SSE Meeting 25

INCOSE UK Service Systems Engineering Working Group

Meeting: 6 June 2017, Keynsham, Bristol

Attendees

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

Comparison of Service Representations

Various case studies, source documents, and findings from the group publications were compared and contrasted to see:

• which techniques, processes, representations, etc. were seen to be useful in one studies
• which could be identified across different case studies
• which could be usefully applied to other case studies.

The data used

• IS2016 paper Understanding Services Understanding Stakeholders
• ASEC2016 submitted paper:

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.
