It's not always the "big bang" scenario that causes the problem

Business Continuity Management: An Overview

Plan Development

A business continuity plan should include:

1) Development of the detailed response to an incident

2) Formulation of plans that support the response to an incident and enable critical functions to continue to provide service (external / internal)

The degree of detail and flexibility of response of individual companies’ plans will differ, largely dependent upon their size and the nature of their business.

The Business Continuity Plan should be produced on a plan structure that is suited to the organisation. There may be a requirement for divisional / location-based plans and it is important that these integrate into the high level plan for the organisation.

Where appropriate, the plan may be developed using specialised software.
