The Service Value Chain

Six activities, many arrangements

The service value chain is a set of six interconnected activities that an organization performs to transform demand and opportunity into value through products and services. It is a model of what the organization does, not a prescribed sequence.

  • Plan - understand the shared vision, current state and direction; set strategy, policy and portfolio.
  • Improve - drive continual improvement across all activities, products and services.
  • Engage - understand stakeholder needs, maintain relationships, be transparent, and keep the loop of feedback open.
  • Design and transition - ensure products and services continually meet stakeholder expectations for quality, cost and time to market.
  • Obtain/build - ensure service components are available when and where needed, and that they meet agreed specifications.
  • Deliver and support - ensure services are delivered and supported according to agreed specifications and stakeholder expectations.

A value stream is a specific combination of these activities that creates value for a consumer. Because the activities interact, one value stream might use engage → design and transition → obtain/build → deliver and support, while another uses engage → improve → plan. The same activity can appear several times in one value stream.

Worked example: a request for a new laptop. Engage captures and clarifies the request; design and transition confirms the standard build; obtain/build acquires and configures it; deliver and support hands it over and closes the request. No step requires the plan activity, which is why value streams are drawn rather than assumed.

Traps: treating the six activities as a fixed left-to-right pipeline; assuming every value stream must use all six; confusing the value chain (a model) with a value stream (a real path); assigning engage only to pre-sales or improve only to one team.

Rule of thumb: read a scenario and ask which activity is doing the work described - plan produces direction, improve produces change, deliver and support keeps things running.
