Following the successful migration, the IT room migration team should handover Business As Usual (BAU) management and support to the BAU support organisation.


Business as usual, the normal execution of standard functional operations within an organization, forms a possible contrast to projects or programmes which might introduce change.

Handover to BAU

The handover to BAU process will be triggered when the project scope is identified to cover the handover of the build environment to the support organisation. The support organisation may be internal or external. This process will be activated during the planning phase of the project and may span across the succeeding phases of execution and closure.

  • Preparation of the project plan addressing all requirements and timelines of handover to the support organisation.
  • Devise handover plan in accordance with contract.
  • Prepare or help the support organisation in preparation of support manuals, documents and other deliverables required for handover.
  • HLD, LLD, architecture diagram, test plan and standard operation procedure, AS-IS build document, physical location in IT room pictorial depiction of IT room, configuration details are examples of documents that project team will share with support organisation based on the project plan and specific requirements of the project.
  • Provide early life support for a maximum duration of 2 weeks.
  • Ensure that the support organisation is updated on known errors and issues.
