Parallel running sounds like a safety net. In reality, it's one of the most common and most expensive mistakes in ERP implementation.

In this episode, Pete and Nirav are joined by Emily Browning — an IT leader in manufacturing — to break down exactly why running your old system alongside your new ERP almost always backfires.

We talk through:

  • Why data duplication quickly becomes data chaos — and you lose your single source of truth
  • The real impact on your teams when you ask them to do everything twice during go-live 
  • What "just in case" actually signals to the rest of the business 
  • Why phased or staggered go-lives rarely work for fully integrated ERP systems 
  • How keeping the old system alive delays ROI and muddies the business case
  • Practical tactics for driving adoption — from post-go-live training to accountability dashboards

If you're approaching go-live and leadership is asking about parallel running, this episode gives you the arguments (and the confidence) to push back.
