Diabetes is a relatively common condition in which the human pancreas is unable to produce sufficient quantities of a hormone called insulin. Clearly, this depends on the people involved and the nature of the disagreement.

I therefore choose an appropriate enyenharia when discussing con- cepts such as safety and dependability, system modeling, reuse, etc. The con- ventional treatment of diabetes involves regular injections of genetically engineered insulin. The system types that Sommervolle use as case studies are: The key requirements of such systems are reliability, even in hostile environ- mental conditions, and maintainability. The potential for damage, the extent softwrae the damage, and the people affected by the damage should influence the decision.

The example of a data collection system that I use is a wilderness weather station. Enviado por Barbara flag Denunciar. Another ethical issue is participation in the development of military and nuclear systems. I introduce each of these systems in this chapter; more information about each of them is available on the website software-engineering-book.

Although the system may not have been validated according to predefined criteria, these criteria may be too strict. You must make up your own mind in these matters. The system may actually operate safely throughout its life- time. The appropriate ethical posi- tion here depends on the views of the people involved. If you discuss these while they are just a suspicion, you may be overreact- ing to a situation; if you leave it too long, it may be impossible to resolve the difficulties.

An embedded system This is a system where the software controls some hard- ware device and is embedded in that device. A difficult situation for professional engineers arises when their employer acts in an unethical way. This is the approach taken by Laudon Laudon and Johnson Johnson If the situation is very dangerous, it may be justified to publicize it using the national press or social media.

I find that a philosophical approach is too abstract and difficult to relate to every- day experience so I prefer the more concrete approach embodied in professional codes of conduct Bott ; Duquenoy People who suffer from diabetes use the system. The software controlling this system is an embedded system that collects information from a sensor and controls a pump that delivers a controlled dose of insulin to a user.

More recent texts such as that by Tavani Tavani introduce the notion of cyberethics and cover educao the philosophical background and practical and legal issues. However, you should always try to resolve the situation while respecting the rights of your employer. Issues in embedded systems typi- cally include physical size, responsiveness, and power management, etc.

They include ethical issues for technology users as well as developers.

A sensor-based data collection system This is a system whose primary purposes are to collect data from a set of sensors and to process that data in some way. An information system The primary purpose of this type of system is to manage and provide access to a database of information.

Issues in information systems include security, usability, privacy, and maintaining data integrity. Equally, if an employee is taken on and makes clear that he or she does not wish engenhraia work on such systems, employers ds not exert pressure to do so at some later date.

The dommerville of an embedded system that I use is a software system to control an insulin pump for people who have diabetes. Where they cannot be resolved, the engineer is faced with, perhaps, another problem. Some people feel strongly about these issues and do not wish to participate in any systems development associated with defense systems.

For example, if you disagree, in principle, with the policies of more senior management in the company, how should you react?

In this situation, it is important that both employers and employees should make their views known to each other in advance.

We all face such ethical dilemmas in our professional lives, and, fortunately, in most cases they are either relatively minor or can be resolved without too much dif- ficulty. Where an organization is involved in military or nuclear work, it should be able to specify that employees must be willing to accept any work assignment. The principled action may be to resign from their job, but this may well affect others such as their partner or their children.


It is also the case that, even when properly validated, the system may fail and cause an accident.

Programming environments, such as Eclipse Vogel will be the most familiar type of environment for readers of this book. Others will work on mili- tary systems but not on weapons systems.

I think that ethics are engenhaia discussed in a software engineering context and not as a subject in its own right. It can be considered from a philosophical standpoint where the basic principles of ethics are considered and software engineering ethics are discussed with reference to these basic principles.

Insulin metabolizes engenharua sugar in the eicao. Therefore, I do not discuss software engineering ethics in an abstract way but include examples in the exercises that can be the starting point for a group discussion. Engenharia de Software 3. Say a company is responsible for developing a safety-critical system and, because of time pressure, falsifies the safety validation records. In any situation where different people have different views and objectives, you are likely to be faced with ethical dilemmas.

If you feel that there are problems with a software project, when do you reveal these problems to management? Is it best to argue a case for your position from within the organization or to resign engnharia principle?

The example of an information system used is a medical records system.
