The manual performance of data balancing procedures is a slow, tedious, labor-intensive, error-prone process:
Because data balancing tasks are scheduled manually, some tasks may not be performed at the correct time or at all. If quality control balancing is not performed on time, errors go undetected and entire applications may have to be rerun.
Errors can easily be made when manually performing data balancing tasks.
Manual checking of "sensitive" data may require the time of highly paid professionals who are not always available (due to vacation, illness, and so on). Moreover, manual balancing is a clerical task that most professionals would rather not have to do.
The usage of output produced at night or on weekends may be delayed until manual checking can be performed during the next working day.
When erroneous data is found, other persons have to be manually notified to take various corrective actions.
The diagram below illustrates the daily flow of manual quality control of computer processes. For each job, scheduling and processing of data balancing tasks are usually performed for both job input and job output. Without Control-M/Analyzer, all balancing tasks are performed manually. The result is often "too little, too late" and the consequences may be expensive, embarrassing, or both.
