Shifting left has become increasingly important in the software development industry as organizations strive to release high-quality software products more quickly and efficiently. By integrating observability, security, and testing practices earlier in the development cycle, developers can identify and address issues more effectively.

Observability provides real-time insights into software application behaviour, enabling proactive problem-solving and the identification and resolution of performance or scalability issues. Incorporating observability practices early in the development process can enhance software quality and reduce development time and costs. Similarly, integrating security testing and analysis early on can identify and address potential vulnerabilities before they become more difficult and expensive to fix, reducing the risk of security incidents.

Overall, shifting left encourages greater collaboration and communication between developers, testers, observability engineers, and security experts, fostering a culture of continuous improvement and learning. By prioritizing early testing, observability, and security, teams can achieve greater efficiency, reduce the time and effort required for testing and debugging, and ultimately deliver more secure, reliable, and successful software products.
