• broadband speeds offered,• competitive wholesale pricing,• projected initiatives to stimulate broadband take-up,• sustainability of the technological approach, • proposed re-use of existing infrastructure, and • impact of the proposed solution on competition in the market.Value for money can be achieved in several ways, for example, by:• Writing procurement specifications in output terms, enabling suppliers to consider and recommend cost-efective solutions that meet the requirements.• Ensuring that the requirements are met but not exceeded (bidders may propose, for example. building a network in an area that is not considered to be a priority). Making network coverage maps available will be vital as part of this process.• Introducing longer-term incentives into the contract to ensure continuous cost and quality improvements are made to the broadband network throughout its lifetime.• Optimizing the cost of delivering the network over a longer-term, such as 15 years or more.Use of existing infrastructure Bidders should be encouraged to re-use existing infrastructure (where this is fit for purpose) to avoid infrastructure duplication and reduce the amount of public subsidy required. The government should consider seting up a national database containing information on the availability of existing infrastructure that could be re-used for broadband roll-outs.48 Trends in Telecommunication Reform 2016 Figure A1.1: Overview of competitive dialogue process Initial/refined/final outline requirements Repeat of Close Dialogue Supplier evaluation and reduction criteria as defined by purchases and published as part of the process Evaluate supplier responses Update requirements Supplier dialogue work streams,meetings, clarifications, supplier updates Requirement validation Buyers’internal review Source: Analysys Mason, 2015
