Any business today aims at achieving faster time to market with quality products or services. This is needed to stay competitive as rivals can threaten to lure away customers by offering better user experience. Hence, to stay competitive and achieve ROI, businesses are increasingly looking at embracing DevOps. The main objective of the development team is to rapidly create software with new features to address the changing market dynamics and customer preferences.
At the same time, the operations team aims at maintaining the stability of applications and be responsive to customer feedback. Since change can impact the stability of an application, the development and operations teams should work in unison to manage it. DevOps calls for bringing about a culture change by breaking the siloes between departments and ensure better collaboration and communication.

However, more often than not, the hallowed objective of effecting a culture change does not take place satisfactorily. In fact, there is often a slip between the cup and the lip as departments are found to be wary of letting others into their turfs. The transformation that DevOps seeks should have the support of technology and every stakeholder. Businesses should be well aware of the risks that demanding users can have with respect to the addition of new features. Let us understand the key factors needed for successful DevOps implementation.
- Agile over waterfall: Businesses should embrace Agile methodology comprising shift-left testing that enables focused, smaller, and iterative process of development. This reduces the potential risks with the software and ultimately, for the end-user.
- Better communication and collaboration: The members of development and operations teams should have a unity of purpose. They should have a proper understanding of the requirements and ensure proper coordination to meet them.
- Automation: This is the key to achieve a successful DevOps testing whereby every change in feature is validated for performance, functionality, security, and integration, among others.
Even though DevOps has been accepted as a game-changer as far as improving the quality and achieving the quick delivery of software are concerned, there are myths galore. This is due to the fact that DevOps does not have a proper definition, but several explanations. This often results in situations where different people derive different conclusions about similar practices, tools, or ideas. Here are some of those myths.
DevOps Process Changes from Project to Project
DevOps, and by corollary, DevOps testing, is about applying a set of procedures across multiple projects. This allows for a better understanding of the roles and responsibilities of team members across departments. So, there is no need to reinvent the wheel for every project as it goes against the grain of DevOps. The DevOps test automation process ought to be flexible so that it can adapt to the server configurations, deployment cycles, and team strength. This can only happen when there is a deep understanding of the process enabled through repetition.
DevOps Is Only About Automated Tools
You cannot buy DevOps like you would buy an automated tool. DevOps is the methodology to deploy and monitor the quality of applications. Its outcomes viz., continuous delivery, continuous integration, and continuous testing are not automated tools but the result of well thought out practices. Yes, automated tools are needed to implement DevOps. These include names such as Selenium, Docker, CircleCI, GitHub, and Chef, among others. However, the efficacy of these tools can only be achieved if the teams using them know how to optimize and leverage them.
DevOps Is Similar to Continuous Delivery
Continuous delivery happens to be one of the key components of the DevOps testing strategy but is not DevOps in its entirety. The focus in implementing DevOps should be more about improving the culture of the teams entrusted with the development, testing, and maintenance of software.
DevOps Only Applies to Successful Start-Ups or Unicorns
Although unicorns may have tasted success by adopting the DevOps philosophy and applying continuous improvement, integration, testing, and delivery of software, they have mostly predated the advent of DevOps. So, companies like Facebook, Amazon, Twitter, and others are said to follow DevOps principles of investing more in people vis-a-vis tools or processes.
DevOps Is Just About Better Communication Between Developers and Operation Managers
Even though communication plays an important role in the success of DevOps, it is not everything. DevOps is more about understanding every element of the process by experts. So, when a team of technical experts is integrated into the DevOps pipeline, it should result in a flexible and scalable process.
The myths surrounding DevOps stem from an inadequate understanding of its methodology. It is an overarching principle that can deliver huge benefits for companies. By implementing iterative DevOps testing, bugs can be quickly identified at the outset and software application better tuned to the market demand.
