BDM Architecture Principle 2: Principle: BDM will consume GC and ESDC Enterprise Solutions/Services where appropriate and available. Statement: BDM will consume a GC or ESDC enterprise solution/service where it exists and meets all BDM mandatory and majority of non-mandatory functional and non-functional requirements, as well as, when there is a commitment and plan for long-term investment in sustainment and support. Rationale: With each decision to leverage an existing solution or service, BDM will inherit risks associated with the architecture, deployment, availability and operations of the solution/service. Solutions and services which may have not been designed for the scale required by BDM or lack appropriate investment commitments, product roadmaps and operational and support models, present a risk to the BDM Programme. Implications: • GC and ESDC Enterprise Solutions/Services will be evaluated against BDM requirements. If gaps are identified, it is expected that an investment and a project plan are put in place to close the gaps. • The architecture of the GC and ESDC Enterprise Solutions/Services will be evaluated for alignment and compatibility with the BDM solution architecture. • BDM may present opportunities to enhance or modernize certain enterprise solutions and services. Such opportunities will be identified as architecture options and presented to BDM-ARC.
