Systems and arrangements for pre-processing data to detect and analyze system, application, or the like, incidents to identify incidents likely to cause a significant business impact are provided. Historical data related to incidents that previously occurred may be analyzed to quantify an impact of each incident. The quantified impact may be compared to a threshold and, if the impact above the threshold, the incident may be flagged as having a significant business impact. If the impact is below the threshold, the incident may be flagged as not having a significant business impact. Upon detecting an incident, data from the incident may be compared to the historical data of incidents having a significant business impact. If aspects of the incident are similar to one or more incidents having a significant business impact, the system may determine that the newly received incident is also likely to cause a significant business impact.
