Improve a software development process by treating it as a repeatable learning loop: measure delivery and failure for one service, find its biggest constraint, make one focused change, and check what happened. Smaller changes, frequent integration, dependable automation, and security built into development can help teams deliver faster without losing sight of quality.

Start with a baseline, not a target

Choose one application or service and record its results before changing the process. DORA’s current software-delivery performance model uses five metrics. Together, they show both how change moves and what happens when it causes problems.

Metric What it helps you understand
Change lead time How long a change takes to move from commit to production.
Deployment frequency How often the service is deployed.
Failed deployment recovery time How long it takes to recover when a deployment fails.
Change fail rate How often a deployment results in a failure that requires intervention.
Deployment rework rate How much deployment activity is unplanned corrective work rather than planned delivery.

Use the metrics for the same service and interpret them in context; they are not a ranking system for individuals or teams. DORA distinguishes throughput from instability, so a higher deployment rate alone is not proof of improvement. Look at whether delivery is moving more smoothly while failures and rework remain manageable.

Find the constraint that is slowing work

Map the path from code commit to production. Mark where work waits or changes hands, including review, testing, release approval, and deployment. The goal is to identify the material constraint—not to optimize every stage at once.

  • Note queues and delays as well as the work itself.
  • Check whether reviews, tests, or deployment steps are creating repeated waits.
  • Choose one constraint to address first, then compare the same service’s outcomes with its baseline.

Make changes smaller and shorten branch lifetimes

DORA recommends small, self-contained changes: they can move through the process faster and are easier to recover when something goes wrong. Reduce batch size before adding more tools. Keep branches short-lived so they do not drift far from the mainline and become harder to integrate.

Small changes also make failures easier to isolate. If a release causes trouble, a focused change gives the team a narrower set of likely causes to investigate than a large bundle of unrelated work.

Integrate continuously

Continuous integration relies on frequent merges to trunk or the mainline, automated build and test checks, and quick feedback. A merge should trigger the checks that matter for the service, so defects and integration problems surface while the change is still fresh.

  • Keep branches short-lived and merge frequently.
  • Automate build and test checks that can give useful feedback quickly.
  • Make ownership of failed checks clear so failures are addressed rather than ignored.

Frequent integration helps prevent branch divergence, but it works best when the team can trust its checks and resolve failures promptly.

Automate delivery without removing release safeguards

Once integration is dependable, build continuous-delivery capability with reliable automated tests, deployment automation, and safe release controls. Automation can make delivery more repeatable; it does not remove the need for sound architecture, capable teams, or a process suited to the service.

Evaluate a proposed change against its likely effect on throughput, instability, feedback speed, recovery effort, architectural fit, team capability, and implementation cost. A tool is useful when it removes a real constraint or provides a needed safeguard—not simply because automation is available.

Build security into the development process

NIST’s Secure Software Development Framework (SSDF) Version 1.1, published in 2022, organizes secure-development practices into four groups. NIST describes adoption as outcome-based: select practices according to the organization’s mission, risk tolerance, cost, feasibility, and potential for automation.

SSDF practice group Role in the process
Prepare the Organization Establish the organizational preparation needed to carry out secure software development.
Protect the Software Protect software and its development environment, including relevant access and provenance controls.
Produce Well-Secured Software Use development practices intended to produce software with fewer vulnerabilities.
Respond to Vulnerabilities Address vulnerabilities and use what is learned to prevent recurrence.

Operationally, NIST DevSecOps guidance supports collaborative review early in development, security checks in CI/CD, automated monitoring, and evidence collection. Place checks where they can give timely feedback, and collect production and security signals that help the team decide what to improve. Security is part of the delivery process, not a final gate that must discover every issue at the end.

Review outcomes and repeat the loop

After the focused change has had time to affect delivery, review the service’s metrics and relevant production signals. Discuss whether the constraint improved, whether failures or rework changed, and whether the change created a new bottleneck. Use that evidence to choose the next improvement rather than rolling out several unrelated process changes at once.

This approach keeps improvement grounded in the team’s actual work: measure, diagnose, change, and learn. DORA frames the goal as delivering better software faster; NIST’s SSDF similarly aims to reduce vulnerabilities, limit the potential impact of vulnerabilities that are not caught or addressed, and prevent their root causes from recurring.
