Lean Six Sigma: Looking Back at 2022 and Ahead to 2023
Every December invites reflection -- and for Lean Six Sigma practitioners, 2022 offered a great deal to reflect on. The year saw the methodology pushed into new sectors, tested against new challenges, and connected to new technologies in ways that would have seemed ambitious just a few years ago. As 2023 approaches, the question is not whether Lean Six Sigma remains relevant but how organisations can position themselves to capture that relevance in the year ahead.
Healthcare: The Year LSS Moved from Optional to Expected
The most significant trend in LSS adoption during 2022 was the continued acceleration in healthcare. The pandemic exposed process fragility at scale -- supply chain breakdowns, capacity mismatches, discharge bottlenecks, and scheduling failures that overwhelmed systems under stress. Health authorities across Canada and internationally responded by treating Lean and Six Sigma not as improvement projects but as operational infrastructure.
What changed in 2022 was the level of seniority behind that commitment. Chief Medical Officers and Chief Nursing Officers began appearing as sponsors of improvement programmes in ways that had previously been the domain of quality departments. Executive ownership is the single most reliable predictor of sustained improvement gains, and its emergence in healthcare was one of 2022's most consequential shifts.
Government Efficiency Mandates and the LSS Response
Across federal, provincial, and municipal governments in Canada, 2022 brought renewed pressure on efficiency. Budget constraints, post-pandemic service backlogs, and public expectations of digital-era responsiveness combined to make the status quo politically untenable in many departments. Lean Six Sigma, with its emphasis on waste elimination and measurable outcomes, became a preferred methodology for government efficiency initiatives -- valued precisely because it produces documented evidence of improvement rather than assertions.
The challenge in government settings remains the same as it has always been: sustaining gains through election cycles and leadership transitions. Programmes that become embedded in standard operating procedures and supported by trained internal practitioners fare far better than those that depend on a single champion.
LSS and Digital Transformation: A Partnership Maturing
One of the more significant evolutions in 2022 was the maturing integration of LSS with digital transformation programmes. The two had long been treated as separate workstreams -- process improvement here, technology implementation there -- with coordination happening only when conflicts arose. In 2022, leading organisations began treating them as genuinely interdependent: LSS to understand and stabilise the current process before automating it, and digital tools to extend the reach and speed of improvement initiatives.
This integration matters because automating a broken process simply produces broken outcomes faster. The LSS principle of understanding current-state process capability before designing future-state solutions is exactly the discipline that prevents costly technology implementations from replicating existing waste at scale.
Knowledge Work and Persistent Challenges
Growing interest in applying LSS to knowledge work -- professional services, legal, finance, research -- was one of the year's defining trends. Knowledge work defies easy measurement, and practitioners who adapted their tools made meaningful progress; those who applied manufacturing-era LSS without adaptation found limited traction. Three persistent challenges continued to limit LSS impact more broadly:
Sustaining gains after the project closes: improvement initiatives deliver results, but without structural embedding in standard work and ongoing measurement, regression is the norm within twelve to eighteen months.
Leadership commitment that does not translate to behaviour: executives who sponsor LSS programmes but do not visibly change how they prioritise, resource, and reward improvement work send a signal that undermines the whole effort.
Measuring ROI in service settings: manufacturing-era ROI models translate poorly to service and knowledge work environments, and organisations that cannot demonstrate financial value of improvement work struggle to maintain investment.
What 2023 Holds
Three priorities stand out for LSS practitioners entering 2023. First, the integration of AI and automation with process improvement will accelerate. Tools that surface patterns in process data and predict defect conditions before they occur are moving from experimental to operational. Second, environmental waste is gaining recognition as a legitimate ninth waste -- organisations under ESG pressure are discovering that Lean waste elimination and carbon footprint reduction often point in the same direction. Third, psychological safety is being recognised as a prerequisite for continuous improvement: teams that cannot safely surface problems or challenge standard work will not sustain an improvement culture regardless of how well DMAIC is deployed.
The organisations that will make the most of 2023 treat Lean Six Sigma as a management discipline rather than a project methodology -- building internal capability, embedding improvement metrics into operational governance, and connecting process excellence to strategic objectives so that improvement work competes for resources on equal footing with capital investment.
