The Dora Quartet: Metrics That Make Devops Tick

4 min read

Beginning the path of DevOps, a disruptive approach to developing software and IT operations, necessitates a thorough grasp of the key performance metrics that characterise success. It acts as a helpful reference to the core metrics developed by the DevOps Research and Assessment (DORA) group. 

In this quintet of measurements, deployment rate, lead time for modifications, failure of changes rate, and the length of time for resuming service are identified as critical factors in determining the efficiency, dependability, and overall effect of DevOps techniques. This investigation not only reveals the technological complexities of DevOps, but also emphasises its social and institutional importance. 

What Are Dora Metrics?

The DORA 4 metrics, sometimes known as the DORA quartet, are an assortment of indicators of performance (KPIs) used to evaluate the efficacy and success of DevOps methods inside a business. These measures were created by the research group at DORA, that is now a component of Google Cloud. The DORA metrics examine several elements of the software distribution process, giving useful information on the performance, effectiveness, and dependability of DevOps deployments. The four key DORA metrics are listed below:


1. Deployment frequency

  • Definition: The regularity at which a company deploys fresh software or puts changes into production.
  • Purpose: Measures how fast and efficiently a company can provide new features, upgrades, or problem fixes to end consumers.

2. Lead time for changes

  • Definition: The amount of time it takes to go from coding commit to successfully operating in production.
  • Purpose: Demonstrates the effectiveness of the creation and deployment processes, emphasising the speed with which changes are applied.

3. Change Failure Rate

  • Definition: The proportion of modifications (deployments) that fail and require remediation.
  • Purpose: Demonstrates the deployment process's dependability and stability, with lower failure rates suggesting a more robust system.

4. Time to restore service

  • Definition: The time required to restore service following a service event or outage.
  • Purpose: Assess a company's capacity to recover swiftly from interruptions in service, highlighting the system's durability.

What is the difference between SLI vs SLO?

SLI vs SLO are words used in the setting of service quality management, representing distinct elements of evaluating and defining reliability of service.

1. SLI (service level indicator)

  • Definition: SLI is a statistic or measurement that represents a service's performance or dependability. It measures a certain component of service behaviour across a given time period.
  • Purpose: The objective of SLIs is to accurately assess and assess a service's performance. They are frequently part of a larger collection of metrics that describe the general condition and functioning of the service in question.

2. SLO (Service Level Objectives)

  • Definition: A SLO is a target or objective established for a certain SLI. It shows the service provider's desired degree of performance or dependability.
  • Purpose: The purpose of SLOs is to define expectations among the assistance provider and the client. They describe the expected level of quality of service and assist in setting measurable and attainable objectives.


The quartet, which includes deployment rate, lead time for modifications, failure of changes rate, and the length of time for resuming service, appears as an extensive structure for enterprises to analyse DevOps maturity and improve their software distribution pipeline. These indicators not only assess the technical elements of deployment and dependability, but also highlight the social and organisational changes that accompany the DevOps journey.
