1. Business Continuity Institute (BCI), Good Practice Guidelines (GPG), 2018 Edition. Section 8.4.2, "Crisis Communication Plan," states that the plan should define "key messages that reflect the organization’s values and commitment to its stakeholders." This directly supports the principle that communications must be consistent with the organization's core identity. The guidelines also emphasize the need for authorized spokespeople (contradicting B) and providing factual, specific information (contradicting D).
2. ISO 22301:2019, Security and resilience — Business continuity management systems — Requirements. Clause 7.4, "Communication," requires a systematic process for communication with interested parties. This structured approach implies alignment with the organization's overall policies and objectives (Clause 5.2), which are expressions of its core values and culture.
3. Coombs, W. T. (2014). Ongoing crisis communication: Planning, managing, and responding (4th ed.). Sage Publications. Chapter 6, "Crisis Response Strategies," emphasizes that the selection of a communication strategy should be guided by the need to protect the organization's reputation, which is built upon its perceived character and values. Inconsistent messaging undermines this reputational asset.
