Lean Manufacturing

Trash Can problem- Motion+ Transport waste

Scenario: Placing a Trash Can Near Your Desk

• What Bugs Me: Having to get up, walk to the kitchen, and throw away water bottles interrupts my workflow and wastes time.

• Waste Identified:

• Motion: Unnecessary movement caused by the trash can being far from your workspace.

• Waiting: Minor delays caused by stopping tasks to dispose of trash elsewhere.

Solution Implemented

• Action Taken: I placed a small trash can next to my desk, eliminating the need to walk to the kitchen every time I needed to throw something away.

Results

• Efficiency Gains:

• Saved time and energy by cutting out unnecessary trips.

• Reduced interruptions to focus and productivity.

• Lean Principle: By addressing excessive motion (one of the 7 Lean Wastes), this small change streamlined the workspace and made it more functional.

Defects

When building a part in CAD, i have to meet certain requirements and specs. When i build a part off of a wrong specification, i would have to restart the part, which is wasted time. After that, i always was super careful with my CAD work to lessen the amount of errors.

Inventory and Motion waste

I tend to leave alot of clutter and random items at my desk. This is due to me needing to use them one time, then just putting it on my desk and forgetting about it. I recognized this, then cleaned, and organized my table, leaving only what i need for the day. Ex. water, batteries if my controller goes out, and a charger. For the 3S's i cleaned my table, for sweep, sorted all of the items for Sort, and made a place for miscellaneous items that are not needed at my desk elsewhere.

Waiting

When i get completed with a job early, i usually find myself scrolling on social media and waiting for my next job. Now, with my free time, i always design in CAD if im just sitting there waiting for a job to minimize wasted time and potential

Over Production

When cooking, sometimes my eyes get hungrier than my stomach and i end up cooking more than i need. When i realized this, with the help of the diet i was on, i noticed that i dont need too much food to feel full and energized for the day. To fix this over-production problem, i decided to cook way less to minimize food waste.

Over-Processing

When i made my CNC 3 Axis Mill challenge, towards the end i wanted to add another facing pass after i already faced the part in the beginning, this was a prime example of over-processing because no matter what, if you faced it already in the beginning, facing it at the top at the end wont really do much to the finish, it will most likely still be the same. One thing for sure is that it wont add any value to your part, so its a complete waste. To fix this, i removed the facing at the end, kept the initial face at the beginning, and the part came out perfectly.

2 second improvement- Motion Waste

When 3D modeling with specifications, i myself always having to look at the requirement sheet of the part, what i can do is write it down on a note pad on my computer, and it put on my other monitor, so all i have to do is look to the right and not having to look around for the paper.

Plan to clean my desk | Inventory waste

For my 2 second fix is to organize the mess in my working area

How:

Preparation:
- I decide on a temporary space, like the ground or another desk, where I’ll place the items from my desk.
- I gather my cleaning supplies, such as wipes and a cloth, and keep them within reach.
Clearing the Desk:
- I begin by picking up each item on my desk one by one.
- I carefully place the items onto the temporary space I’ve designated.
- I check drawers or under the desk for any stray items and include them in the clearing process.
Cleaning the Desk Surface:
- I take a cleaning wipe and thoroughly wipe down the entire surface of the desk.
- I make sure to clean areas that tend to collect dust, crumbs, or smudges.
- Using the cloth, I dry and buff the surface to remove any residue.
Assessing and Organizing:
- I review the items I’ve moved off the desk to decide what I truly need to keep on the desk.
- I group the items into categories, such as office supplies, personal items, or decorations.
Returning Essentials to the Desk:
- I place only the items I need for daily use back onto the desk in a logical and organized way, this includes my calendars, my meds, and wet wipes in case i spill food on the table or to clean my monitors
Storing Non-Essentials:
- I identify items that don’t belong on the desk and decide where they should go.
- For example, I take my masks that i just threw on my desk after a camping trip and put it where it belonged, in my wardrobe
- I return each non-essential item to its appropriate spot.
Final Touches:
- I step back and take a moment to assess the newly organized desk.
- I make small adjustments to the placement of items to ensure everything is both functional and visually pleasing.
- I throw away any trash or clutter that I’ve accumulated during the process.
Maintenance Plan:
- I make a mental note or set a reminder to repeat this process regularly to keep my desk clean and organized.

9. Visual cue:
I wrote down a list and hung it by my table that reminds me to make sure my desk is clutter free every time i take a seat.

This ensures I maintain a workspace that’s both tidy and efficient.
