Seven Best Practices for Implementing Microsoft RPA

Based on my experience implementing Microsoft RPA solutions across multiple industries, I’ve identified seven best practices that consistently drive successful outcomes:

1. Begin with Process Mining and Assessment

Before building automation, use Process Advisor to analyze existing workflows. In my experience, this step often reveals unexpected insights:

Case in Point: At a resources company, Process Advisor analysis revealed that what was documented as a 12-step approval process actually contained 27 unique paths with numerous undocumented decision points. This discovery completely changed our automation approach.

Key Actions:
– Run Process Advisor on actual process executions, not just documented procedures
– Identify variations and exceptions before designing automation
– Quantify the current state with metrics to establish a baseline
– Identify process improvements that should occur before automation

2. Leverage the Microsoft Integration Advantage

One of Power Platform’s greatest strengths is its native integration with Microsoft’s ecosystem:

Implementation Example: For a financial services client, we connected Power Automate directly to SharePoint document libraries, Teams approval workflows, and Outlook notifications. This eliminated dozens of integration points that would have been required with third-party RPA tools.

Key Actions:
– Inventory all Microsoft services currently used in processes
– Prioritize native connectors over custom integrations
– Use dataverse as the central data repository when possible
– Leverage Microsoft 365 security models for authentication

3. Combine UI and API Automation Strategically

The most successful Microsoft RPA implementations blend UI automation (Desktop Flows) with API integration (Cloud Flows):

Strategy Example: When automating supplier onboarding, we used API connectors for modern systems (Microsoft Dynamics) while implementing UI automation for legacy vendor management systems. This hybrid approach maximized reliability while still achieving end-to-end automation.

Key Actions:
– Map each system interaction as either API-eligible or requiring UI automation
– Minimize desktop flow dependencies when possible
– Design cloud flows to handle orchestration and business logic
– Create resilient error handling between UI and API components

4. Implement Robust Error Handling

RPA failure points often occur at system boundaries or when encountering unexpected data variations:

Real-world Application: For a healthcare provider's billing automation, we implemented a three-tier error handling approach: automated retry logic for transient errors, human-in-the-loop exception handling for complex cases, and systematic logging for continuous improvement.

Key Actions:
– Categorize potential errors by type (system, data, business rule, etc.)
– Create appropriate handling strategies for each category
– Implement comprehensive logging throughout the automation
– Design alerts and notifications for critical failures

5. Build Governance from Day One

Sustainable RPA programs require strong governance frameworks:

Governance Framework: For an energy sector client, we established a Center of Excellence model that included standard development practices, centralized monitoring, and a formal intake process for automation candidates. This structured approach enabled scaling from 5 to 50+ automations while maintaining quality.

Key Actions:
– Establish development standards and patterns
– Implement environment management (dev, test, prod)
– Create monitoring dashboards for automation health
– Develop documentation requirements for all automations

6. Enhance RPA with AI Capabilities

Microsoft’s AI Builder provides opportunities to make RPA more intelligent:

AI Enhancement Example: By integrating AI Builder's sentiment analysis with a customer service automation, we were able to escalate negative interactions to human agents while allowing the bot to handle routine inquiries. This improved customer satisfaction by 18%.

Key Actions:
– Identify decision points that could benefit from AI enhancement
– Use pre-built AI models for common needs (text recognition, classification)
– Build custom AI models for organization-specific requirements
– Implement confidence scoring to determine when human intervention is needed

7. Measure Business Impact, Not Just Technical Metrics

Successful RPA programs track business outcomes, not just automation statistics:

Measurement Approach: For a manufacturing client, we created a balanced scorecard that tracked not only automation runtime and success rates but also business metrics like order processing times, exception rates, and cost per transaction. This approach helped sustain executive support by demonstrating tangible business value.

Key Actions:
– Define business metrics before implementation begins
– Create dashboards that relate technical performance to business outcomes
– Implement before/after measurement of process efficiency
– Calculate and report ROI regularly

Common Implementation Challenges and Solutions

Despite careful planning, Microsoft RPA implementations often face predictable challenges:

Legacy System Compatibility

Challenge: Older applications may have inconsistent UIs or lack accessibility identifiers needed for stable automation.

Solution: Implement application-specific workarounds such as:
– Image-based recognition as a fallback mechanism
– Consistent navigation patterns that don’t rely on dynamic elements
– Scheduled maintenance windows to update selectors after system changes

Change Management Resistance

Challenge: Staff may resist automation due to job security concerns or distrust of technology.

Solution: Address human factors directly:
– Involve process experts in automation design
– Focus communication on augmentation rather than replacement
– Create reskilling opportunities for affected staff
– Celebrate and reward contributions to automation success

Scaling Beyond Initial Success

Challenge: Moving from pilot success to enterprise implementation often encounters resource constraints and governance challenges.

Solution: Build for scale from the beginning:
– Establish a centralized repository of reusable components
– Implement approval workflows for production deployment
– Create automation templates for common use cases
– Develop metrics that demonstrate enterprise impact
