World Views
An overview of Soft Systems Methodology and example use of WorldViews was presented.
It was agreed to develop:
- PQR - What, How and Why;
- Root Definitions,
- Perspectives
- CATWOE Analysis, (Customers, Actors, Transformation, WorldView, Owner and Environment) for Services.
Stakeholder Analysis and Relationships
A literature search failed to find useful definitions of Stakeholder Analysis in SeBOK or the INCOSE Handbook. However, definititons in Wikipedia have been used as a basis for identifying stakeholders, their relationship to the Service, and analysing their degree of influence, support and other 'dimensions'. This has been applied to three of the group's Use Cases.
Literature Update
Two papers of interest have been issued by yhe Cambriodge Service Alliance:
This relates to the Variables work carried out in the WG used to identify different types of Service.
This relates to the Case Study on Rental Electric Vehicles and different approaches/business models for their roll-out.
Definitions
Further work has been done in harvesting definitions from glossaries of standard texts including
- DoDAF (Service) 'A mechanism to enable access to a set of one or more capabilities'
- Open Group (Server) 'An application component which responds to requests from a client'
The DoDAF use may be regarded as the Service Interface. The Open Group use of 'Server' is from Service Oriented Systems where components which are largely software based are used to build the Service System
Definitions of the term 'Service' from the glossary of various sources now cover the following: Service (Intangible), Service Use, Service System, Service Specification, Service Agreement, Service Interface, Service Component. These are related, together with additinal terms in an ERD that provides a rich picture of Service Provision, Engineering and Management
Links to STEM
Following correspondance with the INCOSE UK Technical Director, the possible links between the Service work and STEM were discussed. STEM requirements and the potential use of the WG Use Cases will be investigated.
Possible Papers
Papers for submission to IS2016 and as a preliminary ASEC2015 were considered. These could cover the Use Cases, Dimensions, and/or Definitions.
Plan
Progess against the plan will be reviewed at the next meeting.
