GM, or the goals, questions and metrics is the method used. Goals are set, questions are asked about what improvements can be made and metrics (measurements that tell us something about the process) are carried out.

The tool commonly used for arriving at improvements in processes in the context of project management is a “Process Improvement Tool” or “Process Improvement Methodology.” There are several methodologies and tools available, such as:

Six Sigma: A data-driven approach to process improvement aimed at reducing defects and variations in processes.
Lean: Focuses on maximizing value while minimizing waste within a process.
Kaizen: A continuous improvement methodology that emphasizes making small, incremental changes over time.
PDCA (Plan-Do-Check-Act) Cycle: A systematic approach to problem-solving and process improvement.
Root Cause Analysis: A technique used to identify the underlying cause of a problem or issue within a process.

In an interview, it’s essential to mention the tool or methodology that you are most familiar with and have experience using, along with examples of how you’ve applied it to achieve process improvements in your previous projects. Additionally, demonstrating an understanding of how these tools align with organizational goals and project objectives can showcase your expertise in project management.
