The diagram illustrates the processes involved in the production of fish pies. The main ingredients used in this product are fresh salmon, peas, sauce and chopped potatoes, and they are prepared separately in different chains

The potatoes are delivered in trucks to the factory and this may take up to one month. The potatoes are then cleaned thoroughly, pealed and sliced into small pieces. Afterward, the slices are boiled and left outside to cool out. The final process is to store the prepared potatoes, waiting for other ingredients to be finished.

The fresh salmon preparation needs more effort and labour work. It is also delivered to the manufactory within 12 hours. After being spiced with lemon juice and salt, salmon is then steamed in an oven, getting ready to have the skins and bones eliminated by labour workers. Before being packed with other ingredients, it is then scrutinized again in order to ensure the quality of the output.

The potatoes, steamed salmon, along with the simply prepared sauce and peas are wrapped together into a complete product. Finally, it is frozen and stored, ready to be dispatched.
