UX - User Experience - Biz. relevance for SI



1) ECommerce applications:
Whether it is Insurance or BOA or Amex or Ingram or Motorola or Amazon, all companies are being pressured to give review and ratings (amazon, amex, BOA), comparison (progressive insurance), streaming video reviews (amazon) to the end users and analysts.
- This on-line channel of providing enhanced features is not only in demand for web apps but also for iPhone apps or black berry apps; which is big business. BOA recently came up with a free black berry app made in flex or silverlight.
- Streaming video product reviews are now being sold by companies like CNET which requires a company not only to strategise on their search and web content management but also the way to present it. Flash player or Java fx or silver light are major contenders for this business depending on the current infrastructure of the company. This area is still maturing and there are a lot of opportunities in this area.
- Most insurance and banking companies are yet to convert their peripheral apps like stock trading in BOA or profile management in Chase to RIAs.
- Desktop widgets are other applications which are catching good traction in the market. Southwest, Amazon, Google are the early winners in this. Even in this area big vendors have taken sides. For eg SAP Widget toolkit is an add on to Yahoo Widget Toolkit and Yahoo engine (actually a prerequisite.)

2) BI Applications
Companies like Microstrategy (version 9) or BO (Excelcious) have come out with capabilities where in either
- The UI generated by the engine by drag and drop ides is RIAs or
- The development environment demands skills in flex or silverlight or
- The UI to be developed and tweaked is for desktop widgets (for KPI level notifications or alerts.)
Though the first one is not much of a opty from a services perspective the last two can definitely be of value add in the BI domain. As UX is never a focus when strategising BI companies often scamper around for this skillset as it is not in their planning.

3) ISV Capability
Actuate, Pentaho, Microstrategy, BO, SAP or Oracle (any small, medium or big vendor) are companies which are looking for changing the rendering technology of their UI generating engines to be in RIA oriented. For eg SAP is not changing the way we develop webdynpros. But they are changing the engine that generates htmls to give an option to the companies to select between plain html and AJAX. This trend is now being followed by smaller companies like microstrategy or actuate. This is creating new opportunities in product enhancement space. The same eg can also be carried over in other UX based tools like portals or ECommerce engines.

4) Internal apps/Portal apps.
Internal applications and portal apps which face the employees of organizations are being RIAfied in the enterprise pretty regularly now. A quick task approval app in the form of a desktop widget or a mobile app or travel reimbursement app in disconnected and connected mode is very common in the enterprises. Most of these apps are custom and is a huge space for development support services. 

5) Consulting services
- Big companies like Ingram Micro or Motorola or BOA or Amex have different regions in the globe having their own apps. Ingram uses Cold fusion in Asia PAC, YUI in UK, JSP in US and PHP in Germany. Consolidating them to one UX to take competitive advantage of the customer facing channel and showing a single face to the customer is one service a lot of companies need.
- Another service is definitely UX toolset selection and TCO recognition.

Some points to ponder or what I saw customers talking about..
1) Big application vendors have started to take sides with these technologies like SAP is taking flex or Oracle is taking up JSF (they call the enhanced version ADFs), Microsoft with silverlight and lighter weight AJAX in ASP.NET and C#. So for most companies the choice becomes a taken and they just move ahead with what the most affluent vendor in the company suggests as the roadmap.
2) According to some analysts big companies (Dell, AMEX, Visa, HP, Intel etc.) with large on line presence are not using any of these technologies to bare bones. They have matured to a stage where in they have their own frameworks (controls, UI screens, data transformation logic etc) built as a company wide standard. These frameworks are not going anywhere.
3) UX applications are also gaining visibility because of their default scaling capabilities in other channels. E.g. SAP Webdynpro or Flex player requires zero or minimum coding for converting a web app to desk top app or a mobile app.

What lead to advent of cloud computing

Extjs Summary


Pros
  • Commercial and Open Source licenses available
  • High performance, customizable UI widgets
  • Well designed, documented and extensible Component model.
  • Good widgets. ExtJS is a superset of the widgets of all available JavaScript frameworks. With no obvious bugs it is great from a end user's perspective.
  • Good API documentation. If you need to look up something you’ll probably find it.
Cons
  • Applications do not degrade gracefully. Turn off JavaScript and you are left with a few lines on your screen.
  • The CSS. It’s nearly thousand definitions which are giving you no idea which is used for what purpose.
  • The HTML is huge. Many tags get so many CSS styles assigned that you don’t understand what’s going on. DIVs are nested so deeply that you’ll need a minute at least to find a certain widget in Firebug.
  • Issues in loading the start page because of a 500 KB library
  • Development/Customization  effort is significantly high in terms documentation effectiveness & IDE availability.
Cross channel Support
Extjs supports all major web browsers including IE 6+, Firefox 1.5+ (PC, MAC), Safari 3+, Opera 9+ (PC, MAC). Though there are issues when custom DIVs are added because parent child relationship does not render in the same way in all the browsers.
In case of an advent of a new browser one has to depend on the company Extjs as there is no way to customize the existing Extjs APIs.



YUI Pros and Cons


Pros
  • Clearer separation of client and server code.
  • Works very well with traditional page-centric applications(unlike GWT). 
  • Has decent graded browser support.
  • SAP widget toolkit is built around YUI.
  • Controls like Panels, Auto complete, Data table, tab view, slider, pop ups work very well and are easy to implement.
  • Easy to adapt for skilled JavaScript developers.
Cons
  • Lack of good IDEs leads to difficulties at development time for development & UT.
  • Leaves you to manage how to translate your server-side return values to XML or JSON
  • YUI Browser History does not support Opera. This is due to the fact that Opera does not update the `location.hash` property when using the back/forward buttons. It will be corrected in a future version of the Opera web browser.
  • Developers need to use commercially available IDEs to develop applications in YUI. Eclipse plug-in is not free.
  • Issue resolution for YUI library issues is difficult and forum updates not frequent enough
Cross channel support
It also offers two fundamental ideas, a) A broader and more reasonable definition of “support.” b) The notion of “grades” of support. The Graded browser provides an inclusive definition of support and a framework for taming the ever-expanding world of browsers and frontend technologies. 
But considering the way YUI architecture has been designed it is mostly up to the developer to take care of the cross browser issues in case of errors and incompatibilities. But the good point with YUI is as all code is in .js and it is open source, the developers can modify it to fix their problems (unlike GWT).



Is this United States of America???

I was so excited when I thought I will have a california state license. A license valid not only in US but in countries like France and Germany. But I am sad the excitement was short lived and after about 65 days of waiting I am absolutely disgusted with the procedure. I have submitted my documents including h1 approval and I94 and all other documents needed. I have called up DMV like n number of times but no response. 

I guess I am getting a flavor of the real USA. Believe it or not now a days even in India, the small town I come from (Surat) you get license in 1 hr max (if you have the right documents). But I guess this is the down fall of a great country whose attitude and life I have always admired. Forget about India, other states like Ohio or Arizona we get the dirving license in an hour, I wanna ask the authorities why is California so special? This is the worst service I have ever got in america. DMV almost never has ideas on what can be the appx date of arrival or cause of the delay or whats going on in the approval department. People on no. 9166577445 are much more reasonable, but still I had to send him my docs by fax and run around after him. I really felt helpless and like a begger today. Just frustrated and embarased by the situation.
