system testing is to test the system until the testing budget is exhausted and then deliver the system to customers

 COM 3019 – SOFTWARE ENGINEERING

1

ASSIGNMENT 3

1. (a) A common approach to system testing is to test the system until the testing budget is

exhausted and then deliver the system to customers. Discuss the ethics of this approach

for systems that are delivered to external customers. (12mks)

(b) Some people argue that developers should not be involved in testing their own code

but that all testing should be the responsibility of a separate team. Give arguments for and

against testing by the developers themselves. (10mks)

(c) Explain why testing can only detect the presence of errors, not their absence. (10mks)

2. (a) Explain why you normally use several architectural patterns when designing the

architecture of a large system. Apart from the information about patterns that I have

discussed in this chapter, what additional information might be useful when designing

large systems? (8mks)

(b) Suggest architecture for a system (such as iTunes) that is used to sell and distribute

music on the Internet. What architectural patterns are the bases for this architecture?

(8mks)

(c) Using the UML graphical notation for object classes, design the following object

classes, identifying attributes and operations. Use your own experience to decide on the

attributes and operations that should be associated with these objects.

i. Telephone (5mks)

ii. A printer for a personal computer (5mks)

iii. A personal stereo system (5mks)

COM 3019 – SOFTWARE ENGINEERING

iv. A bank account (5mks)

v. A library catalogue (5mks)

3. (a) A small company has developed a specialized product that it configures specially for

each customer. New customers usually have specific requirements to be incorporated into

their system, and they pay for these to be developed. The company has an opportunity to

bid for a new contract, which would more than double its customer base. The new

customer also wishes to have some involvement in the configuration of the system.

Explain why, in these circumstances, it might be a good idea for the company owning the

software to make it open source. (10mks)

(b) Identify possible objects in the following systems and develop an object-oriented

design for them. You may make any reasonable assumptions about the systems when

deriving the design:

i. A group diary and time management system is intended to support the timetabling

of meetings and appointments across a group of co-workers. When an

appointment is to be made that involves a number of people, the system finds a

common slot in each of their diaries and arranges the appointment for that time. If

no common slots are available, it interacts with the user to rearrange his or her

personal diary to make room for the appointment. (5mks)

ii. A filling station (gas station) is to be set up for fully automated operation. Drivers

swipe their credit card through a reader connected to the pump; the card is

verified by communication with a credit company computer, and a fuel limit is

established. The driver may then take the fuel required. When fuel delivery is

complete and the pump hose is returned to its holster, the driver’s credit card

account is debited with the cost of the fuel taken. The credit card is returned after

debiting. If the card is invalid, the pump returns it before fuel is dispensed. (5mks)

(c) Some people argue that developers should not be involved in testing their own code

but that all testing should be the responsibility of a separate team. Give arguments for and

against testing by the developers themselves. (7mks)

Green Pastures Static Budget Income Statement

Assignment Content
Purpose of Assignment
This comprehensive case requires students to evaluate a static budget and prepare flexible budgets to meet managerial needs. Students are required to calculate and analyze variances and discuss how variances are critical to managerial decision making.

Resources
Green Pastures Static Budget Income Statement
Generally Accepted Accounting Principles (GAAP), U.S. Securities and Exchange Committee (SEC)
Tutorial help on Excel® and Word functions can be found on the Microsoft Office website. There are also additional tutorials via the web offering support for Office products.

Assignment Steps
Scenario: Green Pastures is a 400-acre farm on the outskirts of the Kentucky Bluegrass, specializing in the boarding of broodmares and their foals. A recent economic downturn in the thoroughbred industry has led to a decline in breeding activities, and it has made the boarding business extremely competitive. To meet the competition, Green Pastures planned in 2017 to entertain clients, advertise more extensively, and absorb expenses formerly paid by clients such as veterinary and blacksmith fees.

The budget report for 2017 is presented as an attachment. As shown, the static income statement budget for the year is based on an expected 21,900 boarding days at $25 per mare. The variable expenses per mare per day were budgeted: feed $5, veterinary fees $3, blacksmith fees $0.25, and supplies $0.55. All other budgeted expenses were either semifixed or fixed.

During the year, management decided not to replace a worker who quit in March, but it did issue a new advertising brochure and did more entertaining of clients.

Develop a 700-to 1050-word examination of the financial statements and include the following based on the static budget report:
What was the primary cause(s) of the loss in net income?
Did management do a good, average, or poor job of controlling expenses?
Were management’s decisions to stay competitive sound?
Prepare a flexible budget report for the year.
Based on the flexible budget report:
What was the primary cause(s) of the loss in net income?
Did management do a good, average, or poor job of controlling expenses?
Were management’s decisions to stay competitive sound?
What course of action do you recommend for the management of Green Pastures?

The primary cause(s) of the loss in net income

            Looking at the static budget report, it was evident that Green Pastures’ net income dropped as a result of a declined in the number of boarding days as well as the boarding fee. Analysis showed that boarding days declined by about 13 % from 21,900 to 19,000 which is a decrease of 2,900 boarding days as shown in the computation below.

            The boarding fees also declined by 20 % from $25.00 daily to $20.00 daily as shown in the computation below.

The overall reduction in sale revenue was $167,500 which is about 31 %. The computation of percentage is shown below.

The overall computations of boarding fees on a daily basis of during the two economies (healthy and downturn) are presented below.

Whether the management did a good, average, or poor job of controlling expenses?

            Based on the outcome of the computation, one can conclude that the management did a poor job in managing variable expenses. A decline of approximately 13 % of boarding days should have led to reduction of variable expenses with a similar margin. The computation showed that variable expenses only declined by about half of the margin that was expected to decline as shown below.

This is a clear indication that the management did a shoddy job of controlling variable expenses. However, they did a good job in controlling fixed expenses because they were under budget by $4,000 despite the additional expenses that were incurred in entertainment and advertising.

Whether the management’s decisions to stay competitive were sound?            The decision taken by the management to stay competitive were sound because as they reduced the boarding days, they took a bold decision………………………………………………………………………………………………

The states currently have a law in place requiring them to maintain a balanced budget

The states currently have a law in place requiring them to maintain a balanced budget. Do you believe this should be required of the federal government as well? Why, or why not? What might be the ramifications if this philosophy drove the federal budget?
