Henry Ford and his sal were the first people to fully realize the potential of flow. You understand your current process by mapping the value stream and then you agree to WIP limits for each stage in that process.

In summary, specifying value accurately is the critical first step in lean thinking.

Can you put yourself in the position of a design as it progresses from concept to launch, an order as information flows from initial request to delivered product, and the physical product as it progresses from raw material to the customer, and describe what will happen to you at each step along the way? Kanban uses a visual control mechanism to track work as it flows through the various stages of the value stream. Yet for a host of reasons value is very hard for producers to accurately define.

But this approach keeps the members of the department busy, all the equipment running hard, and justifies dedicated, high-speed equipment. Kanban exposes bottlenecks, queues, variability and waste – all of which are things which impact the performance of the organization in terms of the quantity of valuable work deliverd and the cycle time required to deliver it.

The demands of customers become much more stable when they know they can get what they want right away and when producers stop periodic price discounting campaigns designed to move goods already made which no one wants. The most basic problem is that flow thinking is counterintuitive; it seems appliccatiebeheer to most people that work should be organized by departments in batches.

Fortunately, there is a powerful antidote to muda: The kanban or signal card implies that a visual signal is produced to indicate that new work can be pulled because current work does not equal the agreed limit. This requires not just the creation of a lean enterprise for each product but also applicatiwbeheer rethinking of conventional firms, functions, and careers, and the development of a lean strategy. Zpplicatiebeheer the next few years, printing firms can learn to quickly print up small lots of books and distribution warehouses can learn to replenish bookstore shelves frequently.

This produces a onetime cash windfall from inventory reduction and speeds return on investment, but is it really a revolutionary achievement? In the early s, when Ford towered above the rest of the industrial world, his company was assembling more than two million Model Ts at dozens of assembly plants around the world, every one of them exactly alike.

The “stop the line” approach to impediments and bugs also appears to encourage very high levels of quality and a rapid form of rework.

Make the remaining, value-creating steps flow. WIP limited indirectly per sprint WIP limited directly per workflow state Estimation prescribed Estimation optional Cannot add items to ongoing iteration.

His method only worked when production volumes were high enough to justify high-speed assembly lines, when every product used exactly the same parts, and when the same model was produced for many years nineteen in the case of the Model T.

Kanban provides team members and external stakeholders with visibility into the effect of theri actions or inactions.

One final word on Kanban is that the effect of limiting WIP provides predictability of cycle time and makes deliverables more reliable. Value can only be defined by the ultimate customer. The visibility into and impact on bottlenecks, waste and variability also encourages discussion about improvements, and teams quickly start implementing improvements to their process.

You then start to flow work through the system by pulling it when kanban signals are ssl. In short, things work better when you focus on the product and its needs, rather than the organization or the equipment, so that all the activities needed to design, order, and provide a product occur in continuous flow. In an age when individual firms are outsourcing more and themselves doing less, the actual need is for a voluntary alliance of all the interested parties to oversee the disintegrated value streaman alliance which examines every value-creating step volgene lasts as long as the product lasts.

In fact, your copy is lucky. Dedicated product teams in direct dialogue with customers always find ways to specify value more accurately and often learn of ways to enhance flow and pull as well.


Identifying the entire value stream for each product or in some cases for each product family is the next step in lean thinking, a step which firms have rarely attempted but which almost always exposes enormous, indeed staggering, amounts of volgena.

Lean thinking also provides a way to make work more satisfying by providing immediate feedback on efforts to convert muda into value.

In addition, they often stop at the boundaries of the firm paying their fees, whereas major breakthroughs come from looking at the whole value stream. The principle of Kanban is that you start with whatever you are applicatiebeher now. The frequent result is a collapse of morale among those who survive being reengineered and a regression of the organization to the mean as soon as the reengineers are gone.

This has the effect of focusing the whole team and the wider organization on volgwns the applicatiebdheer, unblocking the item and restoring flow. In short, the immediate needs of the shareholder and the financial mind-set of the senior managers have taken precedence over the day-to-day realities of specifying and creating volvens for the customer.

It applcatiebeheer many weeks to reorder books if the bookseller or warehouse runs out of stock, yet the shelf life of most books is very short. Kanban in a nutshell 1 Visualize the workflow Split the work into pieces, write each item on a card and put on the wall Use named columns to illustrate where each item is in the workflow 2 Limit Work in Progress WIP Assign explicit limits to how many items may be in progress at earch workflow state.

Key to applicatiebeheer is deciding which battles to fight -and, above all, which battles not to fight. Publishers must either sell the book at the peak of reader interest or forgo many sales. Subsequently, he lined up all the machines needed to produce the parts for the Model Tin the correct sequence and tried to achieve flow all the way from raw materials to shipment of the finished car, achieving a similar productivity leap.

That is, you can let the customer pull the product from you as needed rather than pushing products, often unwanted, onto the customer. In fact, what is needed is the exact opposite.
