Tirupati Auto Ltd. runs its new ERP in parallel with the old system for two months. In the context of ERP implementation, which statement is correct?

Parallel running lowers risk because both systems operate together and their outputs can be compared, with the old system as fallback. However, it costs more and burdens staff through duplicate processing. It does not require shutting down the old system first and is not the cheapest option.

  1. AIt reduces implementation risk because outputs can be compared, but it increases cost and workload through duplicate data entryCorrect
  2. BIt is the cheapest strategy because only one system is maintained
  3. CIt requires the legacy system to be shut down before the ERP starts
  4. DIt means only one module is tested at a single location

Explanation

Parallel running lets the company compare results of both systems and fall back if the ERP fails, which lowers risk. The price is double effort and higher cost. The other options describe big-bang or pilot approaches, or are simply untrue.
