From Lean to AI: The Evolution of Process Excellence in Health Systems

Healthcare systems are no strangers to the concept of process improvement. For years, methodologies like Lean and Six Sigma have guided organizations in eliminating inefficiencies, reducing costs, and enhancing patient care. But the rapid emergence of artificial intelligence (AI) and automation technologies is challenging us to think beyond traditional paradigms. AI isn’t just a tool for incremental improvement; it represents a seismic shift in how we approach operational excellence. It’s time for health systems to take the next step in their transformation journey by establishing an AI Center of Excellence (COE) — the new frontier in process optimization.

The Legacy of Lean

Lean methodologies have long focused on identifying value-added and non-value-added tasks within workflows, with the goal of redesigning processes to eliminate waste. It’s a powerful framework that has yielded remarkable results in healthcare, from streamlining patient flow to reducing waiting times. However, Lean often relies on manual observation and incremental adjustments, which, while effective, have their limitations in today’s fast-paced, data-driven environment.

AI as the New Lean

Artificial intelligence and automation take the principles of Lean to the next level. Rather than solely redesigning workflows to eliminate waste, AI enables us to:

• Identify Automation Opportunities: Pinpoint tasks within processes that are ripe for automation, such as repetitive administrative work or data entry.
• Enhance Value-Added Activities: Use AI to improve the efficiency and accuracy of critical activities, such as clinical decision support or patient scheduling.
• Leverage Data Insights: Unlike Lean, which often relies on human input for process mapping, AI can analyze vast amounts of data to uncover inefficiencies and predict bottlenecks in real-time. Additionally, process mining tools can “crawl” through systems to understand how users are actually interacting with them. These tools provide insights into the real processes being performed, often uncovering discrepancies between documented workflows and actual practices. Traditional Lean methods, such as observing the GEMBA or interviewing frontline workers, offer valuable insights but can be limited to snapshots or incomplete recollections. Process mining automates process flow mapping, offering a comprehensive and accurate view of the entire workflow.
• Scale Improvements: Deploy AI solutions at scale, ensuring consistent application across departments and facilities.

The Role of an AI Center of Excellence (COE)

An AI COE serves as the central hub for driving AI adoption and governance within a health system. Its purpose is multifaceted:

1. Governance and Strategy: The COE establishes guidelines for selecting, implementing, and managing AI technologies, ensuring alignment with organizational goals and compliance with regulations. This includes addressing critical challenges such as patient data privacy and the integration of AI into legacy systems. By setting clear protocols for data security and interoperability, the COE ensures that new AI solutions enhance operations without compromising sensitive information or disrupting existing workflows.
2. Use Case Prioritization: It identifies the highest-impact AI applications, balancing potential ROI with considerations of patient safety and legal risk.
3. Validation and Monitoring: The COE rigorously tests AI models, such as large language models (LLMs), for accuracy and reliability, and audits AI agents to prevent errors or hallucinations.
4. Education and Enablement: Acting as an AI coach, the COE trains frontline managers and staff on how to incorporate AI into their roles, fostering a culture of innovation and efficiency.

The Future of Process Improvement

The AI COE is not a replacement for Lean principles; it’s their evolution. Imagine using tools like ChatGPT as a lean practitioner—an AI assistant trained specifically in Lean methodologies or healthcare regulations. This AI agent could analyze uploaded data, such as stakeholder interview transcriptions, process flow maps, and operational metrics, to identify root causes of inefficiencies. Unlike traditional methods that rely on human interpretation alone, AI could provide objective insights and uncover patterns across datasets.

During kaizen events, AI agents could act as virtual team members, facilitating brainstorming sessions and offering evidence-based suggestions for future state solutions. For example, an AI agent trained in healthcare compliance could flag regulatory risks in proposed workflows or identify opportunities to streamline patient documentation. The combination of human expertise and AI collaboration could supercharge problem-solving efforts, making kaizen events more dynamic and impactful.

Think about a health system struggling with inefficiencies in patient scheduling. Traditionally, Lean might involve observing the scheduling process and interviewing staff to identify bottlenecks and delays. While valuable, this approach is often limited to a snapshot in time and dependent on human recollection. Integrating AI tools like process mining can change the game. These tools analyze system logs to uncover hidden patterns and inefficiencies, offering actionable insights that traditional Lean methods might miss. This combination of Lean and AI empowers health systems to redesign workflows with precision, improving both efficiency and patient experience. By combining Lean’s focus on value with AI’s capabilities, health systems can:

• Eliminate Non-Value-Added Tasks Entirely: Automate processes like appointment reminders, billing, or supply chain tracking.
• Enhance Human Decision-Making: Equip clinicians and administrators with AI tools that deliver real-time insights, improving care quality and operational decisions.
• Optimize Resources: Free up staff to focus on higher-value tasks, such as patient interaction, while AI handles the repetitive and mundane.

Why Now?

The healthcare industry is at a tipping point. Workforce shortages, rising costs, and increasing demands for quality care require innovative solutions. For example, the American Hospital Association reports that U.S. hospitals collectively face billions in uncompensated care annually, while a Deloitte study highlights that nearly 90% of healthcare executives believe AI could reduce operational costs significantly within the next five years. AI allows health systems to address these challenges head-on, but successful adoption requires a structured approach. That’s where the AI COE comes in, providing the governance, strategy, and expertise needed to integrate AI effectively and responsibly.
