The need for Agile software delivery in manufacturing

The manufacturing sector is undergoing a major transformation driven by Industry 4.0 technologies. This shift has created a landscape where digital tools, smart factories, and data-driven processes define the competitive edge. For CIOs and CTOs of manufacturing companies, the challenge lies in integrating and scaling these technologies without disrupting production timelines or increasing operational risks. The margin for error is thin, and delays or inefficiencies can quickly erode profit margins and production quality.

One of the biggest obstacles manufacturing leaders face today is the sluggish pace of traditional software development and deployment cycles. In an environment where supply chains need real-time coordination, machines rely on continuous data feeds, and production schedules change dynamically, software delivery cannot afford to lag behind. Slow and rigid software deployment can result in downtime, production bottlenecks, or worse, a failure to keep up with market demands.

The imperative for speed and flexibility in Industry 4.0

To remain competitive, manufacturing companies must be agile, not only in their physical processes but also in their software infrastructure. The integration of digital tools like predictive analytics, IoT devices, and AI-powered automation demands an IT environment that can adapt and respond to these rapid technological shifts. Software updates and feature deployments need to be done quickly to keep pace with the evolving production requirements and the integration of new technologies.

Without agile software delivery processes, manufacturers risk:

• Prolonged downtime during software updates or patches.

• Delays in deploying new features critical for production efficiency.

• Higher likelihood of errors due to manual processes and lack of automation.

How DevOps aligns IT with operational excellence

DevOps offers a solution by unifying the traditionally siloed departments of development and operations. For manufacturing companies, this means tighter alignment between IT teams that develop the software and operational teams that ensure production lines run smoothly. DevOps enables continuous integration and continuous delivery (CI/CD) pipelines, which are essential for ensuring that software updates happen seamlessly and with minimal disruption to production.

By adopting DevOps practices, manufacturing companies can:

• Increase deployment frequency: Automating software releases through DevOps enables faster and more frequent deployments, ensuring that new features and critical updates are delivered without interrupting production.

• Reduce production errors: Automated testing and monitoring systems catch bugs before they impact the production floor, minimizing costly downtime and defective outputs.

• Enhance collaboration between IT and OT teams: Breaking down the silos between IT and operations fosters better communication and ensures that software deployments align with production schedules and operational needs.

In a competitive market where manufacturing agility is key, IT executives cannot afford the inefficiencies of traditional software development cycles. DevOps provides the framework needed to streamline software delivery, reduce errors, and adapt quickly to the demands of Industry 4.0, ultimately aligning IT with the goals of operational excellence.

The table below highlights key outcomes that 36,000 respondents of the Accelerate State of DevOps Report 2023 by Deloitte see as the result of efficient DevOps practices. They include organizational, operational, and team performance, reliability targets, as well as software delivery performance (which includes deployment frequency, lead time for change, change failure rate, and failed deployment recovery time metrics). The well-being of a team is also seen as a major key outcome of a properly implemented DevOps culture and is assessed as a composite of burnout, productivity, and job satisfaction.

What is DevOps? A primer for manufacturing leaders

As manufacturing companies increasingly rely on sophisticated software solutions to power their production processes, the traditional approach to software development often proves inadequate. Delays in deploying updates, inconsistent collaboration between teams, and a lack of automation all contribute to inefficiencies that can slow down manufacturing operations. This is where DevOps comes into play.

Definition of DevOps  

At its core, DevOps is a set of practices, tools, and cultural philosophies that aim to break down the silos between software development (Dev) and IT operations (Ops). DevOps fosters collaboration and automates processes, enabling faster and more reliable software delivery. For manufacturing environments, this means that critical applications, production control systems, and IoT platforms can be updated seamlessly without interrupting production or introducing errors.

In technical terms, DevOps combines continuous integration (CI) and continuous delivery (CD) to automate the process of integrating code changes, testing them, and deploying them to production. It also incorporates tools for infrastructure as code (IaC), enabling automated provisioning and management of the IT infrastructure that supports production. Monitoring and feedback loops ensure that any issues in the software are caught early, minimizing the risk of production disruptions.

Core principles of DevOps

Continuous Integration (CI) and Continuous Delivery (CD)

• CI refers to the practice of automatically integrating code changes from multiple developers into a shared repository, ensuring that the code is always in a deployable state. This is particularly valuable in manufacturing, where even minor software issues can have a direct impact on production.

• CD extends CI by automating the entire release process, ensuring that updates are delivered quickly and reliably to production environments. For manufacturing, this means minimizing downtime during updates and ensuring that new software features or patches are deployed without impacting production schedules.

Example:
In a manufacturing environment, CI/CD pipelines can ensure that software updates to production control systems are deployed without shutting down production lines, reducing costly downtime.

Infrastructure as Code (IaC)

• IaC is the practice of managing and provisioning infrastructure through code, rather than manual processes. In manufacturing, this allows IT teams to automate the setup and management of environments used for production, testing, and development.

• With IaC, infrastructure configurations are version-controlled, meaning that manufacturing companies can quickly replicate or scale their IT environments as production needs grow or change.

Example:
A manufacturing company can use IaC tools like Terraform or Ansible to automatically set up new server environments when scaling a production line, ensuring consistent configurations across all environments.

Automated monitoring and feedback

• DevOps places a strong emphasis on continuous monitoring of software systems in production environments. Automated monitoring tools can detect issues early, reducing the risk of software bugs affecting production workflows.

• Real-time feedback loops enable teams to react quickly to issues, further reducing production downtime.

Example:
A DevOps monitoring tool can alert a manufacturing team the moment an application issue arises, allowing IT teams to fix it before it affects machinery operations.

Collaboration and communication

• One of the most important cultural shifts in DevOps is the emphasis on collaboration between development, IT operations, and even operational technology (OT) teams. In manufacturing, this ensures that software developers and IT teams work closely with the operational side of the business to align updates with production needs.

Example:
Regular communication between IT teams and production managers ensures that critical software updates are deployed during non-peak hours, preventing disruption to production schedules.

Why traditional software development approaches fall short in manufacturing environments

In traditional software development models, the process of building, testing, and deploying software can take weeks or even months. This approach often relies on siloed teams, where development, testing, and operations work independently, leading to communication breakdowns and slower delivery cycles. In a fast-paced manufacturing environment, these delays can result in missed production targets, costly downtimes, and an inability to quickly respond to changing market demands.

Some of the major shortcomings of traditional approaches in manufacturing include:

• Slow software delivery: Updates and bug fixes take longer to reach production, delaying improvements or critical fixes to production systems.

• Higher risk of errors: Manual deployment processes increase the risk of human error, leading to potential production interruptions.

• Limited scalability: Scaling traditional IT infrastructure to meet growing manufacturing needs requires manual intervention, slowing down the process and introducing inconsistencies.

• Siloed communication: Disconnected development and operations teams result in misalignment between software updates and operational needs, further complicating production processes.

DevOps addresses these pain points by creating a seamless, automated process where updates are deployed frequently and with minimal risk of disruption. For manufacturing leaders, this means faster time to market, reduced operational risks, and the agility needed to stay competitive in an increasingly digital landscape.

In the context of Industry 4.0, DevOps is not just a technical practice—it is a strategic enabler that allows manufacturing companies to innovate faster, reduce operational inefficiencies, and ensure continuous alignment between IT and production processes.

Faster deployment cycles: Adapting to rapid production changes

In the manufacturing industry, the ability to rapidly adapt to production changes is a crucial competitive advantage. Whether it's adjusting to fluctuating supply chain demands, updating production line configurations, or integrating new technology, software plays an integral role in supporting these changes. Traditional software development methods, with their long deployment cycles, can no longer keep up with the rapid pace of modern manufacturing environments. This is where DevOps comes into play, enabling faster deployment cycles through Continuous Integration (CI) and Continuous Delivery (CD) practices.

How DevOps enables Continuous Integration and Continuous Delivery (CI/CD)

DevOps integrates development and operations teams, allowing for the automation of the entire software release process. In a manufacturing environment, this automation ensures that software updates are deployed quickly and reliably, without causing disruption to production processes.

Continuous Integration (CI) involves the practice of frequently merging code changes into a shared repository. Each code change is automatically tested, which ensures that bugs are caught early. This process is critical for manufacturing companies, where even a minor software glitch can disrupt production.

Continuous Delivery (CD) extends CI by automating the deployment of code changes to production environments. This means that software updates, patches, or new features can be delivered more frequently, and with significantly reduced downtime. The automation of deployment processes allows manufacturing companies to maintain high operational efficiency, as updates can be deployed during off-peak hours or in rolling batches that do not interfere with production.

Benefits of automated deployment in manufacturing

The automated deployment processes enabled by DevOps deliver significant advantages for manufacturing companies:

DevOps practices, with their focus on automation and continuous integration/continuous delivery (CI/CD), offer a solution by significantly reducing the likelihood of software errors. One of the most powerful tools within the DevOps framework is automated testing, which ensures that code changes are thoroughly vetted before being deployed to production environments.

The role of automated testing in reducing human errors in software deployment

Automated testing plays a critical role in improving the reliability of software by automating the repetitive and error-prone task of manual testing. This is especially important in manufacturing environments, where even minor software bugs can result in machine downtimes or incorrect production outputs. Automated testing allows for the continuous verification of code changes, ensuring that new features, updates, or patches do not introduce errors into production systems.

By automating testing, DevOps enables:

• Consistent and repeatable tests: Automated tests can be run as often as needed, ensuring consistent and repeatable results, which reduce the risk of undetected errors.

• Faster feedback loops: Automated tests provide immediate feedback to developers, allowing them to address issues early in the development cycle before they impact production.

• Reduction of human error: Since testing is automated, the chance of human error during the testing process is minimized, increasing the overall quality of the software being deployed.

How DevOps practices enable proactive error detection and faster fixes

One of the key benefits of DevOps is its ability to detect and resolve errors proactively, often before they impact production. This is achieved through automated testing, continuous integration, and real-time monitoring, all of which contribute to faster and more efficient error detection and resolution.

• Continuous Integration (CI) ensures that code changes are integrated frequently, allowing for early detection of bugs during the development process. Every time a change is made, automated tests are triggered, identifying potential issues before they are pushed into production.

• Automated regression testing helps ensure that new code changes do not break existing functionality. This is crucial in manufacturing, where software systems often interact with complex production equipment and processes.

• End-to-end testing pipelines provide comprehensive testing across all stages of the software development lifecycle, ensuring that software behaves as expected in real-world production environments.

• Real-time monitoring and feedback loops allow IT and operations teams to monitor the performance of production systems in real-time. Any anomalies or errors can be detected immediately, enabling quick fixes before they escalate into major issues.

‍Common testing automation tools and strategies in DevOps

To fully leverage DevOps and automated testing in manufacturing, companies need to implement the right tools and strategies. Below are some of the most commonly used tools and approaches:

DevOps practices not only improve the speed and efficiency of software delivery but also enhance the overall quality and reliability of manufacturing systems.

Improved collaboration between IT and operations (OT): Breaking down silos

In manufacturing environments, the divide between IT (Information Technology) and OT (Operational Technology) teams can lead to inefficiencies, miscommunications, and delays in implementing critical software changes. Traditionally, IT teams focus on managing the software infrastructure, while OT teams are responsible for the hardware systems that control the physical manufacturing processes. However, as factories become more digitized and reliant on interconnected systems, collaboration between these two teams is essential for seamless operations.

DevOps plays a pivotal role in breaking down the silos that traditionally exist between IT and OT by encouraging cross-functional collaboration and communication. This alignment ensures that software development and operational requirements are continuously in sync, resulting in more efficient production processes and fewer bottlenecks.

Bridging the gap between IT and operational technology (OT) teams in manufacturing

In a typical manufacturing setup, the OT team manages production machinery, sensors, control systems, and other hardware that keep production running smoothly. The IT team, on the other hand, handles the software applications and platforms that support these systems. When these teams operate in silos, the disconnect can lead to:

• Misaligned priorities, where software updates are not aligned with production schedules.

• Delays in deploying critical updates due to communication breakdowns.

• Increased production risks from incomplete or improperly tested software changes.

DevOps provides a framework for bridging this gap by fostering a culture of collaboration between IT and OT teams. In DevOps, both teams work together throughout the software development and deployment processes, ensuring that software changes are aligned with operational needs and that production can continue without disruption.

How DevOps fosters cross-departmental collaboration and communication

At the heart of DevOps is a commitment to breaking down silos through shared responsibilities, frequent communication, and joint problem-solving. By involving OT teams early in the development process, IT teams can better understand production requirements and ensure that software updates are tailored to operational needs. Likewise, OT teams gain more insight into how software changes can enhance or affect production processes.

DevOps achieves this through:

• Shared goals and metrics: DevOps encourages the creation of shared objectives between IT and OT teams. This can include metrics such as uptime, production efficiency, and deployment success rates.

• Frequent communication: Tools like Slack and Jira allow for constant communication and collaboration between teams, enabling faster decision-making and reducing the risk of misalignment.
