Dr. Eugene Jacquescoley

Niall,
Which forum did you initially plan to post your message? Secondly, if your analysis is referring to Applied Statisitics, observational errror (OE) is the difference between a measured value of quantity and its true value. With this being said, refer to the probability theory before tackling the t-test. The probability theory will provide…[Read more]

Mark,
Just out of curiosity: How did you define “wait time” in your project charter?
E

This is an intriguing question and possibly, an interesting  assumption. Standard and Poor’s provides services in credit ratings, indices, equity research, risk solutions, funds and data servcies. So it seems formidable for one to consider this organization as the premier benchmark (in terms of quantitative and qualitative success, while examing t…[Read more]

Phillip,
Congratulations on your new Black Belt certification, as well as your new BB position. Building a roadmap for a new  process is not easy and you appear to be on the right track. I suggest you combine DFSS with DMADV.
(Simon, 2006)

DMADV
Define Measure  Analyze   Design    Verify

Andrew,Lean does appear to be the appropriate methodology to utilize in this particular matter. But I would suggest complenting this methodology with DMAIC, to get better handle on the root cause analysis of your processes. Nursing shortage issues are quite complex and depending how sophesticated the architecture of your current SixSigma…[Read more]

Thanks Darren. E

BB,As a Black Belt, you have several options, especially in healthcare at the moment. For example, the CDC, FDA and DHHS are looking for individuals with your background in various disciplines. In the civilian sector, you may be correct, in terms of SS reaching the saturation point (Depending on who you ask and what forecasting methods were…[Read more]

[email protected] look forward to your email.Many thanks.

John,What scheduling platform (e.g., IDX, Medical Manager) is your department/organization currently using? E

Liz,Considering nurse full-time equivalents (FTE) a data consideration is crucial in your analysis. But before I can entertain your question, have you considered the following:Have you categorized the surgeries/procedures?
How have you categorized this data?
Have you considered the physician FTE in your analysis? If not why?
When examining…[Read more]

D,You’re out of control. Have a good weekend.
E

D,That isn’t a very nice reply and I wasn’t aware that I had two seperate screen names. Nonetheless, I stand by my responses to John & Woo.Kind regards,
E

Woo,It appears that a Histogram would serve your purpose compared to the Box-Cox. The presumption of utilizing the Box-Cox Transformation is that the data needs to be normally distributed. Based on a glimpse of your data, it appears that you do not have this problem.E

Ritz,Your response is somewhat correct. However, the distinction is what type of t-test John plans to utilize with measuring the responses from the Likert Scale. As I mentioned before, X & Y metrics can be continous and discrete…and of course caution must be used when inference or generalizing results to the public. This is why we have Welch’s…[Read more]

Darth et al,Thanks for responding and your questions are valid. X & Y metrics can each be continous or discrete. A continous measure will have reading on continous scale where a mid point has meaning. A discrete measure, as you’re aware is categorical in nature. This is why I suggested the use of a Likert Scale to collect responses from John…[Read more]

Amisha,Depending on your industry, will depend on you waiting for the perfect BB opportunity to present itself. Considering that you’re already a Green, there are opportunities for individuals with this certification. I would encourage you to continue seeking employment as a Green or Mid-level PM, while pursuing your BB certification with…[Read more]

Ok.

A.J.,As you may be aware, Root Cause Analysis (RCA) or what some of us like coin “Systems Thinking” is required when an unwanted situation which consumes resources and tends to happen in a repeated fashion then there is a possibility that it might be beneficial to figure out what is really causing this situation to occur and remove it so the…[Read more]

Mario,Sigma XL 4.21 has the capability to address this issue for you. > you have done your data manipulation, I suggest that a Cause & Effect Matrix. Which may be helpful in your average defect analysis.. If you utilize this fx., make sure you perform a Run Chart.
Run Charts allow you to see trends and outliers in the data. It is the precursor…[Read more]

AJ,What is your ultimate goal of pursuing RCA?E
