# Assets
Assets are the collection of all work resources within an organisation. They are divided into the following categories:
# Tools
Tools: these are individual assets or tools that are deployed as needed, for example during maintenance work. Examples include ladders, pressure washers and hand tools.
# Devices
Devices: these are individual assets or products that are deployed permanently, such as fixed installations or machines. Parts of devices or installations can be managed separately and linked to a parent device in a tree structure.
# Articles
Articles: these are goods or services that are created or consumed in production processes. Examples are batteries, lubricating oil, water, or salt for refilling.
# Maintenance and warranty dates
For every device (asset) you can display important dates:
- Last maintenance: this is derived dynamically from the linked workflows. Per asset type you link a job type/workflow (e.g. using a "maintenance" label), so that the last execution date is taken over automatically. This field only appears when a workflow is linked.
- Installation date of the device.
- Warranty expiry date.
This way you no longer have to keep track of these dates manually, and you can see the maintenance history per asset at a glance.
