"Before commencing a formal investigation (and especially before starting the evidence collection process), it might be necessary to prepare the subject organisation... such as preparing the managers of the employees who will be involved in the investigation, notifying key decision makers, and notifying the organisation's legal counsel".

"Duplicate testing is used to identify transactions with duplicate values in specified fields ... fields such as cheque numbers, invoice numbers, and government identification numbers ... searching for duplicates within these fields can help the fraud examiner find anomalies that merit further examination".
This directly addresses Tony's need to ensure no two invoices have the same number.

TheFraud Examiners Manualstates:
"If a business or individual constructs a new building or makes improvements to an existing building, there should be a building permit on file with the local building authority. In many cases, the person applying for permits will be the owner or someone traceable to the owner." CFE Prepsupports this:
"Building permit records... are often required before most businesses can open... and often list the owner or someone traceable to the owner." Thus,building permit recordsare most likely to help identify the restaurant's owner.

The manual defines:
"Open questions are those worded in a way that makes it difficult for the respondent to answer 'yes' or 'no.' The typical open question calls for a monologue response and can be answered in several different ways." Example given: "Please tell me about your job." Allison's question ("Why did you choose to do business with that vendor?") invites explanation, not a yes/no response - making it an open question.

Predictive analytics is defined as:
"the use of historical data combined with statistical, analytical, and machine learning techniques to create models that capture trends and produce forecasts".
So, optionCbest describes predictive analytics.
