VDML for Business Architects: Part 8 of 11, Value Contribution Analysis

Please see the post for VDML for Business Architects: Part 1 of 11, for the introduction to this series of posts.  This part describes the nature of value streams and their impact on value propositions.  A value stream is the sequences of activities and value contributions that feed a value propositions for particular customers.  A value stream may have many tributaries that converge on a value proposition.  A capability method may participate in multiple value streams.
1.    Value chain stages that aggregate value measurements

Value chain stages (based on Porter’s value chain) are collaborations (capability methods) that delegate to more operationally specific capability methods.  Each value chain stage contributes the aggregated values of the activities and capability methods it engages.  The aggregations extend to delegated capability methods to the extent the model is completed or until contributions of further delegations are estimated or derived from actual operational measurements. This provides meaningful value measurement contributions that are estimated without added cost and time required to develop a more robust model.
2.    Value proposition reflects a customer perspective

A value proposition does not only capture the value measurements associated with the delivery of a product or service, but the measurements are translated to levels of customer satisfaction and weighted according to customer priorities for overall expected satisfaction.  Consequently, it expresses the values that the enterprise expects to deliver to the customer from the customer’s perspective.
3.    Satisfaction level computations

A value proposition component (a line item in a value proposition) provides for the translation of a value measurement to a customer satisfaction level.  This computation will depend on the value type and the target market.
4.    Weighted satisfaction levels

Each value proposition provides for a weight on each value type reflecting the level of interest of customer(s) in the target market.  These provide for computation of a weighted average for an overall value proposition level of customer satisfaction.
5.    Activity-level value contributions

VDML captures value contributions of individual activities to be aggregated up value streams in support of value proposition computations.  The need to assess value contributions at the activity level of activities was recognized by Michael Porter as a limitation of the generally accepted approach to value chain modeling.  Activities can be aligned to actual business operations for capture of actual measurements or development of estimated measurements.
6.    Unit of production value impact

Measurements are based on a unit of production within each capability method.  This enables computation of averages where activity flows converge or diverge.  It also enables the contributions of a capability method engaged by delegations to be appropriately adjusted according to the fraction of units of production contributed by the engaged capability method.  VDML supports these adjustments to the value measurements returned from a delegation.
7.    Value proposition impact analysis

When changes to a capability method affect value measurements, these changes will propagate through all of the value streams in which it participates to update all of the associated value propositions.  A display can trace these value streams to identify the affected value propositions and show the impact.
8.    Multiple market segment value propositions

A value stream may feed different value propositions for different customers or target markets.  Each value proposition then has satisfaction computations and importance weights appropriate to the particular customer or market segment.
9.    Value streams with shared capability methods

Capability methods can be shared across value streams and lines of business for economy of scale and enhanced agility.  Value and performance measurements depend on each context and the scenario.
10. Enterprise-level performance optimization

Capability methods may be engaged by multiple lines of business with different performance measurements, costs and defect rates. Changes to capability methods can be immediately evaluated across all affected value streams and lines of business to measure, balance and optimize adjustments from an enterprise perspective from individual activities to value propositions.
