Lean Tips for Holiday Pie Making
Every Thanksgiving, Accelerate’s Marcie Hopkins makes not just one, but multiple pies to enjoy. To maximize efficiency, she teamed up with Farmington manager Matt Sanford to design the perfect process. And—of course—there’s a health care application as well.

Why single piece flow or small batches are better


seems counterintuitive—but producing things one at a time, or in small batches, is a more efficient mode of production.

Batching is defined as performing tasks or creating things in a large quantity all at once. You must wait for the batch to accumulate, which produces greater amounts of inventory (and more waste).

Single piece flow, or doing things in small batches, can be more effective. Single piece flow allows you to process one part at a time using small batches. Setup, equipment, and supplies determine the size of the batch. When properly applied, the result of single piece flow is less waste and more flexibility in the process.

Single piece flow in health care

Here’s a simple version of single piece flow: a provider completes patient notes in between each visit, rather than waiting to tackle them all at once at the end of clinic. This process is more efficient, and the output is better: writing notes while you’re fresh rather than waiting (and potentially forgetting key pieces of information) is a safety best practice.

Single piece flow for pie making

Marcie uses a single pie flow to prepare her crust.

How to set up:

  1. Have each ingredient on hand—do not put away until all crusts are made.
  2. Use dedicated measuring devices for each ingredient.
  3. Use the same bowl for each crust, you don’t need to clean in between.
  4. If a second person is helping, have them complete a step further down the line. For example, the first person can measure and mix one pie crust while the second person can roll out the pie crust. While the second person rolls out the crust, the first person can make another pie crust.

Benefits of single piece flow

In General In Pie Making
1. Reduce time in queues n/a
2. Can reduce turnaround times n/a
3. Improves production rate n/a
4. Catches errors earlier If your crust isn’t working, you can resolve the issue before you’ve made all of them
5. Less cash tied up in work in process and finished goods If you make 6 crusts but only end up using 3, you won’t have all that extra
6. Less space and equipment needed to handle large loads of equipment You won’t need an industrial mixer or oven
7. Less opportunity to damage WIP Different stages of pies sitting around
8. Greater processing flexibility You can more easily make different kinds of pies

Whether you plan to spend this holiday at work or at home, single piece can help you add a little flow as you go.
