In a SIPOC diagram, the Inputs column lists the primary inputs needed by the processes listed in the Process column. Here are a few Input examples –

  • Passenger information for an airport check-in process.
  • Raw materials for a manufacturing process.
  • Server uptime data for a monthly IT performance report.
  • An email list for a marketing campaign

Keeping the Inputs column consolidated can be a challenge, and it’s best to group similar items together to prevent a cluttered document. ┬áIn the example below, the material suppliers for a motor manufacturing process are grouped into one cell, which keeps the number of inputs in the document from getting out of hand.
