What is the step-by-step process for manual testing?

Excuse me, could you please elaborate on the step-by-step process for manual testing? I'm particularly interested in understanding the initial planning phase, including identifying the test objectives and defining the scope of the testing. How does one proceed from there to create test cases and design the test environment? Also, what are some best practices for executing the tests and documenting the results? I'm keen to ensure that the process is thorough and effective in identifying any potential issues or defects.
