More recent texts such as that by Tavani Tavani introduce the notion of cyberethics and cover both the philosophical background and practical and legal issues.

Yet others iann that national security is an overriding principle and have no ethical objections to working on weapons edivao. Programming environments, such as Eclipse Vogel will be the most familiar type of environment for readers of this book. They include ethical issues for technology users as well as developers.

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.

Others will work on mili- tary systems but not on weapons systems. In this situation, it is important that both employers and employees should make their views known to each other in advance. It is also the case that, even when properly validated, the system may fail and cause an accident. Say a company is responsible for developing a safety-critical system and, because of time pressure, falsifies the safety validation records.

If you feel that there are problems with a software project, when do you reveal these problems to management? 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.

An information system The primary purpose of softwrae type of system is to manage and provide access to a database of information.

Issues in embedded systems typi- cally include physical size, responsiveness, and power management, etc. A difficult situation for professional engineers arises when their employer acts in an unethical way. Engenharia de Software 3. Although the system may not have been validated according to predefined criteria, these criteria may be too strict.

The example of an embedded system that I use is a software system to control an insulin pump for people who have diabetes. I therefore choose an softward example when discussing con- cepts such as safety and dependability, system modeling, reuse, etc.

Some people feel strongly about these issues and do not wish to participate in any systems development associated with defense systems. Diabetes is a relatively common condition in which the human pancreas is unable to produce sufficient quantities of a hormone called insulin.

The example of a data collection system that I use is a wilderness weather station. In any situation where different people have different views and objectives, you are likely to be faced with ethical dilemmas.

Insulin metabolizes glucose sugar in the blood. 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.

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.

The system may actually operate safely throughout its life- time. An embedded system This is a system where the software controls some hard- ware device and is embedded in that device. 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 engenhaaria user.

The con- ventional treatment of diabetes involves regular injections of genetically engineered insulin. Enviado por Barbara flag Denunciar. You must make up your own mind in these matters. The example of an information system used is a medical records system. 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. People who suffer from diabetes use the system.

I introduce each of these systems in this chapter; more information about each of them is available on the website software-engineering-book.

Sommerviple ethical issue is participation in the development of military and nuclear systems. Clearly, this depends on the people involved and the nature of the disagreement.

The principled action may be to resign from their job, but this may well affect others such as their partner or their children. The general area of ethics and deicao responsibility is increasingly important as software-intensive systems pervade every aspect of work and everyday life. For example, if you disagree, in principle, sommercille the policies of more senior management in the company, how should you react? This is the approach taken by Laudon Laudon and Johnson Johnson Equally, if an employee is taken on and makes clear that he or she does not wish to work on such systems, xommerville should not exert pressure to do so at some later date.

Issues in information systems include security, usability, privacy, and maintaining data integrity. Is it best to argue a case for your position from within the organization or to sommerille in principle? I think that ethics are best discussed in a software engineering context and not as a subject in its own right. The key requirements of such systems are reliability, even in hostile environ- mental conditions, and maintainability.

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.

The system types that I use as case studies are: Where they cannot be resolved, the engineer is faced with, perhaps, another problem. If the situation is very dangerous, it may be justified to publicize it using the national press or social media. Early disclosure of problems may result in damage to the employer and other employees; failure to disclose problems may result in damage to others. The appropriate ethical posi- tion here depends on the views of the people involved. 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 This is an integrated collection of software tools that are used to support some kind of activity.

The potential for damage, the extent of the damage, and the people affected by the damage should influence the decision.
