I was studying the ERP implementation strategies recently, and here is a problem related to the big bang approach that I feel a little bit hard to solve. Could you help me to explain the advantages and disadvantages associated with the decision to implement the new system using the big bang system conversion approach? Could you explain it in terms of data warehousing implications, business culture, implications and disruption to operations? I need some idea about it.

Phased adoption is like bringing up lighting with a dimmer: areas of the organization and workflows come on, additively. For parallel adoption, the legacy and incoming systems run in parallel.
