    I just completed my six sigma training. Can someone help me on what green belts do in the real world. Will I be leading a team, will I get additional training when I start working in this field. Please help I am nervous. It was a crushed program:-)

    What real-world green belts do:
    1. Work a full time job
    2. Spend about half of their time working six sigma projects directly related to improving performance of the company in the area that they work their full time job in. This requires them to go through formal training of some sort, likely out of the office for some period of time.
    3. Complete two six sigma projects that benefit the company and the processes that they work in, providing documented significant and tangible financial and performance benefits.

    The idea is that if someone does something properly, twice, that it will be engrained in their thinking. They will then continue to execute the tools of six sigma without having to formally start a project, but will know that they need to define, measure, analyze, improve and control every instance that requires improvement.

    Sorry, forgot to say:

    * In some cases you will lead a team. In other cases, you will be the team. It all depends on the project and your role at the company.

    * Make sure you have a strong black belt or master black belt overseeing your work. It’s their job to make sure you succeed. If you fail, it’s likely more of a comment on the overall structure of the six sigma program at your company than your competence.

    @Kay – This iSixSigma.com article might help (although it looks like John covered things pretty well in his post): https://www.isixsigma.com/new-to-six-sigma/roles-responsibilities/six-sigma-roles-and-responsibilities/

    @sigmadiva You need to understand there are no rules about any of this. If a company is smart in how they deploy they will modify the generally accepted practice to fit their culture. That is the smart thing to do.

    Generally a GB is a part time belt – some companies have full time GB’s. I am not sure what differentiates them from BB’s but that is what they are called. Most companies will tell their GB’s to dedicate 20-30% of their time to a project. That rarely happens unless of course the organization is very mature. A difficult part of a project is getting it through Define and Measure. We had a site where a GB launching a project would spend 2 weeks full time at the beginning of a project, co-located with the BB’s, completing Define and Measure. They would return to the part time role after 2 weeks. It worked for them.

    When we assign a GB to a project is is generally less involved than a BB project although it can be a more complex problem but the BB support should increase.

    For us BB’s work cross functionally and GB’s stay in the area in which they normally work (natural work teams). That sounds good but very few things happen in this world in a vaccum so you go where the project leads you. Generally you will get pulled out of your area to some degree.

    You need a coach/mentor. Hopefully it is someone who knows what they are doing. For new BB’s and new deployments we generally have close support 1BB to 4GB’s. As the program matures you see who is good at support and they get more GB’s and the ones that don’t do it well stay around 4 GB’s (they get more of the load for training or some other function and their MBB should be checking up on the level of support they are providing since they don’t do it well).

    Somewhere along the line someone seems to have made up a rule that belts need to be the team leader. If the organization has a working team program it would be dumb to alienate the team leaders by putting belts in charge. There is absolutely no reason a belt cannot join a team and function as a part of that team augmenting the skill sets on the team with some analysis capability.

    Regardless of structure your toughest job will be to execute change. Just a fact of life. You will see resistance to change. If the CEO doesn’t show up to kick everyone’s butt to help you with change don’t climb on that pathetic bandwagon that sits in the corner sucking on their bottom lip and telling everyone that top management isn’t bought in. It isn’t their job to make sure everyone blindly does what a belt tells them to do. If you get stonewalled get the BB involved – that is their job. You should have an escalation policy to help with this.

    An escalation policy is essentially something that says when you get stuck you have 48 hours to resolve it and then you escalate it to your BB. They have 48 hours to fix it then escalate it to the MBB, etc. As a GB you can easily get head to head with someone with more formal power than you and you will lose in that situation. Just part of the job. Move it up the ladder and let them resolve it. I will guarantee that it rarely goes more than 3-4 steps up the ladder. When someone is practicing passive aggressive behavior they generally do not like to have a spot light shine on them.

    Basically what you should expect is just about anything. Be flexible. Don’t worry about how it is structured just stay focused on your project and ask for help anytime you need it. Generally the biggest problems will come from within the SS structure. Someone who doesn’t like the way you analyzed something, a control freak, etc. The DMAIC methodology is a process that is designed to give you results. The tools are not cast in stone. Their are a lot of experienced belts that only understand this thing on the level that they execute tools – following footsteps on the floor they way they used to teach people to dance. Those are tool zombies. No original thought. They haven’t figured out what this is all about yet. Maybe never will. The focus should be on results.

    Just my opinion.

    @Sigmadiva

    I hope you have completed your Six sigma certification from an Institution rather than from an Organization (may or may not be you belong to).

    Interest for learning new things is very important rather than where you have completed your certification in general.

    In general, the interview questions regarding the Six sigma will be primarily to test the excellence of your curriculum learned or the project work you have carried out.

    A strong person on the fundamentals and as well as knowing recent updates in the curriculum are the key to succeed in any tough interviews.

    Best of Hardwork!!!

    @prabhuvspj You response appears to be a continuation of the completely disconnected incoherent ramblings that, when they do begin to approach reality seriously reflect your total lack of experience with anything remotely similar to CI in any form.

    Setting that aside please attempt to give me a straight and possibly coherent answer on this without going off into some psychobabble BS. What did you mean by:

    1. “I hope you have completed your Six sigma certification from an Institution rather than from an Organization (may or may not be you belong to).”

    2. “A strong person on the fundamentals and as well as knowing recent updates in the curriculum are the key to succeed in any tough interviews.”

    Anxiously waiting to see how well you can focus!

    @Mike-Carnell:

    Thank you for your serious comment.

    Since the owner of this post has has asked about what sort interview questions may be expected at the interview panel, I have mentioned like that.

    I am also anxiously waiting to see your reply!!!

    @prabhuvspj Nobody owns a question. People start strings and they go where they go.

    Lets assume your comment is true: “Since the owner of this post has has asked about what sort interview questions may be expected at the interview panel, I have mentioned like that.”

    I asked about 2 of your comments which you did not explain:

    1. “I hope you have completed your Six sigma certification from an Institution rather than from an Organization (may or may not be you belong to).”

    2. “A strong person on the fundamentals and as well as knowing recent updates in the curriculum are the key to succeed in any tough interviews.”

    Neither of these address questions that may be asked in an interview and actually the first question had nothing to do with interview questions.

    So your current response only answered one question – you could not focus. Rather than make every answer sound like you fell down some cosmic bunny hole just try to keep a grip on reality.

    Now – what did you mean by those two comments?

    Like, one of the best things about kicking back and, like, watching the world unfold in front of you and stuff. Is that sometimes you can start to recognize patterns. It’s like watching a really nice rug being made right in front of your eyes man.

    It’s like that one philosopher guy said…

    I forget what he said. Anyway, Prabhu seems to be a source to one of these patterns, especially if you ask him a question. I used the bold tag to help separate who’s who here, but the general disjointed responses make it more clear than…something that’s really clear.

    Dear Prabhu, how do you define quality?

    “Based on your reply, I would like to suggest the following:-
    Assumption: Quality related parameters are high important than quantity related parameters.”

    Dear Prabhu, I am having difficulty with a project. How can I get help?

    “Incase of any query, pls feel free to post and get it clarified by the suitable exe.

    Best of hardwork!!!”

    Dear Prabhu, do I need to do a Gage R&R before collecting data?

    “Yes. Gauge R&R is worth only. Since measurement system can be source for variation.”

    Dear Prabhu, how do I define my process capability?

    “As per your quote, you may be having some VOC on defects. Based on that you may calculate the process capability.”

    Dear Prabhu, should I consider a Six Sigma certification?

    “To add the above points on certified v/s non-certified, Certification is the process of recognition for the work.”

    Dear Prabhu, I have been tasked with improving call center quality. Where do I start?

    “According to my understanding, I hope you’re aiming to reduce the followup calls for an particular issue like if an query has been raised to the operator means the same need to be resolved during at that instance itself.”

    Dear Prabhu, what is the Pareto principle?

    “From my understanding the pareto principle 80:20 rule applied here can be misleading your study if the 20% of part is very huge (since it may be a hidden cost to the management).”

    Dear Prabhu, why do I need to learn statistics to do Six Sigma?

    “According to me, confidence interval related stuff can help better in the situation”

    Dear Prabhu, what do I need to calculate a confidence interval?

    “The formula the confidence interval is : P+/- Z alpha/2 * SQRT ((P *(1-P)/n)

    Where P is Population proportion

    n is sample size.

    From the above formula, it is clear that CI is function of Std deviation (Z alpha) and as well as the subgroup sample size.”

    Dear Prabhu, your indication of what Z alpha is doesn’t seem right. What are your qualifications?

    “Can you please elaborate your query in detail on LSS(Lean & Six sigma) perspective?”

    I mean that many of your answers are just poorly worded definitions of terms and don’t answer the question, and you don’t seem to really know much about statistics but still answer those questions as though you so. So why do you feel qualified to respond to every question?

    “Can you pls elaborate your query with what is the main objective and others…..”

    My mind is blown, man. I was almost beginning to think I had traveled back in time to when chat bots first hit the interwebz and you’d end up having the most convoluted conversations in your life. I’m not entirely unconvinced that hasn’t happened either. Woah.

    @prabhuvspj Accepting something as true is much different than assuming something is true. If you will go back to the original question it is about what GB’s “do in the real world.” The question regarding interview questions was one that Kay directed specifically at Katie Berry. Infact your comment wasn’t true but it seemed less important than your responses that you did not answer.

    Let’s get back to the two questions I asked you.

    1. Your explaination makes no sense with regard to you being hopeful that they were certified from an institution rather than a company. Why do you prefer an institution over a company?

    2. The second explaination I find relatively interesting. Regardless of who I interview they don’t get academic questions. I could care less about a bunch of esoteric crap. Understanding stats on some level is of course important but when you have software such as Minitab being able to write formulas from memory carries no weight. The software has the formula. I am much more interested in what the person has done and that is not specific to LSS. If an interviewer cannot ask anything beyond academic questions regarding training and this is the person an organization has made responsible to staff a LSS program then it is probably not going to be a deployment that has much success and therfore will have a short existence.

    Just to make my point on formulas try these:
    Standard deviation 3.1M hits in 0.2 seconds
    Standard error of the mean 3.39M hits in 0.31 seconds
    Mean 277M hits in .3 seconds
    Confidence Interval 2.9M 0.31 seconds
    If I get someone who actually thought memorizing these was important, I have the wrong person to staff my LSS program with. If I had someone that did these calculations by hand I would end the interview immediately. When you have software that does this you have Mistake Proofed the calculations. You can easily offset the cost of software 10X just in wasted time and calculation mistakes. I want people who think like that.

    Just my opinion.
