Unit 4004 Managing a Professional Engineering Project – AI Project Sample with Pass, Merit and Distinction Coverage (2026–27)

For information and reference only – not to be submitted as your own work.

This is a model extract written to show how a Unit 4004 project can be structured against the Pearson criteria. The project, company data and all figures are illustrative. Your centre sets your own project brief, and your tutor and Pearson’s assessment rules decide what counts as your own evidence. Use this page to understand depth, structure and referencing, then build your project from your own workplace or college problem.

What this Unit 4004 AI project sample shows

Unit 4004 Managing a Professional Engineering Project is a Level 4, 15-credit unit assessed through a Pearson-set theme (Pearson, 2024). The Pearson-set theme for 2026–27 delivery, as given in the brief this sample follows, is Artificial Intelligence in engineering and manufacturing (confirm the dates and wording with your centre). Your centre writes the project brief around that theme, so every learner’s project is different.

The Pearson authorised brief for this unit places you as an engineering technician at a fictional company, Innovate Engineering Ltd. You plan a project, run it, write a technical report of up to 5,000 words and present your outcomes. This extract follows that same four-phase route using one AI project idea, and shows where each criterion is evidenced.

Brief details and the task wording are on the live Unit 4004 Managing a Professional Engineering Project assignment brief 2026 page. For a step-by-step explanation of how to plan your own project, read our guide to planning a Unit 4004 AI engineering project.

Criteria map for this extract

Phase 1: Project proposal and project management plan (LO1)

1.1 Project selection and justification (P1)

Working title: AI-assisted predictive maintenance for CNC machining cell 3 at Innovate Engineering Ltd.

The problem. Cell 3 holds two vertical machining centres that produce aluminium brackets for an automotive customer. Over the last two quarters, the maintenance log recorded 11 unplanned spindle and coolant-pump stoppages (illustrative figure). Each stoppage lost around four hours of production and, on two occasions, a late delivery penalty. Maintenance is currently time-based: parts are checked on a fixed calendar whether they need it or not.

Why this project. Predictive maintenance fits the 2026–27 AI theme well, because it links data, analytics and asset management to a measurable downtime problem. Machine learning methods are now widely used to predict equipment faults from sensor data (Carvalho et al., 2019), and the cyber-physical approach of linking machine data to decision-making is well established in Industry 4.0 manufacturing (Lee, Bagheri and Kao, 2015).

The project is also realistic for an HNC learner: it uses data the company already collects, plus low-cost vibration sensors, and does not need a full software team. Machine-learning terms in this report follow Russell and Norvig (2021).

Aim. To design, trial and evaluate a machine-learning anomaly-detection tool that warns maintenance staff of developing spindle and pump faults on cell 3, with a human engineer approving every maintenance action.

SMART objectives.

1. Review at least eight secondary sources on AI-based predictive maintenance and summarise suitable methods by week 3.
2. Collect four weeks of vibration, spindle-load and temperature data from both machines by week 7.
3. Train and test an anomaly-detection model, targeting a fault-detection rate of at least 75% on logged historical events, by week 10.
4. Run a two-week supervised trial with maintenance staff and record every alert, decision and outcome by week 12.
5. Present findings, a cost-benefit case and recommendations to the engineering manager in week 14.

1.2 Feasibility study (M1)

Three solution options were compared before the project was confirmed. A feasibility study is not a formality here; it is what turns “I want to do something with AI” into a project an assessor can see is viable.

SWOT analysis of the preferred option (ML anomaly detection on an edge device)

Pugh matrix (datum = current time-based maintenance)

Option A is cheaper and easier to explain, but fixed thresholds give little extra warning compared with current practice, so it is kept as a fall-back. Option B is selected because it adapts to each machine’s normal behaviour and meets the AI theme. Option C fails on budget and timescale.

Technical, economic and operational feasibility (illustrative). Hardware (two tri-axial vibration sensors, a single-board computer and cabling) is estimated at £1,150. Learner and supervisor time is covered by the HNC sponsorship agreement. If the tool prevented even three stoppages a year, at an estimated £600 lost contribution per stoppage (£1,800 a year, illustrative), payback on the £1,150 hardware would be under one year. Operationally, the trial runs in shadow mode first so production is never stopped by the AI alone.

1.3 Project plan and Gantt chart (P2)

The plan follows a simple work breakdown structure: initiation, research, data collection, model build, trial, evaluation and reporting. The schedule is shown below as a Gantt-style table; in the real submission this would be produced in Microsoft Project or GanttProject, with dependencies and the critical path shown.

Critical path (illustrative): 1 → 3 → 4 → 5 → 6 → 7 → 8. Task 2 has two weeks of float, and task 9 runs alongside tasks 7 and 8. Resources: the learner (about six hours a week), a maintenance technician for installation, the IT team for network approval and a supervising engineer for sign-offs.

1.4 Risk register

Risks were assessed using a 1–5 likelihood and 1–5 impact scale, following the general process in ISO 31000:2018 (identify, analyse, evaluate, treat, monitor).

1.5 Legislation and ethics and their effect on the plan (D1)

Distinction at D1 is about effect, not a list of laws. The question to answer is: what did each requirement change in the plan?

The combined effect was to add about one week of approval work and to change the success measure from “the AI predicts faults” to “the AI helps engineers predict faults safely”. That shift is the kind of judgement Distinction criteria reward.

Phase 2: Project implementation (LO2)

2.1 Logbook extract and progress against plan (P3)

2.2 Methods for monitoring milestones (M2)

The Gantt baseline plus milestone trend analysis was chosen because the main risk was schedule slippage, not cost. This matches Lock’s (2013) advice that the control method should fit the scale of the project rather than the other way round.

2.3 Critical evaluation of the plan (D2)

The plan was broadly successful: four of six milestones were met on time, and the one-week slips at M2 and M4 were absorbed by float. But it had two weaknesses. First, IT approval was treated as a two-week task when the company’s process actually takes three to four; that should have been on the critical path from day one. Second, the plan assumed fault data would arrive naturally, which was optimistic for two machines over four weeks.

Recommendations: start approvals before the proposal is signed off; plan a longer baseline period or pool data across similar machines; add a formal “go/no-go” review after model testing so the trial is not rushed.

Phase 3: Technical project report (LO3)

3.1 Outcomes of each stage (P4)

The report would take the reader through each stage in order: the problem and objectives, research findings, method, data, model results, trial results and cost-benefit outcome. It is written for a reader with little prior knowledge of machine learning, so terms such as “anomaly” and “false alarm” are defined on first use.

3.2 Critical analysis and evaluation techniques (M3)

Confusion matrix for the trial (illustrative)

Detection was good (3 of 4 developing faults), but precision was low: only about one alert in five was a real fault. A fishbone (Ishikawa) analysis of the false alarms pointed to two causes: tool changes creating short vibration spikes, and coolant temperature drift on night shifts.

A simple cost-benefit comparison then tested whether the tool was still worth using with that false-alarm rate. Each false alarm cost about 15 minutes of an engineer’s time, which is small compared with a four-hour stoppage.

3.3 Critical analysis of outcomes and further development (D3)

The honest conclusion is that the tool is useful as an early-warning aid, not yet as a decision-maker. That is consistent with good practice on human oversight of AI systems (DSIT, 2023). Further development should: filter out tool-change events using the machine’s own program signals; add the coolant pump current as an input; extend the trial to three months; and test whether a simpler threshold method (Option A) performs almost as well, because a simpler tool that staff trust may deliver more value than a smarter one they ignore.

Phase 4: Presentation, reflection and CPD (LO4)

4.1 Presentation outline (P5)

4.2 Analysis of own behaviour and performance (M4)

Using Gibbs’ (1988) reflective cycle, the main lesson was about over-confidence in the early weeks. The learner assumed the data would “speak for itself” and spent too little time talking to the maintenance technicians who understood the machines. When the first model produced a 30% false-alarm rate, a ten-minute conversation with a technician revealed the spindle-speed effect. Next time, user interviews would sit in week 2 of the plan, not happen by accident in week 8.

4.3 CPD plan
