Quality Assurance is everyone’s responsibility in an organization. A robust QA system is very important for tech teams. When deploying a new technology, product or any new services to the market without being carefully tested, it could cause irretrievable damage to customer trust and business brand. 

A Robust QA process in place is very critical to deliver a good quality product. Below listed are some best practices:

• QA Processes should be a Top-Down Effort
  Quality assurance is one of the most critical processes and the top management should prioritize this and ensure good QA practices and culture are built and monitored. QA is more likely to be effective when it is prioritized at all levels of the organization.

• Clear Processes should be defined for The Team
  Quality assurance is a process of building “in-process verification points” to prevent    quality failures. Defining clear objectives, creating strong and concise control points/checklists, and ensuring the team follows the defined path, conducting periodic reviews, and understanding the customer’s perspective throughout are crucial.

• Start the Process Early – Having QA processes in the earlier phase will lead to lower costs in the later phase. A defect that is removed after the product has gone into production will cost around 100 times more than one that is identified and removed during the requirements phase. Quality goes hand in hand with user experience. A quality product needs to empathize with the user—that is the key to success.
• Leverage Automation- Automation should be used as much as possible, tech leads should find the automatable areas in their testing process and implement automation practices that will effectively reduce QA time. Having the right skilled resources, tools and capabilities and effectively using automation will go a long way toward increasing the productivity of QA teams and reducing defects and improving the time to market.
• Cross Functional Collaboration – Collaboration is an important component of quality assurance. Having engaged, cross-functional teams can help each other in becoming champions ofQuality Assurance.
• Have A System Of Continuous, Integrated Quality Control – Having a modern QA approach along with good developers, DevOps and QA teams, tied with integrated tools and systems will help in continuous quality control. 
• Document And Test Every ‘Fix’ – Often developers come across odd behaviors in code and create stealth fixes to change the behavior which is actually right, in such cases documenting the changes is very critical, QA can design test scenarios and ensure the changes they made were truly broken before the change was made. Even Small changes can have huge unintended consequences.
• Implementation of a scalable approach
  Crowdsourcing is a very efficient way to expand our testing resources to improve usability and functionality of our applications- this process uses a distributed temporary multiple individual testers. So instead of expanding your team, have a team to complete the functional exploratory testing in the earliest phases and then scale up using crowdsourcing close to the release
