I need your help and advice since I tried two times to pass Six Sigma black belt but I failed
first time 93/150 , second 101/150
I read the BOK main book , I solved a lot of sampled questions but no used
from the analysis report I have weakness in the Team management and Analysis phases
Please advice for more resources ( simple explanations , tricks and sample exams ) so I can improve my self
The concepts and utilizations of "teams" varies around the world. The structure and leadership principles in your country and past work experiences may be significantly different then the current American concepts. In other certification preparations classes, i tell the participants to "discard" much of their work experiences and focus very specifically on the methods prompted by ASQ. All ASQ certification have some level of Teams BOK. Perhaps you can get your hands on the materials available via ASQ or Quality Council of Indiana for the CQIA and/or CMQ/OE and the most extensive discussion about teams.
Other members can advise you much more on the Analyze BOK than i am able to.
PRACTICE, PRACTICE, PRACTICE... especially formulas and calculator key sequences.
For the statistical problems, you should know when to use each of the tools. You should be able to know the following without looking it up and without hesitation. If you have a continuous y and a discrete x what tool do you use? If you have a continuous y and a continuous x what tool do you use? If you have a discrete x and a discrete y what tool do you use? If you have a continuous x and a discrete why what tool do you use?
You only have a few minutes per question so the exam will not ask you to work many problems completely from start to finish. However they may give you the partially solved equation and want you to fill in the remainder of the information from the given content.
Also I have found it useful to replicate problems that I have solved with statistical software manually in order to verify that I understand the calculations.
The best way to understand how this works is to actually do it in real life!
Good luck with your next attempt.
Back when I took my CQE I had to temporarily unlearn a lot of what we did at work to pass that test.
Best of luck on your next exam, you'll get there!
