Business Impact Analysis (BIA)

A structured process that identifies critical business functions and quantifies how quickly disruption harms them, producing recovery time and recovery point targets that later strategy and plan decisions depend on.

Related: Recovery Time Objective (RTO), Maximum Tolerable Downtime (MTD), Critical Business Function
Maximum Tolerable Downtime (MTD)

The longest period a function can be unavailable before the organization suffers unacceptable harm, such as regulatory breach, irreversible financial loss, or loss of reputation or life safety.

Related: Recovery Time Objective (RTO), Recovery Point Objective (RPO)
Recovery Time Objective (RTO)

The target elapsed time within which a function, system, or process must be restored after disruption so the organization stays within its maximum tolerable downtime.

Related: Maximum Tolerable Downtime (MTD), Recovery Point Objective (RPO)
Recovery Point Objective (RPO)

The maximum acceptable volume of data, expressed as time, that may be lost in a disruption; it sets how frequently backups or replication must occur.

Related: Recovery Time Objective (RTO), Data Backup and Replication
Critical Business Function

A process whose interruption quickly threatens the organization's viability, legal compliance, safety, or contractual obligations, and which therefore receives priority for continuity resources and testing.

Related: Business Impact Analysis (BIA), Dependency Mapping
Dependency Mapping

Documenting the upstream and downstream relationships a function relies on, including suppliers, applications, facilities, people, and utilities, so that hidden single points of failure become visible.

Related: Critical Business Function, Single Point of Failure, Interdependency
Single Point of Failure

Any component, supplier, person, or location whose loss alone halts a critical function, making it a priority for redundancy, cross-training, or alternate arrangements.

Related: Dependency Mapping, Redundancy
Interdependency

A mutual reliance in which two or more functions, teams, or organizations each need the other to operate, so recovery of one is blocked until the other is at least partly restored.

Related: Dependency Mapping, Supply Chain Continuity
Impact Threshold

A defined level of harm, often expressed in money, time, or legal exposure, at which a disruption moves from tolerable to unacceptable and triggers escalation or continuity activation.

Related: Maximum Tolerable Downtime (MTD), Risk Assessment
Risk Assessment

The process of identifying threats and hazards, estimating likelihood and consequence, and comparing results against tolerance so continuity effort is directed where it matters most.

Related: Business Impact Analysis (BIA), Risk Appetite, Threat and Hazard Identification
Risk Appetite

The amount and type of risk leadership is willing to accept in pursuit of objectives, which guides how much redundancy, spending, and residual risk a continuity program tolerates.

Related: Risk Assessment, Residual Risk
Threat and Hazard Identification

Systematic cataloguing of plausible disruptive events, such as cyberattack, flood, fire, pandemic, or supplier failure, used to test whether strategies address realistic scenarios.

Related: Risk Assessment, Scenario-Based Exercise
Continuity Strategy

The chosen approach for protecting a function within its recovery targets, for example alternate site, manual workaround, redundant supplier, or accepting the risk with documented rationale.

Related: Recovery Time Objective (RTO), Workaround, Reciprocal Agreement
Alternate Site

A pre-identified location where people and systems can operate after loss of a primary facility; it may be hot, warm, or cold depending on how quickly it can be made productive.

Related: Hot Site, Cold Site, Reciprocal Agreement
Hot Site

A fully equipped alternate facility with hardware, connectivity, and data already in place, enabling recovery within hours but carrying high ongoing cost.

Related: Warm Site, Cold Site, Alternate Site
Warm Site

An alternate facility with some infrastructure and connectivity ready but requiring configuration, data restoration, or equipment delivery before it can support production work.

Related: Hot Site, Cold Site
Cold Site

A shell facility providing space, power, and basic environment only, requiring substantial setup before use; cheapest to maintain but slowest to activate.

Related: Hot Site, Warm Site
Reciprocal Agreement

An arrangement in which two organizations agree to host each other's operations during disruption; inexpensive but risky because both parties may be affected by the same event.

Related: Alternate Site, Mutual Aid Agreement
Redundancy

Deliberate duplication of capacity, such as spare servers, dual network paths, or cross-trained staff, so failure of one element does not stop the function.

Related: Single Point of Failure, Failover
Failover

The automated or manual switch from a failed component to a standby one, such as moving processing to a secondary data center or cluster node.

Related: Redundancy, Recovery Time Objective (RTO)
Workaround

A temporary manual or alternative method used to deliver a function's output while normal systems or facilities are unavailable, often slower or with reduced controls.

Related: Continuity Strategy, Manual Procedure
Manual Procedure

Documented paper-based or offline steps that staff can follow when automated systems are down, including forms, approvals, and later reconciliation of records.

Related: Workaround, Business Continuity Plan (BCP)
Supply Chain Continuity

Planning that ensures critical goods and services keep flowing when a supplier fails, through qualified alternates, buffer stock, or contractual continuity requirements.

Related: Interdependency, Single Point of Failure
Business Continuity Plan (BCP)

The documented set of procedures, roles, and resources an organization follows to keep or restore critical functions during and after a disruption.

Related: Crisis Management Plan, Manual Procedure, Plan Activation
Crisis Management Plan

The portion of continuity documentation covering leadership decision-making, communications, and stakeholder management during an incident, complementing operational recovery procedures.

Related: Business Continuity Plan (BCP), Crisis Communications, Incident Command Structure
Crisis Communications

Prepared messaging, channels, and spokespeople used to inform employees, customers, regulators, and media accurately and consistently during disruption.

Related: Crisis Management Plan, Stakeholder Notification
Plan Activation

The defined trigger and authority by which leadership formally puts the continuity plan into effect, including who may declare an incident and how staff are notified.

Related: Business Continuity Plan (BCP), Incident Command Structure
Incident Command Structure

A clear assignment of roles and reporting lines during an incident, typically separating operations, planning, logistics, and communications so decisions are not duplicated or missed.

Related: Plan Activation, Crisis Management Plan
Stakeholder Notification

The procedure and contact data used to alert employees, key customers, suppliers, and authorities when an incident occurs, including escalation timing and backup channels.

Related: Crisis Communications, Call Tree
Call Tree

A cascading contact method in which each person notifies a small set of others, speeding mass notification while providing confirmation that messages were received.

Related: Stakeholder Notification
Exercise Program

The scheduled cycle of activities, from plan walkthroughs to full simulations, that builds competence and reveals gaps before a real disruption occurs.

Related: Tabletop Exercise, Full-Scale Exercise, After-Action Report
Tabletop Exercise

A discussion-based session where participants talk through a scenario and their responses, testing plans, roles, and assumptions without moving people or systems.

Related: Scenario-Based Exercise, Functional Exercise, Exercise Program
Functional Exercise

A drill that actually performs specific recovery tasks, such as restoring a server or activating an alternate site, to verify that procedures work under realistic conditions.

Related: Full-Scale Exercise, Tabletop Exercise
Full-Scale Exercise

The most realistic test, involving actual relocation or live failover of people and systems, coordinated with external parties, and typically the most costly to run.

Related: Functional Exercise, Exercise Program
Scenario-Based Exercise

A test built around a specific plausible threat, such as ransomware or loss of a key supplier, chosen to probe whether strategies handle that particular disruption.

Related: Tabletop Exercise, Threat and Hazard Identification
After-Action Report

The written record of an exercise or real incident, capturing what happened, what worked, what failed, and corrective actions with owners and due dates.

Related: Corrective Action Plan, Exercise Program
Corrective Action Plan

A tracked list of fixes arising from exercises, audits, or incidents, each with an accountable owner, deadline, and status review until closure is verified.

Related: After-Action Report, Plan Maintenance
Plan Maintenance

The ongoing process of reviewing and updating continuity documentation so it reflects current staff, systems, suppliers, and risks rather than becoming stale.

Related: Plan Review Cycle, Version Control, Corrective Action Plan
Plan Review Cycle

The scheduled frequency, often annual or after significant change, at which plans are formally re-examined and re-approved by accountable management.

Related: Plan Maintenance, Trigger-Based Review
Trigger-Based Review

An unscheduled plan update forced by a material change such as a merger, new critical system, site move, or major incident, rather than by the calendar.

Related: Plan Review Cycle, Plan Maintenance
Version Control

Practice of labeling, dating, and archiving plan documents so responders always use the current approved copy and can trace what changed and who approved it.

Related: Plan Maintenance, Plan Distribution
Plan Distribution

Controlled issuance of plans to those who need them, including offline or out-of-band copies, so responders can access procedures even when primary networks fail.

Related: Version Control, Business Continuity Plan (BCP)
Residual Risk

The risk that remains after continuity strategies and controls are applied, which leadership must knowingly accept, reduce, or transfer.

Related: Risk Appetite, Risk Assessment
Maturity Assessment

An evaluation of the continuity program against a capability framework or standard, producing a baseline and roadmap for improvement rather than a pass/fail result.
