A water utility sends an enquiry to upgrade six pumping stations running on an older controller platform. The firm has one engineer who knows that platform well and has commissioned water plants before. He is three weeks into a steel plant job and cannot be spared. The owner can quote a date the team will miss, or let the enquiry go to a rival. Both choices cost more than the engineer's salary.
Our automation company HR page names this as the trade's first people pressure. It is worth taking apart, because the fix depends on what exactly is scarce.
Two kinds of knowledge in one head
The first is platform knowledge. It covers the engineering software and its licence keys, firmware versions, how ladder rungs and structured text behave, how redundant CPUs fail over and where the diagnostics hide. The second is industry knowledge. A cement kiln's burner management, a dairy pasteuriser's divert valve and a clarifier's rake drive each come with their own sequences, permissives and trips, and their own way of talking to operators. An engineer with one of the two can be useful within months. An engineer with both, for the platform and plant type you are quoting, takes years to grow.
Why the market will not fill the gap quickly
- The pool is small. Each platform and industry pairing narrows it further.
- The good ones are busy. Engineers with a rare pairing are well looked after where they are and seldom browse job portals.
- CVs blur the detail. Worked on PLC brand A could mean wrote the batch logic or watched someone else download it.
- Process sense does not transfer neatly. Years in pharma packing say little about a sugar mill's boiling house.
- Legacy platforms are shrinking. Fewer young engineers learn older controllers, yet plants keep running them for years.
Map it before an enquiry tests it
Rows: every engineer, with role and home base.
Columns: each controller platform you sell or support, then each industry you serve.
Cell entries: P for programs alone, C for commissions alone, S for supports remotely.
Pairings sheet: for each platform and industry pair you quote, list the names holding P, C and S on both sides.
Red flag: any pairing with a single name, or with every holder booked onto one project.
Owner: engineering head. Updated after every site handover. Read monthly alongside the pipeline.The competency and talent notes for automation companies describe a similar grid as a way to make one-name skills visible before a resignation does it for you.
Grow a deliberate second
- 1
Choose the pairing
Pick the platform and industry pair that most quotations need and fewest people hold.
- 2
Pick the learner
Someone who already has one half, such as the platform from another industry, or the industry on another platform.
- 3
Put them on the next live job
Give the learner defined modules, such as alarm handling or one pump sequence, not general shadowing.
- 4
Walk through the code weekly
The expert explains their own logic and the reasons behind it, with the learner asking why at each permissive.
- 5
Let the learner lead a site day
With the expert on the phone, not on the floor. That is the day the knowledge actually moves.
Keep the people who carry it
An engineer with a rare pairing knows their value, and so do your rivals. Pay should reflect the pairing, not just years or title. Offer first pick of the jobs that interest them, and credit them openly when a learner they trained leads a commissioning. Watch their site nights. The engineer everyone needs gets sent everywhere, and long stretches away push such people towards desk jobs. The retention notes for automation companies cover how to learn why engineers move. Written site travel and rest rules help spread the load.
Plan headcount against the platforms you quote
Every quotation for a new platform or a new industry is also a headcount decision. Before quoting, ask who would hold the pairing and who would be second. If no name comes to mind, the quote needs a hire, a pairing plan or a partner. Our pipeline-based headcount planning for automation firms plans staff against orders and the gaps between handovers.
Where to start
Sketch the grid this month, with platforms and industries across the top. Mark the pairings you quote most. Circle every pairing with one name. Pick the most exposed one and name a learner for the next job that uses it. The sector overview covers related patterns, including project knowledge that leaves with one engineer.
