Developer perspective of a technology

For a developer to understand technology, best way according to me is Algorithmic approach. Which is
  1. Identify the problem being solved by the technology. Prepare a problem statement out of it. Have Test cases with Expected Input and Output.
  2. Think technology which is solving that problem as an algorithm. Analyze all the pros and cons of an algorithm.
  3. Understand the algorithm. Go through the source code. Validate the algorithm
  4. If possible think of better approach of an algorithm. Refactor algorithm until it is efficient.
  5. Explain the algorithm clearly end to end.
  6. Implement the algorithm
  7. Write and execute test cases to certify the algorithm.
  8. Find patterns in the algorithm and generalize the algorithm.
  9. understand where all it can be used. Apply the algorithm to solve other problem statements.
