“Tell me how you measure me, and I will tell you how I
will behave” – Eliyahu M. Goldratt
Celebrating vanity metrics is fun.
Metrics are a way to know in what direction something is going,
in order to take informed next steps. Quantitative metrics enable
clear-cut numerical analysis with direct indicators, while qualitative
metrics enable subjective study about some user behaviour, opinion or expectation. These two types of metrics complement each other.
This chapter will call out measurement antipatterns to look out
for with a short story each. We will discuss some light theory as to
why we believe each is an antipattern, followed by some concrete
patterns and practices to experiment with.
