Ecosystem as Structure · Advanced Strategic Management

The core idea

An ecosystem is not a community of affiliated firms; it is the alignment structure of the multilateral partners whose interaction a focal value proposition requires. Strategy starts from the promised value, then maps the activities, actors, positions, and links needed to deliver it. Where partner alignment is intact, traditional strategy suffices. Where alignment must shift, the central question becomes who leads the realignment and how willing followers are secured. — after Adner (2017)

Put simply · The recipe that needs every ingredient.

A recipe promises a specific dish. To deliver it, every ingredient must be ready at the same time — flour, eggs, butter. The recipe is the value proposition. The ingredients are the partner activities. The kitchen is the alignment structure.

If the egg supplier is six months away from being ready, the dish cannot be served — no matter how good the butter is. That is co-innovation risk: your proposition depends on a partner who has not finished their part yet.

Most platform and ecosystem strategies fail not because the idea is wrong but because one ingredient is missing and nobody mapped the full recipe. Adner's framework forces you to draw the whole kitchen before you promise the dish.

The hero diagram

From value proposition to aligned ecosystem

Five steps move a focal firm from a promised value to a working ecosystem. Each step exposes a different alignment risk: missing activities, unwilling actors, contested positions, broken links, or absent leadership.

1

Define the value proposition

State the benefit the end customer is promised. The proposition, not the product, sets the boundary of the relevant ecosystem.
2

Map the activities

List the discrete actions required for the proposition to materialise. Co-innovation risk lives here: which activities are not yet ready?
3

Assign actors and positions

Name who performs each activity and where they sit in the flow. Adoption-chain risk lives here: which actors must change behaviour for the chain to hold?
4

Specify the links

Trace the transfers of material, information, money, and influence across positions, including those that bypass the focal firm.
5

Secure leadership and followership

Identify who guides the realignment and who accepts the follower role. Without willing followership, structure collapses back to the legacy configuration.

Ecosystem-as-Structure · Adner · Journal of Management 2017

Value proposition (the boundary-setter) · Activities · Actors · Positions · Links

Start with the value proposition and work backward to the alignment structure it requires; do not start with the partners.

Co-innovation and Adoption-Chain Risk · Adner

Co-innovation risk: partners' innovations not yet ready · Adoption-chain risk: partners must change their own behaviour

Your ecosystem is only as fast as its slowest required alignment. Identify which partner is the bottleneck.

Ecosystem-as-Affiliation vs Ecosystem-as-Structure · Adner

Affiliation: community of associated actors around a platform · Structure: configuration of activities for a specific value proposition

Use structure thinking when alignment must shift; use affiliation thinking when you are counting partners.

How to apply

When designing or diagnosing a multi-partner value proposition.

Write the value proposition in one sentence. Be specific about the promised benefit to the end customer. This sentence sets the ecosystem boundary.
List every activity the proposition requires. Include activities performed by partners, not just your own firm. Co-innovation risk lives here.
Assign an actor to each activity. Name the specific firm or role. Adoption-chain risk lives here: who must change their behaviour?
Draw the links. Which activities depend on which others? A broken link anywhere stops the proposition.
Identify the least willing follower. That actor is your binding alignment constraint. Address them first, not last.

Ecosystem as Structure: An Actionable Construct for Strategy.

Adner distinguishes ecosystem-as-affiliation (networks of associated actors) from ecosystem-as-structure (the activity alignment a specific value proposition requires). The ecosystem-as-structure view gives a vocabulary for diagnosing where alignment fails: missing activities, unwilling actors, unspecified positions, broken links, or absent leadership — each a different strategic problem.

You cannot fix an alignment problem by adding more partners. First, name what needs to be aligned.
