5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Daily Work Prioritisation Follows supervisor's instructions; escalates conflicts. Prioritises routine tasks based on established guidelines; escalates urgent conflicts. Independently prioritises daily planned work and allocates resources; consults manager on significant schedule deviations due to 'break-in' work.
Technical Troubleshooting & Repair Method Performs repairs as instructed; seeks guidance for complex diagnostics. Independently diagnoses and repairs common faults; proposes solutions for unusual issues. Makes definitive technical decisions on complex faults; designs and approves repair procedures; leads Root Cause Analysis.
Parts & Materials Procurement Identifies parts needed from BOM; requests through supervisor. Orders standard parts within established limits; flags potential shortages. Approves parts requisitions up to £500; recommends critical spares and works with Procurement on alternative suppliers; flags budget impacts.
Safety Protocol Enforcement Adheres strictly to LOTO and safety procedures. Ensures team adherence to safety protocols; reports near misses. Enforces all safety protocols rigorously (e.g., LOTO, confined space); stops unsafe work immediately; leads incident investigations.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

PM Compliance
Percentage of scheduled Preventive Maintenance tasks completed on time.
Target · >95%

If we schedule 100 PMs this month, you need to make sure at least 95 of them are finished within their due date window. We're talking about actually doing the work, not just ticking a box.

Schedule Compliance
Percentage of planned (non-urgent) work orders completed as scheduled.
Target · >90%

You planned 50 jobs for the week that weren't breakdowns. If 45 get done, that's 90%. This shows how well you plan and how few 'break-in' jobs derail you.

Mean Time To Repair (MTTR) for Top 10 Assets
Average time taken to repair our most critical pieces of equipment once they've failed.
Target · Reduce by 10% year-on-year

If our critical XYZ machine typically takes 4 hours to fix, we want to see that drop to 3.6 hours. This means better troubleshooting, faster parts retrieval, and quicker decision-making.

Safety Incident Rate (Team)
Number of recordable safety incidents within your team.
Target · Zero Lost Time Incidents (LTIs)

This is non-negotiable. We want zero accidents that cause someone to miss work. Your job is to make sure everyone works safely, every single time.

Work Order Quality
Completeness and accuracy of work order documentation (e.g., fault codes, repair actions, parts used).
  • Work orders consistently include clear descriptions of the problem, detailed repair steps, accurate parts consumption, and technician notes. Fewer follow-up questions from the planner or manager. Data is actually useful for Root Cause Analysis.
Team Development & Mentorship
Effectiveness in guiding and upskilling junior technicians.
  • Junior team members are asking more insightful questions, taking on more complex tasks, and showing improved troubleshooting skills. You're regularly providing constructive feedback and coaching. They're not just 'part-swappers' anymore.
Cross-functional Collaboration
How well you work with other departments, especially Production and Stores.
  • Production supervisors proactively involve you in their planning. Stores staff tell us you're easy to work with and give them good lead times. Fewer 'us vs. them' situations. Things just run smoother because you're talking to people.
Problem Solving & RCA Application
Your ability to get to the bottom of recurring issues, not just patch them up.
  • You're leading 5 Whys sessions, bringing data to the table, and actually implementing solutions that stop repeat failures. We see fewer 'bad actors' on your shift. You're moving beyond quick fixes.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Problems

You'll be the one digging into why a machine keeps failing, using tools like 5 Whys or Fishbone diagrams. When a tricky fault crops up, you're excited by the challenge of figuring it out, not daunted.

A specific pump keeps failing every three months despite routine PMs. You'll lead the investigation, analyse the data, and propose a permanent fix that actually works, rather than just replacing the pump again.

Developing and Leading a Team

You enjoy coaching junior technicians, helping them understand the 'why' behind the 'what.' You get satisfaction from seeing your team improve their skills and take on more responsibility, turning them into proper problem-solvers.

You'll spend time in the field with a new technician, showing them how to properly troubleshoot a motor fault, explaining the electrical diagrams, and letting them lead the repair while you guide them.

Driving Efficiency and Reliability

You're always looking for ways to make our maintenance processes better, whether it's optimising PM schedules or improving our spare parts management. You get a real buzz from seeing less downtime and smoother operations.

You'll review our PM programme for a critical asset, identifying tasks that aren't adding value and proposing new predictive maintenance techniques that save us money and prevent future failures.

What frustrates people
  • The 'Squeeze Play': Being pressured by Production to release equipment early from a PM window, then being blamed when that same asset fails a week later due to the incomplete work.
  • Procurement Battles: Fighting with the purchasing department over their decision to buy a cheaper, non-OEM part that you know will fail prematurely, just so they can hit a cost-saving metric.
  • Data Garbage-In, Garbage-Out: Knowing your CMMS is full of poorly written, incomplete work orders from the off-shifts, making it impossible to run accurate failure analysis.
  • Deferred Maintenance Debt: Being forced to constantly postpone non-critical PMs to meet short-term budget goals, all while knowing you're creating a multi-million pound reliability time bomb.
What this role does not give you
  • A quiet, predictable 9-to-5 desk job. Expect urgent calls and unexpected challenges.
  • Complete control over all resources and budgets; you'll still need to justify your requests.
  • A role where you're solely hands-on; you'll be leading and planning more than doing the actual wrenching.

8Who you work with

This role directly influences the operational uptime and efficiency of our production lines. By ensuring planned maintenance is executed effectively and reactive work is minimised, you'll help reduce operational costs, improve product quality, and significantly contribute to meeting our overall production targets. Get it right, and we save money and keep customers happy. Get it wrong, and we're losing thousands of pounds an hour.

Inside the business
  • Production Supervisors
  • Health & Safety Officer
  • Procurement Team
  • Warehouse/Stores Manager
  • Engineering Team
Outside the business
  • Key Equipment Vendors
  • Specialist Contractors
  • Safety Auditors

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 5 years of hands-on maintenance technician experience in a manufacturing or heavy industrial environment, where you've seen a bit of everything.
  • Demonstrable experience leading small teams or mentoring junior colleagues, even if it wasn't a formal 'supervisor' title.
  • Proven track record of improving equipment reliability or reducing downtime through structured problem-solving (e.g., leading RCAs).
  • Strong understanding of CMMS systems; you should be comfortable building and running reports, not just closing work orders.
  • A solid grasp of health and safety legislation, particularly LOTO procedures; you'll be enforcing this, so you need to know it inside out.

10What to practise next

Where the job is going, and what to do about it starting this week.

IIoT & Sensor Data Interpretation

More of our equipment is getting 'smart' sensors, generating a constant stream of data. You won't be a data scientist, but you'll need to understand what that data is telling you, how to spot an anomaly, and how to translate it into a maintenance action. This is moving us from reactive to truly predictive.

Basic sensor types · Trend analysis · Alarm management · Data quality issues

  • This week: Spend an hour with our PdM specialist; ask them to explain how they interpret the data for one critical asset.
  • This month: Get access to the raw sensor data dashboards for your area; try to spot trends yourself.
  • Month 2: Take an online introductory course on Industrial Internet of Things (IIoT) or condition monitoring.
  • Month 3: Propose one new PdM-driven work order based on your own data analysis, justifying it to your manager.

Quick win: Start regularly reviewing the PdM dashboards for your top 3 'bad actors' and try to correlate sensor spikes with past failures. You'll start to see patterns.

Basic AI/ML Output Validation

As we use more AI for things like predictive work orders or root cause analysis, you'll need to be able to 'sanity check' its recommendations. AI is great, but it's not perfect, and a wrong recommendation could be costly or dangerous. You'll be the human in the loop.

Understanding confidence scores · Identifying 'hallucinations' · Bias awareness · Feedback loops

  • This week: When an AI-generated work order comes through, manually verify all the details before approving it.
  • This month: Challenge one AI recommendation that doesn't 'feel' right; investigate why and provide feedback to the system owner.
  • Month 2: Read an article or watch a video on the limitations of AI/ML in industrial applications.
  • Month 3: Work with the IT/Data team to understand how our internal AI models are trained and what data they use.

Quick win: Don't blindly trust the AI. Always ask 'does this make sense?' and 'what could be wrong here?' before acting on its suggestions. Your experience is still crucial.

11Staying current once you are in

What people here do to keep up
  • Regularly attend industry webinars or conferences on maintenance and reliability trends.
  • Join professional organisations like the Institute of Asset Management (IAM) or SMRP.
  • Participate in internal cross-functional improvement projects, especially those focused on OEE or cost reduction.
  • Seek out opportunities to mentor junior technicians and share your knowledge.
  • Stay up-to-date with new safety regulations and best practices.

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Data Storytelling for Maintenance

We're drowning in data from our CMMS and PdM systems, but often struggle to turn it into compelling arguments for investment or process changes. Being able to explain 'why' we need to spend £50K on a new sensor system, not just 'what' it does, is becoming crucial.

  • Audience-centric communication
  • Visualisation best practices
  • Narrative structure

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, you're juggling a lot. Planning, scheduling, troubleshooting, mentoring—it's a lot of plates to spin. What if you could get back a significant chunk of your week, not by working less, but by working smarter? Our AI Productivity Hub is designed to do just that for Maintenance Supervisors.

Imagine having a digital assistant that handles the tedious, repetitive parts of your job, leaving you free to focus on the complex problem-solving, team development, and strategic thinking that only a human can do. We're talking about real-world applications that cut through the noise and give you back your time.

Predictive Work Order Generation

AI monitors our IIoT sensor data (like vibration or temperature) to spot tiny anomalies that usually mean a failure is coming. It then automatically drafts a detailed, pre-populated work order in the CMMS, suggesting exactly what needs doing. No more sifting through dashboards, just actionable tasks ready to go.

Root Cause Analysis Accelerator

When that 'bad actor' machine fails again, AI instantly pulls up all its past work orders, parts used, and technician notes. It highlights correlations and suggests the most likely root causes for you to investigate first, saving you hours of manual digging through historical data. Get to the real problem, faster.

Smart Spare Parts Advisor

As a technician logs a specific failure mode on their tablet, AI cross-references the asset's Bill of Materials (BOM) and historical usage. It then recommends the exact parts needed, checks if they're in stock, and even tells you their precise location in the storeroom. Less time chasing parts, more time fixing things.

Standardised Job Plan Drafter

Need a new PM procedure? You just tell the AI the asset type and the general tasks. It then drafts a comprehensive job plan, including all the safety steps (like LOTO), the tools you'll need, and estimated times, pulling from manufacturer manuals and our own best-practice library. Saves you hours of writing from scratch.
