Study Notes

Lean Six Sigma Approach

Lean Six Sigma is a team-focused managerial approach that seeks to improve performance by eliminating resource waste and defects, as well as deviations from standards.
It involves 5 steps:
Define the problem, crafting a problem statement, goal statement, project charter, customer requirement, and process map.
Measure the current process, collecting data on current performance and issues.
Analyze the cause of issues, examining the process and data, displaying the data, investigating, and confirming what’s causing the issues.
Improve the process, deciding on solutions to fix issues and creating process maps for those new solutions.
Control, refining the new process, continuing to monitor, and using findings elsewhere in the business if possible.

5S Technique

5S is a systematic approach to organize and standardize the workplace, promoting efficiency, quality, and safety.
The 5S technique has 5 benefits:
Creating space within the facility by removing unnecessary tools and equipment.
Reducing downtime and improving quality by consistently maintaining equipment.
Reducing waste from unnecessary motion by organizing the workspace.
Engaging operators by granting them more responsibility for their work environment.
Creating a safer work environment by ensuring it is clean and well-maintained.

5S Steps

SORT

The SORT step separates items in the workspace that are needed from those that are not.
Items are categorized into:
Items needed in this work area, which are regularly used in the context of this work area.
Items needed in another work area, which are typically misplaced items.
Items you may need, which are marked with red tags, including the name of who tagged the item, why it is thought to no longer be needed, a proposed review date, and the name of the manager who must approve of disposal.
Items you do not need, which are immediately discarded, recycled, or donated, or sold if in good condition.

STRAIGHTEN (SET TO ORDER)

Not covered in the provided text.

SHINE

The SHINE step elevates the work area by ensuring thoroughly cleaned and inspected tools, equipment, and other items.
It involves:
Grabbing the metaphorical spray bottle, using appropriate cleaners and cleaning tools to make the work area sparkle.
Finding the source of any signs of leaks, spills, or unexpected debris, striving to understand the source.
Inspecting each item, examining its condition, and determining if it needs updating, maintenance, or repair.

STANDARDIZE

The STANDARDIZE step is a bridge between the first three 5S steps (SORT, STRAIGHTEN, SHINE) and the last step (SUSTAIN).
It involves documenting best practices for 5S as standardized work for the team, making 5S repeatable.
