INTERCHANGEABILITY
LOCK-IN ==> #Also called "product-dependent architecture"
#Low interchangeability:
# - i.e. high switching cost|barriers
# - can be perceived only, e.g. because of sunk cost
#Can be pushed by:
# - a vendor, in order to increase revenue
# - called "vendor|proprietary lock-in" or "connector conspiracy"
# - wolf ticket:
# - vendor declaring using standards, but actually doing different implementation, i.e. vendor lock-in
# - can be defeated with standards test suite or certification
# - the technology itself ("technology lock-in")
# - e.g. QWERTY keyboards
GOLDEN HAMMER ==> #Making much worst architecture choices in order to avoid switching costs
#I.e. trying to fit existing tools/architecture into new requirements although it badly fits
#E.g.: using Excel for everything
#Usually pushed by vendors using vendor lock-in
