small-batch approach

is an approach that produces a finished product every few seconds, and is thus, nimble, whereas large-batch approaches is not amenable to changes during process.

All these issues are visible in a process as simple as stuffing envelopes, but they are of real and much greater consequence in the work of every company, large or small. The small-batch approach produces a finished product every few seconds, whereas the largebatch approach must deliver all the products at once, at the end. Imagine what this might look like if the time horizon was hours, days, or weeks. What if it turns out that the customers have decided they don't want the product' Which process would allow a company to find this out sooner'

is difficult because there is a constant desire to fix one more bug or add one more feature.

Eventually, one batch will become the highest-priority project, a 'bet the company' new version of the product, because the company has taken such a long time since the last release. But now the managers are incentivized to increase batch size rather than ship the product. In light of how long the product has been in development, why not fix one more bug or add one more feature' Who really wants to be the manager who risked the success of this huge release by failing to address a potentially critical flaw'

is an approach that enables companies to serve its smaller, more fragmented markets and still compete with the mass producers.

 makes factories more efficient. In contrast, in the lean startup the goal is not to produce more sufficiently. It is to as quickly as possible learn how to build a sustainable business.

Toyota discovered that small batches made their factories more efficient. In contrast, in the Lean Startup the goal is not to produce more sufficiently. It is to as quickly as possible learn how to build a sustainable business.

1s 2esson is that the ability to learn faster from customers is the essential competitive advantage that startups must possess.

The essential lesson is not that everyone should be shipping fifty times per day but that by reducing batch size, we can get through the Build-Measure-Learn feedback loop more quickly than our competitors can. The ability to learn faster from customers is the essential competitive advantage that startups must possess.

is grounded in the idea that quality problems can be identified much sooner.

The biggest advantage of working in small batches is that quality problems can be identified much sooner. This is the origin of Toyota's famous andon cord, which allows any worker to ask for help as soon as they notice any problem, such as a defect in a physical part, stopping the entire production line if it cannot be corrected immediately. This is another very counterintuitive practice. An assembly line works best when it is functioning smoothly, rolling car after car off the end of the line. The andon cord can interrupt this careful flow as the line is halted repeatedly. However, the benefits of finding and fixing problems faster outweigh this cost.

is the paradoxical idea that it is actually faster, for example to fold then stuff one hundred envelopes than to first fold one hundred letters and then stuff the envelopes.

The one envelope at a time approach is called 'single-piece flow' in lean manufacturing. It works because of the surprising power of small batches. When we do work that proceeds in stages, the 'batch size' refers to how much work moves from one stage to the next at a time. For example, if we were stuffing one hundred envelopes, the intuitive way to do it folding one hundred letters at a time would have a batch size of one hundred. Single-piece flow is so named because it has a batch size of one.
