  1. Increasing understanding of Tax Credit error: Using discrete event simulation to identify where errors enter the process Laura GlasstoneTuesday 22nd September 2009

  2. Outline • What are Tax Credits? • Original work request • HMRC and Lean • What is simulation? • What If scenarios • What has modelling achieved? • Questions

  3. What are Tax Credits 2 elements of Personal Tax Credits: • Child Tax Credit (CTC) • Working Tax Credit (WTC) • Introduced in 2003

  4. What are Tax Credits 2 elements of Personal Tax Credits: • Child Tax Credit (CTC) • Working Tax Credit (WTC) • Introduced in 2003 • £20 Billion paid out in 2007-08 • 4% of total revenue collected • Why am I using simulation?

  5. What is Lean • Generic process management philosophy • Developed by Toyota and known as lean since 1990’s • 5 step process where the principle is to create more value with less work

  6. What is Simulation • Discrete event simulation is a technique that mimics the operation of a real or proposed system. • Simulation models are time based and take into account all the resources and constraints. • Simulation also builds in the randomness. • Simulation can be used to show the eventual real effects of alternative conditions and courses of action

  7. “What if” scenarios • Observe the impact of experiments and changes to the system • Check all claims as they come in • Check all attached documents and use them as/when they come in • Increase the number of staff • Decrease time taken to complete tasks

  8. What has modelling achieved? • Explore “what if” scenarios. Are interventions effective? • Given an overview of the entire claim process • Identified resource usage • Identified queues/ areas of interest • Testing the timeliness of the agreed HMRC targets

  9. Questions?
