The DORA model provides an industry standard for measuring software delivery performance, focusing on four key metrics: Lead Time for Changes, Deployment Frequency, Change Fail Rate, and Time to Restore Service. Improving lead time for changes is crucial as it measures an organization's ability to deliver value to customers, run experiments, and receive feedback in a timely manner. To improve this metric, it's essential to measure cycle time, which breaks down the process into smaller intervals to identify areas for improvement. By analyzing each step of the software development process, including coding, waiting for review, reviewing code, and merging and deploying, organizations can pinpoint bottlenecks and implement changes that increase productivity and efficiency. Tools like FlexReview can aid in completing code reviews faster and more efficiently, reducing organizational stress and improving overall lead time for changes.
