Who does what when AI joins in?

AI changes how a service is delivered when people, software, and partner organizations take on different parts of the work.

Look beyond one person and one tool

A service usually connects several participants. Customers, employees, and partner firms may all use AI. Understanding their collaboration requires looking at the resources they share and the rules that shape what each participant can do.

What the paper contributes

Our framework describes service networks in which humans and AI systems act together. It explains how the division of work depends on the situation and can evolve as participants change their capabilities and expectations.

Human–AI collaboration extends beyond a pair

People, AI systems, and human–AI hybrids bring resources into a shared service. Their roles depend on the task and the rules around them.

Rules and norms

Laws, policies, and shared practices shape the interaction.

Human–AI hybrid

Human agencyAI agency

Roles configured for the task: who decides, acts, and stays in control.

Human actor

The task is performed through human agency.

AI actor

The task is performed through AI agency.

Actors provide access to resources
Actors experience value in use

Hybrid intelligent service

Actors combine resources to create value together.

Resources

Skills, knowledge, data, and infrastructure

Adapted from Figure 2 of Bartelheimer et al. (2025), CC BY 4.0. Labels and layout are simplified; the two exchanges apply to each participating actor. A hybrid ecosystem needs at least one human–AI hybrid, but not necessarily every actor type shown. This is a conceptual model.

Following a customer request

Illustrative example: an AI assistant prepares an answer, an employee checks it, and a partner supplies information needed to resolve the request. The service depends on all of those contributions and on agreements about access, responsibility, and disclosure.

A question to take into practice

Who is acting, what resources can they use, and what rules apply? Mapping those relationships is one way to use the framework when discussing a new AI service. This is a practical application of the concept, rather than a method tested in this paper.

About the study

Research approach

This is a conceptual study: we bring existing theories together to explain a problem they address separately. We combine research on human–AI collaboration with service ecosystem theory and research on agency, the capacity of people and software to act and influence outcomes. The aim is to explain how collaboration changes across a whole service network.

How we developed the framework

We connected concepts from these research streams into a framework covering participants, their resources, and the rules governing their interactions. We then worked through scenarios, including elderly care and IT customer support, to examine whether the framework could describe different forms of collaboration. This process led to propositions about how human and AI roles develop and affect the wider network.

What the study can tell us

The framework provides a way to analyze who does what when AI enters a service. The scenarios illustrate its use; they are not field trials. Whether particular arrangements improve outcomes still needs empirical testing, especially in settings where human–AI collaboration is less established.
