Preamble
Dr Vivien “Viv” Aldi was extremely impressed with our computing firm’s
–Valkyries
Technologies –
development of theFour Seasons Music’s Database Management System (DBMS) utilising Microsoft Access
2007/2010/2013 (Assignment 1). The business has contracted our firm to assist
in setting up more ofthe business’s various
computer-based information systems.
The next computer-based information system that
the business is interested in is a Decision Support System (DSS) utilising
Microsoft Excel 2007/2010/2013. The DSS will be used to analyse sales trends
for the business to determine future courses of action for the business.
Dr Vivien “Viv” Aldi would like the information
in the Database Management System (DBMS) (Assignment 1) imported into Microsoft
Excel 2007/2010/2013 so that the information can be summarised as a report and
some future analysis of sales trends performed. The suppliers used by the
business, source items from either Austria (AT) orSaint Lucia(LC).
They allow the business to select from either of these two regions on an
ad hoc basic depending on the most favourable exchange rate at the time.
Dr Vivien “Viv” Aldi has noted that a number of
the business’s competitors are providing a discount to customers who place
large orders. The business would like to see what affect adopting a similar
policy would have on the business. The business has also noted a growing number
of online businesses are starting to provide free freight delivery as a way of
encouraging more online business; The business would like to run a number of
scenarios based on potential Mark-up and Freight options to ascertain the best
combination for the business if they were to adopt this policy too.
All phases in this project must be developed with professionalism
and user-friendliness in mind.

Task 11: Report Worksheet
Cost Price (AU) Nested IF
On theReportworksheet:
1.
Develop an IF
function using the newRecommendedExchange Rate Type value (from the DataInput worksheet to calculate
the Cost Price (AU) (in the Cost Price (AU) column) using the following
criteria:
·
If the Exchange Rate Type isAT then the Cost Price
(AU) is calculated by multiplying the Cost Price (AT) by the Exchange Rate (AT
to AU) cell on theDataInput worksheet.
Hint:
Cost Price (AT) x Exchange Rate (AT to AU)
·
If the Exchange Rate Type isLC then the Cost Price
(AU) is calculated by multiplying the Cost Price (LC) by the Exchange Rate (LC
to AU) cell on theDataInput worksheet.
Hint:
Cost Price (LC) x Exchange Rate (LC to AU)
Do not post formulas to the StudyDesk
Forums; it may result in academic misconduct.
2.
Ensure that you includerounding
(to
2 decimal places – Beskeen Excel Unit B) into each calculation in your IF
function anderror checking(Beskeen Excel Unit
E) to avoid incorrect results due to typing mistakes.
Note:All formulas must be designed to be
typed once at the top of each column and copied down to the remaining cells in
the column – Beskeen Excel Unit B.
Also do not include
any unit measures such as $, kg or km in the IF function as this will result in
a #VALUE error message. Brackets must
only be used as indicated in the hints given above, any incorrect or extraneous
usage of brackets may result in loss of marks.
You must remove any reference to the
prefix Report! from these Nested IF functions to reduce complexity and
redundancy of code.
See the
Beskeen Excel Unit E and the Videos provided in the Course Content section for
more details on creating IF functions
3.
Test the IF
function: Once you have completed the Cost Price (AU) IF function, perform
the following two tests on it to ensure that it is working correctly:
·
On theDataInput worksheet, typeLC into the Exchange Rate Type cell.
·
Go to theReport worksheet and
observe whether the Cost Price (AU) have changed.
·
On theDataInput worksheet, typeGIGO into the Exchange Rate Type cell.
·
Go to theReport worksheet and
observe whether the Cost Price (AU) now displays an error message.
Task 12: Report Worksheet
Selling Price Nested IF
On theReportworksheet:
1.
Develop an IF
function using the newRecommendedMarkUp Type value (from the DataInput worksheet) to calculate the Selling
Price (in the Selling Price column) using the following criteria:
·
If the MarkUp Type isStore then the Selling Price is
calculated by increasing Cost Price by the Store’s Recommended MarkUp % from
theDataInput worksheet
Hint:
Cost Price (AU) + Cost Price (AU) x Store
Recommended MarkUp
·
If the MarkUp Type isSupplier then the Selling Price is
calculated by increasing Cost Price by the Supplier’s Recommended MarkUp
Hint:
Cost Price (AU) + Cost
Price (AU) x Supplier Recommended MarkUp
Do not post formulas to the StudyDesk Forums; it
may result in academic misconduct.
2.
Ensure that you includerounding(to 2 decimal places – Beskeen
Excel Unit B) into each calculation in your IF function anderror
checking(Beskeen Excel Unit E) to avoid
incorrect results due to typing mistakes.
Note:All formulas must be
designed to be typed once at the top of each column and copied down to the
remaining cells in the column – Beskeen Excel Unit B.
Also do not include any unit
measures such as $, kg or km in the IF function as this will result in a #VALUE
error message. Brackets must
only be used as indicated in the hints given above, any incorrect or extraneous
usage of brackets may result in loss of marks.
You must remove any reference to the prefix Report! from these
Nested IF functions to reduce complexity and redundancy of code.
See the Beskeen Excel Unit E and the Videos provided in the Course
Content section for more details on creating IF functions
3.
Test the IF
function: Once you have
completed the Selling Price IF function, perform the following two tests on it
to ensure that it is working correctly:
·
On theDataInput worksheet, typeSupplier into the MarkUp Type cell.
·
Go to theReport worksheet and
observe whether the Selling Prices have changed.
·
On theDataInput worksheet, typeGIGO into the MarkUp Type cell.
·
Go to theReport worksheet and
observe whether the Selling Prices now displays an error message.
Task 13: Report Worksheet
Freight Cost Nested IF
1.
On theDataInput worksheet, typeStradivari Freightinto the cell containing the phrase: [Insert
Freight Type here].
2.
On theReportworksheet develop an IF
function using the newRecommendedFreight Type value (from the DataInput worksheet to calculate the Freight Cost
(in the Freight Cost column) using the following criteria:
·
If the Freight Type isStradivari Freight then the Freight Cost is calculated a quarter of a cent ($0.0025)
per kilometre (Distance) and three dollars seventy-five cents ($3.75) per
kilogram of the item’s freight weight per item ordered (Order Qty).
Hint:
($0.0025 x Distance + $3.75 x Item Weight) x
OrderQty
·
If the Freight Type is Guarneri Transportthen the Freight Cost
