2. Cleo Carris and Jim Feenan 12 th December, 2007 www.btwholesale.com WBC Collaboration “We want to engage with customers to help us all understand what will be delivered at each stage, capture any missing, changed or delayed requirements and ensure a positive Customer Experience” To do this we: Hold frequent bilaterals Encourage direct customer involvement Provide “War Room” Support Flexibly reprioritise each 90 day development cycle Add and amend requirements with our customers We need to take this approach forward into the End to End testing world.

3. Cleo Carris and Jim Feenan 12 th December, 2007 www.btwholesale.com WBC – Providing a Positive Customer Experience “We are aiming for a Smooth and Seamless CE delivered through joint testing & collaborative development and communications” We do this with: A CE roadmap planned and measured throughout the trial, launch and in-life stages of WBC. Use measurable CE targets to share underlying test results with customers, rather than getting bogged down in reams of test results. We focus on delivering a positive E2E CE for BTW, the CP and their EU customers. We help customers deliver a marketing and sales message based on the CE delivered by the product.
