Grade X, Vehicle Diagnostic Software
Grade X, a Bosch vehicle diagnostic tool is a browser-based software used by a technician to check the status of a vehicle and detect possible problems.
Improving technicians experience by creating easy to navigate interface, pleasant and intuitive design and easy to organise a large number of additional complex tools. The software should reflect Bosch’s high standards of creating tools to help technicians with their day to day work.
User report the main findings
Research conducted by internal Bosch team. The in-depth report not available. All interviewed participants were males 20 to 60-year-old.
- The software is hard to use – a major complaint
- The very steep learning curve for new users
- Unintuitive interface – inconsistency in labelling and naming convention
- Broken links
- Younger users were far more skilled in the new digital environment.
- In general, junior staff were significantly more knowledgable about computing than senior colleagues.
- Senior users were more efﬁcient using existing software
Evaluation of existing software
I evaluated the software and found a number of problems. The main issues were inconsistency, hectic and confusing layout and broken links.
After the review, the major parts of the software were laid out in the diagram.
We conducted a number of activities, including improving interaction and user flows.
After the outline of the interaction was agreed, a map of the application was created and the most important journey was determined (seen as red rectangles in the next image)
The next stage of product development was created using pen and paper. More than 80 quick low fidelity wireframes were created
Wireframes and prototypes were created in order to understand functionality and layout.
Visual mobile interface design (the mobile version is limited to access some complex service tools)
Visual interface design – desktop version, full mode.
