Objectives of the research
Customer needs:Documentation of how OIS wouldinteract with external systems
Especially MRP systemsProcess models and interfaces
16.1.2007 6
Research problems
1. How is OIS positioned in a typical hospital systems architecture and how it interacts with external systems?
2. How the external MRP systems interact with OIS?
3. What is required from an MRP Web Service from the OIS’s point of view?
16.1.2007 7
Phases of the empirical study
Building a model of OIS and its connections to external systems
Reviewing the model together with our client
Describing the models of interaction processes between OIS and material/equipment management systems in more detail
Based on the first model and theory
Defining interfacesServices, operations, inputs and outputs

Results
Research questions answered1. Diagram of OIS and its connections to
other systems2. BPMN diagrams describing interaction
between OIS and material/equipmentmanagement systems
3. Interface descriptions

Conclusions
Model of OIS’s position in the architectureof hospital systems
Multitude of different inter-connected systems
Five diagrams of how OIS would interactwith MRP systems
Models differ from the common MRP processes(e.g. RosettaNet)
Interface descriptions derived from the process models
Interfaces as such are quite simple
