- Plan for Every Part (PFEP) & Replenishment
Material availability depends on having the right part, in the right quantity, at the right location, at the right time. Implementation Engineers implements Plan for Every Part (PFEP) and replenishment systems that establish the planning parameters, inventory policies, supplier information, material-flow rules, and management processes required to improve part availability while controlling inventory as part of Plan for Every Part PFEP.
We develop a structured plan for purchased and manufactured parts based on actual demand, consumption, lead time, criticality, supplier performance, inventory requirements, storage, and point-of-use needs. IE then integrates those parameters into ERP/MRP systems and daily supply chain processes so PFEP becomes an active tool for planning and execution—not a static database through effective PFEP implementation.
What We Implement
Plan for Every Part (PFEP)
Create a single source of truth for how every critical part should be planned, purchased, stored, replenished, and delivered.
IE develops PFEP data and planning standards for purchased and manufactured materials based on the requirements of the operation as part of Plan for Every Purchased Part.
Depending on the environment, PFEP can incorporate part usage, demand, supplier, lead time, order quantity, inventory policy, packaging, storage location, point of use, replenishment method, and other information required to effectively manage material availability.
Replenishment Strategy & Parameters
Establish replenishment rules based on actual operating requirements.
IE evaluates demand patterns, consumption, supplier lead times, variability, service requirements, and operational risk to establish appropriate replenishment strategies through part replenishment planning and inventory replenishment.
We optimize parameters such as Min/Max levels, reorder points, safety stock, safety time, order quantities, and replenishment frequency to better balance material availability with inventory investment as part of safety stock optimization and Min Max inventory planning.
Supplier Lead Time & Performance Integration
Connect replenishment decisions to actual supplier capability.
Replenishment parameters cannot be reliable when supplier lead times and performance assumptions are inaccurate.
IE validates supplier lead times, delivery performance, schedule confirmation, and other supply characteristics and integrates this information into planning and replenishment decisions.
Inventory & Material Availability
Improve availability without simply adding more inventory.
IE analyzes shortages, excess inventory, inventory accuracy, material usage, and planning parameters to identify why parts are unavailable when operations need them through focused material availability.
Rather than responding to shortages by increasing inventory across the board, we establish differentiated policies based on demand, lead time, variability, part criticality, and supply risk.
ERP / MRP & Master Data Integration
Put PFEP and replenishment logic into the systems teams use every day.
IE aligns PFEP information with ERP/MRP master data and planning parameters so the system accurately reflects how materials should be managed as part of ERP replenishment parameters.
This can include supplier lead times, safety stock, safety time, routings, inventory parameters, order quantities, material transactions, and other data required to generate more reliable supply signals.
Material Flow & Point-of-Use Replenishment
Connect material planning with physical material movement.
PFEP extends beyond planning parameters. IE defines how materials should flow from receiving and storage through staging and point-of-use consumption.
Where appropriate, we establish standardized replenishment methods, delivery frequencies, storage requirements, presentation quantities, and material-handling processes to support reliable production.
Governance, KPIs & Sustainment
Keep PFEP accurate as demand and operating conditions change.
PFEP loses value if its underlying assumptions become outdated.
IE establishes ownership, review cadences, standard work, KPIs, exception management, and governance processes so teams continually update supplier, demand, inventory, and replenishment parameters as conditions change.
Why Plan for Every Part & Replenishment Matters
Material Shortages Aren’t Always a Supplier Problem
When production stops because a part is missing, the immediate reaction is often to expedite the supplier or increase inventory.
But recurring material shortages can originate much earlier in the planning process.
Supplier lead times may be outdated. Safety stock may not reflect actual variability. Reorder points may be disconnected from consumption. Inventory records may be inaccurate. Demand and production schedules may not be synchronized. Different parts may be managed with the same replenishment logic even though their risk, usage, and supply characteristics are completely different.
Without a disciplined part-level planning process, organizations can experience the worst of both worlds: too much inventory overall while still experiencing shortages of the parts production actually needs.
PFEP creates a structured, data-driven approach for determining how individual parts should be planned and replenished.
By connecting demand, supplier performance, lead times, inventory policy, material flow, ERP/MRP data, and production requirements, organizations can improve material availability while reducing unnecessary inventory, expediting, production disruption, and working capital.
IX® in Action | Military Vehicle Manufacturing
Implementing PFEP to Reduce Critical Material Shortages
A leading military vehicle OEM manufacturing tactical vehicles for U.S. and allied governments was experiencing chronic material shortages that disrupted production and delayed customer deliveries.
More than 300 vehicles were being held in production because of missing parts, tying up approximately $35 million in inventory. Production schedules changed frequently, supplier performance was inconsistent, inventory accuracy was unreliable, and planners lacked the visibility needed to proactively prevent shortages.
IE determined that the shortages extended beyond individual supplier issues. They were being driven by disconnected planning processes, inconsistent supplier management, inventory inaccuracies, limited production visibility, and insufficient cross-functional governance.
As part of the transformation, Implementation Engineers implemented a Plan for Every Purchased Part (PFEP) and strengthened the processes surrounding material planning and replenishment.

Frequently Asked Questions
What is a Plan for Every Part?
A Plan for Every Part (PFEP) is a structured database and process that defines how every critical part should be planned, purchased, stored, replenished, and delivered based on demand, lead time, criticality, and operational requirements.
What information should a PFEP include?
PFEP typically includes part usage, demand, supplier information, lead time, order quantity, inventory policy, packaging, storage location, point of use, replenishment method, and other data required to manage material availability.
How does PFEP reduce material shortages?
By establishing accurate, part-specific planning parameters, validating supplier lead times, setting appropriate safety stock and reorder points, and integrating the data into ERP/MRP systems so replenishment signals reflect actual needs.
What is the difference between PFEP and inventory optimization?
Inventory optimization focuses on overall stock levels and policies. PFEP is a detailed, part-level planning tool that defines how each individual part should be managed and replenished.
How is PFEP integrated with ERP and MRP systems?
PFEP data is aligned with ERP/MRP master data and planning parameters—including lead times, safety stock, order quantities, and inventory settings—so the system generates reliable supply signals.
How often should PFEP data and replenishment parameters be updated?
PFEP data and parameters should be reviewed regularly and updated whenever demand, supplier performance, lead times, or operating conditions change, supported by clear ownership and governance routines.
