Determinants - externalities that determine what a business does, how it operates etc. These are external factors that include: cultural and social, market and competitive, legal and regulatory, etc.
Enterprise strategy - business: vision, mission, goals, strategies and plans (product, market, organisation), cases, governance and compliance, measures etc
Enterprise operations - business: services, processes, rules, information (objects, documents, data etc.), organisation, facilities etc. and change iniatives
Systems and facilities - including applications and services, technologies and system services, facilities and internal utilities. The systems area can be further divided into business services and systems and technology services and systems.
Suppliers - externalities that determine the products, services, standards a business can use e.g. technology products, services and standards; product channels; real estate and facilities. This section includes details of all provisioning and agreements.
Effectively the external constraints are the determinants and the suppliers; the goals come from the strategy and the operations, systems and facilities - represent a solution set (i.e. designed to the meet the goals based on the constraints).
Notes on the above
- I have tried to avoid using two loaded terms in the above "architecture" and "framework". I use Enterprise to encompasses things that may not be "businesses" per se.
- In each of the middle three areas there may be change initiatives (for transformation or optimisation driven from that level).
- Business requirements derive largely from the Enterprise Strategy and Enterprise Operations.
- User acceptance is the confirmation that the Systems and Facilities meet the Requirements i.e. represents a boundary condition and/or illustrates compliance with a set of constraints (e.g. requirements).
- The division into into business services and systems and technology services and systems may be increasingly hard to work with in a way that is useful for decision making for most enterprises e.g. splitting a GPS function used by a business into its: application, infrastructure (device) and service (e.g. satellite) components may in practice be difficult. This will increasingly be the case as consumer and external services and components are integrated to support Enterprise operations. Similiarly in the past some technology reference models have identified somewhat layers of technology that are increasingly irrelevant in practice with many devices e.g. operating systems, graphics presentation, file and database, etc. are not that useful if the device is an appliance. These division are probably useful distinctions for technologies operated internally by an enterprise. But a decision is 1st required that operating these technologies internal is to be desired or required.
