Practice and method are key elements to successful digital technology implementation. In the context of this book, practice is a term which usually refers to the conduct as well as the work of someone from the profession associated with digital technology whereas method is a process by which a task is completed. Codes of conduct are the traditional instruments of guidance for acceptable professional practice. However, there are other methods of promoting good practice. There are two aspects to realising ethical digital technology implementation: to resist the temptation to perform unethical practice and to reduce the opportunity of performing unethical practice. These are addressed either reactively, where the measure is in response to a particular event or circumstance, or proactively, where the measure is an attempt to promote desired future behaviour. The latter is more important as it will lead to lasting positive change. This complex field is explored in this chapter. A wide range of digital technology applications, some with associated problematic incidents are discussed. These discussions include possible changes in practice or method to ensure that particular ethical problems are unlikely either to go unnoticed or to reoccur in the future.
