Say a company is responsible for developing a safety-critical system and, because of time pressure, falsifies the safety validation records. The system may actually operate safely throughout its life- time. For edciao, if you disagree, in principle, with the policies of more senior management in the company, how should you react?

Where they cannot be resolved, the engineer is faced with, perhaps, another problem. In this situation, it is important that both employers and employees should make their views known to each other in advance. Yet others feel that national security is an overriding principle and have no ethical objections to working on weapons systems. Another ethical issue is participation in the development of military and nuclear systems.

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 A difficult situation for professional engineers arises when their employer acts in an unethical way. 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.

Issues in embedded systems typi- cally include physical size, responsiveness, and power management, etc. However, you should always try to resolve the situation while respecting the rights of your employer. An information system The primary purpose of this type of system is to manage and provide access to a database of information.


The example of an embedded system that I use is a software system to control an insulin pump for people who have diabetes. Insulin metabolizes glucose sugar in the blood. The general area of ethics and professional responsibility is increasingly important as software-intensive systems pervade every aspect of work and everyday life.

The principled action may be to resign from their job, but this may well affect others such as their partner or their children. The con- ventional treatment of diabetes involves regular injections of genetically engineered insulin.

Early disclosure of problems may result in damage to the employer and other employees; failure to disclose problems may result in damage to others. People who suffer from diabetes use the system. 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.

Programming environments, such as Eclipse Vogel will be the most familiar type of environment for readers of this book. If the situation is very dangerous, it may be justified to publicize it using the national press or social media. 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.

Is it best to argue a case for your position from within the organization or to resign in principle? I therefore choose an appropriate example when discussing con- cepts such as safety and dependability, system modeling, reuse, etc. An embedded system This is a system where the software controls some hard- ware device and is embedded in that device.

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

Enviado por Barbara flag Denunciar. Sortware is a relatively common condition in which the human pancreas is unable to produce sufficient quantities of a hormone called insulin.

The appropriate ethical posi- tion here depends on the views of the people involved.

The example of a data collection system that I use is a wilderness weather station. Others will work on mili- tary systems but not on weapons systems. The example of an information system used is a medical records system.

Engenharia de Software 3. The key requirements of such systems are reliability, even in hostile environ- mental conditions, and maintainability. Clearly, this depends on the people involved and the nature of the disagreement.

Some people feel strongly about these issues and do not wish to participate in any systems development associated with defense systems. 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. If you feel that there are problems with a software project, when do you reveal these problems to management? It can be considered from a engenhagia standpoint where the basic principles of ethics are considered and software engineering ethics are discussed with reference to these basic principles.

This is an integrated collection of software tools that are used to support some kind of activity.

They include ethical issues for technology users as well as developers. You must make up your own mind in these matters. I think that ethics are best discussed in a software engineering context and not as a subject in its own right. More recent texts such as that by Tavani Tavani introduce the notion of cyberethics and cover both the philosophical background so,merville practical and legal issues. The potential for damage, the extent of the damage, and sommefville people affected by the damage should influence the decision.

This is the approach taken by Laudon Laudon and Johnson Johnson
