Introduction

The introduction starts in a broad way, tries to capture the reader’s interest, and then narrows to the thesis sentence. Here’s one example of a way to introduce the thesis on 21st century workforce skills:

Have you ever been told that you have to learn a new computer application at work—now!? Is your department at work constantly being reorganized? Are you expected to participate in multiple work teams, on a variety of tasks? Welcome to the 21st century world of work. It’s a very different world than our grandparents experienced; very few people learn one job and perform it until they retire. The 21st century workplace, given its uncertain and thus flexible nature, requires a special set of skills. [thesis sentence]
