The rules are under review and subject to change.
1. Rule requirement
1.1 Reuse of Defence ICT
1.1 Defence ICT shall be reused where available. Where appropriate reusable ICT is available but not used justification for this decision must be provided. Use of legacy standards is not enough justification on its own for not reusing ICT
- Reuse of Cross Government ICT and enterprise agreements
2.1 Cross Government ICT shall be reused where available in accordance with the Cross Government ICT Strategy
2. Rationale
This rule embodies “service above self”. Decisions made from an enterprise-wide perspective have greater long-term value than decisions made from any particular organisational perspective.
Maximum return on investment requires decision makers to adhere to enterprise-wide drivers, policies and priorities. No minority group will detract from the benefit of the whole. Some organisations may have to concede their own preferences for the greater benefit of the entire enterprise.
