Chapter 4 - Strategy Maps and Strategic Groups (PC Industry Context)

A strategic group is a cluster of companies within an industry that tend to behave similarly because they invest in the same subsets of Key Success Factors (KSFs).
Firms in the same strategic group occupy nearby positions in strategic space and thus become primary competitors with each other.
Competitive KSF analysis (e.g., Figure 4.20) helps identify firms that are very similar to one another on key competitive dimensions; a strategy map adds a visual representation of their relative positions.

Competitive KSF analysis identifies similarities among competitors across key dimensions.
A strategy map uses two selected KSFs as axes to reveal relative positions and to visualize competition more clearly.
Strategy maps are built from the same KSFs but emphasize spatial relationships and relative strengths/weaknesses.

Step 1: Identify the KSFs in the industry and measure each competitor on these dimensions as objectively as possible.
Step 2: Choose two of the KSFs and plot the competitors on a graph using these dimensions as the axes.
- Convention: place the desirable condition toward the outer end of each axis.
- Example KSFs in PC industry: Innovation and Cost Control (Unit Cost as a measure of cost competitiveness).
- Axis orientation example:
- Horizontal axis corresponds to Unit Cost, with lower costs placed toward the right end (i.e., the axis is oriented so that lower unit cost is higher on the axis).
- Vertical axis corresponds to Innovation, with higher innovation toward the top.
- Therefore, the upper-right portion of the graph represents the most desirable combination: low unit cost and high innovation.
- Notation for this orientation can be described as: the axis values increase toward the desirable ends.
Step 3: Locate each competitor on the graph according to their measured values for the two KSFs, and then draw a circle at each position.
- The size of each circle should represent the relative size of the competitor (e.g., market share).
- The resulting map reveals overlaps, gaps, and clusters of competitors (strategic groups).

In the PC industry example, two KSFs identified are:
- Innovation (higher is more desirable, plotted toward the top)
- Unit Cost (lower unit cost is more desirable, plotted toward the right)
Observation on the map:
- There is no company currently occupying the upper-right quadrant (high innovation and low unit cost).
- Dell and others have pushed the frontier of low-cost production while maintaining an average level of innovation.
- Apple is significantly higher on the innovation dimension but less advanced in unit manufacturing (i.e., higher on innovation, lower on cost efficiency).
The graph (referred to as an industry map) would plot each company (e.g., Dell, Sony, Acer, Lenovo, HP, Gateway, Apple) with a circle size proportional to market share.
Figures mentioned:
- Competitive KSF analysis: Figure 4.20
- PC Industry Strategy Map: Figure 4.21

Let KSFs be a set of two chosen dimensions: $KSF1$ and $KSF2$.
For each competitor $i$, denote:
- $UnitCosti$ = measure of unit cost (lower is better for $KSF1$).
- $Innovationi$ = measure of innovation (higher is better for $KSF2$).
To place these on a two-axis map, define coordinates:
$Xi = -\text{UnitCost}i,$
$Yi = \text{Innovation}i.$
The strategy map point for competitor $i$ is:
$Pi = (Xi, Y_i).$
Desirable region: upper-right quadrant where both $Xi$ and $Yi$ are high (i.e., low unit cost and high innovation).
Circle size for each competitor reflects market share $si$ (i.e., area ∝ $si$).

Strategy maps provide a visual tool to compare competitors on two critical KSFs and to identify strategic groups.
The placement of competitors helps one (a) identify gaps (e.g., potential high-innovation, low-cost leaders), (b) spot primary competitors within the same strategic group, and (c) assess mobility and positioning opportunities.
Real-world interpretation (PC industry): Dell and peers emphasize cost competitiveness with moderate innovation; Apple leads in innovation but lagges in unit-cost efficiency, illustrating different strategic orientations within the same industry.

Strategy maps connect to foundational principles of competitive positioning by translating multi-dimensional KSFs into a two-dimensional space for easier interpretation.
Identifying strategic groups informs strategic choices about where to compete and how to allocate resources across R&D, production, and supply chain investments.
The approach highlights ethical and practical implications of competition, including potential focus on reducing costs through supply chain optimization or increasing value through innovation—decisions with broader market and consumer impact.
