LOG iN eKANBAN

Electronic kanban, also called eKanban, is the digital version of the traditional kanban system used in lean manufacturing to manage the supply of materials to production lines.

The principle is the same as physical kanban: pull logic. Downstream consumption (on the line) automatically generates a replenishment request upstream (from the warehouse). Material is not produced or moved based on a forecast: it is moved based on real consumption. Only what is needed, when it is needed, in the quantity needed.

The difference from paper kanban is in the execution. In physical kanban, the signal is a card or an empty container that an operator must move manually. In electronic kanban, the signal is generated by the system the moment consumption is detected, through scanning, production data or operator declaration. The signal reaches the warehouse instantly, without physical intermediaries.

Electronic kanban serves to eliminate the operational limits of paper kanban: lost cards, delayed signals, static sizing, lack of visibility, while keeping intact the lean logic that makes it effective. The result is a faster, more reliable and more governable supply flow.

LOG iN eKanban is the module of the LOG iN platform dedicated to electronic kanban. It monitors line-side consumption in real time, automatically generates refill signals, integrates natively with LOG iN WMS for picking execution and with LOG iN MOM for production visibility. It is not a standalone application: it is part of an integrated system covering warehouse, production, supply and maintenance.

The comparison between electronic kanban and paper kanban plays out on five concrete operational dimensions, not on a question of principle (the pull logic is identical), but on how that principle is executed in daily practice.

The replenishment signal. In paper kanban, it is a physical card that an operator must take from the line and bring to the warehouse. If the operator is busy, the signal waits. If the card falls or is lost, the signal is lost. In electronic kanban, the signal is automatic: it is generated by the system the instant the component level drops below the configured threshold. It does not depend on any human intervention.

The cycle speed. The paper kanban cycle depends on how fast people and cards move in the plant. The electronic kanban cycle depends on data speed: the signal reaches the WMS in real time, the picking mission starts immediately. The time between consumption and start of replenishment goes from minutes (or hours) to seconds.

Visibility. With paper kanban, to know how many signals are active you have to count the cards by physically checking. With electronic kanban, everything is visible on a dashboard: active signals, levels per kanban point, refills in progress, average cycle times, lines waiting.

Sizing. In paper kanban, the number of cards per component is calculated with a formula and stays fixed until the next recalculation, which often does not happen. In electronic kanban, reorder points are configurable rules that can be updated based on real consumption data, production mix, actual line pace.

Traceability. Paper kanban leaves no digital trace of the cycle: it does not record when the signal was generated, when the material left the warehouse, when it arrived line-side. Electronic kanban tracks every step with timestamp, operator, quantity, origin and destination. Every cycle is measurable, and the data feeds continuous improvement.

The conclusion is not that paper kanban does not work. It works, in contexts with limited mix, stable volumes and a few hundred codes. When complexity grows: more components, more lines, more variability, more pressure on times, the limits of the card become operational costs: line stoppages, inflated stock, management time spent chasing materials instead of governing flows.

Understanding how electronic kanban ERP integration works is one of the most frequent questions, and the answer depends on how the system is built.

A standalone electronic kanban must be integrated with three separate systems: the WMS (for replenishment execution), the MES (for consumption data from production) and the ERP (for material accounting). Three integrations, three connectors, three potential points of misalignment.

LOG iN eKanban works differently because it is part of the LOG iN platform. Integration with the WMS and the MOM is not a project: it is the starting condition. Here is how it works on each level.

With the WMS. LOG iN eKanban and LOG iN WMS share the same database. The refill signal reaches the WMS instantly and becomes a picking mission, with the same logic, the same interface and the same prioritization as the other picks. There are no exchange files, no connectors, no delays.

With the MOM. LOG iN eKanban accesses LOG iN MOM production data in real time: order progress, line pace, production mix. This allows the kanban to be more precise: reorder points can take into account the actual requirement generated by production in progress, not only static parameters.

With the ERP. The movements generated by the kanban cycle: stock picks, line-side deliveries, consumption per order, are transferred to the ERP through the standard bidirectional connectors of the LOG iN platform (SAP, Oracle, Microsoft Dynamics, AS/400). The ERP does not manage the kanban logic. It receives execution data: consumed materials, updated stock, allocated costs.

The result is an architecture where electronic kanban is a node of the plant’s information flow, not a peripheral application. The consumption data is born in production, generates a kanban signal, triggers a pick from the warehouse, updates the stock and returns to the ERP as an accounting movement: in a continuous cycle, without interruptions.

Line feeding, the process of supplying production lines with the materials needed for processing, is the operational context where electronic kanban produces the greatest value.

In a traditional system (without kanban or with paper kanban), feeding typically works in one of two ways: on forecast (the warehouse prepares materials based on the production plan released by the ERP, often hours in advance) or on manual request (the line operator signals the shortage and the warehouse reacts). Both methods have limits: the forecast does not account for priority changes, the manual request arrives late.

With LOG iN eKanban, feeding works in automated pull logic. The cycle is as follows.

The line operator works normally. When a component is consumed, the system detects the consumption: through operator scanning, the LOG iN MOM progress data, or the threshold declaration when the container reaches the minimum level.

LOG iN eKanban compares the current level with the reorder point. When the level drops below the threshold, it generates the refill signal. The signal reaches LOG iN WMS in the same instant: because they share the same database.

The WMS generates a picking mission: code, quantity, pick location, destination line. The warehouse operator receives the mission on the mobile device, picks, delivers line-side, confirms. The stock updates. The kanban point is replenished.

The whole cycle is tracked, measured, visible. The result for the line: materials arrive when they are needed, not when someone notices. Stoppages from missing components are reduced because the signal is automatic and the response time is measurable and improvable.

Understanding how to implement electronic kanban in the factory, and in how long, is one of the most concrete questions for those evaluating the move from card to digital.

Times depend on the scope: how many components, how many lines, how structured the existing physical kanban is (or whether you start from scratch).

As a reference, implementing LOG iN eKanban on a pilot scope (one production or assembly line with 50-150 components managed by kanban) typically takes 4-8 weeks from kick-off to go-live.

The analysis of supply flows takes 2-3 weeks. The components candidate for kanban, consumption points, cycle times between consumption and replenishment, current stock levels and the frequency of stoppages for missing material are mapped. If a physical kanban already exists, the parameters in use are analyzed and where they work and where not are identified. This phase is part of the AlfaProject.net Method.

Configuration takes 1-3 weeks. For each component, reorder point, refill quantity and priority are defined. For each line, the link with the WMS is configured: pick area, picking logic, delivery rules. If LOG iN WMS is already active, the kanban fits into the existing flow. If not, the two implementations can proceed in parallel.

Assisted go-live takes 1-2 weeks. The electronic kanban goes live on the pilot line. Operators see the system in action. The AlfaProject.net team monitors the cycles, measures the times, calibrates the parameters based on real data. The rules are refined in the first weeks: it is normal and expected.

The extension to other lines and components proceeds with progressively shorter times: the model is validated, the logic is the same, the configuration is incremental.

An important point: electronic kanban can be the first LOG iN module implemented in the plant. It is not necessary to already have the WMS or the MOM active. LOG iN eKanban works on its own too, and often represents the fastest and lowest-risk entry point into the platform. The value is immediate (fewer stoppages, less stock) and the scope is contained. It is the most pragmatic way to validate the LOG iN approach and then extend when results justify it.

The return on investment of electronic kanban is measured on four direct operational indicators.

Reduction of line stoppages from missing material. It is the easiest ROI item to quantify. Every stoppage has a calculable cost: plant cost, personnel cost, lost production, possible delivery delay. Electronic kanban reduces these stoppages by eliminating lost signals, manual delays and lack of visibility. In plants where stoppages from missing material represent 3-8% of available production time, the reduction is significant already in the first months.

Reduction of stock line-side and in the warehouse. Pull-logic supply based on real consumption allows reducing safety stock: fewer idle components, less tied-up capital, less occupied space. The impact is visible on working capital and measurable by the CFO.

Reduction of management time dedicated to emergency handling. Without electronic kanban, the logistics manager and the line manager spend a significant part of their time chasing missing materials, managing verbal reports, physically checking line-side levels. With electronic kanban, this time is freed up, because the system manages the flow automatically and makes exceptions visible before they become emergencies.

Data for continuous improvement. Every kanban cycle generates measurable data: cycle time, reaction time, components with higher refill frequency, bottlenecks in picking or delivery. This data feeds optimization interventions that produce cumulative value over time, a ROI that grows with the use of the system.

The AlfaProject.net Method estimates the kanban project payback before implementation, calculating for each scenario the investment, the payback times and the expected impact on indicators. After go-live, LOG iN eKanban returns the real data, and the comparison between forecasts and results is immediate.

For many manufacturing companies, electronic kanban is the module with the fastest payback of the entire LOG iN platform: contained investment, circumscribed scope, results visible in a few weeks. It is the most concrete way to demonstrate the value of the system before extending.
