Can your shop see a bottleneck forming before it stops a job – or only after something is already late? If the honest answer is “after,” you are not alone. We work with make-to-order and high-mix discrete manufacturers who still find themselves firefighting the same constraint problems week after week. The issue is rarely effort. It is visibility. That is why we built Protected Flow Manufacturing (PFM)™ – to give your team a practical early-warning system for bottlenecks that works alongside the ERP you already have.
Why ERP Cannot Fill This Gap
ERP manages orders, inventory, purchasing, and financials well. Where it is inferior is in real-time, risk-based shop floor visibility. Dispatch lists reflect a plan created in the past. Due date is typically the primary sorting mechanism, so nothing in the view accounts for how much work remains on a job or which resource is already under pressure. By the time the ERP view shows a resource in trouble, jobs are often already late.
That is the gap we built PFM to fill.
How Threat Level Functions As Bottleneck Prediction
Protected Flow Manufacturing (PFM)™ is not a scheduling tool. It is a dynamic, real-time prioritization system that continuously directs work based on Threat Level.
Threat Level is how much each job is at risk of being late. Due date and customer are important inputs to that calculation, but they are not the driver. Due date specifically is an important input, but it is not the driver. Threat Level is the default driver. Customer is a field that may override Threat Level if needed, so Threat Level is the default but can be overridden when your business rules require it.
Threat Levels are not manually assigned. They are calculated in real time for each operation at each resource area, using approved data from your ERP, machines, and other sources. When conditions change – a breakdown, a rush order, a late material delivery – Threat Levels are recalculated and the list at each work center reshuffles automatically.
When multiple high Threat Level jobs begin accumulating at the same work center, that concentration is visible before the jobs go late. Supervisors do not have to walk the floor to find the pressure point.
Think of it like GPS navigation. Traditional planning is like printing directions before you leave – accurate when created, useless when traffic changes. PFM watches actual conditions and continuously reroutes work toward on-time completion.
PFM works alongside ERP. It reads the data ERP already holds and uses it to generate real-time prioritization across the shop floor. Progress data can come from multiple sources – captured in PFM, fed via machine data collection tools, or sourced from the ERP itself. PFM only optionally sends information back to the ERP.
If your shop is still finding bottlenecks by walking the floor or waiting until an order is already late, the problem is not your people. Contact LillyWorks to see Protected Flow Manufacturing (PFM)™ in action.
FAQs About Bottleneck Prediction Software And PFM
Is Bottleneck Prediction Software The Same As A Scheduling Tool?
No. A scheduling tool produces a fixed sequence of jobs based on a plan created at a point in time. PFM is a dynamic, real-time prioritization system that directs work based on Threat Level, recalculated continuously as conditions change.
How Is Threat Level Different From Just Sorting By Due Date?
Due date tells you when a job is supposed to be done. Threat Level tells you how much risk exists right now that it will not make that date. Two jobs can share the same due date but carry very different Threat Levels depending on how much work remains and what other jobs are competing for the same capacity. Threat Level is the default driver – due date is an important input, but it is not what drives the prioritization.
Do We Need To Replace Our ERP To Get Better Bottleneck Visibility?
No. PFM works alongside your ERP. ERP remains the system of record. PFM reads that data, calculates Threat Levels in real time, and gives your team a live view of where risk is building on the shop floor.
