EA Heuristic #2: Guess, Validate, Iterate: Time-bound architectural efforts

The spiral.  Architectural efforts should use this shape as the guide, doing quick iterations that each bring the effort closer to the end goal, but never getting held back from progress by attempts for perfection.

It is very difficult to document various aspects of an organization to the lowest level of detail or even to document the high level views correctly. To begin with, people have different views of the organization so the one correct viewpoint might not exist. As such, it is important to recognize that EA artifacts are living documents and they will never be 100% accurate. 

Consequently, time-bound architectural efforts to ensure consistent progress. Guess and validate later when there is missing information. Allow for iterations to gradually refine EA artifacts.

In our EA exercise, we planned a survey early in the exercise to solicit information on stakeholder importance. The organization rejected the survey, so we created the stakeholder importance chart based on our assessment. During subsequent presentations, the organization’s executives provided inputs that helped us refine the chart. Reflecting on the incident, it would have caused us unnecessary time and grief if we did not move on but instead wait on getting that chart right first.

  • When Will this Low-Innovation Internet Era End? – Justin Fox – Harvard Business Review

    Provocative view. Lots of good linked content.

    “It’s an age of unprecedented, staggering technological change. Business models are being transformed, lives are being upended, vast new horizons of possibility opened up. Or something like that. These are all pretty common assertions in modern business/tech journalism and management literature.

    Then there’s another view, which I heard from author Neal Stephenson in an MIT lecture hall last week. A hundred years from now, he said, we might look back on the late 20th and early 21st century and say, “It was an actively creative society. Then the Internet happened and everything got put on hold for a generation.””

  • Citigroup’s massive scalability challenges, by the numbers – Cloud Computing News

    Massive scale measured in business terms: trillions of $

    “$12.5 trillion. That’s the amount of customer money for which Benjamin’s half of Citi is responsible. About a quadrillion dollars worth of transactions flow through his system every year.”

  • The Creative Monopoly – NYTimes.com

    “[Thiel’s] lecture points to a provocative possibility: that the competitive spirit capitalism engenders can sometimes inhibit the creativity it requires.

    Think about the traits that creative people possess. Creative people don’t follow the crowds; they seek out the blank spots on the map. Creative people wander through faraway and forgotten traditions and then integrate marginal perspectives back to the mainstream. Instead of being fastest around the tracks everybody knows, creative people move adaptively through wildernesses nobody knows.”

    Now think about the competitive environment that confronts the most fortunate people today and how it undermines those mind-sets.

  • Beyond the 10,000 Hour Rule: Richard Hamming and the Messy Art of Becoming Great

    “”Great scientists tolerate ambiguity very well,” Hamming says. “They believe the theory enough to go ahead; [but] they doubt it enough to notice the errors and faults so they can step forward and create the new replacement theory.”

    This is perhaps the most important advice from among Hamming’s many suggestions. The path to excellence requires this balance between confidence and doubt, and though this balance is challenging, it’s tractable so long as your recognize what you’re facing.”

  • The Flight From Conversation – NYTimes.com

    “WE expect more from technology and less from one another and seem increasingly drawn to technologies that provide the illusion of companionship without the demands of relationship. Always-on/always-on-you devices provide three powerful fantasies: that we will always be heard; that we can put our attention wherever we want it to be; and that we never have to be alone. Indeed our new devices have turned being alone into a problem that can be solved.”

Social Collaboration vs. Quiet Contemplation

Roughly 20-30% of the population is acknowledged introverts and it’s no secret that IT has its fair share. One of the more famous is Steve Wozniak who dreamt up the first Apple computer in solitude. It’s highly unlikely that this quantum leap of imagination that changed the world would have bubbled to the surface in a boisterous brainstorming session. That’s because introverts like Wozniak excel in low-key environments and crave quiet to create, as Susan […]

End of "High Street Retail" As We Know It…..

More than 2,000 UK jobs were axed yesterday, as Game Group closed hundreds of shops after the company collapsed into administration. The beleaguered video games retailer, which had 610 UK stores, was unable to meet a £21m second-quarter rental payment due on Sunday and appointed the accountancy firm PwC as administrator. Is this the end of “High Street Retail” as we know it? Is it the beginning of the end? 

The writing was on the wall for Game for some time now. Earlier this month,the struggling video games retailer had confirmed that a number of its suppliers were refusing to do business with the company, sending its shares down 63% to 1.29p. Back then Game said that while it was trying to resolve the matter “as quickly as possible”, it was unsure if its efforts would be successful.

The Game is not the only retail business struggling for the past few years. Almost all high-street retailers have recorded reduced operating margins and profits, if at all they were there. The difficulties at Game are testament to the current squeeze on living costs coupled with a change in shopping habits and games technology. The group has also been battered by competition from cheaper rivals on the internet, such as Amazon and Play.com, and the major supermarkets. Separately, many people now download game Apps direct to tablets or smart phones, rather than buying software to be loaded in to consoles like the PlayStation, xBox on Nintendo Wii.

What the Game story tells us however is something unique where a Technology brand is being eaten by fast evolving technology business models. As Matthew Warman states in the Telegraph, “the story of Game is simply the first taste of what the web is doing to global retail – its products happen to be bought by users who migrated quickly to the web. All other specialist retailers are being challenged online: Whittards, to take just one example, is under pressure from specialist tea and coffee retailers such as Teahorse and Kopi, who will send subscribers superb selections every month, and cater to profitable, premium niches yet don’t have the overheads of high street rents and other associated costs. Many consumers simply see that they don’t have the inconvenience of shopping. Where Game led, even the most aromatic of products is set to surely follow.” 



It was not so long ago that another high-profile retail venture went bust in the UK. It was in November 2011 that, Carphone Warehouse announced that it was to close all of its 11 Best Buy stores across the UK. The first Best Buy store in the UK only opened in April of last year. But the outlets failed to make a profit. Carphone Warehouse and Best Buy initially planned to open 200 Best Buy stores across the UK and continental Europe. But clearly they had to abandon those plans well and truly before they could take-off. Is there market left for technology shopping on UK high-street? Probably there is and there will be always that small niche segment of shoppers who prefer to touch their electronic goods, CDs, Games and likes before they buy them. But that segment is shrinking all the time and internet players will certainly be calling the shots in this segment of Retail market.
