From AI Proof of Concept to Production: A Tiered Rollout at a $340M Agricultural Equipment Distributor
By Ed Hitchcock, Enterprise AI Systems Architect, SupplyTech Solutions
Most mid-market distributors we meet have already run one or two AI experiments. A ChatGPT pilot in customer service. A Copilot rollout that nobody used after week three. A vendor demo that promised "predictive parts ordering" and never made it past the sandbox. When these fail, the reflex is to blame the technology or the company. Both are usually wrong. What failed was scoping. The team ran an AI proof of concept without a defined path to what comes after it.
This post walks through a 26-week engagement with an agricultural equipment distributor that avoided that trap by treating the AI proof of concept as the first tier of a three-tier path, not a standalone experiment. We call the tiers Lite, Advanced, and Expert. Each tier is useful on its own. Each assumes the previous one has stabilized. Each is defined by the enterprise mechanics it adds, not the model version underneath it.
The Client and the Prior Failure
The distributor runs $340M in annual revenue across 14 dealerships in the Midwest and Great Plains. Roughly 380 employees. Product mix spans compact tractors, hay and forage equipment, precision planters, sprayers, tillage, and a growing aftermarket parts business (about 41,000 active parts SKUs). Core systems: Infor CloudSuite Distribution on-prem, Salesforce Sales Cloud for retail leads, and a homegrown Access database that dispatch built in 2014 and nobody has touched since.
Before we arrived, the CFO had approved $340K for a "predictive parts demand" pilot from a vendor that shall remain nameless. Five months in, the model produced weekly forecasts the parts team ignored, because the forecasts assumed a data structure the ERP did not actually maintain. The engagement ended with $210K spent, zero parts orders influenced, and a leadership team that had quietly written "AI" off as a category.
A failed POC does not just waste money. It burns the political capital required to try again. That is what makes the AI proof of concept phase so dangerous when it is scoped as a one-off.
The Three-System Frame Behind AI Proof of Concept Tiering
We proposed a tiered product path. The distributor bought the frame before they bought the roadmap, which is the correct sequence.
The frame borrows from mature enterprise platforms: a Lite tier for fast execution value, an Advanced tier that adds enterprise mechanics, and an Expert tier that adds optimization. We applied it to AI the same way. Each tier is bounded, testable, and useful in production. Nothing gets built for Advanced until Lite is running and stable in the hands of end users.
Lite is the AI proof of concept. One workflow, one narrow model, sources cited on every response, deployed to a small group of named users who report weekly on what breaks. Designed to be shut off in a day if it does not earn its keep. Advanced adds enterprise mechanics: structured data objects, role-based access, exception workflows, audit logs, integrations that survive a Monday morning. Expert adds optimization: predictive exceptions, cross-workflow orchestration, analytics that inform planning. Most mid-market distributors will not reach Expert in year one. Most should not try.
Weeks 1 to 6: The Lite Tier (AI Proof of Concept)
We picked one workflow. Parts counter lookups. Every morning, parts counter staff answer roughly 190 calls across the network asking whether part X fits equipment Y. Staff toggle between three systems (Infor for pricing and stock, an OEM parts portal for compatibility, a shared network drive of manufacturer PDFs) and often ask a senior tech to confirm. Median call time was 6.4 minutes. Customer wait to reach an agent added another 4 minutes.
The AI proof of concept was a single retrieval-grounded assistant inside Microsoft Teams, answering parts compatibility and pricing questions for internal staff only. Every answer cited the source PDF and the Infor record it pulled from. The assistant refused questions outside its scope. It had access to a curated subset of manufacturer PDFs, the Infor parts master, and the Infor stock table. Nothing else.
We deployed to 12 named parts counter agents across three dealerships and ran it for four weeks with weekly office hours where agents told us what it got wrong. Response accuracy on compatibility questions started at 71% in week one and stabilized at 88% by week four. Agents adopted it voluntarily by week two. Median lookup time on covered question types dropped from 6.4 minutes to 2.1 minutes.
That was the proof. Not a demo. Real questions from real agents against real inventory, with a shutdown switch we tested twice. The Lite tier proved the AI proof of concept model could handle a bounded workflow without embarrassing anyone. Critically, we did not build anything else during weeks 1 to 6. No dashboards. No integrations. No expansion. The team focused on one thing and finished it.
Weeks 7 to 16: The Advanced Tier
Advanced added the enterprise mechanics that the AI proof of concept deliberately skipped. The Lite assistant was a demo of feasibility. Advanced was where it became a system.
Five additions in this phase. First, role-based access control across the Teams deployment so a service manager saw different tools than a parts counter agent, and nobody outside parts could access the assistant. Second, structured audit logs of every query and response, stored in SharePoint and reviewed weekly by the parts ops lead. Third, an exception workflow: low-confidence answers or stock discrepancies created a Power Apps ticket the parts ops lead triaged the same day. Fourth, a Salesforce integration so calls from known customers with open service tickets surfaced that context automatically. Fifth, we onboarded the remaining 34 parts counter agents across all 14 dealerships in staggered cohorts of 6 to 8, with 90-minute training and a two-week shadow period.
By week 16, the assistant answered roughly 68% of eligible internal parts questions across all dealerships. Agents handled the other 32% directly, mostly niche compatibility on discontinued models. Median lookup time on covered questions held at about 2 minutes. The exception queue averaged 14 tickets a week, a signal the guardrails were working.
We also added a doc-review agent for a second bounded workflow. When new manufacturer service bulletins arrived (roughly 40 per month), the agent produced a two-paragraph summary tagged by equipment family and flagged bulletins requiring a customer notification. The service ops lead approved or rejected each summary before it landed in the KMS. Approval rate settled at 91% by week 14.
Weeks 17 to 26: The Expert Tier (Selective)
Expert is where optimization enters. We were selective. Most mid-market distributors do not need the full Expert surface. This client wanted two capabilities.
The first was a reorder-risk analyzer. Not a demand forecaster, which is what the failed prior pilot tried. A risk analyzer. It flagged parts SKUs where current stock, trailing 90-day pull rate, and incoming PO schedule combined to produce a stockout risk in the next 30 days. The buyer team saw the list every Monday morning in a Power BI dashboard, sorted by revenue impact and by the number of open service tickets depending on the part. Buyers accepted or dismissed each recommendation. By week 26, the analyzer surfaced about 45 SKUs per week, and buyers acted on roughly 60% of alerts within one PO cycle (cohort of 210). Against a control set of comparable SKUs, we estimated the analyzer prevented 17 to 24 stockout events per month.
The second Expert capability was a settlement-side integration. When a service ticket closed with parts consumed and labor recorded, an agent drafted the customer invoice narrative and pre-populated warranty claim details where the equipment was under warranty. The service manager approved or edited before the invoice went out. Approval rate on drafted narratives ran at 89%. Time from service ticket close to invoice sent dropped from 3.2 days to 0.8 days on covered cases.
We stopped there. The client had budget for more. We recommended not spending it until the Expert capabilities had six months of operating data behind them. That recommendation cost us roughly $85K in scope. It also earned us the retainer for year two.
Governance and Handoff
Every tier treated governance as a first-class deliverable. We wrote a one-page guardrail policy naming the human owner for each AI capability (parts ops lead for the assistant, service ops lead for the doc-review agent and settlement drafter, procurement director for the reorder-risk analyzer). Every AI output cited its source. Every drafted action required approval. Every capability had a documented shutdown procedure and a named person authorized to execute it.
By week 25, we ran the handoff. The distributor promoted one of the parts ops leads into a new "operations AI lead" role. That person now owns the AI backlog, the exception queue, and the guardrail policy. We meet monthly for six months, then quarterly.
What the Metrics Actually Showed
Parts counter lookup time on covered questions: 6.4 min to about 2 min
Assistant coverage of eligible internal parts questions: 68% by week 16
Doc-review agent approval rate on drafted summaries: 91%
Reorder-risk analyzer buyer action rate: about 60% within one PO cycle (cohort of 210)
Estimated stockouts avoided: 17 to 24 per month
Service ticket close to invoice sent on covered cases: 3.2 to 0.8 days
Settlement drafter approval rate: 89%
Total team admin time eliminated: roughly 12 to 18 hours per week across parts counter, service, and procurement
Automation coverage on targeted workflows: about 40%
Incremental Azure and OpenAI spend: approximately $2,100 per month
Net new SaaS licenses added: zero
When the Tiered Path Is the Right Shape
The tiered AI proof of concept to Advanced to Expert path fits distributors who spent money on a failed AI pilot and want to avoid a second one. It fits leadership teams who can commit to shipping one bounded workflow before starting the next. It fits organizations willing to hire a named operations AI lead by the end of the engagement.
It does not fit teams that want a full transformation program in twelve weeks. It does not fit companies where ERP data is so degraded that the Lite tier would generate more errors than answers. Those companies need a data hygiene phase before the AI proof of concept begins.
The tiered model is not about starting small because AI is scary. Enterprise mechanics accrete in a specific order, and skipping the order is what makes AI implementations fail. Structured data before agents. Role-based access before scale. Exception workflows before optimization. Named human owners before autonomy. The tiers force that order.
We run this pattern for distributors in the $200M to $600M range. If your last AI pilot ended the way this client's first one did, the second one does not have to.
