Check the Blue Bar to your left under Tools and Templates…or google either term….Wikipedia is always a decent place to begin for a general introduction to the idea or model you think might be helpful.

newbie replied to the topic Process Capability for transactional processes in the forum General 12 years, 7 months ago
If using MTB, it is a relatively simple matter of determining the distribution type (> Individual Distribution Identification…I think) and then calculating the Cp metric. Or you could transform it using a Box Cox or Johnson Transformation, again with a Cp follow-on. Or you could use DPMO or DPU, which doesnt require normality to be e…[Read more]

newbie replied to the topic KPI Throughput in the forum General 12 years, 7 months ago
I am just spitballing here, but it appears as if you would like to forecast future throughput for a given facility. If that is the case, then you would need to use a predictive model of some kind. You could explore the use of regression or monte carlo simulation, among others. Good luck.

newbie replied to the topic Lean Confusion…Still in the forum General 12 years, 7 months ago
Ok…that is making more sense. So you have lead time being a funcction of inventory and process velocity being a function of lead time with velocity measured as ‘moves per unit of time’. So reducing inventory reduces lead time and increase process velocity.
Then how is the added inventory of a supermarket pull system explained? As a c…[Read more] -
newbie replied to the topic Lean Confusion…Still in the forum General 12 years, 7 months ago
I was thinking about the idea of pull systems and of controlling inventory levels using supermarkets. In this case, arent you building additional inventories in the form of the supermarkets, with the result being you are able reduce the lead time it takes to fill a given order?
And if this is the case, then isnt that contrary to Little’s La…[Read more] -
newbie replied to the topic OR utilization in the forum Healthcare 12 years, 7 months ago
I doubt this question can be answered with any degree of accuracy without specific work study on a given OR and its operations. But if what you are looking for is some form of IE work study numbers, I imagine you could google that under time and motion studies + OR, etc.
Again, I would caution you in using such generic data. -
newbie replied to the topic Which test to use for non normal data in the forum General 12 years, 7 months ago
Running an analysis depends entirely on first determining what type of data you are working with. Your data set is naturally bounded by zero which is why your data set is skewed, which is what you would expect. If 90% of your data is zero, then it is pretty clear that 90% of something is working or not working, depending on if your 0s are ‘g…[Read more]

newbie replied to the topic Man hour reports in the forum General 12 years, 7 months ago
Use a lean approach to capture time elements. Using a VSM coupled with a work study breakdown or value-add assessment would allow you to break each process down into its individual work elements and value category, and then assign them time elements. You could also use a general Work Study to good effect. SMED techniques could also be ap…[Read more]

newbie replied to the topic Which Statistical tool for degree of performance in the forum General 12 years, 7 months ago
You might want to consider formal operational definitions coupled with a MSA of some kind, especially if you are not the only one assigning scores.
It might also be useful to take HornJM’s advice a step further and break out individual category scores in your worksheet, which might add to your analysis, as once you build the worksheet, the ‘…[Read more] -
newbie replied to the topic FMEA in the forum General 12 years, 7 months ago
You can use it wherever you need to assess and quantifiy the risks of something failing. It is often useful to combine the FMEA with another tool, such as a process map, that can then serve as the reference point for using the tool. But again, use it when you need to quantify risk as it pertains to a process, product, service, design, etc. Good luck.

newbie replied to the topic Beta in Hythesis Testing in the forum General 12 years, 7 months ago
You pick alpha, and Beta is calculated as a result of your other testing parameters (min difference, variability, alpha, test type, etc).
Knowing beta is only relevent to me as it pertains to power (ie Power = 1-beta). Knowing the Power of your test is critical, especially if you fail to reject the null (ie state there is no diff…[Read more] -
newbie replied to the topic Beta in Hythesis Testing in the forum General 12 years, 7 months ago
If using MTB and wanting to determine your Beta when running a one-way ANOVA, I suppose you could run a Power and Sample Size test retroactively to determine power, and then algebraically calcualte the Beta from there (power = 1-Beta).
There is probably an easier way, but that should work. -
newbie replied to the topic DOE for Patient Satisfaction in the forum Healthcare 12 years, 7 months ago
I think you are getting DOE and the subsequent analysis confused. If you are taking happenstance data in ordinal form (ie likert satisfaction scales) and then running it against various factor settings to determine the magnitude and direction of relationships of various factors on customer satisfaction, then I believe a better description of w…[Read more]

newbie replied to the topic Productivity metric – Police in the forum General 12 years, 7 months ago
Productivity is simply a ratio of what is generated from the process relative to its inputs. Increasing productivity then would require one to increase the output of the process while holding the inputs constant, hold the outputs constant while decreasing the inputs, or increasing the outputs while decreasing the inputs.
So what is your i…[Read more] -

You are lumping together a variety of different pursuits there…Basic project management would involve chartering up the idea, creating the work structure breakdown, and then managing to it.

newbie replied to the topic Final Inspection – Visual 100% ? in the forum General 12 years, 8 months ago
Dave T gave a good synopsis of the LSS opinion on this issue. I would simply add that practically speaking, I would want to control vendor quality, not methodology. Partnering with them in an effort to improve their processes is the ideal situation, but this is a long-term solution, and often difficult to implement….a practical, short-term co…[Read more]
