The Big Cloud Exit FAQ by @dhh
This isn’t some archaic knowledge that’s been lost to the ages. We might not know exactly how the pyramids were built, but we do still know how to connect a Linux machine to the internet.

회사와 팀의 align을 위한 키워드: 반복 & 대화 by Hoon Lee
“회사의 중요한 지표 및 프로젝트는 매주, 자주 반복하여 팀에게 설명하고 또 설명한다. 반복을 멈추지 않는다.”
“반복하다 보면, 그 내용에 대해 질문하는 팀원이 생긴다. 그러면 대화를 한다.”
반복과 대화. 회사와 팀의 align 을 만들어 주는 가장 중요한 2가지 키워드라 생각한다.

You can't make decisions based on a game that doesn't exist by Woojin Kim
Don not let them make decisions based on a game that doesn't exist.
Original in Korean:

Do we need non disruptive maintenance? by Woojin Kim
While, theoretically, non-disruptive updates can be an avenue to optimize your company's revenue, there exist several costs, beyond technical aspects, that might render maintaining the current trajectory a more judicious choice. Even if the execution is technically feasible, the practicality of implementing such updates may not always align with the company's best interests. This is especially true when considering the manpower needed for verifications, the associated time consumption, the varying feasibility across different game genres, and the expenses involved in retraining the staff.
Original in Korean:
무중단 업데이트는 이론적으로 회사의 수익을 극대화 할 수 있는 방법이지만 기술적인 측면을 생략하고서도 여기에 필요한 여러 가지 비용이 있으며 이를 감안하면 현재 체계를 유지하는 쪽이 더 나은 선택일 가능성도 있습니다. 기술적으로 가능하더라도 점검 과정을 수행하는 인력, 점검 시간에 따른 손해, 게임 장르에 따른 무중단 달성 가능 여부, 스탭들에 대한 재교육 비용 등을 고려할 때 무중단이 항상 이익이 아닐 수 있습니다.
68 Bits of Unsolicited Advice by Kevin Kelly
Always demand a deadline. A deadline weeds out the extraneous and the ordinary. It prevents you from trying to make it perfect, so you have to make it different. Different is better.
Why an Engineering Manager Should Not Review Code
- Technical Lead and Engineering Manager are two roles that partner to make the teamwork. Therefore, they should have clear roles and responsibilities and cooperate in a mutual partnership.
- Teams hit a size inflection point of ~4 where someone must dedicate their time to communications for the team to work. Otherwise, the team collapses into a black hole of thrash.
Delivering 80% of a project as soon as possible can be more beneficial for your team and your own development than striving for 100% completion by the deadline.
- 팀장님을 잘 활용하자,
- 100% 를 on-time 에 전달하기 보다는, 80%를 한 템포 빠르게 공유하여 피드백을 빨리 받고 반영하여 완성도를 높이자

On Wall Street, many employees viewed the company as a pain, and in big tech, many viewed the company as a family - neither of which is a healthy relationship.
Original full korean: 월가에서는 많은 직원들이 회사를 고통으로 여겼고 빅테크에서는 많은 직원들이 회사를 가족으로 여겼다. 그 어느 쪽도 건강한 회사와 관계는 아니다. 그 중심 밸런스는 본인이 잡아야 한다. 나의 목표와 회사의 목표에 접점이 있으면 서로 최선을 다한다. 회사 목표에 나의 모든 것을 꾸겨 넣을 이유도 없고 회사가 나에게 맞추기를 어리석게 바랄 이유도 없다.

- You must not do anything that cannot affect your business. At least it can't have a higher priority.
- No matter what you do, the results should be measurable.
- Every moment we have to think about what can be improved to increase the Y value the fastest and most significantly.
- Individual engineers should feel weird about not measuring and ask questions.
2022 센드버드 오픈 오피스 아워 ㅣ글로벌 B2B 스타트업을 만들기 위한 20 Quesetions 를 보고 인상깊었던 답변 내맘대로 정리
Q. 고객사의 커스텀 개발 요청을 어떤 기준으로, 어디까지 수용해야할까요? 제품 이점이 명확하게 강화되고 추가 고객사 확보가 가능하다면 수용하는 편입니다. 피드백 바탕으로 제품 개발하는 것은 중요한 지점인데 팀에서는 SI라고 생각하는 경우가 있어서요. 비슷한 맥락에서 고객의 목소리/요구사항에서 무엇을 반영하고(우선순위화하고), 무엇을 안 할지 정하는 기준은 무엇일까요? 그대로 다 만들 수도 없을 것이고 그렇게 하는게 좋은 제품을 만드는 길은 아닐듯해 어떻게 취사선택할지 고민이 됩니다.
A. 너무 고민하지 말고 해봐. 말은 우아하지만 현실은 그렇게 우아하지 않다. 고민하고 실망하고 하는 과정에서 조직에 직관이 생긴다.

Q. 한국 및 미국에서 요금제 구성 및 가격 최적화는 누가(콘트롤 타워) 어떤 방식으로 진행했는지 궁금합니다.
A. 창과 방패의 싸움, 영업을 위해서는 고객에게 할인을 해주어야하고, 그러면 서버는 최적화하고, 최적화하고 나면 할인할 여유가 생기고… 유지하기 힘듬, 실제로 회사 밸류에이션이나 캐시플로우에 많은 영향을 줌. 지지부진한 싸움이긴 하지만 버텨야 함. 화이팅!
