Case Study

Overview
HMI design & application development for a high quality feature-rich Infotainment system of an Automotive Tier 1
About the Client
The client is one of the world's largest automotive parts manufacturers specializing in infotainment and connectivity, complete vehicle electrical systems, HVAC and automotive safety, powertrain & chassis components.
 
Business & Technology Context
The client was looking for a partner who could independently develop a high quality HMI with tight delivery schedule. The unique and feature-rich infotainment module would be future-proof of any technology innovations. KPIT successfully fulfilled these requirements with the engagement starting in April 2015 planned for deliverables within a span of two years.
Key Highlights


Agile development methodology deployed with a scheduled 7 week release cycle.

Multi-location, multi-national team built or the project with a team readiness of 100+ experts, a dedicated architect & project lead per domain to run things in parallel.

Quick ramp up - Scaled up 40 resources within 1-2 months, catalysed by in-house HMI training program for Qt/QML/C++.

Proposed joint IP for development of reusable HMI Framework.

Extreme quality assurance with focus on tools and automation - Use of KPIT’s proprietary continuous build automation (CBA) system for integration of multiple tools and their daily execution.

Scope of work for KPIT - High alignment with customer processes, practices, tools

KPIT's Solution
KPIT created a joint IP in HMI development framework- ‘Kwik framework’ for the client. Apart from the high level design & detailed HMI framework, the scope of the work included HMI (QML) & HMI Model development using (Qt/C++), business Logic development & middleware integration. ‘Kwik’ HMI was deployed to improve the overall reusability, productivity, maintainability and quality.
  • Centralized configuration and build mechanism.
  • HMI design & application development around applications such as Bluetooth, Wi-Fi, Audio/Radio, Media, Connection Manager, Projection, Messaging, Phone, Vehicle Function & Voice Recognition.
  • Verification & validation strategies – for unit testing, functional testing and integration testing targeted at 100% requirement coverage.
 
These activities included requirement analysis for identifying gaps, coding with MISRA C++ guidelines, HMI testing on host PC Automated execution (squish), unit test case development, functional test cases development & automated test execution with coverage.
As a part of the engagement, KPIT delivered:
500+ Features
20+ Modules
3 Different display sizes
60+ Team Size
Success Benefits
Worked with Tier 1 client for establishing of long term HMI strategy which includes usage of tools, agile development, reusability, building and testing cost optimization across programs and regions.
Demonstrated entire architecture with key use cases to Tier 1 & OEM customer within first 3 - 4 months of project initiation.
Extreme quality control with focus on tools, HMI testing, Cost optimization and automation: 100% reviewed artifacts, 100% coverage of critical use cases.
Extensive use of tools and alignment with customer specific tool ecosystem.
Reusability & Future proofing: The reusable test automation frame work can be used for development of different MYs/ future variants by the Tier 1. KPIT’s robust delivery processes and governance mechanism helped in achieving all the deliverables with improved turnaround time.
