Monday, June 21st, 2010In earlier posts I wrote about “Define”, “Measure” and “Analyze” as part of Lean Six Sigma’s DMAIC cycle. The example I used in these previous posts showed that our office is not energy efficient, and we also analyzed where and why. Remember, the most important results of the Analysis phase are well determined problem causes. […]
You Can’t Control What You Can’t Measure
Friday, May 14th, 2010I am still concerned about what’s going on with the oil spill in the Gulf of Mexico. Previous estimates were that 800,000l oil spill into the sea every day. Some scientists come to the conclusion that it is more likely to be 10 times more! It seems to be consensus that right now nobody knows […]
Lean Means Sustainability – Step 3 – Analyze
Tuesday, March 23rd, 2010In earlier posts I wrote about “Define” and “Measure” as part of Six Sigma’s DMAIC cycle. Step 3 is “Analyze”, the “A” in DMAIC. The intend of this step is to understand what causes the problem defined in step 1 – “Define”. Let’s assume we characterized our problem that we spend too much energy in […]
Lean Means Sustainability – Step 2 – Measure
Wednesday, March 3rd, 2010Earlier I wrote how to start a lean sustainability initiative by defining objectives and framework. Step 2 of the DMAIC cycle is “Measure”. It sounds obvious that we need to know where we are before we know in which direction we need to go. By measuring we are trying to understand where we are, and […]
12 Principles Of Green Engineering
Thursday, February 18th, 2010In 2003 scientists proposed ideas for green engineering. Based on work done to articulate principles for green chemistry, Anastas and Zimmermann developed principles for “Green Engineering”. I do like the pragmatic approach inherent in these principles. I think it is worth to look at these principles: 12 Priciples For Green Engineering: Inherent Rather Than Circumstantial […]
