You're faced with software updates. How do you balance new features and system stability?

When you're faced with software updates, balancing new features and system stability can be challenging. To ensure a harmonious blend, begin by assessing user needs through surveys and feedback analysis. 1. Choose features that will benefit users the most -- How do you determine which features users will benefit from the most? -- What can you do to minimize potential problems from new features? 2. Look for any potential issues before making updates -- What are the important steps in checking for risks with updates in existing functionality? -- How can you find and address potential issues early means before updating? 3. Also, we need to cover the steps, how can we effectively monitor performance during each rollout phase?

The business requirements may or may not align with user demands, to ensure that the new feature is adding value; some key points that need to be assessed are: 1. Does the new feature solves a problem which will save manual actions by users? 2. Does the new feature provide ease of usage for users without compromising the stability of the product? 3. Does the new feature complements the existing features of the product? 4. Can the new feature be utilized in other areas of the application? 5. Will the new feature comply with the agreed performance benchmarks?

Rigorous testing is essential for balancing new features and system stability in software updates. You can start by developing a comprehensive testing plan including unit, integration, and system tests. 1. First, we need to create a detailed testing plan that Includes different types of tests: small parts (unit tests), how parts work together (integration tests), and the whole system (system tests) 2. You can also manage automated testing within CI/CD pipeline. Implement automated tests to expedite the process and ensure consistency in execution. You can use Apache JMeter, SonarQube, Browserstack, CircleCI, and many more to ensure the speed and efficiency of software and to detect the bugs without any human interaction.

Once a new feature is released, during the warranty phase; KPIs need to be agreed upon and monitored to assess the success of the feature. Metrics which can be utilized are: 1. Agreed upon exceptions report for failures because of addition of new feature. 2. Performance metrics evaluation not just for the feature, but for the whole application as sometimes devil lies in the details. 3. Feedback from users who are using the feature to identify the scope of improvement. 4. Active monitoring of key metrics which can be used to identify the success of the release.
