I’ve found this set of tweets about the craftsmanship analogy by Sarah Mei: Just put my finger on why the craft/workshop metaphor for software development doesn't quite fit. — Sarah Mei (@sarahmei) July 25, 2015 "Craft" doesn't build any collaboration into the process, except in a top-down control-oriented way (master, journeyman, apprentice). — Sarah Mei (@sarahmei) July 25, 2015 "Craft" casts software development as an individual achievement, just as in a workshop, the master did all the important work on each piece.

We categorize an object’s peers (loosely) into three types of relationship. An object might have: Dependencies: Services that the object requires from its peers so it can perform its responsibilities. The object cannot function without these services.
