[TIL] iOS 개발자 Skills Matrix

다음의 포스트를 참고하여 작성하였습니다.
iOS Developer Skills Matrix, (2022.01.09)
우리는 우리 자신이나 잠재적인 팀원들을 평가할 때 항상 객관적으로 최선을 다해야 합니다.
불행하게도, 우리는 질문에 더 정확하게 대답하려고 노력할수록 진리에서 더 멀어진다.
이 skill Matrix는 iOS 개발자 후보에 대한 상대적인 요구 사항을 정의하기 위한 시도입니다.
추구하는 점
- 어느 영역을 개선해야 할지 알 수 있을 정도의 정확함
- 특정 지식을 정식화하는 것을 피할 수 있을 정도의 모호함
Areas
대부분의 개발자는 매일 이 Skills Matrix의 여러 영역을 건드린다. 우리 대부분은 직장에서 모든 영역을 건드릴 기회가 없기 때문에 어떤 기술은 오랫동안 사각지대로 남아있을 수 있다. 그렇기 때문에 일하면서 하지 않는 것을 이 지표를 통해 공부하면서 나아갈 수 있다.
How not to use it
응시자 평가를 위한 전용 도구나 학습 계획으로 사용하지 마십시오. 이것들은 단지 지식의 지표, 트렌드입니다.
