Unlocking the true potential of CI/CD pipelines for improved productivity 

Measuring developer productivity has always been a challenge in the software industry. Traditional metrics like committed code or merged pull requests provide some insight but often fail to capture the true impact of developers’ work.  

Consider this scenario: a developer merges just one pull request in a week, consisting of only one line of code, yet this change could potentially save millions for the company. Why did it take so long for just one line of code? The answer lies in understanding the problem and the process that led to that line. 

Now, imagine scaling this scenario to a larger enterprise with hundreds of developers. The task of measuring productivity becomes even more daunting. While it’s important to track metrics, especially in the era of remote work, relying solely on traditional metrics may not offer a clear view of development productivity. 

The role of pipeline execution time 

In my experience, prioritising pipeline execution time offers a more precise gauge of development productivity. Allow me to exemplify this with a scenario. Let’s say you manage a pipeline that runs a hundred times daily, requiring 30 minutes to go through all its stages.  

Now, envision an enhancement is implemented, reducing the completion time down to 20 minutes. This seemingly minor adjustment yields a significant saving of 1000 minutes in development process time, approximately 16 hours.  

Should this enhancement extend to other Integration/Continuous Deployment (CI/CD) pipelines within the enterprise (let’s assume another 100 pipelines), the cumulative effect results in a staggering 1600 hours of saved development time, equivalent to nearly 2 months of saved time that can be used for some other tasks. And let’s not overlook the impact on computing costs. 

You might wonder how this relates to Internal Developer Portals (IDPs) and how they can help save time. IDPs are adopted to speed your development process but also to standardise the way software is created.  

One of the aspects it standardises is development CI/CD pipelines and when all pipelines follow the same standards, rolling out changes becomes a matter of minutes or hours instead of months or quarters.  

This not only makes the process more efficient but also encourages continuous improvement. Overall, optimising your development process through IDPs can lead to significant time savings and increased productivity.  

The importance of pipeline stability 

Pipeline optimisation does not always mean reducing time; stability is also of great importance. You might want to include new steps that could make your pipeline slower but more stable.  

For main workloads, the DevOps Research & Assessment (DORA) team has defined four metrics that every pipeline should measure and monitor: 

• Deployment frequency: This measures how often you release your workloads. 
• Lead time for changes: This measures how long it takes for a commit in your repository’s main branch to reach production environments. 
• Time to restore service: This represents the duration between the detection and resolution of an issue. 
• Change failure rate: The rate of changes that cause an incident needs to be fixed. 

This study also includes thresholds that categorise your pipeline efficiency into four categories: low, medium, high, and elite. 

The following table shows a more comprehensive representation of these metrics and its categories:

CI/CD pipelines have become indispensable tools for streamlining the process of delivering high-quality software at speed, directly impacting productivity, development velocity, and user experience (faster bug fixing leads to happier users).  

Ensuring that your pipeline processes produce the best outcomes is crucial in today’s fast-paced business environment. 

In the ever-evolving landscape of software development, CI/CD pipelines face numerous challenges in maintaining seamless automation. Based on my experience, teams frequently encounter difficulties in keeping their automation running smoothly. 

Challenges in CI/CD optimisation 

Despite the benefits of CI/CD pipelines, many organisations encounter challenges in optimising them for maximum efficiency. Some common hurdles include: 

• Complexity: As pipelines grow in complexity or numbers, managing dependencies, orchestrating tasks, and troubleshooting issues becomes increasingly challenging. 
• Visibility: A lack of visibility into the pipeline stages, metrics and status can lead to delays in identifying and addressing bottlenecks or failures. 
• Resource management: Optimising resource allocation and utilisation across multiple projects and teams can be complex without centralised control and monitoring. 
• Onboarding: New team members often face steep learning curves when joining projects with intricate CI/CD pipelines, highlighting the importance of comprehensive documentation and onboarding processes. 

Internal Developer Portals to the rescue 

Internal Developer Portals (IDPs) offer a robust solution to many of the challenges faced by organisations in optimising their CI/CD pipelines.  

Here’s how IDPs can help overcome common hurdles: 

Complexity 

IDPs simplify this process by providing a centralised platform that integrates various tools and services. This integration streamlines workflows, making it easier to manage and coordinate complex tasks. IDPs often come with built-in automation and orchestration capabilities, reducing the manual effort required to maintain and update pipelines. You can configure your CI/CD pipelines by the tasks they are built for and reuse them across multiple repositories. In some CI/CD orchestrators, you can reference a common pipeline, providing great flexibility: optimising one change and making it available for use across all your workloads. 

Visibility 

IDPs enhance visibility by offering comprehensive dashboards and real-time monitoring tools. These tools provide insights into every stage of the pipeline, enabling teams to quickly pinpoint issues and monitor performance metrics. Enhanced visibility ensures that teams can proactively address problems, leading to more efficient and reliable pipeline operations. 

Resource management 

IDPs centralise resource management, allowing organisations to allocate resources more effectively. They provide a unified view of resource usage, making it easier to identify underutilised assets and reassign them as needed. This centralised approach ensures optimal utilisation of resources, reducing waste and improving overall efficiency. 

Onboarding 

IDPs can facilitate smoother onboarding by providing standardised environments and configurations. With one-click configuration, developers do not need to worry about deployment details. The deployment process for a piece of software is defined once and can be used multiple times. 

Conclusion 

Adopting IDPs presents a transformative opportunity for optimising development processes and enhancing productivity within organisations. By standardising the approach to software development, particularly in the management of CI/CD pipelines, IDPs streamline the deployment of changes across projects and provide standard metrics that, without using IDPs, would need to be embedded in each pipeline individually to ensure proper instrumentation.  

This standardisation not only accelerates the implementation of improvements but also fosters a culture of continuous enhancement.  

Through IDPs, organisations can effectively navigate the complexities of modern software development at scale, achieving significant time savings, increased development velocity, and reduced time-to-market.  

As the digital landscape continues to evolve, embracing IDPs emerges as a strategic imperative for organisations seeking to remain competitive and agile in today’s dynamic market.
