Technology Forecast

ea3-infraEA3 artifact I-4: Technology Forecast

The Technology Forecast supports and relates to the I-3 Technology Standards Profile.  The Technology Forecast documents expected changes in any of the standards listed in the I-3 artifact, where future changes appear to be happening or about to happen.

  • Captures expected changes in technology related standards and conventions
  • Identifies critical technology standards, their fragility, and impact of changes to the architecture
  • Contains specific predictions about the availability of emerging standards, and relates to specific System/Application (SA) framework elements

Technical Standards Profile

ea3-infraEA3 artifact I-3: Technical Standards Profile

The Technology Standards Profile is a listing of business services and associated technologies that are accepted by the enterprise as being a primary or secondary standard.  Further detail can be added regarding particular types of standards.

Configuration Management

This best practice involves an ongoing governance process and uses the network inventory, capital equipment inventory, and other EA artifacts to maintain a accurate picture of the hardware, software, and other equipment are active in the business and technology operating environment.

Configuration Management in EA documentation is very important, because the transition between current and future architectures is ongoing.

Stakeholder requests for changes to the architecture should be done via a formal process that is overseen by the Chief Architect, using something like the EA Change Request Form.
EA tools often have built-in CM capabilities.

Network Diagram

ea3-infraEA3 artifact I-1: Network Diagram

The Network Diagram shows the physical connections between the enterprise’s voice, data, and video network… including external Wide Area Networks (WANs) and Local Area Networks (LANs)… also called ‘extranets’ and ‘intranets.’

Software License Inventory

ea3-sysEA3 artifact A-11: Software License Inventory

Software Asset Management (SAM) enables strategic infrastructure planning, prevents over-licensing and under-licensing, and identifies over-deployment of hardware and its associated costs.

It also allows the IT department to control exactly what software an employee can access and significantly reduces the opportunity for users to introduce unlicensed software on to networks.

Application Inventory

ea3-sysEA3 artifact A-10: Application Inventory

IT application inventories are simple tools that can facilitate the process of operational IT governance. They are defining the overall IT infrastructure and serve to describe current and future functions and related tools.

Application Maintenance Procedure

ea3-sysEA3 artifact A-9: Application Maintenance Procedure

Documentation of how:

  • the organization develops and formally documents system maintenance policy;
  • the organization system maintenance policy addresses: -purpose; -scope; -roles and responsibilities; -management commitment; -coordination among organizational entities; and -compliance;
  • the organization disseminates formal documented system maintenance policy to elements within the organization having associated system maintenance roles and responsibilities;
  • the organization develops and formally documents system maintenance procedures;
  • the organization system maintenance procedures facilitate implementation of the system maintenance policy and associated system maintenance controls; and
  • the organization disseminates formal documented system maintenance procedures to elements within the organization having associated system maintenance roles and responsibilities.
  • the organization defines the frequency of system maintenance policy reviews/updates;
  • the organization reviews/updates system maintenance policy in accordance with organization-defined frequency;
  • the organization defines the frequency of system maintenance procedure reviews/updates; and
  • the organization reviews/updates system maintenance procedures in accordance with organization-defined frequency.

Enterprise Service Bus Diagram

ea3-sysEA3 artifact A-8: Service Bus Diagram

The service bus diagram shows the logical relationships between web-based information services, in this case showing a detailed diagram of services that interact via standard protocols and interfaces that promote platform-independent data interchanges.

Application Performance Matrix

ea3-sys
EA3 artifact A-6: Application Performance Matrix

The Application Performance Matrix lists the metrics that are important with regard to reliability, availability, and maintainability.

  1. Specifies the quantitative characteristics of system:
    • Hardware/software
    • Interfaces
    • Communication components
  2. Identifies both current and future parameters.
  3. Includes all relevant technical performance characteristics, for instance:
    • Mean Time Between Failure
    • Restart Rate
    • System Initialization Time
    • Data Transfer Rate
