Application Controls
Application controls are automated or manual procedures within a specific application designed to ensure the completeness, accuracy, and validity of data processing.
Explanation
Application controls operate at three stages: input controls (edit checks, validation rules, sequence checks), processing controls (batch totals, run-to-run totals, reasonableness tests), and output controls (reconciliations, distribution controls, report reviews). Input controls are the most critical because preventing errors at entry is more efficient than detecting them later. Common input controls include field checks, range checks, check digits, and limit tests.
Key Points
- •Three categories: input, processing, and output controls
- •Input controls are most critical — prevent errors at the point of entry
- •Examples: edit checks, batch totals, hash totals, check digits
Exam Tip
Know the specific types of input validation controls — check digits detect transposition errors, hash totals verify completeness, and limit tests catch outliers.
