A Closer look at release management: How it works and why it matters
Release management has always been a vital component in the software development lifecycle, serving as the gateway through which new features and updates reach the end-users. However, with the advent of digital transformation, the landscape of release management has undergone a substantial transformation.
A Glimpse into the evolution of release management
Shifts in Release Dynamics
Reduced Release Sizes: The digital age mandates a transition from the waterfall, project-centric models to agile/DevOps, product-focused approaches. This shift results in the transformation of hefty batches of requirements into smaller, more manageable flow items.
Increased Release Frequency: Smaller release sizes enable more frequent deployments, fostering an environment that is conducive to experimentation and rapid feedback loops. This paradigm shift ensures that any misalignments with customer expectations are promptly identified and addressed.
Automation: The past reliance on manual efforts for releases is now mitigated with the availability of end-to-end automation across all release processes. Automation tools like Plutora have emerged, reducing the reliance on individual scripts ('script monsters') and mitigating the risks associated with Single Points of Failure (SPOF).
Ensuring Continuous Integration
Continuous integration (CI) has become a cornerstone in modern release management, ensuring that software is perpetually in a state ready for deployment. This is achieved through trunk-based development and continuous testing, where code integrations and tests are performed regularly, minimizing integration challenges and ensuring consistent quality.

With Plutora serving as both a release management and value stream management platform, teams are empowered to analyze and optimize their release processes, leading to improved time-to-release, enhanced value delivery, and enriched learning experiences.
Adapting IT Service Management (ITSM)
Traditional ITSM, inclusive of release and change management processes, requires adaptations to meet the heightened demands for speed and frequency in releases, a critical component in maintaining competitiveness in today’s disrupted market landscape.
Navigating challenges with release management
Facilitating Speed and Reducing Burnout
The drive towards faster and more frequent releases can inadvertently lead to an uptick in incidents, necessitating release activities during nights and weekends. This, in turn, can result in burnout among technology delivery teams. Effective release management addresses these challenges, reducing the occurrence of change failures, alleviating the workload on teams, and enabling them to focus on value-additive activities such as addressing technical debt and enhancing delivery platforms.
Ensuring Customer Satisfaction and Organizational Performance
Release failures extend their impact beyond internal teams, affecting end-users and, subsequently, the organization’s reputation and performance. Poor user experiences can lead to decreased usage, as well as challenges in customer retention and acquisition.
