Below are the 3 stages of human factors I considered when completing my final year project.

Above is the first of the offline of the product syntax stages where the product is unpacked placed in the fireplace and is ready to be used.

Here the product is in use, (online) the ash falls through the grate and into the collection area.

The final “offline” stage is the user opening the fireplace and removing the collected ash and moving it to the bin.
