Successful ERP implementations are launched from successful ERP rollout strategies. Defining an ERP rollout strategy at the beginning of your implementation is crucial.

ERP rollout strategies include:

  • Big bang approach
  • Phased rollout
  • Parallel rollout
  • Hybrid approach

The big bang approach can save organizations time and money. Though big bangs eliminate the need for temporary interfaces that phased rollout approaches require, big bangs can be risky because testing is difficult if everything goes live at the same time.

With phased rollouts, organizations can realize business benefits sooner. Not only are smaller rollouts easier to test thoroughly, but phasing allows organizations to eliminate legacy systems sooner. Phasing also allows organizations to minimize risk because the rollout is divided into manageable phases. Phased rollouts allow your ERP system to evolve over time. They enable multiple rounds of planning and execution.

Parallel rollouts are best done in a test mode (rather than running two production systems simultaneously). With two production systems, neither system may have accurate data, and there may be confusion as to which is the system of record. Testing of the new system against the old system with the same data is a great testing exercise to do before go-live.

Hybrid approaches make sense for large ERP implementations across multiple business units. In a typical hybrid implementation, organizations may choose to use the big bang approach for smaller business units and a phased approach for larger business units.

All implementations take a phased approach at some point. For some, the next phase is a system upgrade done after the initial big bang. For others, the next phase may involve incremental  improvements to business processes.

There is no one-size-fits-all strategy for ERP implementations. Each organization and situation is unique. Working with Panorama can help you develop a the best rollout strategy for your unique needs.
