How Entegris replaced a decades-old AS/400 with 24 custom Fiori apps, then built a paperless plant floor
Delivered 2019–2026
Mindset replaced Entegris's aging AS/400 plant system with a 24-app, 100% custom SAPUI5 suite on ruggedized Android tablets, and carried that UX through acquisition integrations, from CMC Materials across 8 plants to a paperless plant in Taiwan.

Before
A failing AS/400 and a fragmented acquisition trail
- A decades-old AS/400 plant system running critical manufacturing and inventory tracking, with no modern interface and no safety net.
- Acquired businesses on separate ERPs, creating gaps in order-cycle and costing visibility that only widened over time.
- A plant-floor process with no SAP standard match and workers relying on paper worksheets and Excel printouts.
After
A modern plant floor on SAP, from the AS/400 to Taiwan
- 24 custom SAPUI5 apps on ruggedized Android tablets, replacing the AS/400 with real-time cost and process visibility across the plant floor.
- CMC Materials, Sinmat, ITS/Reno, and KSP Taiwan all brought onto a common SAP platform through structured, phased integration programs.
- A paperless plant UX in Taiwan and a GCP BigQuery rebuild of batch where-used logic extending the platform into 2026.
“The development team on this project continues to complete all planned and unplanned deliverables with ease and excitement. A hats-off to this team for all that you do to support this project. So great to have a group that rises to the challenge presented. We are successful because of the commitment and teamwork on this project.”
Why this matters
When your manufacturing process doesn't match SAP standard, you build 24 apps from scratch on a ruggedized Android tablet. Entegris did exactly that, then kept going through four acquisitions, a paperless Taiwan plant, and a GCP data rebuild.
The challenge
Entegris makes the advanced materials and contamination-control products that semiconductor fabs can't run without. Its plant operations were running on an AS/400 system old enough that going down wasn't a question of if but when. A failure would have cut off the team's ability to track manufacturing processes and inventory at exactly the wrong moment.
At the same time, Entegris was acquiring businesses. CMC Materials, Sinmat, and others joined the portfolio, each bringing its own ERP, its own data model, and its own way of tracking orders and costs. Folding those companies onto a common SAP platform quickly was not optional: the gaps in order-cycle and costing visibility that come from running acquired companies on their old systems compound fast.
On the plant floor, the manufacturing process didn't map to SAP standard. That meant no out-of-the-box path to track billet state, record time and cost per process step, or give plant workers a modern mobile interface. Everything useful would have to be built from scratch.
What we did
Mindset started with a Design Thinking workshop at its Minneapolis AppHaus, then went to the plant floor to map every process and every touchpoint that wasn't in SAP yet, including the Excel printouts and paper worksheets workers were actually using. That discovery drove the design. Prototypes went back to plant users in iteration cycles before a line of production code was written.
The result was a suite of 24 SAPUI5 apps, 100% custom, built to run on ruggedized Android tablets on the plant floor. The apps used SAP DMS documents to track billet state through each step and custom cost collectors to record the time and cost incurred per process. The suite was built and delivered in 26 weeks.
When Entegris acquired CMC Materials, Mindset ran the integration: converting CMC's Oracle ERP and data into Entegris SAP ECC 6.0 across 8 plants, delivered in 4 releases over 12 months with a blended US and India team. The same pattern repeated at Sinmat and other sites. Later work included a paperless plant UX built in Taiwan for the KSP plant (co-presented at SAP Sapphire 2024), a facility implementation in Reno, NV, and a 2026 rebuild of SAP batch where-used logic using GCP BigQuery and Python.
The outcomes
The AS/400 was retired. In its place, Entegris plant teams got a mobile, tablet-capable app suite with real-time visibility into costs and time spent at every step of the manufacturing process. Productivity and mobility both went up. The project earned Entegris the Most Innovative UX award at Mindset's 2023 EXperts Awards, recognized by Entegris's own CIO on a public stage.
The CMC Materials integration brought 8 plants onto the Entegris SAP platform in 12 months across 4 structured releases, eliminating the ERP fragmentation that comes with acquisitions and giving leadership consistent order-cycle and costing data across the combined business.
By 2024, the plant floor work had grown to include a paperless plant UX for Entegris's Taiwan facility, co-presented at SAP Sapphire. The 2026 BigQuery and Python rebuild of batch where-used logic extended the same commitment to modernizing whatever the plant floor still needed.

If we built this today
Concept · not delivered scopeThe plant floor that thinks ahead.
This is a forward-looking concept, not the scope we delivered on this engagement. It is the build we would reach for now, grounded in SAP that ships today.
The 24 custom apps that replaced the AS/400 still need a person to spot a stalled process step or a cost overrun, so the obvious next build is an agent watching billet state, time, and cost as the work happens.
The data product
Cloud ERP Intelligence
Grounds the agent in real plant data, joining order, batch, and costing signals across the rollout so a recommendation reflects what is actually happening on the floor, not a stale extract. It runs against your S/4HANA, no data copy.
Intelligent Application on SAP Business Data Cloud
The Joule agent
Production Order Healer
Reads production and process orders, DMS billet-state documents, and the cost-collector postings that record time and cost per step, then flags orders drifting off plan and drafts the confirmation, rework, or reroute that gets them back on track. A line lead approves before anything posts.

The Fiori app
Production-order management apps with SAP Digital Manufacturing
The standard production-order and confirmation apps now have Joule embedded, with AI-assisted execution coming through SAP Digital Manufacturing, so an operator can ask why an order stalled and get the next step right on the tablet. Where your process is custom enough that no standard app matches, this is the pattern your own apps would extend rather than replace.
Joule embedded in the Fiori launchpad
We would mine the real plant process in SAP Signavio first, map the app and integration estate in SAP LeanIX, and lean on MIND accelerators to carry the custom logic from the old apps to the new ones.

A look at the work
Presented publicly
We took this work to the SAP stage.
At Entegris's new Kaohsiung factory in Taiwan, Mindset replaced pen-and-paper plant work with real-time SAP at the worker's fingertips on the floor. Built for non-English-speaking operators and designed to run on ECC today and move to S/4HANA, it cut data-entry errors, rework, and training cost.
