66 markets they analysed。 Online book sales – Amazon (wrong); Books。 
 (right) – Copiers; Xerox (wrong); IBM (right) – PCs; IBM/Apple (both 
wrong); Micro Instrumentation Telemetry Systems (MITS) introduced its 
PC the Altair; a 400 kit; in 1974; followed by Tandy Corporation (Radio 
Shack) in 1977。 
In fact the most pelling evidence from all the research was that nearly 
half of all firms pursuing a first…to…market strategy were fated to fail; while 
those following fairly close behind were three times as likely to succeed。 
Tellis and Golder claim that the best strategy is to enter the market 19 years 
a。。er pioneers; learn from their mistakes; benefit from their product and 
market development and be more certain about customer preferences。 
INDUSTRY ANALYSIS 
Aside from articulating the generic approach to business strategy; Porter’s 
other major contribution to the field was what has bee known as the 
Five Forces theory of industry structure (Figure 12。2)。 Porter postulated that 
the five forces that drive petition in an industry have to be understood 
as part of the process of choosing which of the three generic strategies to 
pursue。 The forces he identified are: 
。 Threat of substitution: Can customers buy something else instead of 
your product? For example; Apple; and to a lesser extent Sony; have 
laptop puters that are distinctive enough to make substitution 
difficult。 Dell; on the other hand; faces intense petition from dozens 
of other suppliers with near…identical products peting mostly on 
price alone。 
。 Threat of new entrants: If it is easy to enter your market; start…up 
costs are low and there are no barriers to entry such as IP (intellectual 
property) protection; then the threat is high。 
。 Supplier power: The fewer the suppliers; usually the more powerful 
they are。 Oil is a classic example; where less than a dozen countries 
supply the whole market and consequently can set prices。 
。 Buyer power: In the food market; for example; with just a few; powerful 
supermarket buyers being supplied by thousands of much smaller 
businesses; they are o。。en able to dictate terms。 
。 Industry petition: The number and capability of petitors is one 
determinant of a business’s power。 Few petitors with relatively 
less a。。ractive products or services lower the intensity of rivalry in a 
sector。 O。。en these sectors slip into oligopolistic (see also Chapter 7; 
Economics) behaviour; preferring to collude rather than pete。

You can see a video clip of Professor Porter discussing the Five Forces model 
on the Harvard Business School website (h。。p://harvardbusinessonline。

SHAPING STRATEGY – TOOLS AND 
TECHNIQUES 
While Porter’s Five Forces approach to strategy formulation is; as far as 
business schools are concerned at least; the standard starting point; there 
are a number of other tools that an MBA needs to be familiar with。 Some 
pre…date Porter; some overlap; while others home in on specific issues。 Like 
many such tools; they overlap with those used in marketing and in this book 
you will find SWOT (strengths; weaknesses; threats and opportunities) and 
perceptual mapping covered in Chapter 3; Marketing。 
These are the main tools and techniques an MBA will be expected to 
know and understand。

Ansoff’s Growth Matrix 
Igor Ansoff; while Professor of Industrial Administration in the Graduate 
School at Carnegie Mellon University; published his landmark book; Corporate 
Strategy (1965); where he explained a way of categorizing strategies 
as an aid to understanding the nature of the risks involved。 He invited his 
students to consider growth options as a square matrix divided into four 
segments。 The axes are labelled with products and services running along 
the ‘x’ axis; starting with ‘present’ and ‘new’; and markets up the ‘y’ axis 
similarly labelled (Figure 12。3)。 
Figure 12。3 Ansoff’s Growth Matrix 
Existing products New products 
Existing markets Market penetration Product development

Concentric 
Conglomerate 
Ansoff then went on to assign titles to each type of strategy; in an ascending 
scale of risk (you can find out more about the matrix at  
strategyvectormodel 》 Theories 》 Ansoff Matrix): 
。 Market penetration; which involves selling more of your existing products 
and services to existing customers – the lowest…risk strategy。 
。 Product/service development; which involves creating extensions to 
your existing products or new products to sell to your existing customer 
base。 This is more risky than market penetration; but less risky than 
entering a new market where you will face new petitors and may 
not understand the customers as well as you do your current ones。 
。 Market development involves entering new market segments or pletely 
new markets either in your home country or abroad。 
。 Diversification is selling new products into new markets; the riskiest 
strategy as both are relative unknowns。 Avoid; unless all other strategies 
have been exhausted。 Diversification can be further subdivided into 
four categories of increasing risk profile: 
– Horizontal diversification (entirely new product into current market)。 
– Vertical diversification (move backwards into firms supplier’s or 
forward into customer’s business)。
Strategy 271 
– Concentric diversification (new product closely related to current 
products either in terms of technology or marketing presence but 
into a new market)。 
– Conglomerate diversification (pletely new product into a new 
market)。 
Boston Matrix 
Developed in 1969 by the Boston Consulting Group (see above); this tool 
can be used in conjunction with the life…cycle concept (see Chapter 3; 
Product/Service Life Cycle) to plan a portfolio of product/service offers。 
The thinking behind the matrix is that a pany’s products and services 
should be classified according to their cash generating or consumption 
ability against two dimensions: the market growth rate and the pany’s 
market share (Figure 12。4)。 Cash is used as the measure rather than profit; 
as that is the real resource used to invest in new offers。 The objective then 
is to use the positive cash flow generated from ‘cash cows’; usually mature 
products that no longer need heavy marketing support budgets; to invest 
in ‘stars’; that is; fast…growing; usually newer products; positioned in 
markets in which the pany already has a high market share – usually 
newer markets。 ‘Dogs’ should be disinvested and ‘question marks’ limited 
in number and watched carefully to see if they are more likely to bee 
stars or dogs。
