Beyond go-live: Leading through post-implementation risks

For many organizations, a system go-live is seen as the final milestone in a long and often complex technology transformation. In reality, it marks the beginning of a far more critical phase — when operational stability is tested, user adoption is realized, and risks begin to surface.  Organizations that excel post-go-live are those that plan not just for deployment, but for the discipline of sustaining, securing, and optimizing their new environment.  

To protect the value of your investment and to prepare for the scrutiny of being compliant, a comprehensive post-implementation strategy is not optional—it is essential.  To maximize the value of a new system and reduce post-go-live risks, organizations should go beyond technical deployment and concentrate on the following key areas:

‍

Compliance verification

A common misconception is that regulatory compliance and security controls are fully addressed before go-live. In practice, many controls can only be validated once the system is operational.  For instance, under SOX, any system replacing a previously in-scope application is likely to be included in the current audit cycle.  Although it would be a leading practice that test scripts include the testing of all controls, actual compliance and controls are reliant on configuration and functionality post-go-live. To reduce the risk of surprise control deficiencies, organizations must proactively engage with external auditors.  Internal Audit, or an experienced advisory partner, can act as a strategic facilitator between business process owners, IT, and external auditors to help identify gaps early and prioritize remediation—without derailing the post-go-live hyper-care process.  

‍

Change management requirements

Any changes to the newly live system—whether related to functionality, configuration, security, integrations, reporting, customizations, or upgrades—must follow the organization’s formal change management policy.  It is required that all modifications are documented, reviewed, tested, and approved.  However, during the hyper-care phase, developers may need elevated or emergency access to production to troubleshoot urgent issues. While sometimes necessary, this introduces risks such as unauthorized changes, SOD conflicts, and policy deviations.  A well-defined strategy that balances operational urgency with policy compliance is critical. Temporary access controls, enhanced monitoring, and fast-tracked approvals are potential solutions to maintain change discipline without impeding the support effort.

‍

User access validation

End users, administrators, and even third-party implementation partners may require elevated access post go-live.  Without timely oversight, this temporary access assignments may linger—creating persistent or even unnoticed SOD violations, elevating fraud, error, and compliance risks.  A focused access review post-implementation is essential to validate roles, remove excess privileges, support least-privilege principles and test alignment with control design.    

‍

Data integrity and system interfaces

Successful implementation is more than just functionality— the trust in data is also critical. If reports are inaccurate, interfaces fail to transfer complete and accurate data between systems or data converted contains errors, management is at risk of making flawed decisions.  Testing end-to-end data flows for completeness, accuracy, and appropriate reconciliation and performing data validation post-go-live increases confidence in management, internal and external compliance teams and auditors.  

‍

Process documentation refresh

When control documentation references legacy processes or system functionality no longer in use, it may lead to ineffective testing or control deficiencies.  Outdated or inaccurate policies, process documentation, and control narratives also complicates training, support, and issue resolution, increasing long-term costs and risk.  By validating documentation post-go-live, organizations not only strengthen their control environment but also create a sustainable foundation for audit readiness, process optimization, and knowledge transfer.  

‍

System go-live may feel like the finish line, but true success is measured in the weeks and months that follow. Post-implementation is the phase where technology meets governance. It is when the system must prove that it not only works, but is secure, reliable, compliant, auditable and primed for long-term value. Applying a comprehensive post-go-live risk approach with the right controls during this critical period protects business integrity, enables audit readiness, and facilitates sustainable user adoption.
