Here's the view out the window (Ok, it's the window by the elevator, not the window in my room) -
Look at this office building. These workers can go out their office back door, and stroll along the walking path next to the San Francisco Bay. What a life...

So what's Six Sigma anyway? I'm glad you asked. In today's class, Jeff taught us that Six Sigma is a process improvement business strategy that began at Motorola. It has changed quite a bit since it was first used at Motorola.
If you really want to know what Six Sigma is, read what Wikipedia says...
"Sigma (the lower-case Greek letter σ) is used to represent the standard deviation (a measure of variation) of a statistical population. The term "six sigma process" comes from the notion that if one has six standard deviations between the mean of a process and the nearest specification limit, there will be practically no items that fail to meet the specifications.
Taking the 1.5 sigma shift into account, short-term sigma levels correspond to the following long-term DPMO (Defective Parts per Million Opportunities) values (one-sided):
One Sigma = 690,000 DPMO = 31% efficiency
Two Sigma = 308,000 DPMO = 69.2% efficiency
Three Sigma = 66,800 DPMO = 93.32% efficiency
Four Sigma = 6,210 DPMO = 99.379% efficiency
Five Sigma = 230 DPMO = 99.977% efficiency
Six Sigma = 3.4 DPMO = 99.9997% efficiency"
'What?' Yeah, that's what I said. Jeff didn't explain it that way (and I think you can see why). He actually did a great job teaching us how we can use Six Sigma at our businesses to improve our processes, be more efficient, save money, and make our customers more satisfied. Now that's what I'm talk'in about!
That's the original 45 year old door.
Here we go- first I tear the stucco off because I'm replacing the entire thing - the door AND the side-light.
The side-light window is out, and I'm ripping out the frame.
Now I'm ripping off the drywall on the inside.
Just one 2x4 left!
8:48 AM -
Demolition done! Time to prepare the 'rough' opening for the new door. But first...
9:45 AM - It's going to be a long day, so coffee and donuts are a well deserved mid-morning snack! Nick liked that part too!
Here's an important part - the 'sill'. That's right, a door has a 'sill' too (just like a window). I learned that from the guy at Home Depot. I got this one weather-proofed, perfectly sized and ready to go, then... the first set-back. I discovered that this 2x6 sill would be too tall -
OK, no use crying about it. I just need to find a hunk of wood that wasn't quite so thick and move along. Fortunately I had just such a piece of wood in my 'spare wood' supply.
All I had to do was rip the board to the right width, give it a couple of coats of weather-proofing stain, and I'd be ready for action!
Oh - look at the pretty flowers! Hey - there's a job to do! Quit
3:40 PM - The rough opening is finally ready! I had to add a 2x4 on one side and a 1x4 on the other, and of course the set-back on the door-sill cost me a lot of time. But finally, I'm putting the new door in place! That's Nick's arm sticking out from behind the door. He was too shy to actually show his face.
Time for shims! This is actually the trickiest part - getting the door straight, level, and not tweaked. I learned a lot about all of that on the side door a couple of months ago. That helped a lot, this part didn't take too long!
I was a little worried about the heat, since I was going to have a large gaping hole in the front of the house all day. Fortunately it didn't get that hot! And the house only got up to 80 inside.
5:00 PM - The first screw! Yeah - I'm starting to put screws in - that's a major milestone in my book!
6:12 PM - Been at it for almost 12 hours now. All the screws are in and the shims are cut off! It seems like I should be done by now, but wait... do I want to be able to lock the front door before I go to bed tonight? If so, I'd better put a door knob and deadbolt on. Next task...
I thought the door sill height was a set-back!? It turned out, the door hardware was fraught with issues. The door manufacturer did a poor job cutting the holes. The holes in the door didn't line up with the holes in the door jamb, and there were other problems. I had to do a lot of chiseling,
8:40 PM - YEAH! I'm snapping on the final piece to the doorknob hardware! I'm done! It's finished! I can't stand this door any more! I've been working on this thing for 14 hours now! Can't I go watch TV? No, I have to clean up - nuts!
Did you ever try Corona mixed with Limeade? I can attest - it's pretty good, especially after you've been working on your front door ALL DAY LONG!
