As part of a Dissertation work, I used the Kano Method to evaluate Customer Satisfaction. Below are excerpts from the dissertation. (Marketability of Solar Home Systems in the Rural Areas of Thumkur and Doddaballapur - Ranjit Arvindakshan & Deepak Sriram)
When one talks about Product features and Customer satisfaction, it is generally assumed that customer satisfaction is somehow directly proportional to how functional the product is – that is, the less functional the product, the less satisfied the customer is likely to be, and the more functional the product, the more satisfied the customer. This was a very one-dimensional way of looking at Customer Satisfaction.
The Kano model for understanding product features and their influence of Customer Satisfaction was created by Noriaki Kano, Professor at TokyoRikaUniversity in 1984. In his model, Kano, suggests a 3-dimensional model to relate product features with Customer Satisfaction. Since then the Kano method has been used by many a Marketing Strategist while considering product features and specifications. The power of the Kano model in Marketing lies in its requirement to collect the Voice of the Customer for product specifications. It classifies product features into Delighters, Linear Satisfiers, and Must Haves.
Fig: Kano diagram
The curved blue line running across the top two quadrants show Attractive requirements. Notice that as the number of Attractive requirements increase, the more satisfied the customer is likely to get. The curved red line running across the bottom two quadrants indicate the Must-have requirements. These features are a given and the absence of the features is likely to get the customer increasingly dissatisfied. The diagonal green line is the One-dimensional requirement, indicating satisfaction versus functionality.
It is to be noted that as the customers get used to the Delighters (Attractive Requirements, or differentiators), over time they become Must-have requirements as the customer begins to expect those features in all the models.
The Kano model requires that we ask specific questions that assess Customer Requirements against functional and dysfunctional features. The questionnaire is designed such that the questions have two parts: 1) How do you feel if a feature is present in the product? 2) How do you feel if that feature is not present in the product? The questions are rated on a 5-point scale:
1. I like it that way
2. It must be that way
3. I am neutral
4. I can live with it that way
5. I dislike it that way
The responses are then classified into one of six categories:
A: Attractive
M: Must-be
I: Indifferent
O: One-dimensional
Q: Questionable
R: Reverse
Category Q stands for questionable result. Normally, the answers do not fall into this category. Questionable scores signify that the question was phrased in-correctly, or that the person interviewed misunderstood the question or crossed out a wrong answer by mistake.
Category R, indicates that this product feature is not only not wanted by the customer but he even expects the reverse. For instance, when offering holiday tours it might well be that a specific customer segment wants pre-planned events every day, while another would dislike it.
I realised, from my efforts to prepare for the certification, that the network of Project Managers is all about collaboration and sharing. There are countless forums that share information on preparing for the PMP, or resources to help in the studies. In the spirit of that, I thought I'll share some of my lessons learnt from the exams before the news of it gets stale. :)
I underwent training in July (4 days, all weekends at Quahance) and registered for the exam during my second day of the training. I realised from my last adventure that taking the time to register for the exam puts you off track and therefore not ready for the exam.
Some of the highlights from the exam:
There were no negative-type or trick questions (questions with "not" in them eg. Which of these is NOT an example of Risk mitigation?)
I thought the Activity on Arrow was done away with the introduction of the 4th edition, but i got an AOA question that required me to compute the critical path. Not so tough, but would be good to be prepared.
Lots of questions on different types of EAC and earned value. The problems were not the straight forward "Calculate CV, given EV and AC" type, but a little more trickier. Good thing i was prepared.
Lots of questions on contract types, Risk.
It was easy in parts and tough in parts.
I thought there will be lots of wordy questions but I only got a couple like that and it did not bother me much.
Most questions were on Earned Value, Risk, Procurement, communication and conduct (not in any order)
Finished the exam in 2hrs and 10mins. This is with me taking the time to read and also go over a few questions that i had marked for review.
I did make changes to the original selection for the questions that i had marked for review
When the questions got tough, it got tougher and tougher before easing up again. Some of the choices on the tough questions seemed like all choices could be right (i'm guessing these were the sampling questions). The moderate and easy ones could easily be spotted with just one right choice.
I finished the exam with about 30 mins to spare. Could have spent some more time going through some of the answers i guess, but i had a full bladder by then.
Exam prep LL
I'm glad that i registered for the exam on the second day of the PMP prep training. The more you delay your application and registration process, the less likely you are to succeed in the exam itself.
I tried my best to get some of the guys from my training batch to get together for a joint study, but that never worked and i put in my efforts on my own. - Don't bank all your efforts on a group study. If the motivation levels are not the same across your group, be ready to hike it by yourself.
Always be in study mode. If you have a small study material that you got from the training institute, go over it daily irrespective of whether you have put in hours to study or not. This will ensure retention of key topics.
The podcast from Cornelius Fishner is really good. I heard a few samples from his site and wish i had invested some money in it. But i did not have the time for that.
My resources: PMBOK, Andy Crowe and Oliver Lehmann (both the 75 questions and the 125 questions: www.oliverlehmann.com), and no i did not read Rita. I used Rita's fastrack questions for one sample exam but gave it up after using Oliver's questions. Though the questions he has are a little tougher, what i really liked is instead of explaining the correct answer he would point to the source. A lot of the source happened to be books in the PMI library, so i must have read quite a bit about a lot of things that were in addition to what was in Andy Crowe or the PMBOK. Highly recommended!!
There were a few questions that still stumped me and I contacted Sameer, my trainer from Quahance, for the answers and he was kind enough to respond to me over the weekend despite that being his busiest time! Thanks, Sameer! Also helpful was his mnemonic of the processes which laid the foundation to retaining a lot of the knowledge in the PMBOK.
Also, if you can get your hands on the "Q&As for the PMBOK guide, Fourth Edition" from PMI; It will be very helpful. I saw a couple of questions today that were straight from the Q&As from the 3rd edition that was available to me in the PMI library. (Curiously the Q&As fourth edition is not available in the PMI library though it is out on print and also on amazon etc). Bottom line, PMI membership = value for money.
I did not memorize the ITTOs but i knew the process well enough, but i guess it might help to remember what Tools and Techniques are used in which process. There were a lot of questions on these - especially in Quality, Communication, Risk and Procurement.
In retrospect, i wish i had spent some more time studying. Would have breezed through the exam. But i suffered from the two classic symptoms of most projects: Parkinson's law and the student syndrome. Even in the last week before the exam, i lost 3 whole days due to some issues at home.
But what the heck, nothing beats seeing "Congratulations" on the screen soon after the end of test survey is done - I did not read what was on the screen beyond that. :)
On with the job hunt now. Good luck to you all!

This hilarious article was written by an Expert from Baan, Netherlands who spent two years in Hyderabad..
Driving in India For the benefit of every Tom, Dick and Harry visiting India and daring to drive on Indian roads, I am offering a few hints for survival. They are applicable toevery place in India except Bihar, where life outside a vehicle is onlymarginally safer
Indian road rules broadly operate within the domain of karma where youdo yourbest, and leave the results to your insurance company. The hints are asfollows:
Do we drive on the left or right of the road? The answer is "both".Basically you start on the left of the road, unless it is occupied. Inthat case, go to the right, unless that is also occupied. Then proceedby occupying the next available gap, as in chess. Just trust yourinstincts, ascertain the direction, and proceed. Adherence to road rulesleads to much misery and occasional fatality. Most drivers don't drive,but just aim their vehicles in the intended direction.Don't you getdiscouraged or underestimate yourself except for a belief inreincarnation, the other drivers are not in any better position.
Don't stop at pedestrian crossings just because some fool wants tocross the road. You may do so only if you enjoy being bumped in theback. Pedestrians have been strictly instructed to cross only whentraffic is moving slowly or has come to a dead stop because someminister is in town. Still some idiot may try to wade across, but then,let us not talk ill of the dead.
Blowing your horn is not a sign of protest as in some countries. We hornto express joy, resentment, frustration, romance and bare lust (twobrisk blasts), or, just mobilize a dozing cow in the middle of thebazaar. Keep informative books in the glove compartment. You may readthem during traffic jams, while awaiting the chief minister's motorcade,or waiting for the rainwaters to recede when overground traffic meetsunderground drainage.
Occasionally you might see what looks like a UFO with blinking coloredlights and weird sounds emanating from within. This is an illuminatedbus, full of happy pilgrims singing bhajans. These pilgrims go atbreakneck speed, seeking contact with the Almighty, often meeting withsuccess.
Auto Rickshaw (Baby Taxi): The result of a collision between a rickshawand an automobile, this three-wheeled vehicle works on an externalcombustion engine that runs on a mixture of kerosene oil and creosote.This triangular vehicle carries iron rods, gas cylinders or passengersthree times its weight and dimension, at an unspecified fare. Aftercareful geometric calculations, children are folded and packed intothese auto rickshaws until some children in the periphery are not incontact with the vehicle at all. Then their school bags are pushed intothe microscopic gaps all round so those minor collisions with othervehicles on the road cause no permanentdamage. Of course, the peripheral children are charged half the fare andalso learn Newton's laws of motion enroute to school. Auto-rickshawdrivers follow the road rules depicted in the film Ben Hur, and arelicensed to irritate.
Mopeds: The moped looks like an oil tin on wheels and makes noise likean electric shaver. It runs 30 miles on a teaspoon of petrol and travelsat break-bottom speed. As the sides of the road are too rough for aride, the moped drivers tend to drive in the middle of the road; theywould rather drive under heavier vehicles instead of around them and areoften "mopped" off the tarmac.
Leaning Tower of Passes: Most bus passengers are given free passes andduring rush hours, there is absolute mayhem. There are passengershanging off other passengers, who in turn hang off the railings and theoverloaded bus leans dangerously, defying laws of gravity but obeyinglaws of surface tension. As drivers get paid for overload (so manyRupees per kg of passenger), no questions are ever asked. Steer clear ofthese buses by a width of three passengers.
One-way Street: These boards are put up by traffic people to add jestin their otherwise drab lives. Don't stick to the literal meaning andproceed in one direction. In metaphysical terms,it means that you cannotproceed in two directions at once. So drive as you like, in reversethroughout, if you are the fussy type. Least I sound hypercritical, Imust add a positive point also. Rash and fast driving in residentialareas has been prevented by providing a "speed breaker"; two for eachhouse.This mound, incidentally, covers the water and drainage pipes for thatresidence and is left untarred for easy identification by thecorporation authorities, should they want to recover the pipe for year-end accounting.
Night driving on Indian roads can be an exhilarating experience (forthose with the mental makeup of Chenghis Khan). In a way, it is likeplaying Russian roulette, because you do not know who amongst thedrivers is loaded. What looks like premature dawn on the horizon turnsout to be a truck attempting a speed record. On encountering it, justpull partly into the field adjoining the road until the phenomenonpasses. Our roads do not have shoulders, but occasional boulders. Do notblink your lights expecting reciprocation. The only dim thing in thetruck is the driver, and with the peg of illicit arrack (alcohol) he hashad at the last stop, his total cerebral functions add up to little morethan a naught.
Truck drivers are the James Bonds of India, and are licensed to kill.Often you may encounter a single powerful beam of light about six feetabove the ground. This is not a super motorbike, but a truck approachingyou with a single light on, usually the left one. It could be the right one, but never get too close toinvestigate. You may prove your point posthumously. Of course, all thisoccurs at night,on the trunk roads. During the daytime, trucks are morevisible, except that the drivers will never show any Signal. (And youmust watch for the absent signals; they are the greater threat). Only,you will often observe that the cleaner who sits next to the driver,will project his hand and wave hysterically. This is definitely not tobe construed as a signal for a left turn. The waving is just anstatement of physical relief on a hot day.
If, after all this, you still want to drive in India, have your lessonsbetween 8 pm and 11 am-when the police have gone home and - The citizenis then free to enjoy the 'FREEDOM OF SPEED' enshrined in ourconstitution. Having said all this, isn't it true that the accident rateand related deaths are less in India compared to US or othercountries!!??
