The Authors@IEEE Newsletter in their October issue proposed a few useful tips for the crafting of your article Introduction.

A well-written introduction can convince a busy researcher to invest time in reading your article. Craft a better introduction by following these tips:

• Structure your introduction like a funnel, moving from broad to narrow: start by identifying the broad area of a study, continue to a narrower focus on a literature review of your specific research area, and then to an even narrower focus on your specific research question
• Include a comprehensive but concise literature review; provide enough information to establish a context for your work but avoid including studies that are only marginally relevant
• Clearly state your research question and why it’s important to the field
• Briefly explain your method for approaching the problem and why you chose that method
