Chartwell’s years of experience is embedded in the reference models that it has developed for its own use and the use of its clients. These reference models represent patterns that have emerged within specific types of services in many jurisdictions. They provide significant value to clients by minimizing the time required to develop a comprehensive business design or enterprise architecture.

Three widely adopted standard reference models developed by Chartwell are the public sector reference models. While designed for the complexity of delivering the public sector services, these models can definitely be applied to the challenges of the private sector as well:

The MRM ("Municipal Reference Model") has been used by over 20 Canadian Municipalities to support a wide-range of enterprise level business and IT challenges.

The PSRM ("Public Service Reference Model") has been adopted by the Province of Ontario and is used by Management Board Secretariat to ensure alignment of change initiatives to service improvement objectives.

The GSRM ("Governments of Canada Strategic Reference Model") as being developed in the BTEP (Business Transformation Enablement Program) in Treasury Board Secretariat.

All of the standard public sector reference models (“MRM”, “PSRM”, and “GSRM”) use a common formal “service concept”. The GSRM in particular provides a set of standard service patterns that can be leveraged and rapidly customized to any public sector initiative to describe and analyze both business and ICT services. There are a number of benefits of this approach:

• As the service concept and service patterns have been widely used on other projects throughout the three jurisdictions, there is a great opportunity for efficiency gains through the harvesting and reuse of existing business and ICT service designs.
  

• The service patterns support the identification of common patterns and act as an organizing analytic framework for detailing business and ICT requirements and for integrating and aligning other frameworks i.e. Information Technology Infrastructure Library (ITIL) etc.
  

• The service patterns come equipped with a standard set of processes and service performance metrics. The use of these standards will support a common view towards service Key Performance Indicators (KPIs) and cost modeling components.
  

• The use of the patterns is efficient and supports quality and standardization, ‘edit’ versus ‘discovery mode’.
  
  

One of the strongest benefits of using a structured business modeling approach is its support for the formal evaluation and assessment of alternative scenarios and the gaining of consensus by stakeholders.

A key distinguishing factor in the use of public sector reference models is the ability to integrate all models or views of the enterprise. We feel that this approach is essential to ‘taming the complexity’ of enterprises to be manageable, optimized and flexible through change.
