For example, if you disagree, in principle, with the policies of more senior management in the company, how should you react? Equally, if an employee is taken on and makes clear that he or she does not wish to work on such systems, employers should not exert pressure to do so at some later date. 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 example of a data collection system that I use is a wilderness weather station.

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. 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. 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 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 The system types soctware I use as case studies are: Is it best to argue a case for your position from within the organization or to resign in principle?

A difficult situation for professional engineers arises when their employer acts in an unethical way. Issues in embedded systems typi- cally include physical size, responsiveness, and power management, enfenharia.

Although the system may not have been validated according to predefined criteria, these criteria may be too strict. The key requirements of such systems are reliability, even in hostile environ- mental conditions, and maintainability. Enviado por Barbara flag Denunciar.

This is an integrated collection of software tools that are used to support some kind of activity. Programming environments, such as Eclipse Vogel will be the most familiar type of environment for readers of this book.

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

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. 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.

It can be considered from a edocao standpoint where the basic principles of ethics are considered and software engineering ethics are discussed with reference to these basic principles.

Insulin metabolizes glucose sugar in the blood. 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. We all face such ethical dilemmas in enyenharia professional lives, and, fortunately, emgenharia most cases they are either relatively iaan or can be resolved without too much dif- ficulty.

The example of an embedded system that I use is a software system to control an insulin pump for people who have diabetes. If you feel that there are problems with a software softeare, when do you reveal these problems to management? Issues in information systems include security, usability, privacy, and maintaining data integrity. This is the approach taken by Laudon Laudon and Johnson Johnson Where they cannot be resolved, the engineer is faced with, perhaps, another problem.


The principled action may be to resign from their job, but this may well affect others such as their partner or their children. I therefore choose an appropriate example when discussing con- cepts such as safety and dependability, system modeling, reuse, etc.

If the situation is very dangerous, it may be justified to publicize it using the national press or social media. It is also the case that, even when properly validated, the system may fail and cause an accident. The potential for damage, the extent of the damage, and the people affected by the damage should influence the decision.

An embedded system This is a system where the software controls some hard- ware device and is embedded in that device.

Another ethical issue is participation in the development of military and nuclear systems. In any situation where different people have different views and objectives, you are likely to be faced with ethical dilemmas. However, you should always try to resolve the situation while respecting the rights of your employer. 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 information system The primary purpose of this type of system is to manage and provide access sommerviloe a database of information.

Some people feel strongly about these issues and do not wish to participate in any systems development associated with defense systems. They include ethical issues for technology users as well as developers.

The system may actually operate safely throughout its life- time. The software sommervikle 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.
