Common principle sets
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
know typical principle families and apply them to design.
Planned topics
- Standardization: reuse approved platforms and patterns to cut cost and risk.
- Interoperability: integrate through published interfaces and open standards.
- Security: protect data by design, least privilege, defense in depth.
- Evolvability: change parts without changing everything; loose coupling at boundaries.
- Others: data as an asset, business continuity, simplicity.
Draft outline details
Demonstration
table mapping each family to a Larkspur decision: standardization → one API style; interoperability → carriers integrate via standard APIs; security → tokenized card data only; evolvability → ERP access behind an anti-corruption layer.
Check your understanding
Which family would justify putting the ERP behind an interface layer?
Show answer
Evolvability, supported by interoperability.
