1 Article for the Week:
Value Stream Mapping (VSM) and Time Study are both important for improving
processes, but they serve different purposes. VSM looks at the entire process to find
and fix inefficiencies. Time Study focuses on measuring the time needed for specific
tasks. Understanding these differences helps in choosing the right tool for better
efficiency.
1. Focus
Time Study: Time Study focuses on measuring and analyzing the time
required for specific tasks or activities
VSM: VSM focuses on mapping the entire process flow and identifying
inefficiencies across the value stream
2. Scope
Time Study: Time Study focuses on individual tasks or operations
within the process
VSM: VSM covers the entire value stream from start to finish, including
every step involved in producing a product or service.
3. Methodology
Time Study: Time Study involves direct observation or measurement
of time spent on tasks to establish standards and improve efficiency
VSM: VSM uses visual mapping and analysis of process flows and
metrics like lead time, cycle time, and inventory levels
4. Output
Time Study: Time Study provides quantitative data on task times to
optimize specific tasks or operations
VSM: VSM provides visual maps and identifies improvement
opportunities across the entire process
5. Application
Time Study: Used for detailed task analysis, setting performance
standards, and optimizing specific operations. Common in industrial
engineering and process improvement for individual tasks.
VSM: Used for overall process improvement, waste reduction, and
strategic planning. Ideal for Lean initiatives to enhance the entire value
stream.
Tools used
Time Study: Stopwatches, time study software, and motion analysis
tools.
VSM: Flowcharts, process maps, swim lane diagrams, and VSM
software

“The Toyota style is not to create results by working hard. It is a system that says
there is no limit to people’s creativity. People don’t go to Toyota to ‘work’ they go
there to ‘think’.” - Taiichi Ohno
“I say an hour lost at a bottleneck is an hour out of the entire system. I say an hour
saved at a non-bottleneck is worthless. Bottlenecks govern both throughput and
inventory.” - Eli M. Goldratt
