Parallel Approval Workflows

Overview

The parallel approval feature enables concurrent reviews where multiple approvers can evaluate items simultaneously rather than sequentially. This dramatically reduces approval cycle times for time-sensitive operations.

Key Features

1. Concurrent Reviews

• Multiple approvers can review the same item at the same time
• No waiting for sequential approval chains
• Ideal for cross-functional reviews (e.g., Finance + Operations + Compliance)

2. Flexible Approval Modes

All Approvers Mode

• Requires: All assigned approvers must approve
• Use Case: High-stakes decisions requiring unanimous consent
• Example: Major contract approvals, large invoices

Any Approver Mode

• Requires: At least one approver must approve
• Use Case: Quick approvals where any expert can validate
• Example: Routine expense reports, standard timesheets

Majority Mode

• Requires: More than half of approvers must approve
• Use Case: Balanced decision-making with consensus
• Example: Policy changes, hiring decisions

3. Required vs Optional Approvers

• Mark specific approvers as Required - their approval is mandatory
• Optional approvers contribute to the approval mode calculation
• Example: Finance Manager (Required) + 2 Operations Managers (Optional, Majority mode)

4. Real-Time Progress Tracking

• Live visibility into approval status
• See who has approved/rejected/pending
• Progress bars and metrics
• Individual approver comments

Implementation

Data Structure

interface ApprovalStep {
  isParallel: boolean
  parallelApprovalMode: 'all' | 'any' | 'majority'
  parallelApprovals: ParallelApproval[]
}

interface ParallelApproval {
  approverId: string
  approverName: string
  approverRole: string
  status: 'pending' | 'approved' | 'rejected'
  isRequired: boolean
  comments?: string
}

Creating a Parallel Approval Step

1. Navigate to Settings → Workflow Templates
2. Create or edit a template
3. Edit an approval step
4. Toggle "Enable Parallel Approvals"
5. Select approval mode (All/Any/Majority)
6. Add approvers with their roles and mark required ones
7. Save the template

Using the Parallel Approval Demo

1. Go to Settings → Parallel Approvals in the navigation
2. Create a test workflow using a template with parallel steps
3. Simulate different approvers using the user selector
4. Test approval/rejection flows
5. Observe real-time progress updates

Business Benefits

Time Savings

• Sequential: 3 approvers × 24 hours = 72 hours

• Reduction: 67% faster approval cycle

Risk Management

• Required approvers ensure critical reviews happen
• Majority mode balances speed with consensus
• Full audit trail of all decisions

Flexibility

• Different modes for different risk levels
• Mix required and optional approvers
• Adapt workflows to organizational needs

Technical Details

Approval Logic

All Mode:

approved = requiredApprovals.all(approved) && allApprovals.all(approved)

Any Mode:

approved = requiredApprovals.all(approved) && allApprovals.any(approved)

Majority Mode:

approved = requiredApprovals.all(approved) && (approvedCount > totalCount / 2)

State Management

• Workflows stored in IndexedDB via useApprovalWorkflow hook
• Templates managed via useApprovalWorkflowTemplates hook
• Real-time updates through functional state updates

Components
