Stand-alone vs. ERP systems

Explain why controls over sales information may be even more important in an ERP environment than in an environment where a stand-alone sales system is deployed. Indicate for which type of controls (preventive, detective, corrective) this statement is particularly true.

Explain the role of DURABILITY of data in a database management system for management's period end assertion 'COMPLETENESS'. In your answer, refer to the related information quality goal and draw on an example from the expenditure to illustrate how a break-down of the ACID property affect the assertion.

Assume total errors amounting to AUD 10,000 (absolute value!) in the Sales Revenue account of an organisation have been detected. Further assume that this amount is the result of 200 individual errors - all either systematic errors or random errors.

Would the average value of each individual error be likely higher, lower, or unaffected (i.e., equal) if all errors were systematic errors as compared to random errors? Explain

Academic research by Wiedemann & Wiegmann (2018, 104) quotes a head of global product management as saying:

"Well, everybody has the same numbers, but then the real work starts in interpreting them, doing variance analysis, making follow up calls and reviewing closely why specific effects exist. You need somebody who is able to explain in an hour precisely the drivers and influences that affected the business in each region, in each strategic entity in the last two months, and to derive implications in order to steer [the organisational entity you are responsible for] effectively in the upcoming months".

What conclusions can you draw from this quote with respect to the head of global product management's 'view' of the firm and the 'type' of information system used by the company. Explain why you came to this conclusion.
