Matrix for choosing the best suited business tablet/laptops

After we learned the QFD method in product excellence with using Six Sigma module, I was considering about how I can use it in my individual life. Actually, I have been dealing hard times deciding to buy a new tablet/laptop/ultrabook (whatever it is), after I met the awesome product which is Microsoft Surface Pro 2!! By the way, I was using my current one more than 6 years. However, in order to choose the best one, I checked other brand's collection like “Asus-Taichi” as well.

After I watched hundreds of reviews on YouTube, I eliminate other opportunities and focus on Microsoft Surface pro 2 and MacBook air. Then, I made a matrix on Excel. Although I wanted to do QFD, it doesn’t make sense to me due to irrelevancy between choosing a notebook and complex design tool (QFD). However, I have influenced from Paul's speech on class, and prepared a matrix.

Steps of Matrix:

1) Wrote down my criteria such as CPU performance

2) Determined the significance levels of each criteria according to me

3) Compared the two products with respect to criteria

4) Calculate the overall score

My expected criteria from business product are "price, CPU performance, Video Card Performance, RAM, Touch Screen, Ease of design with Pen, Portability, Estimated Durability, Battery life, Resolution."

And here is the matrix:


Consequently, the overall scores are almost same; however Surcafe Pro 2 get higher score than MacBook Air.

Guys please write your own feedbacks and experiences about this topic, I need it. Thanks!

    Hey Nihat,

    I really like your post. It’s pretty interesting when you try applying these principles with real life decision making on subjects that may not be related to manufacturing.

    For your excel sheet, it’s great you reached a conclusion that the surface pro 2 is your choice, but i think you might need to exclude MacBook Air from the equation at the very start. The reason i say this is because the criterias you choose from these two points (as seen in your excel) MacBook Air looses 10 full points because of the touch-screen feature. So I would suggest needing to choose to begin with – are you looking for a touchscreen featured device or not. Because if that was not part of the calculations, the MacBook Air would win easily.

    Either way, i think the point of QFD is this type of discussion, which is great. We can do a full qfd on this decision making of your next device actually.
