3. Scientific Method Analysis HypothesisSynthesis Validation

4. Objectives Objective of Validation phase is To decide whether the objective of the task has been achieved Based on formal conclusions And rigorous peer review

5. Compute Performance Reduced results in Synthesis Scientific Method stepwise refinement Performance metrics may need to be revised if Not suitable Do not validate hypothesis
