How to Benchmark Manager Effectiveness with Passive ONA in 2025 (Using Google Workspace & Slack Data)
Introduction
Manager effectiveness drives 80% of employee experience, making it the single most critical factor in organizational success (Worklytics). Yet most HR teams still rely on annual surveys and subjective feedback to measure manager performance—a reactive approach that misses real-time warning signs and coaching opportunities.
Passive Organizational Network Analysis (ONA) changes this equation entirely. By analyzing metadata from Google Workspace and Slack, HR analytics teams can now build comprehensive manager scorecards without surveys, capturing meeting load, response times, and cross-team collaboration patterns in real-time (Worklytics). This approach reveals which managers are overwhelmed, which teams are isolated, and where coaching interventions will have the highest impact.
This guide walks you through a repeatable workflow for transforming raw collaboration data into actionable manager insights. You'll learn how to extract anonymized data feeds, map key effectiveness metrics in Power BI, and benchmark results against 2024 industry standards to identify at-risk managers before problems escalate.
Why Passive ONA Outperforms Traditional Manager Assessment
Traditional manager effectiveness measurement relies heavily on periodic surveys, 360-degree feedback, and performance reviews—all of which suffer from recency bias, survey fatigue, and delayed insights (Visier). By the time these assessments reveal problems, team productivity has already suffered.
Passive ONA techniques analyze IT metadata to examine the volume, frequency, and type of interactions managers have with their teams, outputting objective scores for manager proximity and engagement (Worklytics). This approach provides several advantages:
• Real-time visibility: Spot collaboration breakdowns as they happen, not months later
• Objective measurement: Remove subjective bias from manager assessment
•
Privacy protection: Analyze patterns without accessing message content (
Worklytics)
•
Historical trending: Track manager effectiveness changes over time with up to 3 years of historical data (
Worklytics)
Setting Up Your Passive ONA Data Pipeline
Step 1: Configure Data Connectors
Worklytics provides pre-built connectors for over 25 collaboration platforms, making data extraction straightforward (Worklytics). For manager effectiveness analysis, focus on these core data sources:
Google Workspace Integration

Worklytics)
• Gmail metadata shows response times and communication volume
• Drive activity indicates collaboration on shared documents
Slack Integration
• Message frequency and response patterns across channels (
Worklytics)
• Cross-team communication reach and network centrality
• After-hours activity and availability patterns
Step 2: Ensure Privacy and Compliance
Before extracting any data, establish proper privacy safeguards. Worklytics automatically anonymizes data at the source, ensuring compliance with GDPR, CCPA, and other data protection standards (Worklytics). Key privacy measures include:
• Pseudonymization of employee identifiers
• Aggregation of individual metrics to team levels
• Exclusion of message content from analysis
• Role-based access controls for sensitive data
Step 3: Historical Data Extraction
Worklytics can generate ONA graphs analyzing collaboration networks going back up to 3 years into historical records within corporate tools (Worklytics). This historical depth enables:
• Baseline establishment for manager effectiveness metrics
• Trend analysis to identify improving or declining performance
• Seasonal pattern recognition (e.g., Q4 meeting overload)
• Impact assessment of organizational changes
