Context and Overview

Company uses 7 different systems: ATS (recruiting), HRIS (HR records), LMS (training), payroll, scheduling, POS (for retail), and survey tool. Data in each system is disconnected. Recruiting data doesn't flow to HRIS. Training data doesn't connect to performance data. Survey data is siloed in separate tool. Result: Manual data entry, duplicate data, conflicting data, slow reporting.

The Cost of Disconnected Systems

Manual entry: HR imports hired candidates from ATS to HRIS manually (error-prone, slow) Duplicate data: Candidate in ATS, then in HRIS, then in payroll (if updates in one place, others are stale) Reporting friction: Recruiting report pulls from ATS; retention report pulls from HRIS; they don't align Time cost: HR spends 30% of time on data management (pulling, aligning, reconciling) instead of strategic work Decision delay: Report needed takes 2 weeks because data must be manually compiled

Integration Strategy

API-driven architecture: Systems talk to each other via APIs (application programming interfaces) Example: Candidate hired in ATS → automatically creates HRIS record → sends offer letter → initiates training module → triggers first payroll entry Single source of truth: One system as master (e.g., HRIS is master for employee data; all other systems reference it) Data flow: Define how data flows (ATS → HRIS → Payroll → LMS → Survey) Automation: Replace manual entry with automated data sync

Implementation Steps

Step 1: Audit systems and data flows (what data is where, how does it move) Step 2: Map desired integrations (ATS → HRIS, HRIS → Payroll, etc.) Step 3: Prioritize (integrate highest-impact flows first) Step 4: Select integration platform (Zapier, MuleSoft, custom APIs) Step 5: Build integrations (can be simple like Zapier, or complex like custom APIs) Step 6: Test thoroughly (ensure data accuracy) Step 7: Monitor (ensure integrations run smoothly)

ROI of Integration

Time saved: 30% of HR time spent on data management → 1 FTE saved (annual cost $60,000) Accuracy improved: Duplicate data eliminated; data quality improves Speed improved: Reports generate automatically instead of manual compilation (days → hours) Cost: Integration platform ($200-500/month) + IT implementation ($10,000-20,000 one-time) Payback: <1 year through time savings
