Enterprises are embracing digital transformation to deliver high-quality products and services to their target customers at a faster rate. This is an important step in the right direction as such enterprises are likely to add economic value to the tune of 14 trillion pounds, as per IDC, the market intelligence firm. However, digital transformation needs the application of proper tools, methodologies like DevOps, and a culture change in the organization. A key enabler of digital transformation is the practice of shifting the testing cycle early in the development pipeline aka ‘shift-left’. This shift left approach in DevOps ensures the delivery of security and quality on a continuous basis throughout the SDLC. 

Why is shift-left testing important for digital transformation?

In conventional manual testing, applications are tested after development. Since development teams generally get the leeway to work till the eleventh hour, the testing team is given very little time to complete testing. As testers work manually, they get little choice but to adhere to the stringent delivery timelines. This hurried job of testing often results in delivering a substandard product and a bad customer experience. Later, the development teams need to work on the product after customers highlight quality issues resulting in cost escalation.

Today, customer satisfaction has become the number one objective for enterprises and with the presence of defects, achieving this objective gets derailed. Also, if the defects are related to security issues then there is a likelihood of the company attracting heavy penalties, legal suits, and censure. So, if the defects are addressed early in the value chain courtesy the shift left software testing approach, then the resulting damage can be minimized or prevented. All said and done, to let the shift-left approach work and deliver the expected outcomes, every team in the SDLC should be prepared to embody the change. In other words, besides embedding technical practices and the use of advanced tools, it is important to embody the shift-left culture by every team.

As most teams work in a siloed environment, merely prodding from the top and focusing on using automation tools and techniques are not going to deliver results. On the contrary, without embracing the shift-left ‘culture’, teams may face further consolidation of divisions. Hence, it is imperative to drive a cross-organizational culture in favor of the shift left digital transformation strategy. If the cultural and behavioral changes across teams are addressed beforehand, the shift left DevOps strategy has a greater likelihood of succeeding and delivering performance.

How to enable shift-left digital quality assurance

The practices to bring about a shift-left software quality assurance strategy are:

Culture change aligned to the company’s vision: Shift-left aims at empowering a business by embedding the testing process early on in the delivery pipeline. However, for the success of this transformation methodology, it needs buy-in from every stakeholder across the organization. To usher in this change, the first step should be to align everyone to the company’s vision. This will ensure that everyone in the value chain understands the big picture and their role in achieving the vision. For example, everyone should know about questions such as:

  • What should we do to deliver the best customer service?
  • How to ensure our company remains competitive?
  • How is our performance today and what changes are needed going forward?

       Teams to pursue a common goal: It has been observed that implementing a shift left QA strategy can significantly improve the company’s performance. The next step is to incentivize and reorganize the teams to break the silos and the resultant inefficiencies. This will drive agility through short iterative cycles across teams. An effective change management program educating teams about how the changes would radically help the company in achieving success can help matters.

Assessment of performance: After aligning the teams around the company’s vision and incentivizing them, the software delivery performance needs to be assessed and evaluated. The metrics to be analyzed in order to categorize performance and identify wastage are – frequency of delivery, change lead time, fix meantime, and change failure rate. Here, the first two metrics evaluate throughput while the other two measure stability. A successful shift left approach should focus on achieving both throughput and stability. 

Conclusion

With throughput and stability ensured, the shift left testing in digital transformation should look at implementing key technical practices involving environments, test automation, and behavior-driven development. This would ensure everyone in the value chain works together as a collective entity rather than as individuals.

Discuss Test Orchestration and its Role in Achieving Optimal Quality of Software

Image
  In the DevOps approach of developing, testing, and delivering software applications, there is a need to accelerate testing within the constraints of budget and time. This entails automating the testing process as part of the testing strategy. In many cases, continuous test automation is often considered as a discrete step in the build pipeline rather than a sequence of steps. For any continuous testing strategy, all software applications need to pass through a series of tests before they pass muster in the crucible of quality. These may include unit testing, integration testing, functional testing, smoke testing, performance testing, security testing, and others. For DevOps QA testing, each of these tests should be subjected to automation to enhance quality, reduce test time, and improve the certainty of software behavior. However, merely automating the tests left, right, and center does not augur well when it comes to achieving an optimal quality level as well as minimizing the ...

What is the Importance of Compatibility Testing for a Software Application?

Image
  Customers are wont to use software applications for various purposes across device platforms, networks, operating systems, and browsers. They expect the software applications to perform seamlessly irrespective of the digital environments. However, customer experience in real-time does not always achieve such performance causing disgruntlement. In an industry where new devices are launched with different configurations, and new versions of operating systems, frameworks, and browsers are released in a few weeks or months, ensuring the software application perform seamlessly across platforms can be a herculean task. Moreover, since it is practically impossible to evaluate each customer’s usage of a device, browser, operating system, or network, it is imperative to ensure the software application functions properly across digital environments. This calls for integrating compatibility testing in the SDLC. What is compatibility testing and why is it important? Compatibility testing...

How many Types of Mobile App Testing Services are there?

Image
  The utilitarian value of mobile phones has been mainly due to the plethora of applications that are accessed by users to perform a raft of activities. These may include watching movies, paying utility bills, booking tickets, playing games, reading informative content, and buying merchandise, among others. Does this mean users lap up every application on offer? The answer is an emphatic NO as users look for attributes such as fast loading time, enhanced security, seamless navigability, and many others. Even as businesses are aware of the need to employ mobile testing services and ensure the release of quality applications, the pressure to remain competitive often overrides such considerations. Statistics show that approximately 68.07 percent of mobile applications never reach 1,000 downloads (Statista). In other words, approximately 67 percent of mobile app developers do not make a profit. So, what is the way out and ensure the apps hit the bull’s eye of customers’ approval? It’s ...
