86 4.7.3 Technology Technology as an input to agency business covers technical equipment and software, such as: � desktop and server computing equipment (PCs, clusters, mid-range, mainframe etc.) � network and telecommunications infrastructure (switches, routers, cables, firewalls etc.) � commercial and in-house developed software (desktop and server, customised and uncustomised) � major office machines (photocopiers, scanners, fax machines) � scientific equipment � video conferencing and telephony equipment. For a more exhaustive list of technology inputs, refer to the AGA Technical Reference Model. 5301 Costs (technology) A – Acquisition B – Sustainment C – Operation D – Disposal 5302 Availability A – Utilisation B – Capacity C – Efficiency Australian Government Architecture Reference Models Version 3.0 53 Technology 5303 Reliability (technology) A – Age B – Wear C – Stability 5304 Compatibility (technology) A – Standardisation B - Customisation Figure 4-31: Technology Measurement Branch Understanding the performance relationships (effectiveness and efficiency) between technology as an input and the realisation of business initiative outcomes requires an understanding of technology costs, technology availability, technology reliability and technology accessibility.
Measurement Area Rationale Defined by [5301] Cost (technology) Technology cost is a key determinant in assessing the performance of technology investments and, through such assessments, of the overall performance of an agency in realising effective outcomes for government in an efficient manner. Technology cost is a multivariate attribute. Understanding the full cost of technology requires measuring the costs associated with acquiring the technology, sustaining the technology, operating the technology and disposing of the technology. A. Acquisition Quantitative measures of the non-labour attributable financial costs associated with the procurement of technology within an agency. Those costs include, but may not be limited to: � the purchase price of hardware � licensing costs for software � fee-for-service costs attributable to the acquisition of a technology capability. B. Sustainment Quantitative measures of the non-labour-based financial costs attributable to the maintenance of technologies. Costs recorded within this grouping may include, but are not limited to: � outsourcing contracts for the support and maintenance of technology � fee-for-service costs attributable to the maintenance of a technology capability � costs associated with the replacement of faulty technology subcomponents, such as a hard drive within a server cleaning and servicing costs for major office machines. C. Operation Quantitative measures of the non-labour financial costs incurred by an agency that are attributable to the operation of technology within the agency. Measurements within this grouping may include, but are not limited to: � proportion of electrical costs attributable to a technology � proportion of mechanical costs attributable to a technology (for example, air-conditioning) � value of the floor space occupied by piece of technology in a data centre facility. D. Disposal Quantitative measures of the non-labour financial costs incurred by an agency when a piece of technology is decommissioned and disposed of. Measurement indicators within this grouping may include, but are not limited to: � early termination penalties for support contracts � data cleansing fees � commissions payable to auctioneers.
