What is value stream management? In a plant it runs the physical flow of a product family; in software delivery it tracks work items. See how the two differ.

What is value stream management? It depends on who you ask. In a plant, it means running the physical flow of one product family from customer order to delivery, with one owner and a few shared measures. In software delivery, it usually means tracking work items from idea to release across an agile workflow and a DevOps pipeline. This article is for operational excellence managers who meet both meanings in search results, in vendor talks or in a meeting with the IT department, and who need to keep them apart.

Key points

• Value stream management in a plant runs the physical flow of one product family from order to delivery; in software delivery it tracks work items from idea to release.
• Both fields share lean origins: find the waiting, remove waste and shorten the time it takes value to reach the customer.
• Software tools use flow metrics such as flow time and flow efficiency, and DORA metrics such as change lead time and deployment frequency.
• A plant also deals with inventory, machines, changeovers and transport, which software flow metrics do not cover.
• When you read about value stream management, check first whether the source means manufacturing or DevOps.

What is value stream management in each field?

Both fields use the same two words for a similar idea: manage the whole flow that creates value for a customer, not just single steps.

In manufacturing, a value stream is the set of actions needed to bring a product from order to delivery. The Lean Enterprise Institute (LEI) describes a value stream as all the actions, value-creating and non-value-creating, needed to bring a product from concept to launch or from order to delivery. In a plant, the focus is the order-to-delivery stream of one product family. Managing it means a named owner, shared measures and a regular review.

In software delivery, a value stream is the path from an idea to working software in the hands of users. Planview describes the Flow Framework as "a structured, prescriptive approach to Value Stream Management in software delivery organizations". Planview is a software vendor, so read this as one vendor's view. The work items are features, defects, risks and technical debt, and the tooling connects the systems where teams track them.

The names match. The daily work does not.

Where does the idea come from?

The root is lean thinking. Toyota states that its production system aims to thoroughly eliminate waste and shorten lead times. Toyota names three kinds of problem to remove: muda (waste), mura (inconsistency) and muri (unreasonable demands on people and machines).

The LEI definition above already covers two kinds of stream: the operational value stream, from order to delivery, and the development value stream, from concept to launch. So the idea was never limited to the shop floor. Product development is a flow too, and software development is a type of product development.

That is why the two worlds still talk about the same things: waiting, handoffs, queues and silos. The difference lies in what moves through the stream.

How does a plant manage a value stream?

A plant manages a physical flow. In lean manufacturing, the typical elements are:

1. A product family. Products that share similar processing steps and equipment.
2. A value stream map. A chart of material and information flow, current and future state.
3. An owner. Often called the value stream manager, with backing from site management.
4. Shared measures. Lead time, inventory, delivery performance, first pass yield.
5. A weekly review. Actions, owners and dates.

What moves is material. It sits in a warehouse, waits in front of a machine or travels on a truck. It has a cost and takes up space, so inventory is a core measure. Changeovers, machine capacity and shift patterns shape the flow. Many plants also use lean management routines, such as daily meetings at the board, to keep the stream in view. The lean management topic page on M365.FM gives the wider picture.

How does software delivery manage a value stream?

Software delivery manages a flow of information. What moves is a work item: an idea, a ticket, a code change. It has no physical stock, but it still waits for a review, a test environment or a release slot.

Two sets of metrics are common:

• Flow metrics. The Flow Framework names flow velocity, flow time, flow efficiency, flow load and flow distribution. Planview's summary reads them as questions: is value delivery accelerating, is time-to-value getting shorter, is work waiting upstream, is demand outweighing capacity, and is investment split between new value and protection of existing value.
• DORA metrics. The DORA research programme groups its software delivery performance metrics into throughput (change lead time, deployment frequency, failed deployment recovery time) and instability (change fail rate, deployment rework rate).

A value stream management platform in this field connects ticket systems, code repositories and build pipelines so that teams can see how value flows from idea to release and deliver value to customers sooner. The result is a value stream map of the delivery process. Stakeholders from the business use it to see where work waits and to align on business value.

How do the two differ?

A side-by-side view helps:

• What flows. Plant: material and orders. Software: work items and code.
• Where it waits. Plant: in queues, buffers and stores. Software: in backlogs, reviews and environments.
• Core measures. Plant: lead time, inventory, delivery performance, yield. Software: flow time, flow efficiency, change lead time, deployment frequency.
• Typical owner. Plant: a value stream manager or operations lead. Software: a product or platform owner, or an IT leader.
• Data source. Plant: ERP, MES, shop floor data. Software: ticket and build systems.
• Typical aim. Plant: shorter lead time and steadier delivery. Software: faster, safer release of changes.

The shared part is the habit of looking at the whole flow and asking where it waits.

Which meaning applies to your search?

Use a quick test when you read a page or take a vendor call:

• If the text talks about tickets, pipelines, releases or sprints, it means software delivery and DevOps.
• If it talks about orders, machines, stock, shifts or takt (the pace set by customer demand), it means manufacturing.
• If it talks about both, ask which data the tool reads.

The abbreviation VSM adds to the confusion, because it can stand for mapping or for management. Tell your colleagues which meaning you use. IT leaders who run agile and DevOps ways of working will often mean the software one. The value stream manager in your plant means the physical one. Even the word bottleneck shifts: in a plant it is a machine or step that limits output, and in software it is often a review or test stage. Both fields still aim to eliminate waste and shorten the time value takes to reach the customer, so a good idea in one field is worth a look in the other.

Example: the same arithmetic in both worlds

This is an invented example. The numbers are not measured results, and the metric below is a simple planning measure, not a vendor's formula.

Take one measure that works in both fields: the share of elapsed time in which work is actively being done. Divide active time by total elapsed time.

• Plant. An order spends 10 working days in the stream. The team finds that the product is worked on for 1 day in total. The share is 1 divided by 10, which is 10 percent.
• Software. A feature takes 20 calendar days from start to release. Developers and testers work on it for 3 days in total. The share is 3 divided by 20, which is 15 percent.

In both cases, most of the time is waiting. The fix also looks alike: limit the work in progress, remove handoffs and release in smaller batches. What differs is where you look for the waiting: in a plant you walk the floor and count the pallets in queue; in software you read the timestamps in the ticket history.

Common mistakes

• Mixing up search results. A vendor page about DevOps value stream management will not help a plant.
• Importing software metrics into a plant. Deployment frequency means nothing for a machining cell.
• Importing plant metrics into software. Inventory turns do not apply to tickets in a backlog.
• Ignoring the shared lessons. Both sides can learn about limiting work in progress and shortening feedback loops.
• Buying a tool before defining the stream. In both fields, the owner and the measures come first.

How software can help

For a plant, the useful tools handle production data: orders, routings, capacity and inventory from the ERP system and the shop floor. They help you see the physical flow, not a ticket queue.

iFAKT is a Stuttgart-based consulting company and software specialist for Industry 4.0, founded in 2001. It helps manufacturers plan and optimize production and logistics processes and develops the Polaris software. Whichever vendor you consider, ask whether its data model fits physical flow.

Next step

What is value stream management for you? If you run a plant, it is the physical flow of one product family, and software-delivery articles are a side topic. Pick one product family this week and check whether it has an owner and three shared measures.
