Supply Chain Visibility Glossary: The Terms Every Supply Chain Director Should Know

Visibility is the prerequisite for transparency. Without continuous, accurate sensor data, sharing a link with a customer or regulator produces nothing actionable.

Essential Metrics for Tracking Delivery Outcomes

Delivery performance in logistics comes down to a handful of metrics. These are the definitions that matter most for carrier accountability and customer SLA management.

OTIF Benchmarks for Customer SLAs

OTIF (On-Time In-Full) measures the percentage of shipments delivered to the correct destination within the customer's designated delivery window, carrying the complete ordered quantity. Both conditions must pass simultaneously: a shipment arriving on time but missing 10% of the order fails OTIF entirely.

OTIF is a contractual SLA (Service Level Agreement) metric for most major retailers and pharmaceutical customers. Missing it triggers financial penalties, supplier scorecard downgrades, and, in regulated industries, potential compliance investigations. Real-time in-transit alerts allow logistics teams to identify at-risk shipments while there is still time to reroute or expedite.

Measuring Order Accuracy and Real-Time Data

Order Fill Rate is the percentage of total orders shipped complete, measuring how often a customer receives everything they ordered in a single delivery.

Line Fill Rate is more granular, measuring the percentage of individual order lines shipped complete out of all order lines placed. A single order may contain 20 SKUs (Stock Keeping Units), and line fill rate measures fulfillment accuracy at the SKU level rather than the order level.

Real-Time Transportation Visibility (RTTV) is the continuous capture and display of shipment location and condition data as events occur during transit, without reliance on carrier-reported milestone scans. Hardware-based RTTV, where a physical sensor travels with the cargo on a preconfigured transmission schedule, generates first-party data independent of carrier reporting cycles. This distinction determines whether a team can intervene on an exception or can only document it after the fact.

Resolving Supply Chain Disruptions

Exception Management is the process of identifying, prioritizing, and resolving shipment events that deviate from expected parameters, including late departures, temperature breaches, route deviations, and unscheduled stops.

In-Transit Alert is a real-time notification issued during an active shipment when a sensor threshold is breached or a route deviation is detected. An alert issued during transit gives the team a window to reroute or act before a loss is confirmed. A delivery report issued at receipt does not.

Evaluating Partner Service Reliability

Supplier Scorecard rates carriers and suppliers against defined KPIs (Key Performance Indicators) including on-time delivery rate, fill rate, excursion frequency, and damage claims. Scorecards built on continuous sensor data provide objective, timestamped evidence for carrier accountability conversations.

Carrier Performance Metrics are the quantifiable data points used in supplier scorecards, including delivery timing, route adherence, temperature compliance rate, and claim frequency. When sensor data backs these metrics, it provides objective, timestamped records that strengthen carrier accountability conversations and support dispute resolution, though legal defensibility depends on proper data retention and handling policies.

Navigating Cold Chain and Compliance Standards

Regulated and temperature-sensitive cargo moves within strict parameters. The terms below define the standards and events that determine whether a shipment is accepted or rejected.

Managing Temperature Excursions

Temperature Excursion occurs when a temperature-sensitive shipment falls outside its validated storage range during transit, risking product spoilage, regulatory rejection, or write-off.

Mean Kinetic Temperature (MKT) calculates cumulative thermal stress on a pharmaceutical product across fluctuating transit temperatures, weighting higher temperatures more heavily than a simple average to reflect accelerated degradation kinetics. USP (United States Pharmacopeia) General Chapter <1079.2> defines MKT as a single calculated temperature at which the total amount of degradation over a particular time period is equal to the sum of the individual degradations that would occur at various temperatures. Tive Solo Pro displays MKT on its ePaper screen, enabling instant accept or reject decisions at receipt without waiting for a data download.

Ensuring Cold Chain Product Safety

Cold Chain Monitoring is the continuous measurement and recording of temperature and humidity conditions throughout a shipment's journey, from origin to final delivery, using calibrated sensors transmitting on a preconfigured schedule.

Product Integrity is the confirmed state of a shipment's condition, appearance, and compliance with specified parameters at every point in transit and at delivery. For pharmaceutical, life sciences, and perishable food shipments, product integrity cannot be inferred from departure and arrival readings alone. It requires continuous condition data captured between those two points.

The Tive Solo Lite, Solo Pro, and Tive Solo 5G each provide different sensor capabilities depending on shipment requirements. The Solo Pro supports dry-ice probes (to minus 100 degrees Celsius) and cryogenic probes (to minus 200 degrees Celsius) for ultra-cold biologics and gene therapies. The Solo 5G also supports external probes extending below minus 20 degrees Celsius; confirm the exact probe range for your specific shipment requirements with Tive directly.

Verifying Custody Across Handoffs

Chain of Custody is the documented, unbroken chronological record of who had physical control of a shipment, under what conditions, and at what times throughout its journey. Continuous sensor records can support chain of custody documentation in regulatory audits and insurance disputes, though legal defensibility depends on proper data retention and handling policies.

Carrier Handoff transfers custody and responsibility for a shipment from one party to another, such as from a shipper to a freight forwarder or from an ocean carrier to a drayage provider at port. Carrier handoffs are the most common source of visibility gaps because each party's tracking system reports only within its own network. E.T.H. Cargo uses continuous Tive monitoring across every handoff on 200+ pharmaceutical shipments per year, and tracker data at minus 19.67°C disproved a damage claim and avoided a costly investigation.

Meeting Cargo Certification Standards

FDA (Food and Drug Administration) 21 CFR (Code of Federal Regulations) Part 11 is the U.S. regulation that establishes criteria under which electronic records and electronic signatures are considered trustworthy, reliable, and equivalent to paper records. Part 11 compliance requires validated, closed systems with automatic time-stamped audit trails and controlled access. Tive demonstrates FDA 21 CFR Part 11 compliance, but buyers should confirm how this applies to their specific validation program directly with Tive.

EU (European Union) Annex 11 is the GMP (Good Manufacturing Practice) regulation governing computerized systems used in pharmaceutical manufacturing and distribution. Annex 11 requires that all GxP (the umbrella term for Good Manufacturing, Laboratory, Clinical, and related Practice standards) computerized systems be validated before go-live, with computer-generated audit trails recording all GxP-critical data creation, modification, and deletion, including operator identity and timestamp.

GxP Validation is the collective term for the regulations and quality guidelines governing pharmaceutical manufacturing (GMP), laboratories (GLP, or Good Laboratory Practice), and clinical trials (GCP, or Good Clinical Practice). GxP validation ensures that systems consistently produce results meeting pre-determined quality specifications.

FSMA Compliance refers to adherence to the U.S. Food Safety Modernization Act, which mandates preventive controls and traceability requirements for food shipments in the U.S. supply chain.

NIST Traceable Calibration documents a calibration process where a measurement instrument's accuracy traces through an unbroken chain of comparisons back to national standards maintained by the National Institute of Standards and Technology. Tive includes a 3-Point NIST traceable Certificate of Calibration with every tracker, giving auditors verifiable proof that monitoring instruments met a traceable accuracy standard. This is a procurement gate for regulated pharmaceutical and food lanes, not a nice-to-have.

GAMP 5 (Good Automated Manufacturing Practice, version 5) is the pharmaceutical industry's standard framework for the validation of automated manufacturing and laboratory systems, published by ISPE (International Society for Pharmaceutical Engineering). A platform built to GAMP 5 demonstrates that software development, testing, and change management processes meet defined quality standards. Buyers should confirm how Tive's GAMP 5 alignment applies to their specific validation program.

Defining Critical Transportation Visibility Terms

Precise language around transit data separates platforms that detect problems from platforms that merely report them. These definitions draw that line.

Solving Carrier Handoff Data Blindspots

Load-Chasing is the manual process of logistics staff calling and emailing carriers, brokers, and drivers to obtain shipment status updates that lag real events by hours. Load-chasing represents the operational cost of relying on carrier milestone data rather than continuous first-party sensor feeds, consuming team bandwidth that should go toward exception resolution, not status retrieval.

Tracking Multimodal Freight Legs

Multimodal Shipment is a single shipment moving across more than one transportation mode, such as truck to ocean vessel to rail to final-mile delivery, under a single coordination structure. Multimodal shipments are where visibility gaps are most likely and most costly because each mode transition represents a carrier handoff where condition and location data can break. Tive's global cellular, WiFi, and GPS trackers maintain continuous data across all modes, with patented bi-directional connectivity allowing tracker settings to be adjusted while shipments are in transit.

Managing Active Shipment Exceptions

Smart Route Deviation Alerts are automated, real-time notifications issued when a tracked shipment leaves its expected route path. Venture Metals+ caught a route deviation using Smart Route Deviation Alerts and light alerts in time to save a $250,000 shipment.

Smart Reefer Cycle Detection Alerts are automated notifications that flag when a refrigerated trailer's reefer unit stops cycling correctly, enabling logistics teams to act before the cargo inside breaches its temperature range.

Closing Gaps in Transit Visibility

Location Visibility continuously tracks a shipment's geographic position during transit using GPS (Global Positioning System), cellular triangulation, or WiFi geolocation. It answers "where is my shipment?" but does not answer whether the cargo inside is intact or compliant.

Condition Visibility continuously monitors a shipment's physical environment using sensors for temperature, humidity, shock (measured in G-force), light, motion, and tilt. For high-value or temperature-sensitive cargo, condition visibility determines whether a load can be accepted at delivery. Location alone cannot catch a reefer unit failure, a door-open event, or an impact that damaged fragile equipment mid-route. For food and beverage or last-mile shipments where temperature, motion, and light monitoring meet the requirement, the Solo Lite provides a focused sensor set suited to those conditions.

Connecting TMS and ERP Data Flows

System integration determines whether visibility data reaches the teams who need to act on it. The following terms cover how those connections work.

Optimizing TMS for Freight Visibility

TMS (Transportation Management System) manages freight planning, carrier selection, shipment booking, and transportation execution. TMS data typically covers carrier milestones and freight cost tracking. Tive connects directly to TMS platforms via pre-built integrations with Shipwell, Transporeon, Freightgate, FreightPOP, Turbo, and Tai, pushing real-time sensor and location data into the system where logistics teams already operate. WMS (Warehouse Management System) platforms receive Tive data via the public REST API or via a bridging TMS integration such as FreightPOP. There is no native pre-built WMS connector.

Streamlining ERP Data Workflows

ERP (Enterprise Resource Planning) consolidates financial, operational, procurement, and inventory data across the organization. ERP systems receive Tive data via the API or through a bridging TMS integration. For a Supply Chain Director, the distinction between a Customer Shipment (the commercial order recorded within the ERP) and a Transport Shipment (the physical movement of those goods tracked by a TMS or real-time sensor) matters because mismatched records produce financial reporting gaps and delay carrier accountability conversations.

Automating Data Flow with APIs

REST API (Representational State Transfer Application Programming Interface) is a standardized communication protocol allowing external systems to request or write data from a platform. Tive exposes a public REST API (v3, read and write) that allows TMS, ERP, and SCM (Supply Chain Management) systems to pull tracker, shipment, and alert data on demand. API access is available in the Premium tier.

Webhooks are event-driven notifications that automatically push data to a connected system the moment a defined event occurs, such as a temperature excursion, a door-open alert, or a route deviation. The practical difference for a Supply Chain Director is this: an API waits to be asked, while a webhook sends data the moment an exception occurs, meaning your team receives an alert in seconds rather than discovering the problem on the next manual portal check. In practice, webhooks cut the human polling loop by delivering exceptions directly to the operations team's existing tools, including Slack, Microsoft Teams, or Salesforce.

Sharing Live Shipment Data with Partners

Collaborator Roles are permission-based access levels within the Tive Platform that give named external parties (customers, carriers, customs brokers) role-based, login-required access to live shipment data. Tive offers Viewer, Contributor, and Editor roles, configuring how much data partners can see and whether they can make changes. This is where visibility becomes transparency: sharing live data with a key account manager transforms reactive status calls into proactive client communication.

Shareable Links are public, no-login URLs generated within the Platform that provide external parties with a real-time view of a specific shipment without account access. Shareable links allow shipper-facing teams to respond to customer status requests in seconds rather than calling carriers for updates.

Key Financial Definitions for Visibility ROI

Visibility investments are justified or rejected on financial evidence. These definitions anchor the cost-of-inaction case in operational terms.

Managing Inventory Capital Costs

Working Capital is the difference between current assets (inventory, receivables) and current liabilities, representing the cash tied up in goods moving through the supply chain. Real-time in-transit data improves forecast accuracy, reduces safety stock requirements, and frees working capital by giving operations teams verified demand and transit data rather than forcing conservative inventory buffers built around uncertainty.

Safety Stock is the additional inventory held beyond projected demand to absorb variability in lead times and supply. Operations teams that cannot trust in-transit ETAs (Estimated Times of Arrival) maintain inflated safety stock as a hedge. Real-time transit data allows safety stock to be rightsized against actual supply reliability rather than worst-case assumptions.

The True Price of Supply Chain Delays

Demurrage is the charge levied when a shipping container remains inside a terminal beyond the carrier's free time allowance. Demurrage accumulates daily and can escalate after extended free time. Real-time tracking alerts teams when a container approaches its free time limit, enabling prioritized action before charges accumulate.

Detention is the charge levied when a container remains outside the terminal beyond the carrier's free time allowance because it has not been returned on schedule. When charges are disputed, timestamped sensor data provides logistics teams with factual, time-stamped records of the container's location and status throughout its journey, supporting dispute conversations with carriers, though legal defensibility depends on proper data retention and handling policies.

Cost per Exception is the total cost associated with resolving a single shipment exception, capturing the full financial impact of a failure event. The cost-of-inaction framework builds this calculation upward, comparing the monitoring program cost against the financial impact of a single incident caught during transit. Use the Tive ROI Calculator to model this on your active lanes. Semex has recorded zero insurance claims since implementing Tive and recovered a $750,000 shipment in Germany within hours, demonstrating the cost-per-exception logic applied to a real incident.

Building Supply Chain Resilience

Supply Chain Resilience is the organization's capacity to detect, absorb, and recover from supply chain disruptions, including carrier failures, port congestion, regulatory delays, and cargo theft, without material impact to customer SLAs. Resilience builds through faster detection (in-transit alerts that identify problems before they escalate) and faster response (ground-truth data enabling teams to act on verified evidence). Lamaignere cut its air-shipment accident rate by 20% after standardizing on Solo 5G, with per-shipment alerts covering location, shock, temperature, light, and humidity.

Standardizing Vendor Evaluation Criteria

Platform evaluation fails when teams measure different things. These definitions give procurement, logistics, and IT a shared standard before any demo begins.

Vetting Visibility Platform Capabilities

Ground Truth Data is first-party sensor data captured directly by a physical device traveling with the cargo, independent of carrier reporting or third-party data aggregation. Ground truth data reflects what is actually happening to the shipment, not what a carrier reports via an API call. Tive's multi-network trackers generate first-party ground truth data that the shipper controls: they decide what to measure, receive the raw readings, and decide how to act.

Aggregated Data is shipment status information assembled from multiple carrier APIs, logistics partner feeds, and third-party network nodes rather than from a dedicated sensor traveling with the cargo. Aggregated data introduces latency (data reports when carriers report it, not when events occur), gaps (carrier handoffs often produce reporting breaks), and dependency on third-party accuracy. Software-only RTTV platforms depend on aggregated carrier data and can report carrier milestones but cannot measure temperature, detect a door opening, or flag a route deviation from within the cargo itself.

Aligning Stakeholders on Visibility Needs

Before evaluating platforms, align the COO (Chief Operating Officer), CFO (Chief Financial Officer), and logistics leadership on shared definitions to prevent conflicting requirements from stalling procurement. Define what "real-time" means for your organization (continuous sensor transmission, hourly batch updates, or carrier milestone scans), which events require monitoring (location only, or location plus temperature, humidity, shock, and light), which compliance certifications are mandatory for your regulated lanes (FDA 21 CFR Part 11, EU Annex 11, NIST, GAMP 5), which systems must receive shipment data (TMS, ERP, WMS) and via which mechanism (API, webhook, or pre-built connector), and at what cargo value per shipment real-time monitoring justifies itself against a single prevented incident.

Tive has sold more than 4 million trackers across 1,200+ customers globally, reaching $100M+ booked ARR (Annual Recurring Revenue) confirmed in May 2026, providing network-level lane intelligence that newer platforms cannot replicate.

Clarifying Industry Acronyms and Concepts

Acronyms and shorthand vary by organization. The following section standardizes the terms most likely to create misalignment during procurement and audit.

Core Distinctions: Visibility vs. Tracking

Simple tracking provides milestone events (departed, arrived, in customs, delivered) but nothing in between. Visibility provides continuous data between those checkpoints, including real-time location, temperature readings, shock events, and door-open detections, on a schedule configured by the shipper rather than triggered by carrier scans. A shipment that tracks as "in transit" can simultaneously be three hours outside its approved route, twenty minutes into a temperature excursion, and in the hands of an unauthorized third party. Tracking would not show any of that. Visibility would.

Certifications Required for Regulated Cargo

Directors evaluating vendors for regulated lanes must require documentation of the following compliance credentials before procurement:
