What are the best ways to ensure high-quality software delivery as a team lead?

Defining clear requirements is key for building solutions and one of key process to follow is implementing review with cross functional teams across Dev and QA teams to find any gaps or ambiguity in requirements. Indenting testable and non testable requirements will help to implement quality solutions

Before you start applying a coding practice, it's better to understand its pros and cons and underlying ideas. Most of the time, it won't be necessary to implement it 100%. In my experience, I picked the things that resonated in the current context. Otherwise, it may be a significant overhead.

One thing I have found helpful is to set an expectation that each unit of code to be reviewed - a pull request, for example - contain only one unit of work. Separate bug fixes from features from refactoring. Unit tests can be better targeted, rollback is less dangerous, and the biggest saving is lowering the load for high quality reviews when the purpose of a change is clearer.

The goal of writing automated tests is not to achieve a 100% pass rate. The goal of writing automated tests is to get information about any deviations from the expected behavior you codified in those tests in a fast and reliable manner. End-to-End tests are the only type of test that proves the system works. Of course, the other types of tests are useful, but the most valuable are the end-to-end tests. E2E tests are the only type of test that gives me complete confidence that the feature actually works.

Testing plays key role in delivering quality solutions to business, it is start with requirement analysis to check testability and will help preparing approach for testing. Automation 1st approach is best to improve test coverage and efficiency in execution but to focus only on critical business process and avoid everything to automate to get best value out of automation.my experience is engaging QA in initial phase of project plays major role in overall success of project. QA approach should focus on both Functional and nonfunctional testing along with positive and negative scenarios. Delivering quality solution is every on one responsibility not just QA start with business providing clear requirements and dev team to build right solution

Build strong Engineering Excellence culture and. make product testing a part of the engineering expectations. Building a product requires the person involved to have full ownership of the e2e process. Similarly teams that deploy certain services or products to production would be on call if anything fails. This way if a feature is broken or not performing as expected they own the problem and responsibility of fixing it.

In the thrilling journey of software development, the compass that points straight to success is the habit of testing early and testing often. Diversity is key in the testing world. Never settle for just one type of testing; variety is the spice that enriches our journey. Unit testing, integration testing, system testing, and the grand finale - user acceptance testing - each acts as a layer of defense, ensuring our code gracefully navigates through different scenarios and altitudes. Testing is more than a mere process; it's a mindset. It's the recognition that perfection is a continuous journey, not a static destination. Embrace the learning curve, for each bug uncovered is a step closer to the software nirvana we strive for.

This sounds like Continuous deployment. It's better to say the definitions in the software development clearly than giving vague idea.

I've found publishing Draft PRs for more complex changes beneficial so we can easily discuss them and address issues in advance. This way, the person making the change can gather additional feedback. Then, reviewing the ready PR is much easier. I would also add that it's better to put all the communication regarding the PR in the PR as comments so every team member knows why specific actions have been made.
