    It depends on what point of view you are looking at it from(what institution/dept.):
    1. Statistics(Theory)
    2. Engineering (Application)
    3. Organisational Behaviour (Change Mgmt.)
    And also which country you are in, as this will determine what kind of data you get/ experiments you can do.

    Its a good topic for doctoral thesis, depends what facet of six sigma you wish to work on. One topic which comes to my mind is challenges faced by company integrating six sigma in Indian scenario, this is more of a managerial topic.

    Dear KP,
    One suggestion (truly on the ‘research’ side) could be to gauge whether there is any critical mass (size) of the organisation before SS can be effective. Your hypothesis could be to gauge the corelation of size of company versus the success (savings?) of SS.

    KP,
    If you read the threads on this site, you know that:
    1) many threads are about change management, the use of tools, or specific projects
    2) few if any threads are about “ground rules” to quantify and verify actual benefit in money or other key metrics – for example, I believe that productivity gains must be realized at the gross output level;  in other words, local gains that are consumed downstream should not be recognized.
    3) all posters, to their credit, are very passionate about Six Sigma
    4) few if any posters are executives
    What conclusions can you draw from my comments?
    Six Sigma commands attention in the United States, but I’m unaware of any publicly available studies that prove it works.  It does generate much of what we call “lip service” here, and American Executives, as a group, are extremely poor leaders.
    India may be a “clean slate”;  perhaps this is a way for you to create a model for Indian Six Sigma and objectively document its effectiveness.  If you look at my point #2, I can tell you that I have never seen any discussion, on the internet, a magazine or a book, of how a financial officer would evaluate a project before it is started.  Few if any American companies have Cost of Quality models.

    KP,
    First some background – I am an MTech from IIT, Madras with 20 yrs experience in Indian industry – 7 yrs at L&T, Powai, then a PSU Mishra Dhatu Nigam Ltd, then a Birla Co. Hyderbad Industries ltd etc. In Singapore with a division of ABB for the last 3 years, 2 yrs of which I have been  a BB. Admittedly, in SS I am a beginner.
    GE is doing  a lot of Six Sigma work in India. It may help to talk to some MBB there. In the university that you have registered in, keep in touch with a Prof. from the stats dept. and in the  organisation that you  work for /cement plant  talk to the QA people to get a hang of COPQ issues and problems with implementing Quality programs. If your boss and guide are not passionate about Six Sigma, you would find many things difficult.  My understanding of the high level of automation in a cement plant is that there may not be much room to play around with operating parameters to change quality or productivity. Considering the location of cement plants, the literacy levels and awareness of the employees need to kep in mind when looking at Change mgmt.
    The comments by DaveG and others are well taken.
    Most importantly, you may need to understand and clarify your motives for taking up a project in this area.
    Hope I am not adding to your confusion.

    Dear Raja,Daveg,John,Hemanth and others,
    Thanks for your all kind postings.I have noted. The background is that I have just taken admission in BITS, Pilani,in the I st semester, distance Ph D programme.and I have to submit the research proposal within 10-15 days.
    The normal black belt projects I see,are just about a B.Stat or M.Sc (stat).standards.I am looking for a real content which has certain researchable value.
    for one, I am thinking of ” Applications of Six Sigma integrating, Statistics, Operations Research and BPR methodologies in advanced Waste Elimination techniques.” here the intent is not committing the industry (cement,process manufacturing) not mentioning geography,like indian context, which enlarges your scope and  more time consuming in surveys and practical checking etc. like I already stated the combination is Engineering application and Quality management, which is general in nature can be applicable to all emphasising on Lean manufacturing.
    As of Raja’s comment, the applications of  Six Sigma  in cement, we have wide range of utility.Weight variation in 50 Kg bags , Process optimisation, Raw Mix design, introduction new products, productivity enhancement etc. I have recently applied CUSUM theory for validating energy savings form a vvfd ,and when the desired savings were not coming conducted DOE, for finding the erring factors.
    I would request you all to think on what  I proposed ,more so the applicability of BPR.wating for your responses,

    Hi KP
    Would like to know abt your program. What’s the duration of thesis?
    I still feel that something on formulating a roadmap for six sigma in Indian context would be good topic. The reason is, you would have a whole range of industry like service (software, BPO, etc) and manufacturing (both process and mass production) industry. Also, the challenges are in the areas like
    a. developing cost of poor quality models for specific industry type
    b. integrating six sigma with other initiatives like 5s, tpm, tqm etc.
    c. handling labor union related issues and other human aspects
    d. most important challenge is to integrate six sigma support structure within the organisation structure (esp a heiriarchical one)
    there could be other areas like the approach for a small scale industry vs a large corporation.
    this would need lot of time, if you have only few months with you then probably u can go in for an improvement project. Also, search the forum, as I remember there was a discussion on phd level projects some time back.

    I have a dream : having a chance to do doctoral thesis in Six Sigma.
    The topic in my mind is “Super Six Sigma”.
    I would develop the better Six Sigma methodology by blending current approaches (from various training institute) and some other methodologies such as Lean , Shainin ,Taguchi, TQM , ISO etc. and will use best of the best techniques form these.
    I would try my Super Six Sigma in some leading companies in my country and see the result.
    That is the thesis in my mind. However, it is just my dream.

    Dear 6 Sigma BB Coordinator,Yes. Precisely that should be the approach.To confide in you, Six Sigma, however wonderful it is, I find it has its own limitations.One, for example it can not really be applied to all kinds of  problems.Immeasurable things, it cannot take into consideration, however much u try to convert them into attribute data..If your problem is not fully defined in all aspects(totality), probably six sigma solution can be totally wrong and at the end of the day, u’ll wonder why desired improvements have not been obtained.We have that kind problems when we were attempting some quality related problems.
    I was reading the otherday that TPM has 426 problem solving tools.Now we may not be knowing a large majority of them, like wise  other methodologies also.It would be wonderful if some one attempts to combine all those so that six sigma in all its richness is applicable to all kinds of problems.

    Dear Hemanth,
    Thanks. I am scared of choosing such a large geographical boundaries.It would need considerable travel, time and may turn out to be damn expensive.Besides I am a working man and not a full time student.However I am noting down your suggestions.
    The otherday as I was taking stock of what subjects are available,which all contribute to the common end result,waste elimination, which is the need of the hour, I could write down about 24 subjects, which included Six Sigma also.one of the implied definitions of ss is waste elimination, or if you would like to put it in SS language reduce your defect rate, or avoid rework.and I am thinking why not make an attempt combine all other hi-tech subjects in making SS more stronger tool.
    The official time the university has given on their web is 2-3 years.Minimum 40 credits of work has to be done before being permitted to submit of the thesis.It depend how fast one can finish the minimum criterion.But there are people who took longer time.At least I dont have that kind of time.

    I think its a good area to do this thesis, but  the true impactdesired result  /  is to integrate and ensure that the new methology/standards may may be effecetivly used,..six sigma as we all know is a simple and user friendly way of achiveing desired results…..through a data driven approach, however looking at integration six sigma may be a means to acheive BPR in an organisation , but integration of BPR with six sigma with TQM and other standards together by being user friendly is a challenge in its own way…..i hope my views on the same do not confuse u…

    KP Rao,
    I infer that you are probably working in a cement manuf. co. and wish to do PhD at BITS. It is not clear whether you  are a HR person/Engineer. Also whether you have undegone Six Sigma training. Writing about Six Sigma without at least getting trained in GB/BB is like authoring a book on Love or Sex or meditation without having experienced any of them.
    Is your own organisation into Six Sigma? What ideas has your boss come up with? Is there any GE company in your town/city? What related topics have PhDs/MTechs been done in , at BITS? These would give you a good starting point. PhD (& probably life) is probably about asking the right questions than about getting all of them answered.
    Hope that confuses you enough to get your neurons firing. If not, I can suggest Tony Buzan’s “Mind Mapping” for a creative approach to problem solving.
    Good luck !

    Hi KP
    Well I do agree with you on time constraint. You might probably like to take up one of the areas which I mentioned that would scope your work a lot. I agree with one of the post previously posted here on developing a cost of quality model for a company that would be a very good thesis work.
    I am getting very much interested in the above program. could you send me some information on the program at my email id: @hotmail.com">hemanthsub@hotmail.com. I would love to know about this program and how did you find it. I hope this is not causing you inconvenience..

    How about you get a job and forget about the PhD.  If you are entering a doctoral program without any idea as to your area of interest of study then you don’t belong there.  Getting PhD recommendations from an online anonymous Forum is STUPID and LAZY and I would not allow you in any Doctoral program whether it be rigorous or not.

    I would not put it quite as “charmingly” as Darth does, but the matter of the fact is that this is absolutely the wrong place to get advice on a doctoral thesis. First off, there is a whole literature on Six Sigma and your dissertation needs to tie into this literature. The current agreed upon model for the investigation of any construct is: antecedents, determinants and consequences of Six Sigma. In most academic fields that touch upon Six Sigma it is viewed as a subset of TQM with a handful of British academics at the University of Lancaster for example attempting to find a niche for their research. Finally, every published empirical research of any quality will have a section on “implications and future research”. This is where you want to find academic sugesstions. No dissertation committee of any stature will accept a concept paper based on the suggestions of gooey, booey or villageidiot (no offense) from the isixsigma forum. Start with reading the literature, and take your first methodology classes. You may find that Six Sigma is probably one of the poorest topics to write a dissertation on.

    If you’re in PhD., it should be termed as dissertation and not thesis (for MBA only).
    My suggested topics:
    1. 1.5 sigma shift — worthy or inaccurate
    2. Accuracy and impact of results of a continuous and pseudo-continuous data as applied on stat tools for variable data
    3. Design for Six sigma and lean

    In academia, a thesis or dissertation is a document that presents the author’s research and findings and is submitted in support of candidature for a degree or professional qualification.
    The name for an academic thesis and the practice of its writing often vary across different countries and different academic degree obtained.
    Canada
    At English-speaking Canadian universities, writings presented in fulfillment of undergraduate coursework requirements are normally called papers, term papers or essays. A long paper presented for completion of an honours degree is sometimes called a major paper, or, more rarely, an undergraduate thesis or honours thesis. Major papers presented as the final project for a masters degree are normally called theses; and major papers presenting the student’s research towards a doctoral degree are called theses or dissertations.
    At Francophone Canadian universities, the procedure is roughly the same, however, the term applied to a study associated with masters work is referred to as a “mémoire,” and one associated with doctoral work is referred to as a “thèse.” Either work can be awarded a “mention d’honneur” (excellence) as a result of the decision by the examination committee, although these are rare.
    A typical undergraduate thesis might be forty pages. Masters theses are approximately one hundred pages. PhD theses are usually over two hundred pages, and may reach nearly five hundred pages in exceptional cases.
    UK
    At UK universities, the term thesis is usually associated with a Ph.D. (doctoral) or M.Phil. degree, while dissertation is the more common term for the research project required for an undergraduate degree, although it is not always a necessity, and degrees can be certified for completing other equivalent work.
    US
    In the majority of US doctoral programs, the term “dissertation” can refer to the major part of the student’s total time spent (along with 2-3 years of classes), and may take years of full-time work to complete. At some universities, dissertation is the term for the required submission for the doctorate and thesis refers only to the master’s degree requirement. At many others, the word thesis is used for both.
    Graduate students in many programs throughout the US are either required to write a thesis at the end of their studies or have opportunity to take a “thesis track” leading to graduation. Students who opt for the thesis route often are seeking to continue on for doctorates or are seeking employment where such an experience is valued.

    The 1.5 is not worth of a doctoral thesis. It’s history should be enough for anyone to see it is crap.
    Which 1.5 anyway ???

    Bill Smith’s uncontrolled 1.5 batch variation
    Harry’s 1.5 drift
    Harry’s 1.5 correction
    Reigle’s dynamic 1.5
    Add them up :
    1.5 + 1.5 + 1.5 +1.5 = six sigma !!!!!  Voila !!!!

    Peter,
    Thanks for a good laugh. I have just come out of a meeting where after a short moment of thought, the person that I talked to came to the conclusion: Ah, it’s 3 + 1.5 on each side. I think we now have a basis for a dissertation:
    Research Hypothesis: 6 = 1.5 + 1.5 + 1.5 + 1.5 (Peter’s theory)
    or
    Alternative Hypothesis: 6 = 1.5 + 3 + 1.5 (Layman’s theory)

    No – whether a company accepts the 1.5 sigma shift proposition or not has little bearing on a company’s success or failure.
    Giving a person the freedom to either accept it, or reject it, is an entirely different matter.

    I strongly disagree. Accepting the 1.5 and its associated six sigma tables will lead to a great deal of wasted time, wasted effort and misinformation about processes.

    *Minimizing  sd  from the  RM (rawmeal) to  the  finished cement product.
    * Improving  the homoginization of  the  intermediate  clinker  product.
    Furthermore   you  may  specify  the  following  task  forces:
    Operation,HR,Marketing,Reporting  & Information,and  Finance. 
    You  have  to  establish  teams  and   to  select  measurable  targets  for  each  TF,for  example the operation TF may  have  the  following  targets:
    *Achieve  a   certain  cost  per  ton   production

    May I in turn suggest that you are in no way qualified to recommend doctoral dissertation topics to anyone? 
     
    May I also point out to all current respondents to this thread that you’re tagging into a four year old posting?  
     
    Either the original twit has realized his or her own incapability of synthesizing and adding to the great Six Sigma body of knowledge or he or she should be well into his or her writing phase by this time.    
     
    You should perhaps continue to plow other more current fields – and remember (ye of many screen names), your plowing seems to go faster with your shallow tilt of the blade.

    ATI wasn’t responding to the doctoral post.  He was responding to a request for SS projects in a cement factory from 2 days ago.

    I think an absolutely fantastic topic would be “The Organizational Carrying Capacity of a Six Sigma Program Over Time.”
    There are loads of companies out there have found Six Sigma to be a beaucracy overtime – as is true of other continuous improvement methodologies.

    crb – your message is not clear to me. Appears you are knocking SS.
    If SS has failed at a company it is the fault of mngt in SS’s implementation. There can be nothing inherently wrong with using data to make decisions and following defined, repeatable steps to eliminate variation and non-value add costs.
    It’s cannot be bad in and of itself.
