The instinct when a line cannot keep up is to buy more capacity. Often that is the wrong move — or at least a premature one. A surprising share of “missing” capacity is already sitting inside the equipment you own, lost to stoppages, slow running and defects that never show up on a purchase order. Overall Equipment Effectiveness (OEE) is how you find it, and process optimisation is how you capture it — frequently before any new machine is justified.

To set scope: RoboHub Africa provides industrial automation advisory, optimisation and managed support — not consumer robotics, robotics education, AI products, or RPA software. Improving OEE here means getting more out of physical industrial automation, vendor-neutrally.

What OEE Actually Measures

OEE is the product of three honest fractions, and each one points at a different kind of lost capacity.

Availability

The share of planned time the line is actually running. Lost to breakdowns, changeovers and waiting — the gap between scheduled and running.

Performance

How close the line runs to its rated speed while it is running. Lost to micro-stops, slow cycles and minor stalls that rarely get logged but quietly bleed output.

Quality

The share of output that is good first time. Lost to scrap and rework — capacity you paid to produce and then threw away.

Multiply the three and you get a single number that is brutally honest about how much of your nominal capacity you are really getting. A line that feels busy can have a far lower OEE than the floor believes.

Where the Hidden Capacity Hides

Changeovers and set-up that take longer than they should
Micro-stops too small to log but large in aggregate
Running below rated speed “to be safe”
Scrap and rework that quietly consume good capacity
Unplanned downtime that better maintenance would prevent

Each of these is recoverable without buying a single new machine — which is precisely why OEE is the cheapest capacity you will ever find.

How Optimisation Captures It

Process optimisation turns the OEE picture into action: targeting the biggest losses first, tightening changeovers, stabilising speed, attacking the root causes of scrap, and improving maintenance so availability rises. It is advisory and capability-building, not a machine sale — and it routinely defers or shrinks the capital spend a plant assumed it needed.

Where Standards and Support Fit

Optimisation is delivered to recognised practice — IEC 61131-3, ISO 10218-2 / ISO 12100, IEC 61508 / IEC 61511 (SIL), IEC 61439, ISA-95 and IEC 62443 — described as the framework we work to, with certifications and OEM-partner badges claimed only where actually held. Sustained OEE depends on maintenance, which is why optimisation and managed automation support work together. All of it sits within Ghana’s Factories, Offices and Shops Act 1970 (Act 328) and DFI safety regime — not the GSA.

What It Costs

A process-optimisation engagement is scoped and quoted per engagement — it depends on the line and the scope of work, so there is no flat published rate. We quote against your actual requirement, never an invented figure.

Frequently Asked Questions

Will optimisation alone remove the need for new equipment?

Sometimes — and even when it does not, it sizes the real gap so any new capital is justified rather than guessed. The point is to exhaust the cheap capacity first.

Is this RPA or AI-driven “optimisation software”?

No — this is industrial process and OEE optimisation on physical automation. Not RPA bots or AI products.

Do you need to have installed our line to improve it?

No — we can assess and optimise existing automation, whoever installed it, vendor-neutrally.
