7 Common Problems With Excel Training Matrices

A spreadsheet can still be the right tool for a tiny team with one careful owner. These problems show up when the workforce grows, sites multiply, or more than one person edits the sheet. None of them mean Excel is “illegal” — they mean the matrix stops being trustworthy.

1. Version chaos

The living file becomes Training_Matrix_FINAL_v3_JM_edits.xlsx on a shared drive, a copy in WhatsApp, and another on someone’s laptop. Supervisors check different versions. Renewals get entered in one and not the others. The grid still looks tidy — it is just not the same grid.

2. Silent expiries

Excel does not email you when a date passes. Conditional formatting helps only if someone opens the right file and looks. Cards and courses lapse mid-project while the sheet still shows last month’s colours.

3. Blank cells that mean nothing clear

Blank often means “missing”, “not required”, “we never checked”, or “probably fine”. Without a hard rule (blank = no record; N/A = not assigned), gaps hide until a client or gate asks for proof.

4. Dates stored as text

“Aug 26”, “March”, or “valid” break sorting and TODAY()-based rules. Real date values (for example DD/MM/YYYY) are the minimum for any matrix you intend to filter by soonest expiry.

5. Evidence living somewhere else

A date without a certificate or card image is weak when someone asks for an evidence pack. Filenames like scan0042.pdf in a shared “certs” folder do not survive a short-notice audit. The matrix and the files need a clear link.

6. Role and requirement drift

Someone changes role, a customer adds a site rule, or a new plant type appears — and columns stay frozen. The matrix still answers yesterday’s question. Requirements vary by role, activity, customer and site; the sheet has to be updated when assignments change.

7. No single owner

When “everyone updates it”, nobody does. Leavers stay on the roster. New starters never get a row. Expiry reviews slip. Ownership is an operating decision, not a formula.

When Excel is still fine

Under roughly ten workers, one owner, and a weekly review habit, Excel can work. The tipping point is usually multiple editors, subcontractors on the same view, or more dates than a weekly sort can cover honestly.

If you recognise three or more of these problems, upload the matrix you already have into training matrix software so status is calculated from today and reminders fire before renewals are due — without rebuilding the idea from scratch.
