A strategic dependency exists when an organisation relies on another participant, capability or resource that is important to its success and difficult to replace.
Dependencies are normal in ecosystems. In fact, ecosystems work because organisations depend on one another for things they cannot or do not want to provide themselves.
The strategic issue is not dependency itself.
It is how important the dependency is, how easily it can be replaced and who has more power if the relationship changes.
A business may depend on a partner for technology, distribution, customer access, specialist expertise, data, infrastructure or a critical component. If alternatives are readily available, the dependency may matter operationally but have little strategic significance.
If alternatives are scarce, switching is costly or the business has made investments specific to that relationship, the dependency becomes much more important.
Research on ecosystem advantage reflects this tension. Ecosystem specific investment can strengthen complementarity and value creation, while increasing dependency, bottleneck exposure and the risk of being held up by another participant.

When does a dependency become strategic?
Three things matter most:
Importance. How much of your value proposition depends on it?
Replaceability. How easily could you find another way to perform the same role?
Switching cost. What would it cost in time, money, capability or customer disruption to change?
A dependency becomes more strategic as importance rises and replaceability falls.
Imagine two software suppliers.
One provides a standard accounting tool that can be replaced within a few weeks.
The other provides the interface through which most customers access your service.
Both are dependencies.
Only one may materially affect your strategic position.
This is why counting suppliers or partners tells you very little. The real question is:
Which relationships would be difficult to lose?
How can strategic dependency create power?
Because dependence is rarely perfectly balanced.
If you depend heavily on another participant and they can replace you more easily than you can replace them, they have an advantage in the relationship.
That can become bargaining power.
They may be able to influence prices, access, commercial terms or the rules governing the relationship.
Consider developers in a platform ecosystem.
A developer may invest heavily in building products specifically for one platform. The platform also benefits from having good developers, so there is mutual dependence.
But the dependence may not be equal.
If the platform can replace one developer more easily than the developer can replace access to the platform’s customers, the platform has the stronger position.
The research shows this clearly. Platform owners may control rules, architecture and access while complementors make ecosystem specific investments. That asymmetry can create bargaining power for the platform owner.
But power has limits.
If the stronger participant repeatedly changes terms or captures too much value, partners may reduce investment, use several competing ecosystems or leave.
So dependency can create power, but exploiting that power too aggressively can weaken the ecosystem that produced it.
How is strategic dependency different from a bottleneck or control point?
The concepts are connected, but they describe different things.
Strategic dependency asks:
What do we rely on that would be difficult to replace?
Bottleneck asks:
What is currently limiting the system?
Control point asks:
Where is influence concentrated?
The same participant can occupy all three positions.
Suppose a specialist supplier provides a critical component.
If you cannot easily replace it, you have a strategic dependency.
If its limited production capacity is restricting growth, it is also a bottleneck.
If its scarcity allows the supplier to influence prices and terms, it may also occupy a control point.
But those conditions do not always appear together.
A dependency can be important without constraining current performance. A bottleneck may exist without anyone gaining useful power from it. And an organisation can control customer access without being a resource on which production depends.
Keeping the concepts separate helps reveal what is actually happening.
Are dependencies always a weakness?
No.
Trying to eliminate dependency would undermine much of the point of an ecosystem.
Specialisation allows different participants to become very good at different things. Complementarity then allows those capabilities to create more value together than they could separately.
The result is interdependence.
The problem arises when the architecture creates dependency without enough alternatives, safeguards or reciprocal commitment.
Research on ecosystem advantage warns against architectures built around too many specialised connections because they can make change expensive and create bottlenecks.
There is therefore a balance.
Too little dependency can mean shallow relationships that are easy to copy.
Too much dependency can make participants vulnerable.
The aim is not independence.
It is productive interdependence without unacceptable exposure.
How should a company manage strategic dependencies?
Start by identifying them.
For each important dependency, ask:
How important is it to the value proposition?
How many credible alternatives exist?
How long would replacement take?
What investments have we made that cannot easily be reused elsewhere?
How dependent is the other participant on us?
That final question matters because dependency is relational.
If both sides would suffer equally from separation, the relationship may be reasonably balanced.
If one side can walk away easily while the other cannot, the balance of power is different.
Possible responses also differ.
You might develop another supplier, redesign an interface, support several platforms, create common standards, make investments more transferable or deepen the relationship where mutual commitment creates real advantage.
The goal is not to remove every dependency.
It is to know which dependencies create value, which create vulnerability and which give someone else power over your future choices.
