During a merger or acquisition, the last thing you want is a disruption to your services. Wary customers, already watching for potential impacts to leadership or service level, may see even a slight disruption as their cue to look elsewhere. Maintaining business continuity during the transition doesn’t just keep operations running; it builds customer trust, protects your brand, and gives you a competitive edge.

Mergers and acquisitions are on the rise as organisations look to expand into new markets and add products and services. Growth offers opportunity, but it also brings complexity and risk that can disrupt operations. To manage these risks effectively, you should engage business continuity and operational resilience teams from day one.

Postponing resilience planning until after the deal closes causes confusion. Overlapping systems, shifting reporting lines, and unclear roles create gaps in business continuity plans. Disruptions become more likely. Service quality drops, and customers look to competitors.

When pursuing growth through M&A, investigate business continuity capabilities as part of your due diligence and selection criteria. By the time the transaction completes, you should already understand the target organisation’s BCM program, including its key risks, dependencies, and recovery capabilities. Build an interim plan to align processes and address gaps, reducing disruption and supporting a smooth integration.

Why M&A Puts Resilience at Risk

Even well-planned mergers can strain your operations if the merging companies have different cultures, systems, and processes. The following challenges can disrupt business continuity:

  • Operational complexity doubling overnight: As structures and processes merge, critical functions such as IT, finance, or customer support can overlap or lack clear ownership, creating gaps and miscommunication.
  • Technology stack overlap: Separate IT ecosystems can be challenging to integrate, leading to access issues, data loss, or outages.
  • Cultural misalignment: Poor communication, shifting processes, and competing priorities can lead to poor decisions that affect critical services.
  • Different risk appetites: Variations in risk tolerance can lead to insufficient controls and contingency planning.
  • Conflicting BCM approaches: One organisation may have a mature, well-tested program, while the other relies on manual processes or outdated plans, compromising recovery time objectives (RTOs).
  • Increased regulatory exposure: Entering new markets or sectors introduces additional compliance requirements and reporting obligations. If not aligned, gaps can lead to fines, delays, or reputational harm.
  • Supply chain blind spots: Merging supplier networks can create duplicate vendors, hidden dependencies, or concentration risks. Without clear insight, one supplier failure can disrupt critical services.

Each of these challenges can disrupt service delivery if not addressed early, as part of a structured plan. As systems merge, teams reorganise, and policies change, small gaps can grow into operational incidents without clear continuity governance.

8 Ways to Maintain Business Continuity and Resilience During an M&A

1. Assess Continuity Capabilities During Due Diligence

A target’s business continuity and resilience program provides insight into its operational stability, exposure to disruption, and ability to recover from incidents. Reviewing these capabilities before the deal closes helps identify integration risks early. During the due diligence phase:

  • Evaluate the target organisation’s business continuity plans.
  • Verify how often teams update and test continuity plans and controls.
  • Review test results, incident history, and past failures.
  • Check if plans are practical and actionable, or merely documented.
  • Confirm if they use a BCM platform or rely on manual processes.
  • Identify gaps in governance, ownership, and oversight.
  • Analyse how previous plan failures were addressed.
  • Evaluate how recovery time objectives (RTOs) and risk appetite compare to yours.
  • Assess the overall maturity of their BCM and resilience program.

Early insight into the target organisation’s risk and resilience profile helps you create mitigation plans and make better decisions. You reduce downtime and avoid inheriting vulnerabilities.

2. Conduct a Combined Business Impact Analysis Early

Once executives sign the deal, involve business continuity subject matter experts (SMEs) from both organisations to perform a joint business impact analysis (BIA).

  • Identify critical services, systems, and regulatory obligations across both companies.
  • Address interdependencies, differing risk appetites, and gaps in recovery capability.
  • Align RTOs and recovery point objectives (RPOs) to ensure they fit within your overall risk appetite.

Involve business continuity SMEs from both organisations during the BIA. Their input uncovers hidden dependencies, ensures temporary controls are in place, and helps align processes and culture for a smooth transition.

3. Map and Rationalise Systems and Technology Platforms

During technology integration in M&A, fragmented systems and siloed data create inefficiencies and increase the risk of security or privacy problems. To address this, take the following steps:

  • Build an inventory of all technology platforms and applications across both organisations.
  • Identify overlapping systems and integration risks across technology platforms, processes, and workflows.
  • Protect mission-critical systems during migration to prevent downtime and customer-facing disruptions.
  • Establish interim safeguards such as parallel systems, rollback plans, or enhanced monitoring during decommissioning or consolidation.

Integration plans must include safeguards and contingency plans to prevent outages and maintain service continuity.

4. Unify Risk Appetite and Governance Structures

Organisations entering an M&A rarely share the same governance model or risk appetite. Successful integration requires executive alignment across business units, risk functions, and operational teams.

  • Align executive teams on shared risk thresholds, escalation protocols, and governance decision rights.
  • Update contact lists to align with your Active Directory to clarify ownership and responsibility.
  • Clarify decision-making authority and escalation routes during incidents and outages.
  • Create combined crisis management teams and incident response protocols.
  • Identify policies and processes that strengthen resilience and those that require enhancement.

By prioritising strong business continuity from the start, you minimise incidents and downtime during integration. Involve resilience and BCM teams to build ownership, find strengths and gaps, and discover commonalities that guide alignment.

5. Evaluate and Consolidate Third-Party Risk

M&A transactions combine not just companies, but also their third-party ecosystems, supply chains, and service providers. Third-party vendors affect continuity and resilience, so review them carefully.

  • Create an inventory of vendors and suppliers across both organisations.
  • Evaluate the resilience maturity of each vendor using questionnaires, audits, certifications, and SLAs.
  • Assess overlapping vendors and identify potential redundancies.
  • Ensure all suppliers meet compliance and security requirements and address gaps in certifications and controls.
  • Map supply chain dependencies to identify single points of failure.

Track the performance of your third parties, conduct assessments, and review compliance regularly during integration. Knowing the shared supply chain helps you spot risks, prevent disruptions, and lower regulatory and operational exposure.

6. Standardise and Centralise BCM Data

Fragmented data poses integration challenges. Spreadsheets, disconnected BCM systems, and siloed reports make it hard to view recovery status and control effectiveness across both organisations.

  • Establish a single source of truth for continuity and incident data during the transition.
  • Evaluate BCM processes and look for opportunities to standardise and align.
  • Review continuity data, dashboards, and reporting processes to pinpoint inconsistencies and gaps.
  • Determine whether to unify both programmes on your existing platform or implement a more capable continuity solution.

Over time, work towards aligning both BCM programmes on a single platform to improve visibility, reduce duplication, and streamline operations. Standardise terminology, risk categories, and reporting structures to lay the groundwork for consistent executive dashboards and board-level oversight.

7. Build a Unified Resilience Culture

Resilience in mergers and acquisitions depends as much on people as on process. Provide clear guidance and training to help employees respond to crises in the new organisation.

  • Communicate changes in continuity procedures proactively throughout the transition.
  • Align terminology, governance, and process workflows, clarifying expectations for incident response, escalation, and reporting across legacy teams.
  • Deploy emergency notification and crisis management tools to ensure employees receive real-time updates.
  • Use global threat intelligence tools to alert staff of emerging cyber and operational risks across the combined entity.

By keeping staff informed using communication and threat-monitoring tools, employees can respond to incidents more quickly, reducing downtime during the transition.

8. Continuously Monitor Integration Risk

Merging two companies unfolds over months or years, with systems, teams, and processes constantly changing. Continuous monitoring of integration risk helps prevent operational disruptions, control gaps, and service interruptions.

  • Establish a dedicated risk register for integration-related issues.
  • Define controls for identified risks.
  • Track incidents, near misses, and ongoing vulnerabilities at all stages of the integration plan.
  • Use incident and risk data from the integration risk register to refine BCM plans and prevent repeated disruptions during the merger.
  • Report BCM status regularly to executive leadership and the board.

By continuously tracking integration risks, you can make timely decisions, strengthen resilience, and assure stakeholders.

Merging BCM Programmes

Over time, work towards consolidating temporary M&A measures into a unified resilience program to avoid gaps and duplication of effort. Decide whether to consolidate both BCM programmes onto an existing platform or select a new BCM tool that supports consistent processes and effective continuity management.

Before the combined resilience program can be set up on a platform, organisations will need to complete these 10 steps:

  1. Identify business-critical processes across both entities
  2. Plan how often BIAs will be conducted and what will be assessed
  3. Build recovery plans with clear steps and ownership
  4. Define a joint risk appetite and set controls to operate within it
  5. Align terminology, risk ratings, and categorisation
  6. Determine how often plans will be updated and checked for validity
  7. Implement robust controls and backups to ensure service continuity even during a crisis
  8. Build a schedule for regular plan testing, tabletop exercises, and simulations to check for gaps
  9. Establish a consistent incident reporting process with clear escalation routes and recovery steps
  10. Decide what metrics you want to present to the board to align reporting outputs

Completing these steps before deploying the new combined program on a platform reinforces operational resilience and ensures compliance. It also supports a smoother implementation of the new program.

Combining Resilience Plans Across the Merged Entities

M&As present an opportunity to advance your resilience program, bring in fresh expertise, and consolidate legacy processes onto a unified BCM platform. With strong executive sponsorship and aligned governance, you can strengthen continuity, close operational gaps, and gain real-time visibility into recovery readiness and incident trends. Establishing a single, consistent program also saves time and reduces duplication.

Business continuity and resilience platforms facilitate integration by centralising your data, automating processes, and aligning teams. They build consistent BCM practices, improve transparency, and accelerate decision-making, helping your combined organisation scale operations while maintaining uninterrupted service.

The Strategic Advantage of Resilience During M&A

Growth through acquisition should strengthen your organisation, not strain it. By integrating business continuity and resilience across the M&A lifecycle, you keep operations stable through ownership changes and integration complexity. This reduces disruption, safeguards revenue and brand reputation, and enables the combined organisation to realise its full strategic potential.

During an M&A, customers expect uninterrupted service, regulators demand compliance, and employees require clarity, while competitors look to exploit weakness. A disciplined approach to continuity supports efficient transformation and minimizes avoidable setbacks.
