based on a capability for innovation is actually based ultimately on architecture.e.g.Sony and GlaxoThe Value of Capabilities Distinctive capabilities generate success which attracts competitors.Their value depends on their sust
32、ainability and the appropriability of the value they generate.(see also Collis et al HBR 95)These in turn depend on the following factors:The Value of Capabilities Transparency:how easy is it to identify and understand?J.management techniques?Replicability:how easy to imitate/replicate?A team format

38、s.Key example is Peteraf(1993).Her approach is outlined below and summed up in this figure.Note she uses the term RENT common in US writing to connote the result of sustainable competitive advantage.The Linn example is from a student case study.PeterafmodelHeterogeneityEx-post limitsto competitionIm

41、OMPETITIVE ADVANTAGE THROUGH DIFFERENTATIONCompetitive Advantage a la Peteraf A firm is said to have a competitive advantage when it can:achieve rents:which requires resource heterogeneity between firms(some better bundles than others).enjoy rents that are not offset by the costs of achieving a supe
42、rior set of resources:which requires ex ante limits to competition for those resources.appropriate those rents for the firm:which requires imperfect resource mobility.sustain those rents:which requires ex-post limits to competition.Heterogeneity:Bundles of resources and capabilities are heterogeneou
43、s across firms.Heterogeneity implies that firms with superior resources/capabilities will earn superior returns.An important class of resources are those which are limited in the short run but may be renewed and expanded within firms that use them.Prahalad and Hamel(1990)argue that core competencies
44、-particularly knowledge-based resources-are enhanced as they are used because of learning.Ex-post limits to competitionForces which limit competition from imitators.These arise from sources already discussed:Imperfect imitability,replicability,and substitutabilityof resources/capabilities isolating
45、the firm from challengers.Ex ante limits to competition The source of a firms rents is a superior resource position.But imagine the situation before any firm has achieved this position.If many firms recognised its potential,a competitive struggle would ensue to obtain the resources and build the cap
46、abilities to occupy that position.This process would compete away all rents that could be obtained from occupying the position.For example,North Sea Oil fields.Manchester United team!National Lottery licence.Sony licence for transistor.The script for Four weddings and a Funeral Entrepreneurship and
47、rentSo a firm needs the foresight to acquire resources and build capabilities in the absence of such competition.This requires the presence of uncertainty and incomplete information and a willingness to take risks.The essence of successful ENTREPRENEURSHIP is of course foresight and taking advantage
48、 of uncertainty and incomplete information before someone else does.So what Peteraf seems to be saying here is simply that all rents begin with an entrepreneurial act.Which seems inherently sensible.Imperfect resource mobility This refers to the marketability or otherwise of the underlying resources
49、 and capabilities.See discussion above of appropriability.Thus good high street locations are important for retailers but competition means the rental costs reflect this fact.The value of the location is captured by the property owner not the retailer per se.Summing up on SCA The ultimate determinan
50、ts of success and failure?No recipes but the starting point is being cheaper,or better,or faster to market.The capabilities approach developed in the 90s looks to the development and deployment of a distinctive set of resources and capabilities.Summing up The value of distinctive capabilities lies i
