Mifumo ya zamani ni isiyofahamika lakini mara nyingi ni muhimu, inaendesha biashara. Uamuzi wa kurekebisha, kubadilisha, au kuondoa lazima ukabidhiwe na gharama na thamani, sio kwa chuki ya msimbo wa zamani. "Ni lumambi na makubwa" si sababu; "inatukamatia" ni.
Mwongozo wa uamuzi
REFACTOR (improve in place) when:
- Core logic is sound; it's holding business value
- Problems are localized; you can improve incrementally
REPLACE (rewrite/migrate) when:
- It blocks important work and can't be incrementally fixed
- Maintenance cost > rebuild cost over a sensible horizon
- It's a growing security or reliability liability
RETIRE (remove entirely) when:
- Its value no longer justifies any maintenance cost
- Usage has dwindled; a simpler path exists
