Andrew Farncombe, Alan Crawford, John Davies, Iain Cardow, Simon Wright

==Review of Healthcare Case Studies==

===Healthcare sources===
Two sources of Case Studies were considered.
* NHS CHAIN - Contact, Help, Advice, Information Network. [[http://www.chain-network.org.uk/chain/index.html]] 
* US Institute of Healthcare.  [[http://www.ihi.org/resources/Pages/CaseStudies/default.aspx]]

Both of these contain many Case Studies, but they are about medical or organisational decisions and the effect on patients.  None were found that related to the Health Care Service and how it was provided.

===INCOSE IS2017===
Three papers were tagged a Healthcare:
* van der Watt: Healthcare Facility Commissioning – The Transition of Clinical Services
* Uger: Comprehensive Approach to Systems Engineering Capability Development in GE Healthcare.
*Beasley and O'Neil.  Selling Systems Engineering by Searching for the Sweet Spot.

Having reviewed these:
* van der Watt describes a new hospital and bringing it into operation.  It uses SoS terminology - so talks about a National Health System rather than a Service.  This paper should be good for comparison of a Systems of Systems view and a Service view.

* Uger: is about Systems Engineering Capability Development not Healthcare.

* Beasley and O'Neil.  Is about Selling Systems Engineering not Healthcare.

== Example Service Representation ==
Simon W presented work looking at how to define/represent/model a service to maintain military vehicles.  This work has been carried out for an overseas customer over the last year.
===Findings ===
Compared with Systems:
* The same principles, processes and tool used for defining/developing systems are needed for developing systems 
* Context diagram is key
* In a layered model, the Service-layer is on top of the Product layer
* The Service life-s=cycle is different
* Stakeholder analysis is needed and is more important for Services than for Systems.
* In contrast to systems, the key stakeholder outside the service.  eg in Healthcare the patient is outside the Service, but in a Systems model the patient could be inside the system.

===Way forward ===
* Simon to send brief analysis/model for comment
* All to study and compare with previous work.

== Next Meeting ==

Monday 5 June 2017 10-30 to 14-30, Rolls-Royce, Filton, Bristol.
