고객을 어떻게 나눌까?

  • 가령 운영중인 사이트가 **고객고유번호(user_id)**를 임의의 정수로 관리되고 있는 상태다.
  • 상품 소개 화면에서 구매버튼을 누르면 결제화면으로 넘어가는데,
  • 버튼 색깔에 변화를 줘서 테스트 하고 싶다.
  • 10%의 사용자에게는 빨간버튼을 보여주고,
  • 또 다른 10%의 사용자에게는 파란버튼을 보여주고,
  • 나머지 사용자에게는 원래버튼을 보여주고 싶다. 고객을 어떻게 나눌까?
  • **고객고유번호(user_id)**를 10으로 나눈 나머지는 0부터 9까지다.
  • 이 나머지 값이 같은 사용자끼리 같은 그룹으로 묶는다. 그룹0, 그룹1, ..., 그룹9.
  • 그룹0은 테스트 A로 그룹1는 테스트 B로 지정하고 싶다고 가정하자.
