 | Objectives The programme aims to establish a federated view of all government agencies' enterprise architectures to optimise government ICT assets for greater cost savings or avoidance. | Introduction: The objective of the Whole-of-Government Enterprise Architecture (WOG EA) is to enable the Government to optimise its ICT assets by rigorously analysing and identifying strategic opportunities from its various lines of businesses, business information, software applications and technology investments.
Background: Enterprise Architecture (EA) in the Government started in 2002 with a focus establishing a Technical Architecture (TA). The Service Wide Technical Architecture (now renamed as Singapore Government – Technology (ICT) Architecture or SG-TRM) is a set of technology standards, product registers and best practices, which guides agencies in the construction of ICT systems, with the objective of enabling inter-agency systems interoperability. In 2007, a set of artefacts (collectively known as the Singapore Government Enterprise Architecture or SGEA) that broadly lists business functions across government agencies, supported by relevant data standards, common systems and services, and technologies was established to achieve enterprise goals. It includes the following deliverables which will provide guidance for Government EA practitioners: Business Reference Model (SG-BRM); Data Reference Model (SG-DRM); Solution Reference Model (now renamed as the Singapore Government – Application Reference Model or SG-ARM); and Technology Reference Model (SG-TRM). In addition, a methodology for agencies to develop their agency-wide EA called MAGENTA was established. This provides the Government with a methodology that is relevant to its agencies when developing and using EA. An EA practitioner's certification programme was also introduced in mid-2006. In 2009, an EA Pilot was conducted with 6 related agencies using the artefacts from the SGEA to determine the potential benefits that can be derived with a cross-agency EA exercise. A total of 17 ICT opportunities were identified, with 12 of these being inter-agency opportunities, and 3 being demand aggregation opportunities. The 12 inter-agency opportunities can be translated into 12 feasible shared systems.
Programme Details The WOG EA programme aims to achieve the following outcomes: - Identify opportunities for end-to-end service integration for a seamless government, leading to greater synergy and efficiency.
- Identify shared systems that can be used by multiple government agencies to minimise duplicative efforts.
- Improve clarity on application resilience requirements to achieve robust solution designs.
- Improve impact analysis on technology adoption to attain better technology planning and policy development.
- Improve transparency of Whole-of-Government (WOG) initiatives and government agencies' various ICT investments, as well as their policy alignment with business goals to reach better investment decisions.
A Central EA Repository (Singapore Government – Central Repository for EA or SG-CREATE) for service-wide use was established. Under this repository, the current SGEA artefacts are translated into reusable modelling objects that can be used by agencies to model their own EA. SG-CREATE also have the capabilities to capture agencies' ICT Portfolio information (that comprises of ICT Programmes and Projects), Systems and Applications Portfolio, and support these ICT Infrastructure Portfolios. The repository allows agencies to have an analytical view of their ICT landscape and investments at the WOG level. The next step for the WOG EA Programme is to focus on key business functions that span across multiple agencies to identify inter-agency synergies and opportunities. SG-CREATE database will be populated with agencies' ICT Portfolio and EA information, so that better ICT investment analytics can be derived to help identify opportunities that can be leveraged upon to achieve WOG strategic goals effectively.
