Task Management System - Technical Specification

Executive Summary​

The Task Management System will provide industry-specific, configurable workflow automation for trucking and service/repair operations. The system combines standardized task templates with custom organizational workflows, enabling automated task assignment, progress tracking, and compliance management.

Mental Model Overview​

Organization → Task Templates → Rule Engine → Task Instances → Progress Tracking
     ↓              ↓              ↓              ↓              ↓
   Custom        Standard       Auto/Manual    Assigned to    Real-time
   Rules         Industry       Assignment     Driver/Job     Updates

1. Task States (Industry Standard)​

Based on field operations and workflow management best practices:

Primary States​

  • PENDING - Task assigned but not started
  • IN_PROGRESS - Task actively being worked on
  • COMPLETED - Task successfully finished
  • SKIPPED - Task bypassed with reason (requires approval)
  • FAILED - Task attempted but unsuccessful
  • BLOCKED - Task cannot proceed due to dependencies
  • CANCELLED - Task no longer required

Meta States​

  • OVERDUE - Past deadline (can combine with other states)
  • PRIORITY - Urgent task (can combine with other states)

2. Data Architecture Options​

Structure: Tasks stored within leg/job documents

Pros:

  • ✅ Single database query for load + tasks
  • ✅ Atomic updates (load and tasks together)
  • ✅ Simpler data consistency
  • ✅ Better performance for mobile apps
  • ✅ Natural document lifecycle management

Cons:

  • ❌ Document size limits with many tasks
  • ❌ More complex task querying across loads
  • ❌ Harder to build task analytics dashboard

Option B: Separate Task Collection​

Structure: Tasks as independent documents with load references

Pros:

  • ✅ Unlimited tasks per load
  • ✅ Easy cross-load task analytics
  • ✅ Better for complex task relationships
  • ✅ More flexible querying capabilities

Cons:

  • ❌ Multiple database queries required
  • ❌ More complex data consistency
  • ❌ Potential orphaned tasks
  • ❌ Additional network overhead for mobile

Option C: Hybrid Approach (Most Flexible)​

Structure: Critical tasks embedded, detailed tasks separate

Implementation:

  • Current task + next 2-3 tasks embedded in load
  • All tasks stored in separate collection for full history
  • Sync mechanism between embedded and full task data

3. Task Template vs Instance Handling​

Option 1: Template Inheritance Model​

TaskTemplate {
  id: "pre-delivery-inspection-v2",
  name: "Pre-delivery Inspection",
  industry: "trucking",
  steps: [...],
  rules: {...}
}

TaskInstance {
  templateId: "pre-delivery-inspection-v2",
  loadId: "...",
  customizations: {...},
  progress: {...}
}
TaskInstance {
  id: "...",
  loadId: "...",
  templateSnapshot: {
    // Full template copied at creation
    name: "Pre-delivery Inspection",
    steps: [...],
    version: "2.1"
  },
  progress: {...},
  customizations: {...}
}

Option 3: Reference Model​

TaskInstance {
  templateId: "pre-delivery-inspection",
  templateVersion: "2.1",
  progress: {...},
  overrides: {...}
}

4. Proposed Data Schema​

Task Template Schema​

{
  _id: ObjectId,
  name: "Pre-delivery Inspection",
  description: "Complete vehicle inspection before delivery",
  industry: "trucking", // "trucking" | "service_repair" | "general"
  category: "safety", // "safety" | "documentation" | "maintenance" | "delivery"

  // Template Definition
  steps: [
    {
      id: "check_tires",
      title: "Check tire pressure and condition",
      type: "checkbox", // "checkbox" | "photo" | "signature" | "text" | "selection"
      required: true,
      estimatedMinutes: 5,
      instructions: "Verify all tires are properly inflated...",
      validationRules: {...}
    }
  ],

  // Assignment Rules
  assignmentRules: {
    triggers: ["status_change:in_transit", "load_type:hazmat"],
    conditions: {
      loadWeight: { min: 10000 }, // Conditional assignment
      equipmentType: ["flatbed", "refrigerated"]
    },
    timing: {
      relativeToStatus: "in_transit",
      offsetHours: -2 // 2 hours before status change
    }
  },

  // Configuration
  isActive: true,
  organizationId: ObjectId, // null for system templates
  createdBy: ObjectId,
  version: "2.1",

  // Integration
  documentsRequired: true, // Links to documents tab
  statusUpdateTrigger: "delivered", // Auto-update load status when complete

  // Timing
  estimatedDuration: 30, // minutes
  deadline: {
    type: "relative", // "relative" | "absolute"
    value: 24, // hours from assignment
    required: true
  },

  // Notifications
  reminders: [
    { beforeDeadlineHours: 4, message: "Pre-delivery inspection due in 4 hours" },
    { beforeDeadlineHours: 1, message: "URGENT: Pre-delivery inspection due in 1 hour" }
  ]
}

Task Instance Schema​

{
  _id: ObjectId,
  loadId: ObjectId,
  templateSnapshot: {...}, // Full template at time of creation

  // Current State
  status: "IN_PROGRESS",
  currentStepIndex: 2,

  // Assignment
  assignedTo: ObjectId, // Driver ID
  assignedAt: Date,
  dueDate: Date,

  // Progress Tracking
  startedAt: Date,
  completedAt: Date,
  stepProgress: [
    {
      stepId: "check_tires",
      status: "COMPLETED",
      completedAt: Date,
      completedBy: ObjectId,
      data: {
        photos: ["url1", "url2"],
        notes: "All tires in good condition",
        checkboxValue: true
      }
    }
  ],

  // Metadata
  completionNotes: "Inspection completed successfully",
  failureReason: null,
  skipReason: null,
  approvedBy: ObjectId, // For skipped/failed tasks

  // Integration Data
  documentsGenerated: ["doc_id_1", "doc_id_2"],
  statusUpdateTriggered: false,

  // Timing
  estimatedCompletionTime: Date,
  actualDuration: 25, // minutes

  // Audit Trail
  createdAt: Date,
  updatedAt: Date,
  history: [
    {
      action: "status_change",
      from: "PENDING",
      to: "IN_PROGRESS",
      timestamp: Date,
      userId: ObjectId
    }
  ]
}

5. Rule Engine Architecture​

Trigger Types​

  1. Status Changes: Load status transitions
  2. Time-based: Scheduled or deadline-driven
  3. Location-based: Geofence entries/exits
  4. Manual: Dispatcher/driver initiated
  5. Conditional: Based on load properties

Example Rules​

{
  name: "Hazmat Safety Inspection",
  trigger: {
    type: "status_change",
    from: "assigned",
    to: "in_transit"
  },
  conditions: {
    "load.hazmat": true,
    "load.weight": { "$gte": 5000 }
  },
  actions: [
    {
      type: "create_task",
      templateId: "hazmat-safety-inspection",
      assignTo: "driver",
      dueInHours: 2
    }
  ]
}
