Summary
In this chapter, we looked at three use cases of self-service analytics. One was about world indices, one was about traffic-light violations, and the last one used distance measures to find the radius within which a house could be located given some key variables. Our main takeaway was that you should always start by planning your work, then get to know the data, use descriptive statistics, and adjust your plan according to your intermediate results.
A dashboard is never really finished: you can always change things; your audience might change; stakeholder wishes might differ. Deliver a working visualization with basic functionality and continue to develop after you get feedback. Depending on your backlog or other circumstances, the basics might be enough.
The next chapter will be all about improving performance. With more and more data, performance is key and could mean the difference between success and failure.
