Sundaram Textiles Ltd. plans to move from its legacy systems to a new ERP. The CIO decides to switch off the old systems on a fixed date and let all departments start using the new ERP on the very next day. Which ERP implementation strategy is this?

This is big-bang implementation. The company retires its legacy systems on one fixed date and all departments start using the new ERP immediately. Phased rollout moves in stages, and parallel running keeps both systems live together, which the scenario does not describe.

  4. DPilot module implementation

Explanation

In a big-bang approach the whole organisation moves to the new ERP on one cut-over date and the old system is retired at once. A phased approach moves module by module or location by location, and a parallel run keeps both systems running together for some time, so neither matches the scenario.
