Before conducting full-functional continuity testing, an information security manager should verify that teams and individuals responsible for recovery have been identified and trained on their roles and responsibilities. This will ensure that the testing can be executed effectively and efficiently, as well as identify any gaps or issues in the recovery process. Risk acceptance by the business, copies of plans kept offsite and plans documented in simple language are all good practices for continuity management, but they are not as important as having clear roles and responsibilities defined before testing.

A BIA is an important part of Disaster Recovery Planning (DRP). It helps identify the impact of a disruption on the organization, including the critical systems and processes that must be recovered in order to minimize that impact. The BIA results are used to prioritize system restoration and determine the resources needed to get the organization back into operation as quickly as possible.

Residual risk is the remaining risk after all security controls have been implemented. It is important to measure the residual risk of an organization in order to determine the effectiveness of the security program and to justify continued investment in the program. A reduction in residual risk is an indication that the security program is effective and that continued investment is warranted.
