A Production Progression Chart is a visual representation of the stages involved in production of an item from the base materials through the final product. A chart is based on the material used and items produced nominally per minute at ideal efficiency, but not accounting for upgrades in technology or buildings. By-products are included in the final output.
Basics
| Stage 1 | Stage 2 | |
|---|---|---|
Raw Materials
The Stage 1 column simply shows the input raw materials necessary to maintain full-rate production. By totaling the sum of all materials listed in the first column, the user can know how much supply is required to set up a full-rate production factory to produce the end product. In Example 1 above, it lists 60 Stone, so the user knows they need to maintain a supply of 60 stone per minute to their Stone Brick factory to maintain full-rate production.
Production Stages
Each further stage shows a production facility and resulting output. The quantities listed represent what can be achieved in one minute if the building receives all of the inputs listed in the previous stage. In Example 1 above, it shows that 1 Smelter can produce 60 Stone Bricks per minute if it is provided uninterrupted supply of 60 Stone per minute.
Final Stage
The right-most stage in the chart represents the final step in producing the end product. While it is functionally no different than other production stages, all of the listed products must be stored or distributed at this point to avoid clogging the production line.
Tips and Tricks
Scaling
Charts are generally listed at the lowest denomination which provides full efficiency. To scale up the quantity, a user can simply multiply all quantities of items and buildings by the appropriate integer to get the output they desire. In Example 1, simply multiply by 10, and a factory of 10 Smelters can produce 600 Stone Brick per minute if supplied with 600 Stone per minute.
Scaling down is more difficult, as it will generally lead to inefficiency and sometimes extra items at certain stages that will have to be disposed of to avoid clogging. In Example 1 above, cutting to 10% of the listed production can be done by only supplying 6 stone per minute to produce 6 stone bricks, but the single smelter cannot be reduced, and thus the smelter will spend most of the time not working.
