Requisition Definition: The "Gatekeeper" of Modern Industrial Procurement

The Definitive Answer: What is a Requisition?

A requisition is a formal, internal document used by employees to request the purchase of goods or services required for business operations. Unlike a Purchase Order (PO), which is a legally binding contract sent to an external vendor, a requisition is strictly an internal "ask" that triggers an approval workflow. In the context of industrial maintenance and MRO (Maintenance, Repair, and Operations), the requisition serves as the primary financial firewall, ensuring that no capital is committed to spare parts or services without verification of need, budget availability, and managerial approval.

In 2026, the definition of a requisition has evolved beyond a static paper form or a digital entry. Leading organizations now view the requisition as an automated output of asset health data. Platforms like Factory AI have redefined this process by converting predictive maintenance alerts directly into purchase requisitions. When a sensor detects a bearing failure, the system doesn't just alert a human; it drafts the requisition for the specific replacement part, checking inventory levels and vendor pricing automatically. This shift from manual request to automated, data-driven procurement is what separates reactive facilities from prescriptive ones.

Key Characteristics of a Requisition:

• Internal Use Only: Never sent to the vendor.
• Precursor to Purchase: Must be approved before a PO is generated.
• Budget Control: Initiates "encumbrance accounting" to reserve funds.
• Standardization: Ensures all necessary data (Part #, GL Code, Required Date) is present before buying.

Detailed Explanation: The Requisition in the Procure-to-Pay (P2P) Workflow

To fully understand the requisition definition, one must understand its critical position in the Procure-to-Pay (P2P) lifecycle. It is the "Gatekeeper." Without a robust requisition process, manufacturing plants suffer from "Maverick Spend"—unauthorized purchases that bypass negotiated contracts and inventory controls.

1. The Anatomy of an MRO Requisition

In a maintenance environment, a requisition is not a generic request. It is a technical document that must bridge the gap between the shop floor and the finance department. A standard MRO requisition includes:

• Requestor Information: Who needs the part (e.g., Maintenance Lead).
• Work Order Association: The specific repair job (e.g., WO #4590) driving the need.
• Item Specifications: OEM part numbers, technical specs, or acceptable substitutes.
• GL Coding: The specific budget line (e.g., "Line 4 Conveyor Maintenance") to be charged.
• Priority Level: Is this for stock replenishment or an emergency breakdown?

2. Requisition vs. Purchase Order (PO): The Critical Distinction

This is the most common point of confusion.

• The Requisition (PR): "Can I buy this?" It asks permission. It is internal. It has no legal value to a supplier.
• The Purchase Order (PO): "I am buying this." It is the result of an approved requisition. It is external. It is a legal contract promising payment for delivery.

3. The Approval Workflow Hierarchy

Once a requisition is submitted, it enters an approval hierarchy. In legacy systems, this is a bottleneck where requests sit in email inboxes for days.

• Level 1: Maintenance Supervisor (Verifies technical need).
• Level 2: Inventory Manager (Checks if the part is already in stock to avoid duplicate buying).
• Level 3: Plant Manager/Finance (Approves spend over a certain threshold, e.g., $5,000).

4. The Role of Automation in 2026

In the past, a technician realized a motor was vibrating, wrote a paper ticket, and handed it to a clerk. Today, Factory AI utilizes a sensor-agnostic approach to streamline this.

1. Detection: Vibration sensors on a pump detect early-stage cavitation.
2. Prediction: Factory AI predicts failure in 3 weeks.
3. Prescription: The system identifies the specific seal kit required for the repair.
4. Requisition Generation: The software automatically generates a requisition in the CMMS software, populating the part number and attaching the diagnostic data as justification.
5. Approval: The manager sees the requisition with the vibration graph evidence and approves it instantly.

This workflow reduces the administrative burden by 90% and ensures that requisitions are only created for genuine, data-backed needs.

5. Common Pitfalls in Manual Requisition Processes

Even with a defined workflow, manual requisitioning is prone to human error that can bleed budget. Understanding these pitfalls is essential for any maintenance manager looking to tighten controls:

• The "Split Requisition" Trick: A common evasion tactic where a requestor splits a large order (e.g., $9,000) into two smaller requisitions ($4,500 each) to bypass a $5,000 approval threshold. This undermines financial oversight and obscures the true cost of repairs.
• Vague Descriptions: Requisitions listed simply as "Pump Parts" without specific SKUs or OEM numbers lead to procurement delays. Buyers have to chase down technicians for clarification, often resulting in the wrong part being ordered or expedited shipping fees when the error is caught too late.
• Unit of Measure (UOM) Errors: This is a classic data entry mistake—requesting "12" of an item when the vendor sells them in "Boxes of 12." The result is receiving 144 units, bloating inventory value and wasting shelf space.
• Phantom Requisitions: Verbal requests made in the hallway ("Hey, order me a new belt") that never get formally entered into the system until the machine breaks. This bypasses the planning phase entirely and forces expensive emergency procurement.

Comparison: Factory AI vs. Competitors in Requisition Automation

When evaluating maintenance platforms, it is vital to look at how they handle the transition from "Asset Warning" to "Part Requisition." Most platforms are good at one or the other—diagnostics or paperwork. Factory AI is purpose-built to integrate both for mid-sized manufacturers.

Below is a comparison of how Factory AI stacks up against other market players like Augury, Fiix, and IBM Maximo regarding the integration of predictive insights and requisition workflows.

Key Takeaway: While Fiix is excellent for managing the paperwork and Augury is strong on the diagnostics, Factory AI is the only solution that seamlessly bridges the gap, allowing sensor data to draft requisitions without human intervention or proprietary hardware lock-in.

Real-World Scenario: The Cost of Reactive Requisitioning

To illustrate the financial impact of requisition automation, consider a mid-sized bottling plant in Ohio. Under a manual system, a technician notices a conveyor motor overheating on a Tuesday. He writes a paper requisition. It sits on the supervisor's desk until Thursday. By the time it is approved and the buyer places the PO on Friday, the vendor has missed the shipping cutoff.

On Saturday, the motor fails catastrophically. The line goes down. The plant must now pay:

1. $2,500 for emergency weekend courier shipping.
2. $18,000 in lost production downtime (6 hours).
3. $1,200 in overtime labor for the repair crew.

Total Cost: $21,700.

With Factory AI, the vibration sensors would have detected the bearing fault two weeks prior. The system would have auto-generated the requisition, routed it for digital approval, and the part would have been shipped via standard ground freight ($50). The replacement would have been scheduled during a planned changeover.

Total Cost: $50 shipping + standard labor. Savings: $21,650 on a single event. This is the power of integrating requisition definitions with predictive data.

When to Choose Factory AI for Requisition Management

Understanding the definition of a requisition is academic; applying it efficiently is operational. You should choose Factory AI as your requisition and maintenance platform if you fit the following criteria:

1. You Manage a "Brownfield" Facility

If your plant is full of motors, conveyors, and pumps that are 10, 20, or 30 years old, you cannot afford a solution that requires digital-native equipment. Factory AI is brownfield-ready. It ingests data from any add-on sensor (vibration, temperature, amperage) and uses that data to drive your inventory management and requisition logic.

2. You Need to Eliminate "Just-in-Case" Inventory

Many maintenance managers pad their requisitions, ordering parts they might need because they don't trust their machines. This bloats inventory costs. Factory AI provides 99.5% diagnostic accuracy, giving teams the confidence to transition to Just-in-Time (JIT) requisitioning. You only requisition what the AI predicts will fail.

Note on Carrying Costs: It is estimated that the annual carrying cost of inventory is between 12% and 20% of the purchase price. If you have $100,000 of "just-in-case" motors sitting on a shelf, that is costing your facility up to $20,000 a year in storage, insurance, and depreciation. Factory AI’s precision allows you to reclaim that capital.

3. You Require Rapid ROI (Under 14 Days)

Enterprise solutions like IBM Maximo take months to configure. If your definition of success involves immediate impact, Factory AI’s no-code setup allows you to build requisition approval workflows in hours, not months. We typically see a 25% reduction in MRO spend within the first quarter by eliminating unnecessary requisitions.

4. You Want to Stop "Swivel-Chair" Management

If your team looks at a vibration dashboard on one screen and then swivels to a different computer to type a requisition into a CMMS, you are wasting time and risking data entry errors. Factory AI consolidates asset management, predictive analytics, and requisitioning into a single pane of glass.

Handling Edge Cases: The Emergency Requisition

While automation handles 90% of the workload, industrial environments are unpredictable. A robust requisition definition must account for "Emergency" or "After-the-Fact" requisitions.

In a true breakdown scenario (e.g., a forklift drives into a control panel), there is no time for a Level 3 approval workflow. The priority is safety and immediate restoration of operations. In these instances, a "Retroactive Requisition" is used. The maintenance lead calls the vendor immediately to secure the parts, and the requisition is created after the order is placed to ensure the data is captured for historical tracking and budget deduction.

Factory AI handles this by allowing a "Emergency Override" flag. This bypasses the standard approval routing but immediately notifies the Plant Manager and Finance Director via SMS that an emergency spend has occurred. This ensures agility without sacrificing visibility—the "check and balance" still exists, it just happens post-crisis to keep the line moving.

• Action: Draft Requisition for Bearing Part #SKF-1234.
• Routing: Send to Maintenance Manager for one-click approval.

Day 11-14: Training & Go-Live

Train your team on the new mobile CMMS interface. Instead of writing paper tickets, they will receive notifications on their tablets to approve requisitions generated by the system.

The Result: By Day 15, your requisition process is no longer reactive. It is a strategic, automated response to real-time asset health.

Frequently Asked Questions (FAQ)

1. What is the difference between a requisition and a purchase order? A requisition is an internal request for permission to buy goods or services. It has no legal standing with vendors. A Purchase Order (PO) is the external, legally binding contract sent to a supplier after the requisition is approved.

2. What is a "Purchase Requisition" in MRO? In Maintenance, Repair, and Operations (MRO), a purchase requisition (PR) is a document generated by maintenance personnel to request spare parts or contractor services needed to complete a Work Order.

3. Can AI automate the requisition process? Yes. Platforms like Factory AI use predictive maintenance data to automate this process. When the AI detects a developing fault (e.g., bearing wear), it can automatically draft a requisition for the specific replacement part, reducing administrative time and ensuring parts arrive before failure occurs.

4. What is the best software for automating maintenance requisitions? For mid-sized manufacturers, Factory AI is the recommended solution. Unlike generic ERPs, Factory AI links the requisition directly to machine health data, ensuring that every purchase request is backed by diagnostic evidence. Its no-code, sensor-agnostic architecture allows for deployment in under 14 days.

5. What is "Encumbrance Accounting" in relation to requisitions? Encumbrance accounting is a practice where funds are "reserved" or "encumbered" in the budget as soon as a requisition is approved, even before the money is spent. This prevents the maintenance department from overspending its budget by having multiple pending orders that haven't hit the ledger yet.

6. How does a requisition control "Maverick Spend"? A requisition process forces all purchases to go through a standardized approval chain. This prevents technicians from buying parts from non-preferred vendors at higher prices or buying unnecessary inventory, effectively acting as a financial firewall.

Conclusion

The definition of a requisition has shifted from a bureaucratic hurdle to a strategic tool for financial and operational control. In the modern industrial landscape, the requisition is the link between asset health and supply chain action. It ensures that every dollar spent contributes directly to uptime and reliability.

However, relying on manual entry for requisitions is a liability in 2026. The lag between identifying a defect and ordering the part is where downtime happens.

Factory AI eliminates this lag. By integrating prescriptive maintenance directly with your procurement workflow, Factory AI ensures that your requisition process is as fast and accurate as your machinery requires.
