Monitor in real-time the workers in the production lines.
The system tracks assembly execution on the production line in real-time. It monitors production times and delays. The manager sees the work progress rate in real-time.

Backgronud:

The next stage in the production process is assembly on the production line by the workers.
Currently, at this stage, there are quite a few malfunctions and errors in assemblies due to incorrect documentation or poor explanations.
This also leads to significant parts wear, human errors (which can sometimes cost lives),
and time waste until the assembly is properly completed.

The production line manager has many tasks to perform and pay attention to simultaneously.
He needs to ensure the work progress rate is good and that delivery times are met, manage the workers simultaneously, and provide support when a worker gets stuck with assembly.

Line Manager's Challenges:

1. To manage the workers, ensuring everyone is progressing with their tasks.
2. To notice when a worker gets stuck and doesn't know how to proceed with their task.
3. To verify that each worker has all the necessary parts and tools for assembly.
4. To schedule coming lines do to due dates.

The Solution:

Since the products are connected through the same system, the visual documentation by steps, initially performed by the documenters, is transferred directly to the systems on the production line and displayed to workers on digital screens. This way, workers on the production line barely need to know how to read and can understand the assembly stages from the detailed images and the breakdown of assembly into
sub-stages. After each stage is properly completed, the system displays the next stage. This solution allows the line manager to know which assembly stage each worker is at and whether they are stuck and need help.
