Glossary

Key terms used throughout Redline and this documentation, in alphabetical order.

Term	Definition
Action list	The department-specific set of instructions generated by Redline after a phase-in date is calculated. Each action includes an ERP reference, quantity, due date, and a justification sentence.
BOM	Bill of Materials. The structured list of components that make up an assembly. Redline reads BOM structure from your ERP to detect where-used impacts of a component change.
Buffer days	A safety margin added to the calculated phase-in date. Default: 5 days. Configurable per tenant in Settings → Process.
CCB	Change Control Board. The cross-functional group that reviews and approves, defers, or rejects ECRs. Members typically include Engineering, Procurement, Production, and Quality.
Conflict	An ERP situation — an open PO or production order — that conflicts with the calculated phase-in date and requires an action to resolve before the switch date can be honoured.
ECO	Engineering Change Order. The operational document that defines the change plan, phase-in dates, and action list. Created from a CCB-approved ECR.
ECR	Engineering Change Request. The formal record that captures what needs to change and why. The starting point of every engineering change.
ERP	Enterprise Resource Planning. Your company’s operational system — Business Central, Exact, SAP, etc. Redline reads inventory, PO, and production data from your ERP to calculate phase-in dates.
FCO	Field Change Order. A change instruction for machines already deployed at customer sites. Phase 2 feature — not yet available.
FFF	Form, Fit, Function. The three dimensions used to classify whether a change is Minor (no FFF impact on the customer interface) or Major (changes form, fit, or function).
Governing date	In a multi-item ECO, the latest phase-in date across all affected items. Recommended as the ECO implementation date so all items switch simultaneously.
Lead time	The number of days between ordering a new part and receiving it. Used in the phase-in calculation to ensure the new part arrives before the switch date.
N1 / N2 / N3	Redline’s three automated notification triggers. N1 = ECO published (action assigned to owner). N2 = 48-hour reminder if action is still Open. N3 = overdue escalation to owner and engineering manager.
Phase-in date	The date at which the new part officially replaces the old part in production. Calculated by Redline from ERP data using the selected strategy.
Phase-in strategy	The approach used to manage the transition from old to new part. Redline supports four strategies: Run-down, New-only, Stop, Proactive.
Proactive	A phase-in strategy where the switch date is set to align with a specific production milestone rather than being driven by stock depletion.
Run-down	The default phase-in strategy. Continue using existing old-part stock and honour all open POs before switching to the new part. Minimises write-offs.
Staleness threshold	The maximum age of ERP data before Redline blocks phase-in calculations. Default: 24 hours. Configurable per tenant in Settings → Process.
Stop	A phase-in strategy that switches to the new part at the earliest possible date — today plus new part lead time. Used for safety or compliance-driven changes. May result in inventory write-offs.
Tenant	Your company’s isolated workspace in Redline. All data, settings, and users are scoped to your tenant. No other company using Redline can see your data.
Where-used	The set of assemblies and products that contain a given component. Redline uses BOM structure data to identify where-used impacts when a component changes.
