    # LINE TODAY的大規模敏捷之路 - 陳岳澤 Derek Chen > 從這開始共筆,您可以分享任何聽到、學到的事物 > Scrum Master @ LINE Taiwan # Agenda - Why - The origin of story - How - Self-Designing team - LeSS adopation - What - 5 experiments in our process # LINE TODAY Background - Product Team - 40+ People - 1 PO team - 3 Dev teams - Process - Multiple product backlogs - Six-week Sprint - Small waterfall - Team lead assign work ## Six week Sprint Schedule - Week 1 : planning week. - Week 2 : Development - Week 3 : Feature Testing - Week 4 : Development - Week 5 : Feature Testing - Week 6: Regression Testing ## After one year 2019 - Challenges with Scale - 大象會亂走不會往同一個方向前進 ## Challenges - Trust:Stakeholder's requests take longer to deliver, so we lost their trust - Priority:我自己的需求是最重要的.有多個不同的PO,都認為自己的需求是重要的.需要搶優先序. - Complexity:越來越多的人加入後溝通成本上升 - Adapation:SM要保護團隊不受外界影響 - 一個小小的需求可能要 6+6 week後才能完成 ### Goals - Increase customer value - 以使用者為中心價值導向 - 一個 product backlog 的方式建立優先序 - Reduce waste and lead time - Form feature team - Reduce social conflict ## Self-Design team workshop - Trainings 教育訓練 - Forming 組建團隊 - 各各技能的熟練程度,寫在技能卡上 - 伙伴不是我想要一起工作的 - Reviewing - 每組 7-8人, Senior和 Junior要差不多 - 沒滿足要修正 - 約花三回合組成 feature team - Voting for Scrum Master Result: ![](https://hackmd.io/_uploads/HJo8slWPY.png) - 左邊是產品交付團隊 - 右邊是 PO team ## Large Scrum Scale adoption - LeSS Framework - PO 排 product backlog 優先順序 - LeSS 有一個重要的特性,把 sprint 拉齊 - Sprint Planning 1 做團隊 Level的分工合作 - Sprint Planning 2 由團隊內的組員討論 - Sprint Review 由所有團隊一請進行 - 之後會有 Retro,overall retro - Cross-team Coordination - Align the Development pace 對齊開發節奏.在 Sprint Planning, DailyScrum, Sprint Review, Retro 都對齊. - Demo togather 做整體產品的具焦 - Hold overall retrospective - Send scouts to other teams 參加別的團隊的 Daily看看有什麼可以帶回來 - Inter-team Coordination - 開發人員做 Coding - 測試人員寫測試案例 - 開發和測試是在一起做平行開發 - LeSS Principles - More with LeSS 少即是多 - 組織人越來越多會做什麼? - 需要更多階層?會有副作用,團隊成員溝通不順暢 - 需要更多角色?每個人對自己的責任感會更薄弱 - 需要更多流程?團隊會對所有權更薄弱 - 導入 LeSS 會更少交接 - Whole Product Focus - 整個產品能帶給客戶的好處和價值 - 唯一的PO(產品負責人)對產品做排序 - Focus on High-Value Work (因為排序的效果,可以讓PO發現有些事情根本不用進行) - Project: A Project -> B Project -> C Project -> D Project - Agile: A1->B1->C1->D1->A2... - System Thinking 整體動態的思考問題,做全局優化非局部優化 ### Backlog 數量和 e2e cycle time 的關聯性 ![](https://hackmd.io/_uploads/rky7l-ZvF.png) ## 5 experiments in our process ### one space vs more space #### Meeting in an open space - 一個白板討論很辛苦 - 會有干擾吵雜 - 但是會有別的團隊的專家一起討論 #### Meeting in separate room ![](https://hackmd.io/_uploads/SkoAl-ZvK.png) #### How does the team select stories? - Select by priorities and the same epics - 團隊會根據之前的經驗和story的順序進行挑選 ### How do we deal with online issues?(Experiment3) - From a maintence team - 每個團隊在一定時間內輪流進行維護工作 - 人員分兩半,一部份 maintance 另一部份開發 - 利用修復 Bug 的機會,讓每個人增加知識的廣度 ### 想下一代的產品需要做一些調整 - Have a Leading team and add new teams in area 慢慢的加入新團隊開發 ### Do we really need full time Scrum Master - 具焦的面向不同 Half time SM 兼職的 主要會在開發和SM的角色間快速切換 Full-time SM 全職的 主要會聚焦在教育訓練和組織的狀況 ## Summary - Why - increase customer value - Reduce waste and lead time - Form feature team - Reduce social cinflicts - How - Self-Desgning workshop - LeSS - What - 參考 ## 5 experiments in our process # Q&A - 重新組隊時,抵死不從的人後來怎麼了(不認同或不接受該重組或流程的) - 團隊是否符合遊戲規則 - 下一回改善 - 大家都是成年人 - 重新組團隊後,遇到了哪些混亂與技術上的挑戰? - 大家對流程不熟悉 - 大家要有開放的心願意試試看 - 多個團隊都是接同一個產品的功能,那各團隊的開發語言、框架、Know how,是否相同?如果是不同的情況下,要如何解決? - 開發語言基本上是一致的 - 橫向團隊會自己分享幫助他人 - 加強知識的廣度和深度 - 好奇的問,你們在跑LESS, 一開始分完團隊,這個團隊的陣型就固定下來?還是你們多久會切換一次團隊成員? - 第一次自由組隊 - 接下來讓 team lead 做分配 - 依據您的介紹,LINE的設計師(UI/UX Designer)歸屬於PO team而非Dev. Team。請問貴公司的設計師都是如何與 Dev. Team 合作的?是以waterfall 方式預先設計好產品規格後才交給Dev Teams 以多個 Sprints開發嗎?或是有其他合作方式? - Designer 會領先半個到一個 sprint. - 請問老師,有沒有什麼型態的團隊不適用less,例如傳產? - 適用 LeSS的領域非常稀有 - 產品屬於一百多人或更多人 - 團隊一開始要小不要大,成長後才考慮 LeSS - planning 從一開始的一週, 變成一天, 這樣的設計會完整嗎? 不周詳的plannig, 會不會造成開發中, 才發現有問題, 導致打掉重做 - 邊做邊學
