Organizations are under pressure to provide high quality software products in a shorter time span due to fast development of software technologies. The sequential model of inspecting and correcting faults is usually done at a later stage in the development and hence results in long project time, higher costs and low quality products. To tackle these issues, there has been a development of shift left approach which is a practice that focuses on testing right from the beginning in the development cycle and integration of feedback along the process.In shift left the testing and security checks are done at the same stage where the requirement is defined, or it is done during the design stage if the requirement is done at the same stage where the requirement is defined. This is a form of preventive approach which intends to have problems solved when they are still discovered at early stages of the cycle as this will help prevent so many problems from arising in the later days. In this blog, we will explore the concept of the shift left approach, its role in DevOps and DevSecOps, and how organizations can build an effective shift left strategy to enhance their development processes.

Understanding the Shift Left Approach
The shift left approach is a concept that emphasizes the importance of moving certain tasks, traditionally performed at later stages of the software development lifecycle, to earlier phases. This proactive strategy aims to catch defects, vulnerabilities, and other issues before they become significant problems, ultimately improving the quality and speed of software delivery.
What is the Shift Left Approach?
The shift left approach involves the effort of performing testing, security evaluation, and other similar processes at the early stages of application development. The expression “shift left” originates from the idea of shifting these tasks towards the left part of the mentioned traditional straight project timeline where design and development tasks belong to. This way, these activities are performed earlier. Teams can identify and fix problems earlier on, allowing for shorter development cycles and higher quality software.
The Role of Shift Left in DevOps
The shift left approach is particularly relevant in the context of DevOps, where the focus is on continuous delivery and integration. By incorporating shift left practices, DevOps teams can enhance their processes, reduce cycle times, and deliver higher-quality software more efficiently.
Integrating Shift Left Approach in DevOps
In a DevOps environment, the shift left approach aligns closely with the core principles of collaboration, automation, and continuous improvement. In this way, modular elements of a software can shift the testing and security checks to the early stages of the development process, thus accelerating the integration of testing and security teams with development teams in order to minimize the division between them.
Applying the shift left approach in DevOps means changing culture in an organization. It must always be the responsibility of all the team members to insist on constant testing and evaluation of quality. It leads to tighter interaction between the development, operation and security teams resulting in a faster feedback loop that is used for the identification of the problems and their rectification. As a result, the overall development process becomes more efficient, and the final product is of higher quality.
DevSecOps Shift Left: Enhancing Security Early
As organizations are realizing the importance of integrating security into their development processes, the concept of DevSecOps has gained traction. DevSecOps extends the principles of DevOps to include security, ensuring that security practices are embedded throughout the software development lifecycle. The shift left approach in DevSecOps plays an important role by moving security activities to the earliest stages of development, thereby reducing vulnerabilities and enhancing overall security.
The Need for Shift Left in DevSecOps
With the traditional model for software development, security becomes an add-on feature, which is implemented only after the code is written and is prepared for execution. Such an approach creates possibilities of deeply rooted critical security flaws being detected near the end of projects leading to drastic changes and other financial losses halting the security of the final product.
The adoption of DevSecOps shift left approach eliminates this problem by ensuring that security activities are integrated in the development lifecycle at the early stage. By shifting left, the security is integrated and becomes an underpinning activity in the system development life cycle. It also creates awareness of developing a security plan to fix any probable vulnerability before it is coded into the system.
Building a Shift Left Strategy: Best Practices
When it comes to the shift left approach, organizations need to ensure they have a proper plan for adopting agile and adapting the practices throughout software development. Thus, shift left is not only about technology but is also about organizational culture and methodologies that can make quality assurance from day one a regular practice.
Creating a Shift Left Culture
To create the shift culture, organizations need to change the development culture and focus on integrated teamwork, which involves developers, testers, security personnel, and operations personnel. It is vital to foster communication and assign tasks to all concerned parties and to stress that early testing and security integration are important to the project.
Also, on-going training and staff development are crucial for the shift left approach to be effective. Everyone on the team should be empowered with knowledge on how to integrate testing and security into their activities. This might include first-time training to use automated testing tools, understanding security procedures and norms or other approaches that can be implemented to enhance early problem identifying phases.
Challenges and Solutions in Adopting Shift Left
While the benefits of the shift left approach are clear, implementing it is not without challenges. Organizations must be prepared to address these challenges to ensure a smooth transition and to fully realize the benefits of the shift left approach.
Common Challenges in Shift Left Implementation
- Resistance to Change:
– Teams used to traditional development processes may resist adopting new practices, especially when significant changes to existing workflows are required.
– This resistance is often due to a lack of understanding or awareness of the benefits of the shift left approach.
- Initial Investment:
– Implementing shift left practices requires upfront costs, including purchasing new tools and allocating time for training and upskilling.
– Smaller organizations may find it particularly challenging to manage these initial expenses.
- Complexity of Integration:
– Integrating new tools and practices into existing workflows can be complex and time-consuming.
– Ensuring that all team members are aligned and that new tools are properly configured and utilized adds to the challenge.
Overcoming Obstacles in Shift Left Adoption
To overcome the challenges posed in the shift left model, organizations should work to create an open culture in the development phase. The following can be done to facilitate the shift to the left: This can be done by explaining to everyone the advantages accruable to the adoption of shift left approach and by making all the members of the team to be part of the planning and implementation process. It can also help to minimize resistance by making sure that people are trained to use the new tools and practices that are expected of them properly all the time.
In regard to the management of the initial investment, there is no need for an organization to go for a full implementation at once. Here, people should also remember that implementing shift left does not need to begin with a complete change in an organization’s approach to development, but instead, it can happen step by step, starting with a pilot project or one stage of the development process and gradually transitioning from there while saving money in case the experience turns out to be less positive.
Here, the issue of complexity arises and thus there is need to advise that organizations should aim at selecting tools that fit well in the organization’s infrastructure as well as working processes. It is also a good practice to follow up with the team to guarantee that all of them are at ease with the changes and know how to go about using the new tools and the respective procedures. In this way, it becomes possible to follow the shift left to efficient adoption and overcome all the challenges mentioned above.
