Testing & Exercises Guide

Why Test Your Plans?

Even the most carefully crafted business continuity plan can fail when it matters most. Testing identifies gaps, validates assumptions, and builds muscle memory so your team can respond effectively under pressure.

ISO 22301 requires organizations to conduct exercises to ensure their plans are effective. But beyond compliance, testing is simply good practice — you don't want to discover your plan doesn't work during an actual crisis.

Key Insight: Testing is not about finding that everything works — it's about finding what doesn't work while you still have time to fix it.

Types of Exercises

There's a spectrum of exercise types, from simple reviews to full-scale simulations. Start simple and progress to more complex exercises over time.

Checklist / Document Review

Easiest

Individual or small group review of plans to verify accuracy of contact information, procedures, and resources.

Duration: 1-2 hours | Participants: 1-3 | Frequency: Quarterly

Tabletop Exercise

Recommended Start

Discussion-based exercise where participants talk through their response to a hypothetical scenario. No actual systems or processes are activated.

Duration: 2-4 hours | Participants: 5-15 | Frequency: Semi-annually

Walkthrough / Drill

Intermediate

Participants physically walk through their response procedures. May include physically moving to alternate locations or demonstrating specific tasks.

Duration: 2-8 hours | Participants: 10-30 | Frequency: Annually

Functional Exercise

Advanced

Tests specific functions or systems in a realistic environment. May involve activating backup systems, failover procedures, or alternate facilities.

Duration: 4-24 hours | Participants: 20-50 | Frequency: Annually

Full-Scale Simulation

Most Complex

Multi-function, multi-organization exercise that simulates a real incident as closely as possible. Often includes external agencies and partners.

Duration: 1-3 days | Participants: 50+ | Frequency: Every 2-3 years

Planning an Exercise

A successful exercise requires careful planning. Here's a simple framework:

1. Define Objectives

What do you want to test or validate? Be specific about success criteria.

2. Choose Scenario

Select a realistic scenario that challenges your plans and participants.

3. Prepare Materials

Create scenario injects, timeline, and any props or documentation needed.

4. Brief Participants

Explain objectives, ground rules, and expectations before starting.

5. Conduct Exercise

Facilitate the exercise, inject scenario elements, and observe responses.

6. Debrief & Document

Gather feedback, document findings, and create an improvement action plan.

Common Findings

Exercises consistently reveal similar types of issues across organizations:

Outdated contact information
Unclear roles and decision-making authority
Missing or inaccessible documentation
Untested recovery procedures that don't work as expected
Communication breakdowns between teams
Dependencies that weren't documented
