By Adam Smith, labour division can make you by 240 times more effective (on example of a pin factory producing pins in 18 steps).
Why then are multi-skilled roles are so in demand if this actually reduces productivity - or was Smith just wrong, why then?
Searches for "fullstack developer" still trend on Google, however apparently slower than two years ago:
=====
To sum up, a full stack developer would be able do virtually all the value chain (correct me if I am wrong):
- Discuss with customers and refine workable agile requirements for his part of the job
- Decide which architecture, tooling and components pick up - just give him a notebook
- Write code for frontend, backend, ingration, which is cross device compatile and does not requrire much testing, or includes it
- Profile and scape data, use Cloud AI/ML APIs for advanced features
- Write up required IaC code and rollout
- Be on call in case of error or sales processes
- Be aware of security relevant design, overall patching, migration and modernization
- Account time table in a scroutinized way to ease invoicing of the employer
- ... did I forget anything?
