Learn to spot the difference with fulfillment and streaming. - Author: Sathya Narayanan - Tags: Alloconomy, Foundations, Activity-Based Costing, #series-detail Foundations · Mental model 2 ## Follow the work: ten simple ideas 1. Start here[The ten-idea cheat sheet](https://abundance.alloconomy.com/alloconomy/activity-based-costing/)A simple map of the work behind a price. 2. Idea 1[Costs follow work](https://abundance.alloconomy.com/alloconomy/abc-01-costs-follow-work/)Connect a customer promise to the tasks behind it. 3. Idea 2**Different levels of work**Current essayFind what makes an activity repeat. 4. Idea 3[Averages hide differences](https://abundance.alloconomy.com/alloconomy/abc-03-averages-hide-differences/)Compare equal shares with actual use of shared work. 5. Idea 4[Choose a useful measure](https://abundance.alloconomy.com/alloconomy/abc-04-count-the-work/)Match the measure to the activity it explains. 6. Idea 5[Available and used capacity](https://abundance.alloconomy.com/alloconomy/abc-05-ready-and-used/)Separate available time from time used by customers. 7. Idea 6[Extra steps add up](https://abundance.alloconomy.com/alloconomy/abc-06-extra-steps/)Build a job from its ordinary steps and additions. 8. Idea 7[Follow the customer journey](https://abundance.alloconomy.com/alloconomy/abc-07-whole-customer-journey/)Look at the help before and after a sale. 9. Idea 8[Ask what actually changes](https://abundance.alloconomy.com/alloconomy/abc-08-what-actually-changes/)Compare the money that changes under a decision. 10.

Idea 10[Keep the model useful](https://abundance.alloconomy.com/alloconomy/abc-10-keep-it-useful/)Measure enough to support the decision, then improve it. ## Ten cards, one setup Maya and Mayan print ten invitation cards. Before printing, they put the paper in place and check the design. Then they print each card. Printing repeats ten times. Preparing the printer happens once for the group. The group is called a **batch**. If they split the same ten cards into five separate batches, they still print ten cards. But they prepare the printer five times. Same number of cards; more preparation. [![EACH ITEM: Pack a parcel: 1 more parcel → 1 more pack; EACH GROUP: Prepare a batch: 1 more batch → 1 more setup; WHOLE SERVICE: Keep the site running: Supports many orders](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/2026/10/02-abc-02-different-levels.png)](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/2026/10/02-abc-02-different-levels.png?ref=abundance.alloconomy.com) More items do not make every activity repeat. Numerical examples are illustrative; actual business economics require case-by-case analysis.

Some happens **for each batch**, such as preparing a machine for a group of items. Some supports **the whole service**, such as keeping a building open. We can also have work for a product type or a customer, such as creating one design or setting up one customer account. The habit is the same: ask what makes the activity happen again. Suppose preparing a printer takes 6 minutes. One batch needs 6 preparation minutes. Five batches need **5 × 6 = 30 minutes**. If each card takes 1 minute to print, printing still needs 10 minutes in either case. Total work rises from **16 to 40 minutes** because preparation repeats more often. These are teaching numbers. ## Apply it to Walmart Fulfillment Services Walmart Fulfillment Services describes storage, shipping, returns and customer service for sellers. [Walmart's overview](https://marketplace.walmart.com/walmart-fulfillment-services/?ref=abundance.alloconomy.com). Imagine a simple fulfillment centre. A worker picks and packs each order. Receiving a truckload is work for a group of goods. Setting up information for a new product is work for that product type. Keeping the building open supports the centre as a whole. If ten small deliveries replace one large delivery, receiving work may rise even when the total number of products stays the same. A model that counts only products can miss this. That observation does not tell us to make every shipment enormous. It tells us where to look when asking why the work changed. ## Apply it to YouTube and Netflix For a YouTube creator, recording a video is work for that video. A thousand extra views do not make the creator record it a thousand more times. For YouTube, delivering those extra views creates platform activity. Those are different businesses and different jobs. For Netflix, making a title available and delivering a viewing session are also different activities. We should not assume that every cost repeats whenever someone presses play. Nor should we assume that all extra viewing is free. First identify the activity and its level. ## Try it A bakery bakes 100 cookies in one batch, then considers baking the same 100 cookies in five batches. Which activity probably repeats more often: mixing a batch or putting one cookie in a bag? **Answer:** batch preparation repeats more often; bagging still follows the number of cookies. **Carry this idea:** a cost divided by ten items is not necessarily a cost caused ten separate times. ## Source [OpenStax's ABC chapter](https://openstax.org/books/principles-managerial-accounting/pages/6-3-calculate-activity-based-product-costs?ref=abundance.alloconomy.com) explains unit, batch, product and facility levels.
