NTPEP DataMine

About this project

NTPEP DataMine (National Transportation Product Evaluation Program) is the online repository of data and audit reports for all NTPEP services. It’s a user role based system;

  • Manufacturer user submits different Products/Audit,
  • AASHTO user receives these requests and assign to
  • Lead State user who again reassign all approved requests to Testing Facility,
  • Testing Facility then tests/audit the products and publishes results back to Manufacturer or Public.

Requirements and Assumptions

This system was initially built back in 2000 but with the growing developments in technology, new business requirements and inadequate user experience, an enhanced system formation was inevitable.

Following are some of the requirements by the client and assumptions and goals I have observed after conducting detailed usability analysis of the old system.

  • Better user experience, improved information flow and appropriate information architecture
  • Inclusion of industry proven design patterns
  • Modern role based dashboard system
  • Well analysed application submission process
  • Appropriate status during application life cycle
  • High availability of data by
    • Well-structured/analyzed tabular grids
    • Contextual filters
    • Multi-level searches
    • Products/Audit reports graphical timelines
    • Event Calendars
    • Libraries
  • Modern, corporate and sleek UI
