Finding the right level of service granularity is hard. 

The secret to getting granularity

right is understanding both granularity disintegrators (when to break apart a service)

and granularity integrators (when to put them back together), and analyze the corre‐

sponding trade-offs between the two.

 As illustrated in the previous scenarios, this

requires an architect to not only identify the trade-offs, but also to collaborate closely

with business stakeholders to analyze those trade-offs and arrive at the appropriate

solution for service granularity.
