Lessons from the Horizon Scandal
Horizon is the flawed accounting system, introduced by the Post Office in 2000, that led to the wrongful conviction of hundreds of sub-postmasters. What lessons can we learn from this when implementing new accounting software?
Horizon endeavoured to automate accounting processes at Post Office branches. However, it led to accounting shortfalls that they were unable to be reconciled due to the lack of paper-based evidence. The sub-postmasters were blamed, and the system’s bugs were not investigated at the time. This highlights the need for IT governance when a new IT system is introduced.
When implementing a new IT system, you must:
- Always go through rigorous system testing of its functionality and reliability.
- Ensure that mechanisms are in place for immediately detecting system errors and there is the capacity to provide a quick solution to them.
- All users (staff, customers, suppliers) have a clear way to report issues
- Allow users and stakeholders to give feedback to identify potential problems early
