Chapter 1, “Introduction to SharePoint 2013,” discussed the spectrum of SharePoint developers and the different ways in which they use SharePoint. As a reminder, you can divide this spectrum into the following:
Thinking about a life cycle around each of these personas, you can imagine ways in which these people might work together or act independently on something that was created for or by them. For example, the end user is the ultimate consumer of what exists out of the box. Meanwhile, the developer builds apps and the designer brands and builds the user experience for the SharePoint sites that the power user configures, thus the end users are downstream from the development process. Further upstream, you have the developer and the designer who might work together (and in some cases are the same person) to deliver both the code and the user experience, branded or otherwise, to the power user and ultimately to the end user. The point is that a range of people interact with SharePoint — from the developer all the way downstream to the end user — you can see a representation of this in Figure 3-1.
