Resource Management

Purpose

資源管理系統，提供負載熱圖與人員容量追蹤，協助主管進行資源分配決策。讓主管能即時掌握團隊成員的工作負載狀況，及早發現超載或閒置問題，優化資源分配。

Requirements

• WHEN 主管查詢負載熱圖 API
• THEN 該人員的 load_level 為 overloaded

Scenario: 查詢特定週的負載

• GIVEN 主管需要查看非當週的負載
• WHEN 主管以 week_start 參數查詢負載熱圖 API
• THEN 系統回傳該週的負載資料

• GIVEN 負載資料已被計算並快取
• WHEN 相同查詢在 1 小時內再次發生
• THEN 系統從 Redis 快取回傳結果

Requirement: Capacity Planning

Scenario: 設定人員預設容量

• GIVEN 管理者需要設定人員的週工時上限
• WHEN 管理者更新使用者的 capacity 值
• THEN 系統儲存新的容量設定
• AND 後續負載計算使用新容量值

Scenario: 容量為零處理

• GIVEN 使用者的容量設為 0
• WHEN 系統計算該使用者的負載
• THEN load_percentage 顯示為 null
• AND load_level 顯示為 unavailable

Scenario: 容量更新 API

• GIVEN 管理者需要更新團隊成員的容量
• WHEN 管理者呼叫 PUT /api/users/{user_id}/capacity 並提供新容量值
• THEN 系統驗證容量值在有效範圍內 (0-168 小時)
• AND 更新使用者的 capacity 欄位
• AND 記錄變更至稽核日誌

Scenario: 容量更新權限控制

• GIVEN 一般使用者嘗試更新他人容量
• WHEN 使用者呼叫 PUT /api/users/{other_id}/capacity
• THEN 系統拒絕請求並回傳 403 Forbidden

Requirement: Multi-Project Health Dashboard

系統 SHALL 提供多專案健康看板，讓主管一覽所有專案狀態。

Scenario: 專案健康總覽

• GIVEN 主管負責多個專案
• WHEN 主管開啟健康看板
• THEN 顯示所有專案的進度、風險指標、延遲任務數
• AND 可依風險程度排序

Scenario: 專案延遲警示

• GIVEN 專案有任務超過截止日期
• WHEN 主管查看健康看板
• THEN 該專案標示為延遲狀態
• AND 顯示延遲任務數量與影響

Scenario: 專案健康 API

• GIVEN 後端系統運行中
• WHEN 客戶端請求 GET /api/projects/health
• THEN 系統回傳所有可存取專案的健康數據
• AND 包含 total_tasks, completed_tasks, overdue_tasks, blocked_tasks, risk_score

Scenario: 單一專案健康詳情

• GIVEN 主管需要查看特定專案詳情
• WHEN 客戶端請求 GET /api/projects/{id}/health
• THEN 系統回傳該專案的詳細健康數據
• AND 包含任務分類統計與風險評估

Requirement: Team Workload Distribution

系統 SHALL 提供團隊工作分配查詢功能。

Scenario: 部門負載總覽

• GIVEN 主管需要了解部門整體負載
• WHEN 主管以 department_id 參數查詢負載熱圖 API
• THEN 僅顯示該部門成員的負載狀況

Scenario: 使用者負載詳情

• GIVEN 主管需要了解某人的詳細任務分配
• WHEN 主管查詢使用者負載詳情 API
• THEN 回傳該週指派給該使用者的所有任務
• AND 包含每個任務的 original_estimate 與 due_date

Requirement: Workload Data Access Control

系統 SHALL 限制負載資料的存取權限。

Scenario: 系統管理員查看所有人

• GIVEN 登入者為 super_admin
• WHEN 查詢負載熱圖 API
• THEN 可查看所有使用者的負載資料

Scenario: 一般使用者查看自己

• GIVEN 登入者為一般使用者
• WHEN 查詢負載熱圖 API 未指定 user_ids
• THEN 僅回傳自己的負載資料

Scenario: 跨部門存取拒絕

• GIVEN 登入者非系統管理員
• WHEN 查詢其他部門使用者的負載
• THEN 系統拒絕存取並回傳 403 Forbidden

Requirement: Workload Heatmap UI

The system SHALL provide a visual workload heatmap interface for managers.

Scenario: View workload heatmap

• GIVEN user is logged in as manager or admin
• WHEN user navigates to /workload page
• THEN system displays a heatmap showing all accessible users' workload
• AND each user cell is color-coded by load level (green/yellow/red)

Scenario: Navigate between weeks

• GIVEN user is viewing the workload page
• WHEN user clicks previous/next week buttons
• THEN the heatmap updates to show that week's workload data

Scenario: View user workload details

• GIVEN user is viewing the workload heatmap
• WHEN user clicks on a specific user's cell
• THEN a modal/drawer opens showing that user's task breakdown
• AND tasks show title, project, time estimate, and due date

Scenario: Filter by department

• GIVEN user is a system admin
• WHEN user selects a department from the filter
• THEN the heatmap shows only users from that department

Requirement: Manager Workload Visibility

The system SHALL allow department managers to view workload data for all members within their department.

Scenario: Manager views department member workload

• WHEN a department manager requests workload data for a user in their department
• THEN system returns the workload data for that user

Scenario: Manager denied access to other department workload

• WHEN a department manager requests workload data for a user in a different department
• THEN system returns 403 Forbidden error

Scenario: Regular user cannot view others' workload

• WHEN a non-manager user requests workload data for another user
• THEN system returns 403 Forbidden error

Requirement: Cross-Department Project Membership

The system SHALL support explicit project membership to enable cross-department collaboration.

Scenario: Add cross-department member to project

• WHEN project owner adds a user from another department as project member
• THEN user gains access to the project regardless of department

Scenario: Project member accesses cross-department project

• WHEN a project member from another department accesses project resources
• THEN system grants access based on project membership

Scenario: Non-member denied access despite same department

• WHEN a user not in project membership list attempts to access confidential project
• THEN system denies access unless user is in the project's department

Calculation Rules

• 負載百分比 = (allocated_hours / capacity_hours) × 100
• 風險評分 = f(overdue_tasks, blocked_tasks, timeline_remaining)
• 快取計算結果於 Redis，每小時更新或任務變更時即時更新
