value chain analysis
Definition
Michael Porter published the Value Chain Analysis in 1985 as a response to criticism that his Five Forces framework lacked an implementation methodology that bridged the gap between internal capabilities and opportunities in the competitive landscape. This framework focused on industry attractiveness as a determinant of the profit potential of all companies within that particular industry. However, significant differences in performance exist between companies operating within the same industry that can be explained either by the company's participation in a successful strategic group or by a firm's specific competitive advantages.
Value Chain Analysis helped identify a firm's core competencies and distinguish those activities that drive competitive advantage. The
cost structure of an organisation can be subdivided into separate processes or functions assuming that the cost drivers for each of these activities behave differently. Porter's strength was to condense this activity based cost analysis into a generic template consisting of five primary activities and four support activities. The nine activity groups are:
Primary activities:1. inbound logistics: materials handling, warehousing, inventory control, transportation;2. operations: machine operating, assembly, packaging, testing and maintenance;3. outbound logistics: order processing, warehousing, transportation and distribution;4. marketing and sales: advertising, promotion, selling, pricing, channel management;5. service: installation, servicing, spare part management; Support activities:6. firm infrastructure: general management, planning, finance, legal, investor relations;7. human resource management: recruitment, education, promotion, reward systems;8. technology development: research & development, IT, product and process development;9. procurement: purchasing raw materials, lease properties, supplier contract negotiations. By subdividing an organisation into its key processes or functions, Porter was able to link classical accounting to strategic capabilities
by using value as a core concept, i.e. the ways a firm can best position itself against its competitors given its relative cost structure, how the composition of the value chain allows the firm to compete on price, or how this composition allows the firm to differentiate its products to specific customer segments.
Assessment
Pros:Value Chain Analysis provides a generic framework to analyse both the
behaviour of costs as well as the existing and potential sources of differentiation.
Porter emphasised the importance of (re)grouping functions into
activities to produce, market, deliver and support products, to think about relationships between activities and to link the value chain to the understanding of an organisation's competitive position.
The value chain made clear that an organisation is multifaceted and
that its underlying activities need to be analysed to understand its overall competitive position. An organisation's strengths and weaknesses can only be identified in relation to the profiles of its direct competitors. Competitive advantage is derived from an integrated set of decisions on these key activities.
The Value Chain model was intended as a quantitative analysis. It can
also be used as a quick scan to describe the strengths and weaknesses of an organisation in qualitative terms.
With the Value Chain Analysis, Porter tried to overcome the limitations
of portfolio planning in multidivisional organisations. The concept of Strategic Business Units stated that businesses within a conglomerate should act independently while headquarters should be responsible only for budgetary decisions to be based on a business unit's position in the overall portfolio. Porter used his Value Chain Analysis to identify synergies or shared activities between Strategic Business Units and to provide a tool to focus on the whole rather than on the parts.
Cons:The quantitative analysis is time consuming since it often requires
recalibrating the accounting system to allocate costs to individual activities. Porter provided qualitative guidance for a quantitative exercise. His analysis began with identifying the relevant activities that lead to competitive differences and are significant enough to influence the organisation's overall cost base.
The Value Chain Analysis should be accompanied with a customer
segmentation analysis to mix the internal and external view. A feature or product provides the firm with a differentiating competitive advantage only if customers are willing to pay for it. Customer value chains need to be analysed to determine where value is created.
The Value Chain is used to analyse a firm's position in relation to its
direct competitors with the assumption that rivalry drives profitability. This excludes other assumptions such as customer bonding in Alexander Hax's delta model.
The Value Chain Analysis was developed to analyse physical assets in
product environments. Other authors amended the model to accommodate intangible assets and service organisations.
obtain competitive advantage through value chain linkages
nr. linkage example
1 separate individual activities within the firm’s value chain industry leader in marketing and sales
2 interlinked primary activities in the firm’s value chain
add quality inspections on materials to increase customer value
3 interlinked secondary activities in the firm’s value chain
restructure organisation to foster learning in all relevant activity areas
4 vertical linkages within the industry value system
develop close relationships with suppliers to improve new product development

cost driver categories
• structural: related to strategic choices that drive costs
• executional: related to an organization’s ability to execute successfully
© provenmodels
structural cost drivers (related to organizational choices)
• scale: investment size in manufacturing, R&D and marketing
• scope: degree of vertical integration• experience: learning based on previous repetitions of
current work• technology: process technologies used at each step
in value chain• complexity: broadness of product line
executional cost drivers (related to organizational skills)
• work force involvement: participation; empowerment; commitment to continuous improvement
• capacity utilization: given scale choices on plant construction
• plant layout efficiency: compared to current norms
• product configuration: design or formulation effectiveness
• exploiting linkages with suppliers/customers: in relation to the value chain
key ideas behind cost drivers
• volume is usually not the best way to explain cost behavior
• more useful to explain cost position in terms of structural choices and executional skills
• not all strategic cost drivers are equally important all the time but most of the time some driver are very important
objective value chain analysis
• the objective is to analyse competitive advantage by disintegrating an organisation into discrete activities or processes and examine how each activity contributes to the organisation’s relative cost position or the customer’s comparative willingness to pay.
the analysis provides:
• insight into why the firm does or does not have added value;• a way to identify opportunities to improve added value;• an understanding how added value may change over time.

value chain analysis process
process:1. setup: classify an organisation’s activities based on the value chain. Single out individual activities which:
• Have different economics;• Have a high potential impact of differentiation;• Represent a significant or growing proportion of costs.
2. cost analysis: managers examine the costs associated with (the most important) activities to understand why and how their cost base differs from competitors. Defining relevant cost drivers helps to estimate competitor’s positions and to assess the own organisation’s flexibility;
3. value analysis: managers analyse how each activity generates customer willingness to pay. Customer willingness often varies per customer segment;
4. strategic decision making: consider changes in activities so that costs are lowered or customer willingness is increased. Identify linkages, relationships between value activities, within the chain. The more complex the linkage the higher chance it will provide a competitive advantage. The competitor’s profiles need to be taken into account when repositioning oneself.

tips for value chain analysis
focus on the important activities; those that matter to the strategic position;make a clear distinction between annual recurring cost and one time investments;keep track of all assumptions that underline the allocation of costs over the activity groups;use sensitivity analysis to validate the assumptions underlying the value chain analysis in order
to assess which assumptions really matter;value chain analysis allows for the inclusions of multiple drivers per activity. only include drivers that vary across competitors;do not focus on differences between total cost levels, but on costs per activity. Activities provide
competitive advantage;research should focus on customers willingness to pay for an activity as part of a product’s
profile instead of only a customers desire;reduce the list of customer needs to a manageable number.

analysing industry’s profit pools
• estimate the total size of the industry profit pool using aggregated data and assumptions
• estimate the distribution of the profit pool- use you own firm’s profit structure per activity;- concentrate on the largest firms first- start with the focused one’s- estimate the contributed of relevant SBU’s within conglomerates- sample the smaller firms
• validate finding by matching the sum of the distribution and the total size
