A method and associated system. Expected problems in a workload plan are predicted in response to any current occurrences of impacting system events according to the workload plan and corresponding expected impacts of the impacting system events of system events on execution of impacted work units of work units. Predicting the expected problems includes: identifying workload deadlines relating to the impacted work units in the workload plan; estimating intervention times for addressing the expected problems before missing the corresponding workload deadlines; determining corresponding minimum times required to fulfill the workload deadlines according to a progress of the workload plan; and estimating each of the intervention times further according to the minimum time of the corresponding workload deadline. An intervention program of system interventions on the computing system is established. The system interventions address the current occurrences of impacting system events according to the corresponding expected problems.
