Years in Business
Warehouse Strategy$36B medical supplier
After struggling to hit project deadlines, the client had twice postponed its Manhattan Active Warehouse Management (MAWM) rollout from its existing WMOS platform. Technical and operational teams were misaligned, and stakeholders lacked the confidence to go live.
Result
13 fulfillment centers brought live; at peak, configure-test-deploy cycles as fast as 30 days per site.
IBM i / Island Pacific$5B global fashion retailer
A leading global specialty retailer, known for its expansive store footprint and digital presence, was operating on a legacy version of its core merchandise and financial stock ledger system — Island Pacific v1.5, implemented in 2001. With more than two decades of layered customizations and limited vendor support, the client faced increasing operational risk, maintenance complexity, and a growing gap in scalability. A future-ready upgrade was essential — and it had to be executed with zero business disruption, particularly across high-volume sales and merchandise processes.
Result
Island Pacific upgraded to v19.1 with zero impact on sales or merchandise processing; 1,280 custom objects updated in just over 5,000 hours.
Warehouse Strategy$6B fashion retail · Ascena / Knitwell Group
A multi-brand fulfillment center operating several Ascena / Knitwell Group retail brands under one roof needed to meet rising e-commerce demand and address labor constraints in picking and replenishment. The client selected Locus autonomous mobile robots (AMRs) to close the gap — and needed to deploy at scale, integrated with Manhattan WMS, in time for holiday peak shipping.
Result
All 120+ robots live for 2024 holiday shipping; Manhattan WMS integrated, with stronger e-commerce fulfillment productivity.
“I don't want a supplier. I don't want a vendor. I just need a partner willing to go on a journey with us.”
