A blog covering everything in the Architecture, Engineering, Construction and Real Estate industry - and plus a little bit more.

Dear Mom and Dad, Please Send Money!

"One of these days the industry will need to go back to the 1960’s (my experience basis) to learn profit is not a dirty word. Profit is needed to provide for the “cost” of mentoring and training craft, staff and management. This provides better employees.Better employees provide better productivity. Better productivity leads to better projects. Better projects lead to profits. This would seem to be a winning proposition for anyone involved in the construction industry – owners, architects, vendors and contractors alike."Don, I don't think companies today think profit is a dirty word, but it's more the investment of profits on human resources that makes them cringe.
We've Heard About Mentors, but Have Never Really Seen Them

In The Eyes of an Employer, Is it Better to be Single or Married?
There is always a very thin line between getting laid off due to lack of work and getting fired, similar to the thin line between genius and insanity I suppose. I know a ton of people at the moment who are laid off (including myself), but my question is: were they really laid off, or did they get fired?
So suppose this sharp witted business owner, manager, or executive is faced with a situation where they need to downsize their staff, perhaps it is because of lack of work, or perhaps it's because of lack of budget, or perhaps they just feel like getting rid of somebody. In any case, they are going to target the person or persons who make them the least amount of money. And I'm not talking about long term, sustainable profits, I'm talking about short term, money in front of their face now.Did You Get Laid Off, Or Did You Get Fired?

What Are Derivatives Anyway, And How Did They Screw Up Our Country?


So everything from the number of cups of coffee you drink each day to the variance of IQ scores will fall into some distribution of a bell curve. Itwould be safe to assume that quality items or as they are called, defects, will also follow this same distribution either in manufacturing or construction.
So what Six Sigma intends to do is take the number of defects in a particular process down to six standard deviations away from the mean (middle of the curve). Basically, this amounts to 3.4 defects per million opportunities (DPMO).
*Note: Six standard deviations from the mean would actually be about two hundred times less than 3.4 DPMO, but there is some theoretical shift of 1.5 sigma that occurs in the calculation that may or may not be legitimate and I don't really understand it. In either case, 3.4 or 0.015 DPMO is pretty damn good for a construction project so for all intents and purposes the difference is negligible.
So this is a nice little goal to set for yourself, but how might one go about reaching this pinnacle of quality? Six Sigma projects follow two project methodologies comprising five phases each with the acronyms DMAIC and DMADV.
DMAIC is used for projects aimed at improving an existing business process.
DMADV is used for projects aimed at creating new product or process design.
The DMAIC project methodology has five phases:
Define high-level project goals and the current process.
Measure key aspects of the current process and collect relevant data.
Analyze the data to verify cause-and-effect relationships. Improve or optimize the process based upon data analysis. Control to ensure that any deviations from target are corrected before they result in defects.
DMADV
Define design goals that are consistent with customer demands and the enterprise strategy.
Measure and identify CTQs (characteristics that are Critical To Quality), product capabilities, production process capability, and risks.
Analyze to develop and design alternatives, create a high-level design and evaluate design capability to select the best design.
Design details, optimize the design, and plan for design verification.
Verify the design, set up pilot runs, implement the production process and hand it over to the process owners.
My keen intuition tells me that construction projects will fall into the DMADV because every construction project is different. Which brings us to the main obstacle of implementing Six Sigma on a construction project: Construction is not manufacturing!
Six Sigma was developed by Motorola to improve quality. Companies like Motorola have the luxury of having design and manufacturing all in house and not to mention the fact that they are building the same thing over and over. Imagine trying to put an automobile together when it is not only a unique design, but every part of the car is installed by a different company! And then implement a quality management system for every unique installation that came down the line.
Construction isn't quite that difficult because you are working on a much bigger scale but we have to realize that implementing manufacturing principles into construction is just not that easy. Plus the whole Six Sigma black belt certification process is a little cheesy. However, a six sigma level of quality is nothing short of a fantastic accomplishment.
What is all this Six Sigma stuff and can it really be applied to construction?
