1. A method for determining capacity in complex systems by setting capacity values for service transaction types that assist in identifying performance bottlenecks comprising:

  • listing the service transaction types;

    identifying Workflow Manager (WFM) data where invocation data records for each of the service transaction types are located;

    retrieving the WFM data;

    parsing the WFM data to acquire the invocation data records for each of the service transaction types;

    for a given transaction type;

    determining average response time RTh aggregation levels and volume counts counth, wherein the volume counts counth is the traffic load and is a count of successful transactions within a predetermined measurement interval h and the average response time RTh is calculated for successful transactions within the predetermined measurement interval h;

    performing a linear regression of data pairs (counth, RTh);

    determining a Response Time Model RTM (x) to be
