Preparedness and continuity

Preparedness is the knowledge, plans, stocks and capacities that let governments, services, businesses and households respond to a disaster and recover. Continuity planning applies the same idea to the critical functions of an organization. This page sets out how preparedness is built and how it decays, how capacity is measured, and what evidence serves the authorities and operators who must be ready.

01In brief

The short answer.

Disaster preparedness is the knowledge, plans, stocks and capacities that let governments, services and households respond to and recover from disasters. Continuity planning applies the same discipline to an organization's critical functions. Preparedness decays between events unless plans, stocks and training are maintained and tested.

04The question

Preparedness and continuity: how the risk develops.

Organizational capacity and continuity. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Stocks and capacities age

Prepositioned supplies expire, equipment breaks, trained staff move on and contact lists go out of date. Preparedness that is not maintained loses value quietly between events.

Mechanism

Plans assume conditions

Plans rely on roads, power, communications and staff being available. When a disaster removes those conditions, plans written for normal circumstances stall.

Mechanism

Coordination is built before it is needed

Agencies that have never worked together lose time agreeing roles during a response. Standing arrangements, shared procedures and joint exercises save that time.

Mechanism

Critical functions depend on others

A hospital, water utility or government office continues only if its suppliers, staff and premises do. Continuity planning that ignores these dependencies fails when they fail.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Contingency planA plan prepared in advance for a specific hazard or scenario, setting roles, resources and actions.
PrepositioningPlacing relief supplies near areas at risk before a disaster to shorten delivery time.
Critical activityAn activity whose interruption would cause unacceptable harm, which continuity planning protects.
06Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

10Core questions

What experts ask.

Specialists in preparedness and continuity focus on whether arrangements hold when tested.

  • Which functions must continue in a crisis, and what do they depend on?
  • Do plans reflect how people and systems actually behave under stress?
  • How are responsibilities divided between agencies, and where do gaps and overlaps sit?
  • How are staff, supplies, facilities and data kept available when normal arrangements fail?
  • How is preparedness sustained between disasters, when attention and budgets move elsewhere?
11Mechanisms and drivers

Why plans fail at the seams.

Plans often assume that people will be available, that communications will work, that suppliers will deliver and that other agencies will do their part. In real events, staff are themselves affected, networks are congested or down, suppliers face the same disruption and agencies interpret their roles differently. Failures cluster at interfaces: between levels of government, between public and private operators, and between emergency services and the organizations that run water, power and health care.

Continuity depends on knowing dependencies in advance, on redundancy and substitutes for critical inputs, and on people who have practised their roles together. Preparedness also decays: staff move on, contact lists age and equipment is not maintained. Regular exercise and review are what keep a plan alive.

12Methods and data

How the evidence is built, and where it stops.

  1. 01

    Capacity assessment

    Structured review of plans, resources and arrangements. Self-assessment tends to overstate readiness.

  2. 02

    Dependency mapping

    Mapping inputs to essential functions with operations research. Hidden dependencies often emerge only in events or exercises.

  3. 03

    After-action review

    Structured learning from events and exercises. Lessons are often recorded but not implemented.

  4. 04

    Comparative case research

    Comparing how similar organizations fared, with social and behavioural science. Context limits how far findings transfer.

14Questions

Questions and answers.

What is disaster preparedness?
The knowledge and capacities developed by governments, response organizations, communities and individuals to anticipate, respond to and recover from likely, imminent or current disasters, in UNDRR usage.
What is business continuity planning?
Planning that identifies an organization's critical activities, what they depend on and how they will continue or be restored within set times after disruption.
Why test plans?
Because plans contain assumptions about people, resources and conditions that only a test or real event reveals. Exercises find the gaps while there is time to fix them.
What is the difference between preparedness and continuity?
Preparedness covers the capacity to respond to and recover from disasters generally; continuity focuses on keeping an organization's essential functions running during disruption.
Can preparedness be measured?
Partly. Plans and resources can be counted, but performance under stress is best revealed by exercises and real events, which is why the platform links assessment with exercise evidence.
Does the platform review my organization's plan?
No. It publishes guides and evidence that organizations can use for their own review. Technical assistance, where offered, is scoped separately under written terms.
