Shifting Quality to the Left?

Shifting Quality Left: Why It Matters and How to Do It


The software development process is constantly evolving, and with each new change, there is a need for better quality control. One of the latest trends in software development is shifting quality left, which means focusing on quality from the beginning of the software development life cycle (SDLC). This approach aims to prevent defects from happening in the first place rather than finding and fixing them later.


Why Does Shifting Quality Left Matter?


Traditionally, quality assurance (QA) teams were responsible for testing software after it was developed. However, this approach can lead to a number of issues, including:

  • Longer testing cycles that can delay the release of software

  • Increased costs associated with finding and fixing defects later in the SDLC

  • Reduced quality due to time constraints and the need to meet deadlines

  • A lack of collaboration between developers and QA teams, which can lead to a siloed approach to software development

By shifting quality left, development teams can address these issues by:

  • Identifying and addressing defects earlier in the SDLC, which reduces the time and cost associated with fixing them later

  • Creating a culture of collaboration between developers and QA teams, which fosters innovation and ensures that everyone is working towards a common goal

  • Ensuring that quality is built into the software from the beginning, which improves overall quality and reduces the risk of defects occurring in the first place



How to Shift Quality Left


Shifting quality left requires a change in mindset and a focus on quality throughout the entire SDLC. Here are some steps to take to shift quality left:

  1. Start with a quality plan: Develop a plan that outlines how quality will be built into the software development process from the beginning. This plan should include processes for testing, quality control, and defect prevention.

  2. Focus on collaboration: Encourage collaboration between developers, QA teams, and other stakeholders from the beginning of the SDLC. This includes involving QA teams in the planning and design phases and encouraging developers to take ownership of quality.

  3. Use automation: Automation can help to streamline the testing process and reduce the time and cost associated with finding and fixing defects. This includes using tools for unit testing, integration testing, and automated regression testing.

  4. Use agile methodologies: Agile methodologies promote collaboration, flexibility, and a focus on delivering value to customers. By adopting agile methodologies, teams can shift quality left by testing early and often, and by incorporating feedback from customers throughout the SDLC.

In conclusion, shifting quality left is an important trend in software development that can help to improve quality, reduce costs, and increase collaboration between developers and QA teams. By adopting a quality-focused approach from the beginning of the SDLC, software development teams can ensure that they are delivering high-quality software that meets the needs of their customers.
