Option B allows for more coherence and is a more effective way of integrating contributions by different people or research groups. Option A is most often used when several pivotal studies with distinct contributions form the foundation of the literature review and deserve their own dedicated sections. Option B, however, is more challenging to write because it depends on your ability to synthesize information effectively. Sometimes, a combined approach is appropriate: one paper may contribute significantly to one area, although other papers might also add to knowledge in that area.

The increasing concern for the value dimension of engineering is, at least in part, a result of the attention that the media has given to cases such as the Challenger disaster, the Kansas City Hyatt-Regency Hotel walkways collapse, and the Exxon oil spill. As a response to this concern, a new discipline, engineering ethics, is emerging. This discipline will doubtless take its place alongside such well-established fields as medical ethics, business ethics, and legal ethics. The problem presented by this development is that most engineering professors are not prepared to introduce literature in engineering ethics into their classrooms. They are most comfortable with quantitative concepts and often do not believe they are qualified to lead class discussions on ethics. Many engineering faculty members do not think that they have the time in an already overcrowded syllabus to introduce discussions on professional ethics, or the time in their own schedules to prepare the necessary material. Hopefully, the resources presented herein will be of assistance.
