/metrics-review $ARGUMENTS
```

## 工作流程

### 1. 蒐集指標資料

如果 **~~product analytics** 已連接:
- 抓取相關時間區間的關鍵產品指標
- 取得比較資料(上一期、去年同期、目標)
- 有的話一併抓取分群拆解

如果沒有連接任何分析工具,請使用者提供:
- 指標和它們的數值(貼表格、貼截圖,或口頭描述都可以)
- 比較資料(上一期、目標)
- 近期變動的背景(上線、事故、季節性)

詢問使用者:
- 要檢視哪個時間區間?(上週、上個月、上一季)
- 要聚焦哪些指標?還是要把整套產品指標都看一遍?
- 有沒有特定的目標或目標值可以拿來比?
- 有沒有已知事件可以解釋這些變化(上線、當機、行銷活動、季節性)?

### 2. 整理指標

用指標階層來組織這份檢視:最上面是 North Star 指標,接著是 L1 健康指標(獲客、啟用、參與、留存、營收、滿意度),再來是供往下鑽研的 L2 診斷指標。完整定義請見下方的**產品指標階層**。

如果使用者還沒定義自己的指標階層,先幫他們找出 North Star 和關鍵 L1 指標,再往下做。

### 3. 分析趨勢

針對每個關鍵指標:
- **目前數值**:這個指標現在是多少?
- **趨勢**:跟上一期比,是上升、下降還是持平?時間跨度多長?
- **對照目標**:跟目標比起來如何?
- **變化速率**:趨勢是在加速還是減速?
- **異常**:有沒有突然的變化、暴增或暴跌?

找出關聯:
- 某個指標的變化,是否跟另一個指標的變化相關?
- 有沒有領先指標可以預測落後指標的變化?
- 分群拆解後,會不會發現整體趨勢其實是由某個特定 cohort 帶動的?

### 4. 產出檢視報告

#### 摘要
2 到 3 句話:整體產品健康度、最值得注意的變化、重點提醒。

#### 指標計分卡
用表格呈現,方便快速掃過:

| Metric | Current | Previous | Change | Target | Status |
|--------|---------|----------|--------|--------|--------|
| [Metric] | [Value] | [Value] | [+/- %] | [Target] | [On track / At risk / Miss] |

#### 趨勢分析
針對每個值得討論的指標:
- 發生了什麼,變化有多大
- 可能的原因(根據已知事件、相關指標、分群分析來歸因)
- 這是一次性事件,還是持續的趨勢

#### 亮點
哪些地方做得好:
- 超越目標的指標
- 值得持續的正向趨勢
- 表現強勁的分群或功能

#### 需要關注的地方
哪些地方需要留意:
- 沒達標或走勢向下的指標
- 還沒變成問題之前的早期警訊
- 我們看不清楚或不了解的指標

#### 建議行動
根據分析提出具體的下一步:
- 要做的調查(深入挖掘令人擔心的趨勢)
- 要啟動的實驗(針對可能改善某指標的假設做測試)
- 要投入的資源(對有效的做法加碼)
- 要設的警報(更密切監控某個指標)

#### 背景與注意事項
- 已知的資料品質問題
- 影響可比性的事件(當機、假日、上線)
- 我們該追蹤但還沒追蹤的指標

### 5. 後續追蹤

產出檢視報告之後:
- 問使用者有沒有哪個指標需要更深入的調查
- 主動提議為持續監控建立 dashboard 規格
- 主動提議針對需要關注的地方草擬實驗提案
- 主動提議建立可重複使用的指標檢視範本

## 產品指標階層

### North Star 指標
最能代表你的產品帶給使用者核心價值的那一個指標。它應該:

- **與價值一致**:使用者從產品得到更多價值時,它就會動
- **具領先性**:能預測長期的商業成功(營收、留存)
- **可行動**:產品團隊的工作可以影響它
- **好懂**:公司裡每個人都能理解它的意思和重要性

**依產品類型舉例**:
- 協作工具:每週有 3 位以上成員貢獻內容的活躍團隊數
- 市集(Marketplace):每週完成的交易數
- SaaS 平台:每週完成核心工作流程的活躍使用者數
- 內容平台:每週的有效閱讀/觀看時間
- 開發者工具:每週使用該工具的部署次數

### L1 指標(健康指標)
5 到 7 個指標,合起來能完整描繪產品的健康狀況。它們對應使用者生命週期的關鍵階段:

**獲客(Acquisition)**:新使用者有找到這個產品嗎?
- 新註冊或試用開始數(量和趨勢)
- 註冊轉換率(訪客到註冊)
- 通路組成(新使用者從哪裡來)
- 每次獲客成本(付費通路)

**啟用(Activation)**:新使用者有到達價值時刻嗎?
- 啟用率:完成能預測留存的關鍵動作的新使用者比例
- 啟用所需時間:從註冊到啟用要多久
- 設定完成率:完成引導步驟的比例
- 首次價值時刻:使用者第一次體驗到產品核心價值的時間點

**參與(Engagement)**:活躍使用者有得到價值嗎?
- DAU / WAU / MAU:不同時間尺度的活躍使用者
- DAU/MAU 比率(黏著度):每月使用者中有多少比例每天都會回來
- 核心動作頻率:使用者做最重要的那件事有多頻繁
- Session 深度:使用者每次使用會做多少事
- 功能採用率:使用關鍵功能的使用者比例

**留存(Retention)**:使用者有回來嗎?
- D1、D7、D30 留存:1 天、7 天、30 天後回訪的使用者比例
- Cohort 留存曲線:每一批註冊 cohort 的留存如何演變
- 流失率:每一期流失的使用者或營收比例
- 回流率:已流失使用者中回來的比例

**變現(Monetization)**:價值有轉換成營收嗎?
- 轉換率:免費轉付費(freemium 模式)
- MRR / ARR:月經常性營收或年經常性營收
- ARPU / ARPA:每位使用者或每個帳號的平均營收
- 擴張營收:來自既有客戶的營收成長
- 淨營收留存:含擴張與縮減的營收留存

**滿意度(Satisfaction)**:使用者覺得這個產品怎麼樣?
- NPS:淨推薦值(Net Promoter Score)
- CSAT:顧客滿意度(Customer Satisfaction Score)
- 客服工單量與處理時間
- App store 評分與評論情緒

### L2 指標(診斷)
用來調查 L1 指標變化的細部指標:

- 每個步驟的漏斗轉換率
- 功能層級的使用與採用情形
- 特定分群的拆解(依方案、公司規模、地區、使用者角色)
- 效能指標(頁面載入時間、錯誤率、API 延遲)
- 特定內容的參與度(哪些功能、頁面或內容類型帶動參與)

## 常見產品指標

### DAU / WAU / MAU
**衡量什麼**:在一天、一週或一個月內執行符合條件動作的不重複使用者。

**關鍵決策**:
- 什麼才算「活躍」?登入?瀏覽頁面?核心動作?要仔細定義,因為不同定義會說出不同的故事。
- 哪個時間尺度最重要?每天使用的產品(通訊、email)看 DAU。每週使用的產品(專案管理)看 WAU。使用頻率較低的產品(報稅軟體、訂旅遊)看 MAU。

**怎麼使用**:
- DAU/MAU 比率(黏著度):高於 0.5 代表有每天使用的習慣。低於 0.2 表示不常使用。
- 趨勢比絕對數字重要。活躍使用量是在成長、持平還是下滑?
- 依使用者類型分群。重度使用者和輕度使用者的行為差很多。

### 留存(Retention)
**衡量什麼**:在 X 期開始使用的使用者,有多少比例在 Y 期仍然活躍?

**常見的留存時間點**:
- D1(隔天):第一次體驗夠不夠好,讓人願意回來?
- D7(一週):使用者有沒有養成習慣?
- D30(一個月):使用者有沒有被長期留住?
- D90(三個月):這是不是一位穩固的使用者?

**怎麼使用留存**:
- 依 cohort 畫留存曲線。要看的是:一開始就大量流失(啟用問題)、持續穩定下滑(參與問題),或是趨於平緩(很好,代表你有一群穩定的留存使用者)。
- 比較不同時期的 cohort。新的 cohort 留存比舊的好嗎?那代表產品改進有效。
- 依啟用行為拆解留存。完成引導的使用者 vs 沒完成的。用過功能 X 的使用者 vs 沒用過的。

### 轉換(Conversion)
**衡量什麼**:從一個階段進到下一個階段的使用者比例。

**常見的轉換漏斗**:
- 訪客到註冊
- 註冊到啟用(關鍵價值時刻)
- 免費到付費(試用轉換)
- 試用到付費訂閱
- 月繳到年繳方案

**怎麼使用轉換**:
- 把完整漏斗畫出來,量測每一步的轉換率
- 找出最大的流失點,這些就是槓桿最高的改善機會
- 依來源、方案、使用者類型拆解轉換。不同分群的轉換差很多。
- 追蹤轉換隨時間的變化。隨著你迭代體驗,它有在進步嗎?

### 啟用(Activation)
**衡量什麼**:新使用者中,到達第一次體驗產品核心價值那個時刻的比例。

**定義啟用**:
- 比較留存的使用者和流失的使用者。留存的使用者做了哪些流失者沒做的動作?
- 啟用事件應該對長期留存有很強的預測力
- 應該在第一個 session 或最初幾天內就能達成
- 例如:建立第一個專案、邀請一位隊友、完成第一個工作流程、連接一個整合

**怎麼使用啟用**:
- 每一批註冊 cohort 都要追蹤啟用率
- 量測啟用所需時間,越快幾乎都越好
- 設計引導流程,帶使用者走到啟用時刻
- 對啟用流程做 A/B 測試,並量測對留存的影響,不要只看啟用率

## 目標設定框架

### OKR(目標與關鍵結果)

**Objective(目標)**:定性、有企圖心的目標,描述你想達成什麼。
- 能激勵人心、容易記住
- 有時間限制(每季或每年)
- 講方向,不綁特定指標

**Key Results(關鍵結果)**:定量的衡量,用來判斷目標有沒有達成。
- 具體、可衡量
- 有時間限制,有明確的目標值
- 以成果為基準,不是以產出為基準
- 每個 Objective 配 2 到 4 個 Key Results

**範例**:
```
Objective: Make our product indispensable for daily workflows

Key Results:
- Increase DAU/MAU ratio from 0.35 to 0.50
- Increase D30 retention for new users from 40% to 55%
- 3 core workflows with >80% task completion rate
```

### OKR 最佳實務
- OKR 要設得有企圖心但做得到。挑戰型(stretch)OKR 的目標是達成 70%。
- Key Results 要衡量成果(使用者行為、商業結果),不要衡量產出(上線的功能數、完成的任務數)。
- 不要設太多 OKR。2 到 3 個 Objective、每個配 2 到 4 個 KR 就很夠了。
- OKR 應該要讓人不舒服。如果你有信心全部都能達成,代表不夠有企圖心。
- 在期中檢視 OKR。如果有些 KR 明顯落後,就調整人力分配。
- 期末要誠實地給 OKR 打分。0.0-0.3 = 未達成,0.4-0.6 = 有進展,0.7-1.0 = 達成。

### 設定指標目標
- **基準線(Baseline)**:目前的數值是多少?設目標之前,你需要一條可靠的基準線。
- **標竿(Benchmark)**:同類產品做到什麼程度?業界標竿能提供參考脈絡。
- **軌跡(Trajectory)**:目前的趨勢如何?如果這個指標本來就每月進步 5%,那 6% 的目標就不算有企圖心。
- **投入(Effort)**:你在這件事上投入多少資源?賭注越大,目標就該越積極。
- **信心(Confidence)**:你對達成目標有多少把握?設一個「承諾值」(高信心)和一個「挑戰值」(有企圖心)。

## 指標檢視的節奏

### 每週指標檢查
**目的**:快速抓出問題、監控實驗、掌握產品健康狀況。
**時間**:15 到 30 分鐘。
**參與者**:產品經理,可能加上工程負責人。

**要檢視的內容**:
- North Star 指標:目前數值、週對週變化
- 關鍵 L1 指標:任何明顯的波動
- 進行中的實驗:結果與統計顯著性
- 異常:任何意外的暴增或暴跌
- 警報:任何觸發監控警報的項目

**行動**:如果有什麼不對勁,就去調查。否則記下來,繼續往前。

### 每月指標檢視
**目的**:更深入地分析趨勢、對照目標的進度、策略上的含意。
**時間**:30 到 60 分鐘。
**參與者**:產品團隊、關鍵利害關係人。

**要檢視的內容**:
- 完整的 L1 指標計分卡,附月對月趨勢
- 對照季度 OKR 目標的進度
- Cohort 分析:新的 cohort 表現比較好嗎?
- 功能採用率:最近的上線表現如何?
- 分群分析:不同使用者分群之間有沒有分歧?

**行動**:找出 1 到 3 個要調查或投入的方向。如果指標揭露了新資訊,就更新優先順序。

### 季度業務檢視(Quarterly Business Review)
**目的**:策略層級地評估產品表現,為下一季設定目標。
**時間**:60 到 90 分鐘。
**參與者**:產品、工程、設計、管理層。

**要檢視的內容**:
- 本季的 OKR 評分
- 本季所有 L1 指標的趨勢分析
- 年對年比較
- 競爭態勢:市場變化與競爭對手動向
- 哪些有效、哪些沒效

**行動**:設定下一季的 OKR。根據資料顯示的結果調整產品策略。

## Dashboard 設計原則

### 有效的產品 dashboard
好的 dashboard 能讓人一眼回答「產品現在表現如何?」這個問題。

**原則**:

1. **從問題開始,不是從資料開始**。這個 dashboard 要支援哪些決策?從決策倒推來設計。

2. **資訊要有層級**。最重要的指標要在視覺上最顯眼。North Star 放最上面,接著是 L1 指標,L2 指標放在往下鑽研的層級。

3. **脈絡比數字重要**。沒有脈絡的數字沒有意義。一律要呈現:目前數值、比較基準(上一期、目標、標竿)、趨勢方向。

4. **指標少一點,洞察多一點**。有 50 個指標的 dashboard 對誰都沒幫助。聚焦在重要的 5 到 10 個,其他的放進詳細報告。

5. **時間區間一致**。同一個 dashboard 上的所有指標用同樣的時間區間。把日指標和月指標混在一起會造成混亂。

6. **視覺化的狀態指示**。用顏色讓人一眼看出健康狀況:
   - 綠色:正常或持續改善
   - 黃色:需要留意或持平
   - 紅色:偏離軌道或下滑

7. **可行動性**。dashboard 上的每個指標都應該是團隊能影響的。如果你無法對它採取行動,它就不屬於產品 dashboard。

### Dashboard 版面

**第一列**:North Star 指標,附趨勢線和目標。

**第二列**:L1 指標計分卡,每個關鍵指標的目前數值、變化、目標、狀態。

**第三列**:關鍵漏斗或轉換指標,用視覺化漏斗呈現每個階段的流失。

**第四列**:近期的實驗與上線,包括進行中的 A/B 測試,以及剛上線功能的早期指標。

**底部/往下鑽研**:L2 指標、分群拆解,以及供調查用的詳細時間序列。

### Dashboard 反模式
- **虛榮指標**:永遠只會往上漲、卻不代表健康狀況的指標(累計註冊總數、累計頁面瀏覽量)
- **指標太多**:需要捲動才看得完的 dashboard。如果一個畫面放不下,就砍指標。
- **沒有比較基準**:只有原始數字沒有脈絡(有目前數值,卻沒有上一期或目標)
- **過時的 dashboard**:已經好幾個月沒更新或沒人檢視的指標
- **產出型 dashboard**:衡量團隊活動(關掉的工單數、merge 的 PR 數),而不是使用者和商業成果
- **一個 dashboard 給所有受眾**:主管、PM 和工程師需要不同的視角。一體適用行不通。

### 警報
為需要立即處理的指標設警報:

- **門檻警報**:指標低於或高於關鍵門檻(錯誤率 > 1%、轉換率 < 5%)
- **趨勢警報**:指標連續多天/多週持續下滑
- **異常警報**:指標明顯偏離預期範圍

**警報衛生**:
- 每個警報都應該是可行動的。如果你對它無能為力,就不要為它設警報。
- 定期檢視並調整警報。誤報太多,大家就會忽略所有警報。
- 每個警報都要指定負責人。警報響了誰來處理?
- 設定適當的嚴重等級。不是每件事都是 P0。

## 輸出格式

計分卡用表格。狀態指示要清楚。摘要要精簡,讀者應該在 30 秒內掌握最重要的故事。

## 小技巧

- 從「所以呢」開始:這份指標檢視裡最重要的一件事是什麼?先講它。
- 沒有脈絡的絕對數字沒有用。一律呈現比較基準(對上一期、對目標、對標竿)。
- 歸因要小心。相關不等於因果。如果某個指標動了,要承認你對原因並不確定。
- 分群分析常常會發現,整體指標掩蓋了重要的差異。整體持平的數字,可能藏著一個分群在成長、另一個分群在萎縮。
- 不是每個指標的波動都重要。小幅起伏是雜訊。把注意力放在有意義的變化上。
- 如果某個指標沒達標,不要只回報沒達標,還要建議該怎麼辦。
- 指標檢視應該推動決策。如果檢視之後沒有至少一個行動,就代表它沒有用。

# Metrics Review

> If you see unfamiliar placeholders or need to check which tools are connected, see [CONNECTORS.md](../../CONNECTORS.md).

Review and analyze product metrics, identify trends, and surface actionable insights.

## Usage

```
/metrics-review $ARGUMENTS
```

## Workflow

### 1. Gather Metrics Data

If **~~product analytics** is connected:
- Pull key product metrics for the relevant time period
- Get comparison data (previous period, same period last year, targets)
- Pull segment breakdowns if available

If no analytics tool is connected, ask the user to provide:
- The metrics and their values (paste a table, screenshot, or describe)
- Comparison data (previous period, targets)
- Any context on recent changes (launches, incidents, seasonality)

Ask the user:
- What time period to review? (last week, last month, last quarter)
- What metrics to focus on? Or should we review the full product metrics suite?
- Are there specific targets or goals to compare against?
- Any known events that might explain changes (launches, outages, marketing campaigns, seasonality)?

### 2. Organize the Metrics

Structure the review using a metrics hierarchy: North Star metric at the top, L1 health indicators (acquisition, activation, engagement, retention, revenue, satisfaction), and L2 diagnostic metrics for drill-down. See **Product Metrics Hierarchy** below for full definitions.

If the user has not defined their metrics hierarchy, help them identify their North Star and key L1 metrics before proceeding.

### 3. Analyze Trends

For each key metric:
- **Current value**: What is the metric today?
- **Trend**: Up, down, or flat compared to previous period? Over what timeframe?
- **vs Target**: How does it compare to the goal or target?
- **Rate of change**: Is the trend accelerating or decelerating?
- **Anomalies**: Any sudden changes, spikes, or drops?

Identify correlations:
- Do changes in one metric correlate with changes in another?
- Are there leading indicators that predict lagging metric changes?
- Do segment breakdowns reveal that an aggregate trend is driven by a specific cohort?

### 4. Generate the Review

#### Summary
2-3 sentences: overall product health, most notable changes, key callout.

#### Metric Scorecard
Table format for quick scanning:

| Metric | Current | Previous | Change | Target | Status |
|--------|---------|----------|--------|--------|--------|
| [Metric] | [Value] | [Value] | [+/- %] | [Target] | [On track / At risk / Miss] |

#### Trend Analysis
For each metric worth discussing:
- What happened and how significant is the change
- Why it likely happened (attribution based on known events, correlated metrics, segment analysis)
- Whether this is a one-time event or a sustained trend

#### Bright Spots
What is going well:
- Metrics beating targets
- Positive trends to sustain
- Segments or features showing strong performance

#### Areas of Concern
What needs attention:
- Metrics missing targets or trending negatively
- Early warning signals before they become problems
- Metrics where we lack visibility or understanding

#### Recommended Actions
Specific next steps based on the analysis:
- Investigations to run (dig deeper into a concerning trend)
- Experiments to launch (test hypotheses about what could improve a metric)
- Investments to make (double down on what is working)
- Alerts to set (monitor a metric more closely)

#### Context and Caveats
- Known data quality issues
- Events that affect comparability (outages, holidays, launches)
- Metrics we should be tracking but are not yet

### 5. Follow Up

After generating the review:
- Ask if any metric needs deeper investigation
- Offer to create a dashboard spec for ongoing monitoring
- Offer to draft experiment proposals for areas of concern
- Offer to set up a metrics review template for recurring use

## Product Metrics Hierarchy

### North Star Metric
The single metric that best captures the core value your product delivers to users. It should be:

- **Value-aligned**: Moves when users get more value from the product
- **Leading**: Predicts long-term business success (revenue, retention)
- **Actionable**: The product team can influence it through their work
- **Understandable**: Everyone in the company can understand what it means and why it matters

**Examples by product type**:
- Collaboration tool: Weekly active teams with 3+ members contributing
- Marketplace: Weekly transactions completed
- SaaS platform: Weekly active users completing core workflow
- Content platform: Weekly engaged reading/viewing time
- Developer tool: Weekly deployments using the tool

### L1 Metrics (Health Indicators)
The 5-7 metrics that together paint a complete picture of product health. These map to the key stages of the user lifecycle:

**Acquisition**: Are new users finding the product?
- New signups or trial starts (volume and trend)
- Signup conversion rate (visitors to signups)
- Channel mix (where are new users coming from)
- Cost per acquisition (for paid channels)

**Activation**: Are new users reaching the value moment?
- Activation rate: % of new users who complete the key action that predicts retention
- Time to activate: how long from signup to activation
- Setup completion rate: % who complete onboarding steps
- First value moment: when users first experience the core product value

**Engagement**: Are active users getting value?
- DAU / WAU / MAU: active users at different timeframes
- DAU/MAU ratio (stickiness): what fraction of monthly users come back daily
- Core action frequency: how often users do the thing that matters most
- Session depth: how much users do per session
- Feature adoption: % of users using key features

**Retention**: Are users coming back?
- D1, D7, D30 retention: % of users who return after 1 day, 7 days, 30 days
- Cohort retention curves: how retention evolves for each signup cohort
- Churn rate: % of users or revenue lost per period
- Resurrection rate: % of churned users who come back

**Monetization**: Is value translating to revenue?
- Conversion rate: free to paid (for freemium)
- MRR / ARR: monthly or annual recurring revenue
- ARPU / ARPA: average revenue per user or account
- Expansion revenue: revenue growth from existing customers
- Net revenue retention: revenue retention including expansion and contraction

**Satisfaction**: How do users feel about the product?
- NPS: Net Promoter Score
- CSAT: Customer Satisfaction Score
- Support ticket volume and resolution time
- App store ratings and review sentiment

### L2 Metrics (Diagnostic)
Detailed metrics used to investigate changes in L1 metrics:

- Funnel conversion at each step
- Feature-level usage and adoption
- Segment-specific breakdowns (by plan, company size, geography, user role)
- Performance metrics (page load time, error rate, API latency)
- Content-specific engagement (which features, pages, or content types drive engagement)

## Common Product Metrics

### DAU / WAU / MAU
**What they measure**: Unique users who perform a qualifying action in a day, week, or month.

**Key decisions**:
- What counts as "active"? A login? A page view? A core action? Define this carefully — different definitions tell different stories.
- Which timeframe matters most? DAU for daily-use products (messaging, email). WAU for weekly-use products (project management). MAU for less frequent products (tax software, travel booking).

**How to use them**:
- DAU/MAU ratio (stickiness): values above 0.5 indicate a daily habit. Below 0.2 suggests infrequent usage.
- Trend matters more than absolute number. Is active usage growing, flat, or declining?
- Segment by user type. Power users and casual users behave very differently.

### Retention
**What it measures**: Of users who started in period X, what % are still active in period Y?

**Common retention timeframes**:
- D1 (next day): Was the first experience good enough to come back?
- D7 (one week): Did the user establish a habit?
- D30 (one month): Is the user retained long-term?
- D90 (three months): Is this a durable user?

**How to use retention**:
- Plot retention curves by cohort. Look for: initial drop-off (activation problem), steady decline (engagement problem), or flattening (good — you have a stable retained base).
- Compare cohorts over time. Are newer cohorts retaining better than older ones? That means product improvements are working.
- Segment retention by activation behavior. Users who completed onboarding vs those who did not. Users who used feature X vs those who did not.

### Conversion
**What it measures**: % of users who move from one stage to the next.

**Common conversion funnels**:
- Visitor to signup
- Signup to activation (key value moment)
- Free to paid (trial conversion)
- Trial to paid subscription
- Monthly to annual plan

**How to use conversion**:
- Map the full funnel and measure conversion at each step
- Identify the biggest drop-off points — these are your highest-leverage improvement opportunities
- Segment conversion by source, plan, user type. Different segments convert very differently.
- Track conversion over time. Is it improving as you iterate on the experience?

### Activation
**What it measures**: % of new users who reach the moment where they first experience the product's core value.

**Defining activation**:
- Look at retained users vs churned users. What actions did retained users take that churned users did not?
- The activation event should be strongly predictive of long-term retention
- It should be achievable within the first session or first few days
- Examples: created first project, invited a teammate, completed first workflow, connected an integration

**How to use activation**:
- Track activation rate for every signup cohort
- Measure time to activate — faster is almost always better
- Build onboarding flows that guide users to the activation moment
- A/B test activation flows and measure impact on retention, not just activation rate

## Goal Setting Frameworks

### OKRs (Objectives and Key Results)

**Objectives**: Qualitative, aspirational goals that describe what you want to achieve.
- Inspiring and memorable
- Time-bound (quarterly or annually)
- Directional, not metric-specific

**Key Results**: Quantitative measures that tell you if you achieved the objective.
- Specific and measurable
- Time-bound with a clear target
- Outcome-based, not output-based
- 2-4 Key Results per Objective

**Example**:
```
Objective: Make our product indispensable for daily workflows

Key Results:
- Increase DAU/MAU ratio from 0.35 to 0.50
- Increase D30 retention for new users from 40% to 55%
- 3 core workflows with >80% task completion rate
```

### OKR Best Practices
- Set OKRs that are ambitious but achievable. 70% completion is the target for stretch OKRs.
- Key Results should measure outcomes (user behavior, business results), not outputs (features shipped, tasks completed).
- Do not have too many OKRs. 2-3 objectives with 2-4 KRs each is plenty.
- OKRs should be uncomfortable. If you are confident you will hit all of them, they are not ambitious enough.
- Review OKRs at mid-period. Adjust effort allocation if some KRs are clearly off track.
- Grade OKRs honestly at end of period. 0.0-0.3 = missed, 0.4-0.6 = progress, 0.7-1.0 = achieved.

### Setting Metric Targets
- **Baseline**: What is the current value? You need a reliable baseline before setting a target.
- **Benchmark**: What do comparable products achieve? Industry benchmarks provide context.
- **Trajectory**: What is the current trend? If the metric is already improving at 5% per month, a 6% target is not ambitious.
- **Effort**: How much investment are you putting behind this? Bigger bets warrant more ambitious targets.
- **Confidence**: How confident are you in hitting the target? Set a "commit" (high confidence) and a "stretch" (ambitious).

## Metric Review Cadences

### Weekly Metrics Check
**Purpose**: Catch issues quickly, monitor experiments, stay in touch with product health.
**Duration**: 15-30 minutes.
**Attendees**: Product manager, maybe engineering lead.

**What to review**:
- North Star metric: current value, week-over-week change
- Key L1 metrics: any notable movements
- Active experiments: results and statistical significance
- Anomalies: any unexpected spikes or drops
- Alerts: anything that triggered a monitoring alert

**Action**: If something looks off, investigate. Otherwise, note it and move on.

### Monthly Metrics Review
**Purpose**: Deeper analysis of trends, progress against goals, strategic implications.
**Duration**: 30-60 minutes.
**Attendees**: Product team, key stakeholders.

**What to review**:
- Full L1 metric scorecard with month-over-month trends
- Progress against quarterly OKR targets
- Cohort analysis: are newer cohorts performing better?
- Feature adoption: how are recent launches performing?
- Segment analysis: any divergence between user segments?

**Action**: Identify 1-3 areas to investigate or invest in. Update priorities if metrics reveal new information.

### Quarterly Business Review
**Purpose**: Strategic assessment of product performance, goal-setting for next quarter.
**Duration**: 60-90 minutes.
**Attendees**: Product, engineering, design, leadership.

**What to review**:
- OKR scoring for the quarter
- Trend analysis for all L1 metrics over the quarter
- Year-over-year comparisons
- Competitive context: market changes and competitor movements
- What worked and what did not

**Action**: Set OKRs for next quarter. Adjust product strategy based on what the data shows.

## Dashboard Design Principles

### Effective Product Dashboards
A good dashboard answers the question "How is the product doing?" at a glance.

**Principles**:

1. **Start with the question, not the data**. What decisions does this dashboard support? Design backwards from the decision.

2. **Hierarchy of information**. The most important metric should be the most visually prominent. North Star at the top, L1 metrics next, L2 metrics available on drill-down.

3. **Context over numbers**. A number without context is meaningless. Always show: current value, comparison (previous period, target, benchmark), trend direction.

4. **Fewer metrics, more insight**. A dashboard with 50 metrics helps no one. Focus on 5-10 that matter. Put everything else in a detailed report.

5. **Consistent time periods**. Use the same time period for all metrics on a dashboard. Mixing daily and monthly metrics creates confusion.

6. **Visual status indicators**. Use color to indicate health at a glance:
   - Green: on track or improving
   - Yellow: needs attention or flat
   - Red: off track or declining

7. **Actionability**. Every metric on the dashboard should be something the team can influence. If you cannot act on it, it does not belong on the product dashboard.

### Dashboard Layout

**Top row**: North Star metric with trend line and target.

**Second row**: L1 metrics scorecard — current value, change, target, status for each key metric.

**Third row**: Key funnels or conversion metrics — visual funnel showing drop-off at each stage.

**Fourth row**: Recent experiments and launches — active A/B tests, recent feature launches with early metrics.

**Bottom / drill-down**: L2 metrics, segment breakdowns, and detailed time series for investigation.

### Dashboard Anti-Patterns
- **Vanity metrics**: Metrics that always go up but do not indicate health (total signups ever, total page views)
- **Too many metrics**: Dashboards that require scrolling to see. If it does not fit on one screen, cut metrics.
- **No comparison**: Raw numbers without context (current value with no previous period or target)
- **Stale dashboards**: Metrics that have not been updated or reviewed in months
- **Output dashboards**: Measuring team activity (tickets closed, PRs merged) instead of user and business outcomes
- **One dashboard for all audiences**: Executives, PMs, and engineers need different views. One size does not fit all.

### Alerting
Set alerts for metrics that require immediate attention:

- **Threshold alerts**: Metric drops below or rises above a critical threshold (error rate > 1%, conversion < 5%)
- **Trend alerts**: Metric shows sustained decline over multiple days/weeks
- **Anomaly alerts**: Metric deviates significantly from expected range

**Alert hygiene**:
- Every alert should be actionable. If you cannot do anything about it, do not alert on it.
- Review and tune alerts regularly. Too many false positives and people ignore all alerts.
- Define an owner for each alert. Who responds when it fires?
- Set appropriate severity levels. Not everything is P0.

## Output Format

Use tables for the scorecard. Use clear status indicators. Keep the summary tight — the reader should get the essential story in 30 seconds.

## Tips

- Start with the "so what" — what is the most important thing in this metrics review? Lead with that.
- Absolute numbers without context are useless. Always show comparisons (vs previous period, vs target, vs benchmark).
- Be careful about attribution. Correlation is not causation. If a metric moved, acknowledge uncertainty about why.
- Segment analysis often reveals that an aggregate metric masks important differences. A flat overall number might hide one segment growing and another shrinking.
- Not all metric movements matter. Small fluctuations are noise. Focus attention on meaningful changes.
- If a metric is missing its target, do not just report the miss — recommend what to do about it.
- Metrics reviews should drive decisions. If the review does not lead to at least one action, it was not useful.
