Textron pulls in a delivery and your heat-treat vendor finds out three days later in a phone call
When a Tier-1 OEM pulls in or pushes out a schedule, your whole sub-tier supply chain has to react, and if that happens by phone and email, you are always three days behind. Custom supply chain software that propagates schedule changes to your suppliers and tracks long-lead material runs $70k to $160k and 5 to 9 months for a Wichita supplier. SAP and generic SCM (Supply Chain Management) assume a stable plan and your reality is anything but.
A Wichita aviation supplier sits in the middle of a long chain: an OEM like Textron or Spirit on one side, and your own sub-tier vendors (forging houses, heat-treat shops, NADCAP processors, raw-material distributors) on the other. When the OEM changes a schedule, that change has to cascade down to every sub-tier with the right lead-time math, or you end up with material arriving for a job that moved or, worse, no material for a job that pulled in. Today that cascade happens by phone, and it is slow and error-prone.
Generic SCM and SAP modules assume a relatively stable demand signal and clean master data. Aviation does not work that way: long-lead titanium and specialty alloys, schedule volatility from the OEM, and sub-tier vendors who themselves have capacity constraints. The off-the-shelf tools either cost a fortune to configure for this or simply cannot model the multi-tier, long-lead reality, so the real planning lives in a planner's spreadsheet and their phone.
The fix: supply chain built for Wichita, not rented
Custom supply chain software models your actual multi-tier chain and long-lead materials, then propagates OEM schedule changes down to sub-tier vendors with correct lead-time math, automatically. Planners stop working the phones and start managing exceptions, and you stop getting caught with material out of phase with a moved schedule. That is the difference between reacting in days and reacting in hours.

How long it takes, phase by phase
Exactly what you get
Supply chain software that turns OEM schedule volatility from a phone-tree scramble into managed exceptions. It propagates pull-ins and push-outs down to your heat-treat, forging, and material vendors with correct lead-time math, plans long-lead titanium and alloys against real demand, and gives vendors a portal to confirm. It integrates with your ERP, inventory management, and warehouse systems so material status is one truth.
How to choose a developer in Wichita
Choose a team that can whiteboard your multi-tier chain and the lead-time math before quoting. A serious Wichita partner understands long-lead aerospace materials and sub-tier capacity constraints, and will design schedule propagation around them. If they only model your direct vendors, they have missed the entire problem.
- Automatic propagation of OEM schedule changes to sub-tier vendors with lead-time math
- Long-lead material planning for titanium and specialty alloys against real demand
- Sub-tier vendor capacity and lead times modeled, not guessed
- Exception-based planning so planners manage problems instead of working phones
- Visibility across the whole chain so a pull-in does not catch you with the wrong material
- Multi-tier supply chain modeling is genuinely complex and not cheap
- It depends on sub-tier vendors sharing reliable lead-time and capacity data
- Demand volatility means the model needs ongoing tuning
- If your supply chain is short and stable, this is over-engineering
- !They cannot model multi-tier vendors, only direct ones
- !No long-lead material planning
- !Schedule changes still rely on manual notification
- !No vendor portal or data exchange plan
- !They underestimate the complexity to win the deal
Teams investing in supply chain in Wichita usually scope it next to project management, helpdesk & ticketing, crm, since these systems share data and budgets.

Frequently asked questions
Why can't SAP or generic SCM handle this?
They assume a relatively stable demand signal and clean master data. Aviation supply has volatile OEM schedules, long-lead specialty materials, and multi-tier vendors with their own constraints, which generic SCM either cannot model or costs a fortune to configure.
How does schedule-change propagation work?
When an OEM pulls in or pushes out a delivery, the system recalculates lead times down your sub-tier chain and notifies each vendor automatically, so a heat-treat shop knows in hours, not in a phone call three days later.
Does it depend on our vendors participating?
Partly. A vendor portal lets sub-tiers see schedules and confirm, and the value grows as more participate, though the core planning works from your own lead-time data.
Will it plan long-lead materials?
Yes. Titanium and specialty alloys with long lead times are planned against real demand so a schedule change does not leave you with material out of phase.
What does it cost?
A schedule-propagation system with a vendor portal runs $70k to $110k. A full multi-tier SCM with long-lead planning is $110k to $160k over 6 to 9 months.
