Occam’s Razor and Enterprise Architecture

“Occam's razor (sometimes spelled Ockham's razor) is a principle attributed to the 14th-century English logician and Franciscan friar William of Ockham…The principle is often expressed in Latin as the lex parsimoniae (‘law of parsimony’ or ‘law of succinctness’)..This is often paraphrased as ‘All other things being equal, the simplest solution is the best.’… it is more often taken today as a heuristic maxim (rule of thumb) that advises economy, parsimony, or simplicity.’” (Wikipedia)

In Occam’s razor, “razor refers to the act of shaving away unnecessary assumptions to get to the simplest explanation.”

Thomas Aquinas made a similar argument in the 13th century: "If a thing can be done adequately by means of one, it is superfluous to do it by means of several; for we observe that nature does not employ two instruments where one suffices." (Pegis, A. C., translator (1945). Basic Writings of St. Thomas Aquinas. New York: Random House, 129.)

The principle of Occam’s razor is very applicable to enterprise architecture—how?

Occams razor is a call for simplicity, and this principle is a foundation for enterprise architecture in terms of consolidation, integration, and cost efficiency and takes specific form in terms of:

  • Systems interoperability and component re-use
  • Technology standardization and simplification

Paul O’Neill, the former Secretary of the Treasury was a true advocate of Occams razor and frequently asked “if not one, why not one?”

“The philosopher of science Elliott Sober once argued along the same lines as Popper, tying simplicity with ‘informativeness’: The simplest theory is the more informative one, in the sense that less information is required in order to answer one's questions.” (Wikipedia)

In this sense, Occam’s razor is a validation for User-centric Enterprise Architecture, which seeks to make information simpler, easier to understand, and generally more valuable and actionable to the end-user to enhance decision making. Moreover, Occam’s razor is also evident in User-centric EA application of principles of communication and design like simplifying complex information and maximizing use of information visualization in order to more effectively communication EA information.

Occams razor makes clear the need to transform from traditional EA’s development of “artifacts” that are often difficult for the user to understand and apply and instead develop more useful and usable information products and governance services.

Design and Enterprise Architecture

Design, style, and innovation are important communication mechanisms and are crucial to User-centric EA. These communication mechanisms are used in information visualization and is heavily used in EA to develop useful and usable information products that can be easily understood and applied.

Increasingly, design is taking center-stage across technical and everyday products in our economy.

The Wall Street Journal, 4 January 2008, reports in no less than three separate articles on the importance of design and style for everyday products from computers to hard drives and even storage containers.

Here are some examples from a front page article titled, “PCs Take a Stylish Turn in Bid to Rival Apple”:

  • “Dell is trying to inject a sense of style into the company’s PCs, with new shapes, sizes, and color.”
  • PC Makers are “racing to replace boring boxes with sexy silhouettes that will differentiate their products, entice new buyers, and command higher prices.”
  • Forrester Research “issued a report last June heralding a new ‘age of style’ in the PC market. It concluded that more attractive models could command $150 to $200 more.”
  • “During most of the industry’s 30-year history, PC makers didn’t worry much about style. A bigger challenge was boosting technical performance and wringing costs from suppliers.” Now an Intel anthropologist states “there is a sense of, ‘Oh my G-d, why does this have to be so ugly?’”
  • Lenovo stated that now “designers have equal weight at the table.”
  • Dell has gone from 6 designers in 2001 to 90 designers now and they are still recruiting.
  • At the upcoming Consumer Electronics Show, Microsoft will hold a PC ‘fashion show’ with judges picking the top three designs.

Additional articles the same day point to the importance of design and style. For example, the article “Can a Hard Drive Make a Fashion Statement” states that Seagate “kicked off a new strategy at the 2007 Consumer Electronics Show, offering drives with sleek shapes and lights to woo users accustomed to iPod-like elegance.” And in another article titled, “The Struggle to Contain Ourselves,” about the briskly growing $6 billion storage and organization industry where “style is increasingly important” and “once just plastic bins in industrial blue or clear, specialized storage products are now available for most conceivable uses in an array of material, from bamboo to faux leather to sea grass.”

While certainly consumer products are different than information products provided by EA, there is clear understanding now that design, fashion, style, and innovation are critical in reaching out to people, getting them interested in your products (consumer or information), and that design demands a premium in the marketplace. As the Intel anthropologist stated “why does this have to be so ugly?” Similarly, I would ask why do traditional EA products have to so often be so ugly, difficult to understand and apply. Let’s transition the way we do architecture to User-centric EA and design innovative information products that capture our users’ attention, really “talk to them,” clearly identify problem areas, propose alternative solutions, and lead to better decision making. Our executives are busy people with challenging jobs. We owe it to them to provide information in User-centric EA ways.

Systems Monitoring and Enterprise Architecture

When we log on at work, most if not of us get some sort of message that logging on connotes acknowledgment to monitoring and that there is no implied privacy to what you’re doing when logged onto corporate IT assets.

Monitoring is a way of life at work. It is part of information security, management oversight, and ensuring systems are running effectively (and preventing a severe network outage).

Kenneth Klapproth in DM Review, 22 February 2008 reports that network management tools are able to collect date “across the shared network to present real-time and historical availability, performance, and configuration statistics on individual services and applications.”

Cross platform monitoring and event management and resolution are important to maintaining the availability of today’s complex networks that are vital for corporate communications (voice, data, and video).

  • ALERTS: Monitoring not only alerts IT personnel to when networks falter, but can also be set to provide alerts when certain fault tolerances are reached, so that IT personnel can take action before the network is brought down.
  • CAPACITY: Network monitoring identifies not only when the network becomes overloaded, but also when there is excess capability that can be more optimally used.
  • TRENDING: Performance is not monitored as snapshots in time, but also can provide historical trending that can provide valuable information based on usage patterns.
  • VISUAL REPORTING: “Dashboard and web displays deliver visually compelling and graphically concise reports [of key network and capacity utilization trends] that enable organizations to make the right decisions faster and with more confidence.”
  • QUALITY OF SERVICE: QoS is improved with monitoring. “Managers can see the current and historical use and performance of network resources, monitor and report on congestion, correlate QoS configuration with network performance, and use the information to improve traffic and service delivery.”

Additionally, many network monitoring tools have the ability for other key management features including self-discovery and healing. These features include: IT asset management, remote control, problem resolution, operating system set-up and configuration, software distribution, license monitoring, back-up and recovery, security, and lights-out management.

While network monitoring and management are more operationally focused, they are critical from an enterprise architecture perspective to ensure the delivery of core IT functionality for the enterprise: namely, a robust, sound, secure, cost-effective, state-of-the-art IT infrastructure upon which information can be delivered to the right people, anytime, anywhere.

Network management tools can also be helpful in building the enterprise architecture because of their asset discovery feature. With the ability to spider out over the network and touch anything with an IP address, these tools can help identify key enterprise architecture assets in order to establish the baseline and plan for future targets.

User-Centric EA Framework


 
User-centric EA guides all facets of the enterprise architecture. It starts from the capture of the information, which is based on a strict value proposition of improving IT planning and governance, and moves forward to a process that is collaborative and structured, to one that provides users with information views that are facilitated by principles of communication and design. The User-centric EA further affects how we manage the architecture, using metrics, configuration management, and a single information repository. It also affects how we enforce the architecture through policy and governance.

IT Project Engineering and Enterprise Architecture

Architecture and Governance Magazine, Volume 4, Issue 1, has an article called “The Secrets of IT Success: Transforming Companies” that identifies three critical architectural elements necessary for successful IT project execution, or as I see it, project initiation.

These critical IT project elements are as follows:

  • Community Analysis—“It must understand the needs of the customers, the supply chain, and the transactions necessary for the day-to-day running of the business…generate understanding on both the business and IT sides of the equation, to capture organizational goals comprehensively, and to enable effective training and buy-in, IT analysts and engineers must identify with and embrace the community to be transformed.”
  • Operations Analysis—“A deep understanding of the operational activities, capabilities, and business processes…Here work activities are identified, captured, and catalogued so that information flows, technologies, roles, and other processes and elements can be accurately mapped. The analytical results from this phase give a clear perspective to move from the business’s needs to the requirements of the new technology that will need to be implemented.
  • Technology Analysis—“technical needs are defined and blueprinted, and their intersections with business rules are specified…A multidimensional analytical view encompassing user workflow, technologies, data, security, business rules, and interfaces can greatly enhance the pure IT view of transformation.”

To me this translates in simple terms to the following:

  • Business needs
  • Functional and technical requirements
  • Technology solutions

While these IT project elements factor into the development of the enterprise architecture, they are more the domain of segment and solutions architecture that work toward business and operational outcomes, rather than strategic-level outcomes.

The article also calls for the use of visual tools to aid in IT project analysis:

  • In all three phases, a key ingredient is supplying a visual tool as part of the universal language that will be used throughout the project to facilitate clear communications between members of the community affected by it. Consistent and unambiguous visual expressions of the operational need and intent immeasurably enhance the likelihood of a successful IT implementation.”

This call for the use of visual tools is similar to and supportive of the use of information visualization in User-centric EA, where information visualization is especially helpful in the high-level, strategic profile views of the architecture as well as in modeling business, data, and systems. In all areas of User-centric EA, the principles of communication and design are critical for developing useful and usable information products and governance services for the end-user.

Craigslist and Enterprise Architecture

Craigslist is a centralized network of online communities, featuring free classified advertisements (with jobs, internships, housing, personals, for sale/barter/wanted, services, community, gigs, resume, and pets categories) and forums on various topics.”

Here’s some basic stats on Craigslist:
  • Founded in 1995 by Craig Newmark for the San Francisco Bay Area.
  • Incorporated as a private for-profit company in 1999.
  • Operates in approximately 450 cities in 50 countries.
  • Operates with a staff of 24 people.
  • Estimated annual revenue as high as $150 million in 2007.
  • Sole source of revenue is paid job ads in [11] select cities [and apartment listing in NYC].
  • Over nine billion page views per month, putting it in 56th place overall among web sites worldwide, ninth place overall among web sites in the United States, to over thirty million unique visitors.
  • Over thirty million new classified advertisements each month, Craigslist is the leading classifieds service in any medium. The site receives over two million new job listings each month, making it one of the top job boards in the world. (Adapted from Wikipedia)
Craig has taken basic website technology and revolutionized the business of classified advertising, and for the most part making it free of charge!

Why is Craigslist such a success?

I believe it is because of Craig Newmark’s almost complete adherence to user-centric enterprise architecture principles.

Here are some examples of this:
  • User Focus-- “In December 2006…Craigslist CEO Jim Buckmaster told Wall Street analysts that Craigslist has little interest in maximizing profit, instead preferring to help users find cars, apartments, jobs, and dates.” (Wikipedia)
  • Customer-driven—“People suggest stuff to us, we do what makes sense, and then we ask for more feedback,” says Craig Newmark.
  • Customer-service—Craig Newmark’s official title is founder and customer service representative. When asked where Craig sees Craiglist in five years, he states: We always need to improve customer service. For example, we need better tools to detect and remove spam listings.”
  • Rejected annoying banner ads—“At the end of 1997, [we] hit a million page views a month. Then the folks at Microsoft Sidewalk wanted to run banner ads on the side, and at market rates, that would be all the money I needed to live. [But] I figured…I don’t need the money, and many banner ads are pretty dumb.”
  • Technology-enabled—“We’re just starting. We have to improve technologies, like multicity search.”
  • Culture of service—“We think we have a really good culture of trust and that’s because…we have stood by some core shared values. The fundamental value is that we feel you should treat people like you want to be treated.”

The only non-user-centric EA aspect of Craigslist is the quirky look and feel of the site, which is white, mostly text-based. As Craig acknowledged, “someone said our site has the visual appeal of a pipe wrench.”

(Adapted from ComputerWorld Magazine, 4 February 2008)

If Craigslist would take the leap and make the site more visually appealing, I believe we have a User-centric EA winner!

Mind Mapping, Social Graphing, and Enterprise Architecture

User-centric EA uses visualization techniques like mind mapping to brainstorm and develop information products that are useful and useable to the end user.

Mind map—“a diagram used to represent words, ideas, tasks or other items linked to and arranged radially around a central key word or idea. It is used to generate, visualize, structure and classify ideas, and as an aid in study, organization, problem solving, decision making, and writing. It is an image-centered diagram that represents semantic or other connections between portions of information. By presenting these connections in a radial, non-linear graphical manner, it encourages a brainstorming approach to any given organizational task, eliminating the hurdle of initially establishing an intrinsically appropriate or relevant conceptual framework to work within…The elements are arranged intuitively according to the importance of the concepts and they are organized into groupings, branches, or areas. The uniform graphic formulation of the semantic structure of information on the method of gathering knowledge, may aid recall of existing memories.” (Wikiepdia)

Mind maps are all about linking information and portraying it in a simple, clear, and easy-to-read way for people to understand and use.

Similar to a Mind Map that visualizes linked items to a central idea, the Social Graph is “an image of a person's connections to friends, family, and colleagues,” where the person is in the center and his connections (or links) span outward.

MIT Technology Review, on 28 December 2007 reports in “Mapping Professional Networks” that “IBM's Atlas tool aims to help businesses visualize connections between colleagues…[it] works in conjunction with its Connections software, [and] aims to help professionals network more efficiently within large companies. Its My Net component helps people visualize how closely they’re staying in touch with professional contacts. The closer a contact is to the center of the circle, the more frequently the user communicates with her.

The Atlas tool “collects information about professional relationships based not only on job descriptions and information readily available through the corporate directory, but also through blog tags, bookmarks, and group membership. Atlas can be configured to look at e-mail and instant-message patterns, and to weigh different types of information more or less heavily.”

“Atlas's four features are Find, Reach, Net, and My Net. Find and Reach are both focused on finding experts in particular fields. Through Find, a user enters search terms and receives a list of experts, ranked based on information gleaned from social data, the level of the expert's activity in the community, and any connections he may have to trusted associates of the user. Reach then helps the user plot the shortest path to make the connection, suggesting people the user already knows who could put him in touch with an expert. Net and My Net are primarily meant to help people analyze their existing networks. Net shows patterns of relationships within particular topic areas at a company-wide level. For example, it might analyze data on people interested in social computing and produce a map of how those people connect with each other through blog readership and community involvement. My Net allows individuals to analyze their own networks, showing them who they are connected to and how frequently they stay in touch with those people.”

The Atlas tool is a cool visualization technique that organizations can use, for example, after a merger or acquisition to see how well two organizations are integrating or that an individual in the organization can use to locate and stay connected with the subject matter experts they need to do their jobs.

Mind maps and social graphs are two interesting examples of how information visualization can be used to enable better organizational information understanding, analysis, and decision-making. User-centric EA maximizes the use of information visualization to communicate effectively. This is especially true when it comes to senior executives in the organization, who with their busy schedules, frequently look for a quick snapshot of actionable information, which summarizes lots of information for them, and helps them hone in on problems areas or opportunities, and options and recommendations for addressing these. In User-centric EA, Profiles (like mind maps or social graphs) are the high level products that portray a satellite view of information. Profiles capture a broad, strategic view of information and visualize it for executive consumption and decision-making. Further, user-centric EA links profile-level products to more detailed information products in the architecture, like models and inventories, so users can easily navigate up or down the hierarchy of information to get to what they need. Similarly, a mind map or social graph could also be a navigation mechanism to get to more detailed information on the objects or people linked to those products.

Show, Don't Tell - Rule of Thumb #3

Rule #3 is show, don’t tell.

This means that a picture is worth a thousand words. It’s all about using information visualization effectively.

For example, in my agency's network profile, we show a graphic of the United States. We show the nodes on the map, each representing a major communication hub. We show alignment of these nodes to the agency's districts. And finally, we show the connectivity between the nodes, including the type of communication lines.

This network profile can be used, for example, to envision connectivity being disrupted, whether through man-made or natural disaster, and how this would affect mission execution. This is a tool for helping us plan for continuity of operations.
