~10-Point Operating Margin Expansion Through 80/20 Simplification
ITW grew operating margin from 17% to 26.8% by cutting SKUs 50-80% and exiting tail customers in every business unit.
Illinois Tool Works, a Large Enterprise Manufacturing company, created value through Product Mix Shift and Delivery and Fulfillment and Supplier and Input Costs.
Illinois Tool Works entered 2012 with over 800 autonomous business units spread across more than 60 segments. Operating margins hovered around 17%—respectable for a diversified industrial manufacturer but well below what its leadership believed the underlying businesses could deliver. The complexity was structural: each unit maintained its own customer base, product catalog, supply relationships, and management overhead. Many units served long-tail customers who ordered infrequently, required custom configurations, and demanded high service intensity relative to the revenue they generated. The resulting manufacturing footprint was fragmented, setup times were high, and raw-material purchasing leverage was diluted across hundreds of buyer relationships.
In late 2011, incoming CEO Scott Santi commissioned a comprehensive strategic review. The analysis confirmed what 80/20 analysis revealed at the unit level: roughly 20% of customers and products accounted for approximately 80% of revenue and an even higher share of profit. The remaining 80% of the customer and SKU base was consuming a disproportionate share of manufacturing capacity, working capital, and management attention while contributing minimal margin. The 2012 Enterprise Strategy, launched publicly that year, defined ITW's response: systematically apply 80/20 Front-to-Back analysis across every business unit to eliminate complexity, then redeploy the freed capacity and capital toward the high-value core.
ITW's 80/20 Front-to-Back process worked in sequence within each business unit. Management first conducted a rigorous customer and product segmentation: rank every customer by revenue contribution, identify the top roughly 20%, and classify the remaining accounts as tail. The same analysis was applied to the SKU catalog. Once complete, the unit faced a structured decision on the tail: raise prices sufficiently to earn an acceptable margin on the complexity, or exit the volume. In most cases, tail customers were repriced out or allowed to defect to lower-cost competitors. Tail SKUs were discontinued. Manufacturing capacity freed by this simplification was redirected toward serving core customers better—faster lead times, tighter tolerances, more engineering support. In many divisions, SKU counts fell 50–80% and the manufacturing lines formerly dedicated to low-volume specialty orders were consolidated or eliminated. The 80/20 analysis was not a one-time restructuring event but a continuous management discipline embedded into each division's operating rhythm.
Business Structure Simplification ran in parallel. ITW consolidated 800+ autonomous units into 84 scaled divisions, each with significantly larger revenue bases—average revenue per division rose from roughly $25 million to $100 million. The larger scale gave each division the budget to invest meaningfully in engineering, sales, and global supply chain infrastructure that the prior fragmented structure could not afford.

Portfolio Management addressed the subset of businesses where simplification alone could not achieve ITW's margin targets. Between 2012 and 2016, ITW divested approximately $5 billion in revenue from structurally marginal businesses, including the $3.2 billion sale of the industrial packaging segment in 2014. Proceeds funded share repurchases and disciplined tuck-in acquisitions where the 80/20 playbook could be applied immediately. In December 2021, ITW acquired the MTS Test & Simulation business from Amphenol for $750 million and applied its Front-to-Back simplification methodology to reduce lead times and product complexity.
Strategic Sourcing was the fourth component. By consolidating hundreds of purchasing relationships into larger divisional clusters, ITW generated over $900 million in cumulative sourcing savings from 2013 forward, averaging approximately 1% of spend reduction per year.
From 2012 to 2023, ITW expanded operating margin by more than 9 percentage points—from approximately 17% to 25.1%—while simultaneously divesting $5 billion in lower-margin revenue. In 2024, operating margin reached a record 26.8%, with enterprise initiatives contributing 130 of the 170 basis points of improvement that year. Six of seven segments expanded margins in 2024; two exceeded 30% (Welding at 32.3%, Specialty Products at 30.3%). After-tax return on invested capital reached 31.2% in 2024, up from 30.4% in 2023, placing ITW among the highest-ROIC large-cap industrials in its peer group.
Over the full 2012–2023 strategic phase, earnings per share more than tripled, dividends per share grew 3.7 times, and market capitalization more than tripled—returns that outpaced both the S&P 500 and ITW's industrial peer group on a total shareholder return basis. The 2024 revenue base of $15.9 billion was deliberately smaller than the pre-divestiture portfolio, but structurally superior in quality: 84 divisions each averaging roughly $100 million in revenue, operating at margins that would have been unachievable within the prior 800-unit, 60-plus-segment structure. The Welding and Food Equipment segments, each of which completed full 80/20 transformations in the early enterprise strategy years, illustrate the endpoint: both now generate segment operating margins consistently above 27%, compared to blended company margins below 17% at the outset.
Three conditions made ITW's margin transformation durable rather than a one-cycle cost squeeze. The 80/20 analysis was embedded as a continuous management discipline, not a restructuring project with a defined end date. Every division runs customer and product ranking on an ongoing basis; the tail is not allowed to regrow. This created a self-reinforcing dynamic: eliminating tail complexity freed manufacturing capacity that could be directed toward core customers, improving delivery quality and engineering responsiveness for the accounts generating most of the revenue, which in turn strengthened those relationships and reduced churn risk at the top of the customer pyramid.
Business Structure Simplification was a necessary precondition for the economics to hold. A division with $25 million in total revenue that applied 80/20 strictly might be left with $5 million in core revenue—too small to sustain engineering investment, global supply chain relationships, or customer-facing sales capacity. By consolidating to $100 million-average divisions before or concurrent with simplification, ITW ensured the resulting focused businesses were large enough to reinvest in the capabilities required to serve core customers well. Without this consolidation, the 80/20 cuts would have created underfunded stubs rather than high-margin growth platforms.
Strategic Sourcing savings provided the cash buffer that let divisions absorb short-term revenue loss from tail customer exits without compressing near-term margins below acceptable thresholds. The $900 million in cumulative sourcing gains reduced the organizational pressure to retain low-margin volume for coverage, which is the primary reason most 80/20 programs stall: divisions protect the tail because losing the revenue feels riskier than keeping the complexity. ITW's sourcing model removed that trade-off.
