JAM Group — PO Automation

JAM Group is a Belgian fibre and telecom contractor that works on Proximus projects. I automated the checks, calculations and PO preparation that had previously been handled by more than five people.

The problem

What needed to change

The process involved more than five people checking source data, calculating amounts and copying the results into POs. Manual entry took time and caused both data-entry and calculation errors.

What I built

What the system does

  • Documented each step from the source data to the PO.
  • Built the validation and calculation rules into one automated system.
  • Built the system to send data to the PO step automatically after the checks and calculations pass.
  • Deployed the system for day-to-day use.

Key decisions

Why it works this way

  • Stored the calculation rules in one place so every record is handled the same way.
  • Checked the data before it reached the PO step.
  • Removed repeated data entry between people and steps.

Workflow
