A few weeks ago while analyzing the results of an internal test on a new web design we’re testing, it was brought up about how manufacturing is guided by Six Sigma standards. It was suggested the website live in a similar realm of excellence.
What is Six Sigma?
Six Sigma is a rigorous and disciplined methodology that uses data and statistical analysis to measure and improve a company’s operational performance by identifying and eliminating “defects” in manufacturing and service-related processes. Commonly defined as 3.4 defects per million opportunities, Six Sigma can be defined and understood at three distinct levels: metric, methodology (DMAIC/DFSSstructured problem solving roadmap and tools) and philosophy (Reduce variation in your business and take customer-focused, data driven decisions).
Can Six Sigma be applied to web development, design, and usability?
This is a very logical question. Yes, it can be applied, but achieving it is another issue altogether.
Pulling from Jakob Nielson’s November 2003 post, Six Sigma engineering relies on a five-step process called DMAIC (Define, Measure, Analyze, Improve, and Control). He was really ahead of his time in this article. A google search does not pull up much information on applying six sigma to web development, design, or usability. This tells me the concept has not been discussed too much and it makes sense — the web is still in its infancy, and the more experienced developers within organizations today are now moving into upper management where they are beginning to look at the website from a higher view within the company.
As the web becomes more of a vital tool for most businesses today, upper management (who often times knows little about how exactly a website goes together or how to build a successful site) is seeing the value in applying other business practices and methodologies towards the design, testing, and execution of their websites.
Why Six Sigma is difficult to achieve in web development today.
In manufacturing, the amount of variables encountered in an assembly line is not as vast as a complex website. Manufacturing doesn’t deal directly with consumers, either, and the manufacturing process has very strict processes and tolerances for how things are assembled.A website is dynamic in nature and also navigated and operated by your customers — customers who may not know a thing about your product and have had no training on your website. Manufacturing lines are staffed by duty-specific workers, trained to perform specific tasks accurately and efficiently.
A website on the other hand can be navigated in millions of different ways and combinations by millions of different people. Testing each of these combinations is impossible and will result in you testing your website into eternity without ever releasing it to the market. Add on top of this a team of people who are most likely very diverse in their backgrounds: developers, designers, and marketers — each come with their own education and experiences and often time have no visibility into what their other team members’ job responsibilities really entail (how many developers do you know that can truly do graphic design? how many designers do you know that can write complex database queries?).
Accept the variables in web development, and apply the concepts of Six Sigma
The key is applying the Six Sigma mentality to web development, design, and usability so you can get the best balance of accuracy and conversions. The problem most developers and designers have is that they get “tunnel vision” and focus exclusively on just one piece of the entire web application. This is a problem for any type of site which has multiple conversion funnels (sales, registration forms, contact forms, etc.).

- “Define” in the DMAIC process
More on this topic over the next several days as I cover each phase of the DMAIC process in individual blog posts in an effort to keep the posts spread out and on-topic, rather than one long, rambling post. 
I’ll provide links at the end of this post as each phase of DMAIC is evaluated.
