29. Control Cost Drivers

30. Reconfigure the Value Chain
• Reconfiguration of the value chain
presents the opportunity to fundamentally
restructure a firm’s cost, compared to
settling for incremental improvements.
• By altering the basis of competition in a
way that favors a firm’s strengths, it may
change the important cost drivers in a way
that favors a firm.

31. Steps in Strategic Cost Analysis
1. Identify the appropriate value chain and
assign costs and assets to it.
2. Diagnose the cost drivers of each value
activity and how they interact.
3. Identify competitor value chains, and
determine the relative cost of competitors
and the sources of cost differences.
4. Develop a strategy to lower relative cost
position through controlling cost drivers or
reconfiguring the value chain and/or
downstream value.

32. Cost Focus

differentiation in the Value Chain, rather
than on products or markets only
• Differentiation base on buyers’ value,
not only difference that buyers do not
value
• Should consider the cost of
differentiation
