Crazy Al’s Used Cars has decided to implement a new system to keep track of the cars which he purchases, repairs and sells. Crazy Al has been convinced by his cousin Eddie (who didn’t do computing at Monash University), that he shouldn’t use this new-fangled OO to build the system, but that he should use Structured methods to do so. The new system has the following requirements:

The system must record the purchase of cars from customers and other dealers. The primary information stored on a purchase is make, model, registration number and price paid.
 Each car purchased by Crazy Al’s is sent to a car mechanic to be serviced and repaired if necessary. The system must record the transfer of a car to a car mechanic and also record the cost of the service and any repairs when the car returns.
 The system should record any sales by Crazy Al’s to a customer.

Every sale is made by a specific salesperson and should be recorded as belonging to that salesperson.

The system should have a search function that allows a salesperson to look through the current cars and see if they have any stock that matches the needs of a client.

Each week, the system should output a report of all purchases and all sales made by Crazy
Al’s to be given to management.

Each week, the system must calculate the tax to be paid to the taxation department. The tax payable on each sale should be stored in the system.

You are the managing director of a small software development firm called TechnoWizards which currently employs eight software developers. You have only been in business for the last five years, since setting out on your own as a contractor, but you have been very successful in your business. The systems that you build are for the financial sector. The contracts you receive are fixed price and thus the price cannot be changed after the quote has been given.
Your current software process is not clearly defined, though you do have defined standards for testing and coding. Due to your past experience in the finance sector, you have done all the analysis and most of the design for the company.
You have now been offered the contract to build a major new system for a finance company.
This system will be at least three times the size of anything you have built to date and will require you to take on at least 15 more developers. Your current staff is highly competent, but you have never had to deal with more than four developers working on any one project before.
You are familiar with the technology that will need to be used in the new system, but you are aware that the finance company is not and is also uncertain about the requirements of the system. You realise that you will not be able to handle the analysis and design for the project by yourself and will be restricted to a review role in this area.
(a) Describe, in some detail, the three most likely risks that may cause the project to fail.
(9 marks)
(b) For each of the risks identified in part (a), suggest what action could be taken to reduce that risk. (6 marks)
One part of the contract conditions is that, it is specified that TechnoWizards achieve AS3563 quality certification within 12 months of commencing the project. In the past you have avoided such things as unnecessary bureaucracy, however given the commercial benefit of the contract, it seems that it is inevitable.
(c) Describe, in some detail, how you would ensure that TechnoWizards would gain some benefit from the adoption of AS3563. (5 marks)
You recently attended a demonstration of a leading CASE tool and were impressed by the capabilities that it showed and its potential for improving the software process in
TechnoWizards. However, given the high cost and the potential for failure in introducing
CASE, you feel the need to do some research about the problem.

National Chemical Wholesalers (NCW) is a long-established firm that sells large quantities of bulk chemicals to manufacturers. In the 1960s, NCW created an IBM mainframe COBOL system to handle its sales system. Since that time, the company has extended and developed that initial system significantly. The software development group has become expert in
COBOL and IBM mainframes.
In the last five years however, the archaic nature of the system has been causing more and more problems and is beginning to have a serious impact on the sales of the company. The
Sales department is insisting that they need a system that will provide up to date and on-line information to their sales representatives while they are in the field. This will require a system that can contact the mainframe via a mobile telephone modem on a notebook computer. They also want to see the new sales system using a Graphic User Interface, instead of the standard text interface that the company uses.
Initial requirements analysis indicates that the system will be approximately the same size as the systems that are currently being built by the software development group. It is also clear that the Sales department is unclear about the required functionality of the system and that the proposed budget for the new system is underfunded by approximately 20%.
List five (5) risks which may cause the project to fail, estimate the severity and probability of the risk and what action you could take to reduce that risk occuring.

EntraNet Solutions is a software development house that specialises in building small distributed systems for other companies. An example of a system they have built is the one they built for a firm of lawyers. Sharkey and Botherton is a law firm that maintains offices in
Melbourne, Sydney, Brisbane and Canberra. EntraNet Solutions built them an integrated system that continually communicates between the four offices and allows an employee of the firm to keep up to date with the latest changes in any case. EntraNet Solutions has become highly competent at producing these small, distributed systems.
EntraNet is now considering tendering for a much larger system, an educational system to be used by Victorian schools to handle educational matters. This system will link over one thousand schools across Victoria in an on-line, interactive system with real-time updating of the data. The actual technology to be used is very similar to that used by the company in previous developments, though the scale of the project is far greater. Other issues that may be of relevance to the decision to tender for the contract are
Page 11 of 25

CSC3080 semester 1 1998 Deferred Exam

One of the three owners of the organisation is against doing business with the Government as he thinks there is too much red tape.

EntraNet will have to increase their staff from 15 people to 30 people to handle the new project.

EntraNet will also have to hire contractors to assist in the project, something that they have not done to this stage.

Initial discussions with the Department of Education management who is commissioning the system indicate there is a lot of controversy amongst the senior managers as to what they actually want the system to do.

The management of the company has also decided to introduce a formal system development methodology and sees this project as a good test of the methodology given the significant size increase of the project over previous ones.

Apparently there is also some resistance to the system from the school community to a centralised system.

Discussions with the Department of Education IT section who EntraNet will have to work closely with has revealed a very low level of morale in that group.

Symphony Software has been established for the last 15 years and writes software for the music composing market. They have specialised in developing software for the Macintosh over this time. They have a stable development environment where they have good configuration management, capable project management and clearly understand the requirements of their domain. Apart from measurements of effort exerted, they keep no metrics and their actual development methods are fairly primitive apart from configuration management.
Symphony Software has now decided to start developing a Windows NT version of their software and feel that they will need to have a stronger software development process. They are keen to use Source Lines Of Code (SLOC) metrics to help them estimate how long they will take to build the NT version, given that they have a huge base of old projects that they can use to estimate their productivity. They are also considering adopting a formal quality standard, but as their clients do not require it of them, they are doubtful about its usefulness to the company. d) Symphony Software proposes to implement Source Lines of Code metrics using the
COCOMO methodology. What are the advantages and disadvantages for Symphony
Software in using this type of metric? (5 marks) e) In terms of the Capability Maturity Model, at what level is Symphony Software?
