Live! Value Stream (Sept.2026)

Stock Data

Inventory Accumulated stock of materials waiting for downstream processing, often resulting in a Push Flow. Blocked Stock that cannot be used due to capacity constraints, quality issues, or missing downstream availability. Controlled Stock managed through predefined limits or other systems based on forecast, to ensure availability while avoiding overproduction.

Just In Time A pull-based material flow in which the upstream process supplies the exact quantity of materials required by the downstream process, precisely when needed and in frequent, short cycles. Staging Area Area for preparing finished goods for shipping (or external transport). Coverage: 1 loading unit (e.g., 1 truck or container)

SizeTotal quantity of materials held at a given time within this stock.

VariantsNumber of significantly different product types in the stock.

Safety BufferExtra inventory not used during the normal workflow.
Its presence increases the lead time displayed on TimeLines.

Parts per ProductSituation where more than one unit of the same part is held in this stock to assemble a single finished product.

Main Transport ModePrimary method used to transfer materials in and out of the stock, such as by forklift, milkrun, or manual handling.

Pre-Stock Transport ModeSpecific method used to move materials into the stock from the upstream process.

Post-Stock Transport ModeSpecific method used to move materials out of the stock to the downstream process.

Supermarket Data

Current AmountActual inventory level currently available/checked on the shopfloor.
This is the value shown as waiting time in the TimeLine.

Max. LevelMaximum inventory level allowed to prevent overproduction.
Once this level is reached, upstream process must stop or react consequently.

Min. LevelMinimum inventory level that triggers a signal to replenish.
When this level is reached, upstream process must resume to avoid shortages.

VariantsNumber of significantly different product types in the supermarket.
Please note that usually each variant would require different cards and a dedicated location.

Safety BufferExtra inventory added to the supermarket calculation, not used during the normal workflow.
Its presence increases the lead time displayed on TimeLines.

Parts per ProductSituation where more than one unit of the same part is withdrawn from the supermarket to assemble a single finished product. Withdrawal and replenishment quantities must reflect this multiplier.

Main Transport ModePrimary method used to transfer materials in and out of the supermarket, such as by forklift, milkrun, or manual handling.

Pre-Stock Transport ModeSpecific method used to move materials into the supermarket from the upstream process.

Post-Stock Transport ModeSpecific method used to move materials out of the supermarket to the downstream process.

Draw Withdrawal symbol?Draws an open-loop arrow, that represents the movement of materials from the supermarket to its downstream process using a pull system.

Draw material flow Pull arrows?Shows the physical direction of material movement into and out of the supermarket, drawn as inward and outward arrows to clarify flow. They are usually used instead of the Withdrawal Symbol

Draw Withdrawal kanban signal?Draws the kanban card (and its arrow) used to indicate what, and how much to withdraw to supply the downstream process.
You can write a number in the box on the right to indicate the num. of cards/products to be withdrawn.

Draw Production kanban signal?Draws the kanban card (and its arrow) which triggers upstream process to produce and replenish items taken from the supermarket.
You can write a number in the box on the right to indicate the num. of cards/products to be produced.

Leveling at Replenishment?Draws the icon used to specify a signal sent to trigger production based on averaged demand, supporting leveled flow instead of reacting to each individual withdrawal.

Sequence Data

JIS - Just In Sequence Method where parts are delivered in the exact order they are needed by the downstream process, which controls both timing and sequence. FIFO - First In First Out Method where parts are used in the same order they arrive. The upstream process determines the production flow.

OBF - One Batch Flow Specific type of FIFO where parts are moved and processed in fixed-size batches through each production step. OCF - One Container Fl Flow method where one container of parts is transferred at a time between processes. Similar to FIFO, the upstream process controls it. OPF - One Piece Flow Method where parts move individually and continuously from one process to the next without waiting, to maximize flow efficiency.

Max.SizePredefined limit on the number of parts moving through this flow to ensure stability while avoiding disruptions.

VariantsNumber of significantly different product types in the sequence.

Safety BufferExtra inventory not used during the normal workflow.
Its presence increases the lead time displayed on TimeLines.

Parts per ProductNumber of parts in the sequence required to produce one finished product.

Transport ModeMethod used to move materials along the sequence, such as forklift, milkrun, or manual handling.

DemandAverage number of Finished Products this Customer requests within a given period.

Customer TaktTimeTime required to produce every Product, ensuring this Customer Demand, calculated by dividing available Production Time by the number of requested units.

SeasonalityVariations in Customer Demand, that occur periodically due to diverse factors, measured as the percentage deviation from the average value.

VariantsNumber of significantly different versions of the same product that the Customer demands.

Num.DeliveriesTotal count of deliveries made to the Customer within a given period.

Process Data

NameTry to choose a clear text that describes the action performed and the piece you transform.
For example: Doors Painting

Cycle TimeTime that elapses between one processed piece and the next

Process TimeTime needed for a piece to go through the entire Process

Machine TimePart of Process Time in which Machine Work is performed

Worker TimePart of Process Time in which Manual Work is performed

POTPlanned Operation Time, is the previously scheduled net activity time for this Process.
For example 480 min/shift - 30 min planned breaks = 450 mins of POT

Shifts per dayNumber of shifts in which this Process is working

Process TaktTime...

Parallel StationsNumber of lines, stations, machines... that work in parallel performing this same Process, with the same Cycle Time, Process Time, etc., and the aim of multiplying the number of processed pieces.
Please note this data can affect TimeLine and Bottleneck calculation

OEEOverall Equipment Effectiveness, is a measure of how well a manufacturing operation is done compared to its full potential, during the period when it is scheduled to run.
Please note this data can affect TimeLine and Bottleneck calculation

COTChange Over Time, average time required by the Process to change between different Variants

Scrap RatePercentage of pieces that are discarded due to defects, damage, or failure to meet quality standards

Similarly, if a piece is only needed in 20% of the finished products, we would type 0.2 here

Lot SizeMinimum quantity in which we group the produced pieces, due to restrictions on the size of their containers, their means of transport, or for other reasons

Min. Order SizeMinimum quantity of pieces that the Process can produce, either due to restrictions on the raw materials or resources it uses, or for other reasons

Num. WorkersWorkers needed to run the Process.
Please note that if there are several Parallel Stations, this number will refer to only one of them

% Dedicated UsePercentage of POT this Process spends on the mapped product.
A value below 100% is emphasized by showing a slightly different symbol and can be used in TimeLine and Bottleneck calculation

% Value AddedEstimated percentage of the Process Time in which we add real value to the product our Customer demands.
Please note this data can be used in the TimeLine look and calculation

Is Bottleneck?A Bottleneck is any Process unable to produce as fast as the customer's pace (TaktTime) demands
The Auto option makes the app to perform all needed calculations and display or hide its symbol
