Software Tester - Best Practices

(a)Performing a domain knowledge transfer (DKT) to the team with regards to the data collected.
(b)Analyzing how the issues can be sorted out in the code level review for application performance.
(c)Ordering test strategies & test selection techniques ought to be prioritized.
(d)Reviewing UX/UE documents.
(e)Scheduling the prerequisite for a project before the requirement scrutiny starts.
(f)Sheltering the success with the testing process/methodology which is been applied.
