Prompt Engineering in Derby
Getting reliable, consistent output from language models for Derby businesses. Prompt engineering has a reputation for being a bag of tricks; in practice the work that matters is unglamorous — specifying the output precisely, building a test set, and measuring changes instead of trusting the impression of the last three attempts.
Why this comes up
The problem
The prompt has grown to two pages of increasingly emphatic instructions. It mostly works, nobody knows which parts are load-bearing, and every fix breaks something else.
What you get
What we deliver
- A test set of real inputs with agreed correct outputs, so changes are measurable
- Output format specified structurally rather than requested in prose
- Instructions rewritten to be specific about edge cases instead of emphatic in general
- Examples where the task is easier to demonstrate than to describe
- Model comparison on your actual task, since the best choice is task-dependent
- Prompts versioned in your codebase, not pasted between documents

Working in Derby
East Midlands
Derby is an engineering city — aerospace, rail and automotive supply chains — so the work here skews toward integration with existing plant systems, quality and compliance workflows, and reporting that has to stand up to audit.
Most work here involves connecting shop-floor and plant systems to reporting the rest of the business can actually read, plus quality and compliance workflows that have to survive an audit.

Prompt Engineering in Derby — common questions
- Why does adding CRITICAL and MUST stop helping?
- Because current models already follow instructions closely, and emphasis added to overcome older models' reluctance now causes overtriggering — the model applies the rule where it should not. Specificity outperforms emphasis, and it is worth deleting the shouting when migrating models.
- How do we make output consistent?
- Use structured output rather than asking for a format in prose. Most inconsistency comes from an ambiguous specification rather than from model randomness, and constraining the shape removes the problem instead of arguing with it.
- How do we know a prompt change actually improved things?
- By running it against a test set. Without one you are comparing a new prompt against your memory of the old one on different inputs, which reliably produces confident conclusions in both directions.
- Do prompts transfer between models?
- Partially, and the differences are worth re-testing rather than assuming. A prompt tuned to compensate for one model's habits can actively hurt on another, which is why a model upgrade deserves a prompt review rather than just a string change.
- Do you work with businesses across Derbyshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East Midlands, including Derby and the surrounding Derbyshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derby businesses do you usually work with?
- Most work here involves connecting shop-floor and plant systems to reporting the rest of the business can actually read, plus quality and compliance workflows that have to survive an audit. Beyond that we work across Advanced Manufacturing, Aerospace, Rail Engineering, Automotive and Logistics.
- Do you cover the areas around Derby?
- Yes — we work throughout East Midlands, including Nottingham, Leicester, Loughborough, Birmingham. Derby is an urban area of roughly 260,000+, and we take on work across the wider Derbyshire region rather than the city boundary alone.
