Can diagnostics software move to the web? An independent review for Jaguar Land Rover
JLR’s technicians use Symptom Driven Diagnostics (SDD) software to diagnose vehicle faults, and JLR wanted to deliver it through the web instead of installing it on individual machines. Before committing to what could be a major build, it asked Box UK whether the existing software could be adapted, and at what cost.

In short
- Jaguar Land Rover technicians use SDD software to diagnose vehicle problems.
- JLR wanted to make it available through the web rather than installed on each machine.
- It needed to know whether the current software could be repurposed, and the cost and timescale involved.
- Box UK reviewed the code line by line and ran usability workshops.
- A prototype showed how the software could be developed in line with best practice.
- JLR received a validated roadmap for scaling SDD internationally.
Customer background
Jaguar Land Rover builds premium vehicles sold worldwide. Its dealer and service technicians use JLR’s diagnostic software (SDD for older models, Pathfinder for newer ones) to find and fix faults consistently, wherever the vehicle is serviced.
The challenge
JLR wanted to make SDD more accessible by delivering it through the web rather than requiring installation on individual machines. That could be a significant development project, so before starting, JLR needed to know whether the current software could be repurposed, and what it would cost and how long it would take.
Our approach
Workshops with JLR stakeholders showed the software was stable but had grown over time to meet different teams’ needs, leaving a complex underlying architecture.
Our technical consultants reviewed the code line by line to assess its structure and suitability for web delivery. At the same time, our UX consultants ran workshops to evaluate the software’s usability, and built a prototype showing how it could be developed further.
What we delivered
- A technical assessment of the code and architecture.
- A usability evaluation and a prototype of an improved interface.
- A roadmap showing how SDD could be scaled across territories while keeping a consistent, high-quality experience for technicians.
The outcome
JLR gained an independent, evidence-based view of whether to rearchitect SDD for web delivery, and a validated roadmap if it chose to. Box UK went on to provide agile coaching to JLR teams.
Frequently Asked Questions
Review the code and architecture against the new requirement before committing. For JLR, a line-by-line code review showed what adapting SDD for web delivery would involve.
Assessing whether the architecture can be separated into a web-deliverable front end and services, what needs rewriting, and how usability will change.
Because a technically sound plan that ignores how people use the software can still fail. JLR’s review covered both.
What this means
for your organisation
If you’re thinking about moving installed software to the web, or scaling it to new markets, the first question is whether what you have can get you there. Answering it properly before committing budget can save a lot of money, whichever way the answer goes.
If that’s a decision in front of you, send us a few lines about the software. We’ll tell you what a review would need to cover.
