Problem management is the best way to enable the organization to resolve the issue of repeated failures of critical data processing services, as it focuses on identifying and eliminating the root causes of incidents and preventing their recurrence. Problem management involves analyzing incidents, performing root cause analysis, finding solutions, implementing changes and documenting lessons learned. Incident management is not the best way to resolve the issue, as it focuses on restoring normal service operation as quickly as possible after an incident occurs, but does not address the underlying causes or prevent future incidents. Service level management is not the best way to resolve the issue, as it focuses on defining, monitoring and reporting on the service levels agreed upon between service providers and customers, but does not address the causes or solutions of incidents. Change management is not the best way to resolve the issue, as it focuses on ensuring that changes are implemented in a controlled and coordinated manner, but does not address the identification or elimination of incidents. References:
