Study Notes

Learning Outcomes

Implement waste minimization techniques in the engineering workplace.
Make improvements to workplace organization using a workplace scan.
Employ methods of visual management in the engineering workplace.

Lean Six Sigma Approach

A team-focused managerial approach that seeks to improve performance by eliminating resource waste and defects, as well as deviations from standards.
5 steps for Six Sigma:
- Define the problem: Craft a problem statement, goal statement, project charter, customer requirement, and process map.
- Measure the current process: Collect data on current performance and issues, verify data reliability, and update the project charter as needed.
- Analyze the cause of issues: Examine the process and data, display the data, investigate and confirm the issues, and continue updating the project charter as needed.
- Improve the process: Decide on solutions to fix issues, create process maps for new solutions, and implement the new fixes.
- Control: Refine the new process, continue monitoring, and use findings elsewhere in the business if possible.

5S Technique

5 benefits of a 5S system:
- Create space within the facility by removing unnecessary tools and equipment.
- Reduce downtime and improve quality by consistently maintaining equipment.
- Reduce waste from unnecessary motion by organizing the workspace.
- Engage operators by granting them more responsibility for their work environment.
- Create a safer work environment by ensuring it is clean and well-maintained.

5S Steps

SORT

Separate items in the workspace that are needed from items that are not needed or may not be needed.
Move unneeded items to a "red tag" holding area.
Reasons to sort: remove unneeded clutter, eliminate distractions, and open up space for other uses.
Items to sort:
- Items needed in this work area.
- Items needed in another work area.
- Items you may need (use the 5S "red tag" system).
- Items you do not need (discard, recycle, or donate).

STRAIGHTEN (Set to Order)

Thoroughly organize the items that remain after sorting, making frequently used items easily accessible.
Reasons to straighten: reduce waste from excess motion, provide easy access to frequently used items, and open up space.
Straighten steps:
- Provide easy access to frequently used items.
- Group like items.
- Utilize visual designs.
- Use containers.
- Be agile.

SHINE

Elevate the work area by ensuring thoroughly cleaned and inspected tools, equipment, and other items.
Reasons to shine: engage and empower operators, give them more responsibility and agency over their work area, and identify problems before they interfere with production.
Shine steps:
- Clean the work area.
- Find the source of problems (e.g., leaks, spills, unexpected wear).
- Inspect each item after cleaning.

STANDARDIZE

Capture best practices for 5S as standardized work for the team.
Reasons to standardize: make 5S repeatable, transform 5S from a one-off project to a reproducible set of activities.
Standardize steps:
- Document in pairs.
- Establish procedures for 5S activities.
