Conclusion: This month, the large outsourcing agreement between Thales and the Department of Defence/Airservices Australia has been the subject of discussion. Whilst the contract value is high, more significant are the complex project objectives which resulted in a lengthy contract negotiation period. Initially, agencies involved anticipated an off-the-shelf solution to replace national air traffic control systems. However, it became apparent that a customised solution to support system functions was required, given the large and technically complex nature of the project. In order to reduce risks associated with contract failure, a two-year negotiation period was undertaken to ensure delivery responsibilities and specifications were well-defined. Project oversight and monitoring frameworks, vendor incentives to stay within project budgets and meet fulfilment targets were also described in detail within agreements. Although concerns were flagged regarding the delay in finalising this agreement, extra care was warranted given the critical functions the system will support, as well as the high value and complex system foundations. By adopting this approach, all parties have a sturdier agreement which can provide value for money, performance incentives, frameworks for contract execution as well as a better chance of project success.
