Why a spreadsheet stops working as your production tracker

A spreadsheet is free, instant, and infinitely flexible. For a handful of jobs and one person tracking them, it's genuinely the right tool, no setup, no learning curve. The trouble is not that spreadsheets are bad. It's that production management is a different shape of problem than a spreadsheet is built for, and the mismatch only shows up once you grow past a certain size.

The failures are predictable. First, status as a column means you can never see the whole pipeline at a glance, only by filtering and squinting. Second, concurrent edits corrupt or overwrite each other the moment two people touch the same sheet. Third, no history, you cannot answer "how long did this job sit in painting?" because the cell only holds the current value, not how it changed. Fourth, no limits, nothing stops twenty jobs from piling into one stage, which is exactly the bottleneck a spreadsheet hides — WIP limits don't even exist as a concept in a grid.

A board makes the pipeline the primary view: every job is a card, every stage is a column, and the shape of your work is visible the instant you open it. Moving a card is the status update, so the record can't drift from reality. Each move is timestamped, so per-stage durations and bottlenecks fall out automatically. And because it's built for many hands, two people updating at once is the normal case, not a corruption risk.

The honest signal is friction, not size. The moment you find yourself maintaining a colour-coded legend, locking the sheet so people stop breaking it, or rebuilding the same pivot every Monday to answer "where are we?", the spreadsheet has become the work instead of tracking it. That's the cue to move to Production Board, where the pipeline view, the history and the limits come built in instead of hand-rolled.
