South Africa The system was set up to run in parallel with the existing live system allowing the business to compare results, thus giving them visibility and confidence. It was delivered on time which enabled the South African team to launch new products, increasing their revenue stream in a highly competitive market. United Kingdom The South African project was so successful that I lead a subsequent project to replace the UK’s system. The initial deployment to production took less than 2 weeks giving the business early and continued visibility of progress. The new system immediately saved Wonga £90,000pa in licencing fees and significantly decreased the failure rate of loan applications. Show less
