Build Vs Buy Table

build-v-buy.md

	Build	Buy
Pro	Tight integration into your code base Uses existing metrics and data, including custom metrics Aware of advanced caching Easy to target audiences	Almost immediately able to test Proven statistics engine Self-service front end testing admin - testing may done by non technical teams Slick admin interface Very easy to use New features rolled out independently of your team
Con	High opportunity costs to build High maintenance costs Generally poor user experience Takes months to build right High risks for incorrect results Have to build trust No self-service front end testing Engineering often required to implement tests	Ongoing subscription costs - some platforms can be expensive Limited integration with code base Yet another place for user data 3rd party tracking often blocked Most only support binomial metrics Front end testing can cause flickering Limited customization - not all tests can be run Sometimes there can be “too many cooks” running A/B tests
