Code review is a critical part of your build process. And when you do code review right, you can streamline your build process and achieve DevOps. Most code review tools work great when you have a team of 10 developers. But what happens when you need to scale code review to 1,000s of developers? Many will struggle. But you don’t need to. Join our experts Johan Karlsson and Robert Cowham for a 30-minute webinar. You’ll learn: -The problems with scaling code review from 10s to 100s to 1,000s of developers along with other dimensions of scale (files, reviews, size). -The solutions for dealing with all dimensions of scale. -How to utilize Helix Swarm at massive scale. Ready to scale code review and streamline your build process? Get started with Helix Swarm, a code review tool for Helix Core.

• Pre-commit build (& test) / pre-commit review
• Highest quality, but slows developers down
• Pre-commit build / post-commit review
• Pragmatic balance between speed and quality
• Build doesn't get broken – not waiting for humans!
• Post-commit build / post-commit review
• Risks breaking build which impacts other team members

• Mistakes can be VERY expensive.
• Including a lot of variant management
and traceability across variants.
• Tape-out dates, etc.: very low
acceptance of any bugs in the product.

Use Code Review to Comply
• Very big mixture of projects. Some
small, some very large.
• Component-based development,
always starts from certain base layers.
• Regulations and industry standards
defines most of the process (AUTOSAR,
Automotive SPICE).
• Products and components stay around
for many, many years.
