Busin...Hi Jack,<BR/><BR/>Just in your reply, you hit on one. Business people understand the notion of "reducing risk" because risk is part of the equation that selects a company stock in the first place. By reducing risk, the value of the stock can go up, because it is less risky for the investors to earn dividends (or to gain the benefits of rising stock values).<BR/><BR/>So if you feel that "reducing risk" is one, that is cool. Do you think that, in companies that have adopted EA, that they can, over time, show that risk has been diminished?<BR/><BR/>Are there any other measures that you think would apply?<BR/><BR/>--- NickAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-29701096.post-41050452964016868732008-03-01T19:21:00.000+01:002008-03-01T19:21:00.000+01:00@NickWhat number, tied to the financial results of...@Nick<BR/><BR/><I>What number, tied to the financial results of the company, can you use to measure the results of the existence of EA?</I><BR/><BR/>However very important, I think the benefits of EA go beyond financial results or numbers tied to that. If it were about financial results that would mean that - hypothetical - companies with unlimited money would not need an EA. I don't believe that is true.<BR/><BR/>I think EA is more about staying into business at all. But I agree that it is difficult to find appealing measures to convince financial oriented folks. People who know that innovation is not an exotic anymore, but mainstream nowadays will be easer to be convinced of EA.<BR/><BR/>But I will give it a thought to find the Y for EA.<BR/><BR/>Thanks for your reaction, Nick.Jack van Hoofhttps://www.blogger.com/profile/10073941747649739657noreply@blogger.comtag:blogger.com,1999:blog-29701096.post-37309756160548049262008-03-01T18:28:00.000+01:002008-03-01T18:28:00.000+01:00First off, Jack, I want to say that I would relish...First off, Jack, I want to say that I would relish the idea of working with you someday. That's a rare statement for me, being a bit of a crusty dog myself, but you and I think alike. <BR/><BR/>So I agree that, the way in which we make the business better, is by smoothing out the changes.<BR/><BR/>Your diagrams are clear to me. Very nice. (I may adopt bits).<BR/><BR/>That said, the business doesn't ask for "smoothing out the changes" although they clearly need it. So I'd like to know what output we can point to in a business process that changes when EA is in the picture.<BR/><BR/>For example: the business that puts out an online service doesn't ask for software testers. What they want is for the loyalty of the customers to be high, because if loyalty is high, they can directly tie that result to financial gains. <BR/><BR/>So the business strategy is "Maintain High Loyalty". The Business Goals, therefore, include "insure a high quality, usable, secure, reliable product".<BR/><BR/>The business measurements, down below that, would include things like defect rates reduced, and service continuity tests, usability results, and security review results. Those are what six sigma geeks call the "little y's" (think y=f(x)... the little 'y' is the direct result of the formula. The big Y is the result of a formula that is so complex that it has not been modeled in math, but the business believes the conclusion to be 'true.')<BR/><BR/>So, that's the analogy. Now back to the question: what's the big Y. For testing, it is "Maintain High Customer Loyalty". For EA, what is it? What number, tied to the financial results of the company, can you use to measure the results of the existence of EA?<BR/><BR/>--- NickAnonymousnoreply@blogger.com
