As per an observation by McKinsey Research, DevOps can cut SDLC from 89 days to 15 days. Through collaboration and automation, software can go live in less than 20% of the original time.
DevOps has facilitated collaboration across the departments of software product engineering in following three main ways:
1. Structuring Teams to be Cross-Functional
It is a common observation that team members communicate well among themselves. If the team has experts across the entire software delivery cycle, operational silos would be automatically broken.
A basic structure for a cross-functional software development team would comprise developers, testers, analysts, and database administrators. Each team member would contribute a code to the version-control or can modify a part of the software as per their assigned task.
In contrast, a siloed team would have only developers or testers with their own ways to deliver on a task. Such isolated teams are inefficient in inter-team communication and take longer to address an issue that requires collaboration. A DevOps team is focused on delivery and is evolved enough to tackle each issue as its own.
2. Employing Automation Tools
DevOps implementation in software product engineering demands efficient sharing of resources like information on framework or language used in product design. Communication tools like Slack, Planning Tools such as JIRA, Ticketing Tools like Confluence, and Automation tools like Docker or Puppet have filled in the gaps to enhance the collaboration between the teams.
Apart from enhancing collaboration, DevOps tools have made individual processes more reliable and transparent. Any work that is likely not to be the part of the final product or is not up to the defined standards is eliminated through continual checks or automation tools.
In a DevOps transformation, McKinsey observed that there is almost a 50% decrease in the number of handoffs. DevOps efficiently reduces wait-time and unnecessary rework.
Due to multiskilled resources, specialist silos in software product engineering are broken. Any resource who is authorized to perform deployment can deploy the code or stop integration when needed. Versioning all artifacts like code, infrastructure or configuration helps in isolating changes and integrated change management prevents unnecessary rework.
Final Thoughts
Adopting DevOps model requires a systemic change across the organization. Such changes alter the whole IT value chain and not just the developers or testers. This reorientation requires careful planning to encourage cross-functional teams while balancing out the siloed functions during the transition.
It is also important to understand that DevOps is methodology to enhance the efficiencies but it can’t redeem an already inefficient process whose challenges are bigger than siloed teams.
