Thirty Years of Word, Excel and Email: Why Digitising the Packet Did Not Lift the Mining Back Office
The packet went digital. The route did not.
Windows 95 and Microsoft Office shipped in August 1995 — thirty-one years ago. That is the moment the paper files in a mining supplier's office became a Word file, a spreadsheet and, before long, an email attachment. The paper ledger became an Excel workbook. The typed letter became a Word doc. The fax and the in-tray became Outlook. It was a real gain: sending information got almost free.
But look at what actually happens on a Friday in a $10M–$50M WA supplier. A mobilisation pack, a timesheet, a purchase order and a tender still hop from desk to desk as attachments, and a person at each desk opens the file, does something to it, and hands it on. The document is digital. The job — routing it between the desks — is exactly the job it was in 1995. We digitised the packet. We never touched the route.
Why the productivity never showed up
Economists have a name for this. In 1987 Robert Solow quipped that “you can see the computer age everywhere but in the productivity statistics”, and Erik Brynjolfsson later showed why: a new technology only pays once the business process around it is redesigned. Buying the computers is the easy part; the gains wait on the harder, unglamorous work of changing how the work flows. Firms that only bought the tool got a faster keyboard, not a faster business.
Office made sending cheap. It left deciding, assembling and handing on with the same person at the same desk. That is why two things a mining supplier owner says can both be true at once: “we are completely digital” and “we are still hiring another admin every time we win a site.” The tool changed; the operating model did not.
It is the national story in miniature: ICT added about 0.3 points to Australia's annual growth in the late 1990s, yet productivity growth in the decade to 2020 was the slowest in sixty years. We wrote about where the AI dividend actually lands in Australia vs the US on Economic Complexity.
The job ad is the tell
You can read the whole problem off a Seek ad. Open any WA site-administrator posting in 2026 and it asks for “proficiency in Microsoft Office — Excel, Word, Outlook” right next to INX, Pronto or SAP. One person is expected to sit between systems that do not talk to each other and move the data by hand.
Your ad says
- “Proficiency in Microsoft Office (Excel, Word, Outlook)”
- “Update rosters, process production data, prepare purchase orders”
- “Compile daily, weekly and monthly reports”
What that job actually is
- Be the human router between four systems that do not talk.
- Re-key the same number into Grid, Excel and Xero.
- Rebuild the report by hand every time a Tier 1 asks.
Office proficiency is the skill you advertise when the process still lives in a person. When the routing moves into the system, you stop hiring for it.
Four desks, four Office hops
The same pattern runs across every function a supplier already operates. Each one is a file being carried between desks by a person — the exact work Office was supposed to have solved.
People & Workforce
Grid → Excel → Outlook → Xero. The coordinator exports the roster, calculates the MA000011 penalties by hand, emails the workbook to payroll, then re-keys it into Xero — 8 hours every fortnight.
Safety & Compliance
A Word SWMS emailed around, an Excel training matrix that is always a fortnight stale, and the audit pack rebuilt in the donga the night before a WorkSafe (LGIRS) inspection or a BHP audit.
Operations & Maintenance
An Excel PO register nobody trusts, a Word purchase request sitting three days in a Newman inbox, and a month-end match done by hand against the Xero feed.
Commercial & Finance
An Excel tender tracker, a Word proposal copy-pasted from the last one, and an Outlook folder of invoices the owner chases personally on a Friday afternoon.

A faster keyboard is not a faster business
The obvious next move is to bolt AI onto the stack you already have — Microsoft 365 Copilot, or ChatGPT pasted into a Word doc. It helps, but it is the same operating model with a quicker typist. The file still hops between desks; one person still assembles it. To change the maths, the desk has to run in the system.
A faster keyboard (Copilot in the same stack)
- Microsoft 365 Copilot, or ChatGPT pasted into a Word doc, helps the coordinator draft the same email a little faster.
- The file still hops desk-to-desk as an attachment, and one person still assembles it and hands it on.
- You are more digital than ever and still hiring the next admin when you win the next site.
The desk runs in the system (Admin Runs Itself)
- The mobilisation, the compliance pack, the timesheet, the tender and the invoice are produced and routed by the agents.
- No workbook to email, no re-keying between Grid, Excel and Xero — one live record instead of a chain of attachments.
- The coordinator stops being the bus. Win the next site and the work goes up; the back office does not.
This is the copilot-vs-system distinction we drew in From Hierarchy to Intelligence, now applied to the tool the industry has actually run on for thirty years.
What Admin Runs Itself changes
For the first time, the routing itself moves into the system. The agents process and route information between the four desks — mobilisation, compliance pack, MA000011 timesheet, tender, invoice — so the coordinator is no longer the bus every job has to ride. The monotonous, data-intensive re-keying goes to the agents; the people move to the edge, close to the customer, where the work actually wins and keeps contracts and grows the brand.

The upside
Add the next site without the next hire — the back office stops scaling with the work
The structural difference
Not a faster keyboard inside the old model — the routing between desks finally leaves the person and lives in the system
Office digitised the document. DrilLedger runs the desk.

Frequently Asked Questions
Did not Office already digitise the back office?
It digitised the document, not the process. Windows 95 and Office turned the paper ledger into a spreadsheet, the typed letter into a Word file and the fax into an Outlook attachment — a genuine gain in how cheaply information could be sent. But the coordination work stayed with a person: someone still exports Grid to Excel, calculates the penalties, emails the workbook and types it into Xero. Transmission got cheap; routing, deciding and assembling did not. That is why a supplier can be fully paperless and still hiring the next admin every time it wins a site.
Is this just Microsoft Copilot for mining?
No. Copilot — and ChatGPT pasted into a Word doc — is a faster keyboard inside the same desk. It helps one person work the same process a little quicker, so the file still hops between Grid, Excel, Outlook and Xero and one person still assembles it. DrilLedger runs the desk itself: the FIFO mobilisation, the WorkSafe (LGIRS) audit pack, the MA000011 timesheet, the tender and the invoice are produced and routed by the agents, not typed by a person with AI assistance. That is the difference between making the bottleneck a little faster and removing it.
Why do our Seek ads still list Excel, Word and Outlook?
Because the role is still to be the human router between systems that do not talk. Look at any WA site-administrator ad in 2026 — it asks for Microsoft Office proficiency alongside INX, Pronto or SAP, because one person sits in the middle updating rosters, processing production data, preparing purchase orders and compiling reports. Office proficiency is the skill you advertise when the process lives in a person rather than the system. When the routing moves into the system, you stop hiring for it.
Will the office team still have a job?
Yes — a better one. This is not a headcount-cut story. The monotonous, data-intensive routing — the part that caps how much work you can take on — moves into the system. Your people move to the edge: the BHP superintendent, the crew on the tools, the judgement call on a tricky tender, the relationships that win and keep contracts. You stop needing the next admin hire to grow, and the people you have do the work that actually grows the brand and the business.
