Government systems often relate to the payment of benefits, grants, assistance, etc. to individuals and to organizations. The tests with IDEA tend to be specific to the particular system (which is often unique) but there are some general categories of tests:
Analyses
Analyze sales and profitability by area, salesperson, month, store, category, vendor or all
Summarize receipts by type
Summarize cash receipts by the account code distribution for reconciliation to general ledger postings
Summarize shipments by warehouse for product distribution analyses
Produce analytical review information on sales by value band
Analyze product demand by summarising products by due date
Analyze open orders and open invoices by customer for credit control
Reconcile booked items to inventory reserved (on hold) items
Calculations
Reproduce sales summaries, posting totals
Test pricing, discount calculations on invoices
Control profits by calculating line item margins before shipment
Analyze variances in sales and summarize trends numerically or graphically
Report on the correlation between items shipped and items ordered
Isolate detail and average backlog by customer, item, location, etc.
Exception Tests
Identify sales values higher than usual for item type
Identify sales prices less than expected for product type or large discounts given
Identify large credit notes
Identify high-volume amounts by products, customers, sales representative, store, etc.
Extract all sales data for audit by customer, product, region, etc.
Gaps and Duplicates
Missing sales invoice numbers
Missing dispatch note numbers
Duplicate invoices (either duplicate invoice number, dispatch number, or customer and detail/ amount)
Matching and Comparing
Match the benefits file to the employees' payroll file using the address, postal code, or bank account details
Cross-match the benefit beneficiary name with names on other benefit systems, the electoral system,or central register
Cross-match addresses with property registers (where available) to ensure a valid address has been given
Cross-match bank account details/addresses with employee payroll information
Warning: There may be certain legal considerations in different countries on whether crossmatching between systems is allowed. Experience indicates that the incidence of error or fraud is often higher in certain groups or categories of people. Tests with IDEA in these areas are often very effective, but again care must be taken not to infringe on any laws or regulations, particularly in relation to minority groups.
