Web 2.0

The promise:- Oriented around the end user- End users actively contribute to applications on the Web- Situational Applications help the long tail

Applications that would never be dealt with by traditional IT Often built by the end users themselves

In practice- End users contribute content

Blogs, sites such as You Tube, Flickr, etc.

- Lack of contributions of applications Application development still requires programming Tools exist to simplify the effort

- Improve programmer productivity



Today’s Times

• Much is changing• New customer demands, new business models, emerging economies

• Financial Challenges• Global economic shifts, erratic fuel prices

• Can be still profitable• IF, one responds to the above challenges

• However• IT still not productive enough• IT focused on strategic applications

• Web 2.0 paradigms could have helped• Many applications need only be “good enough”• Users want to be self sufficient• Many tools require to much “programming”• Other tools and technologies are not scalable enough

• Microsoft Excel is great unless many need to update the spread sheet

Goal Driven Development (GDD)

A development process in which the user’s end goal is in the center All non-goal related details are hidden

- Especially technical ones

GDD Tools:- Are Goal oriented- Are targeted at a specific user set- Have a set of abstractions and metaphors specific to the problem being solved- Are easy to use



Target User Roles

Mix of business and IT goals. IT part of their role, but work closely with the business users. Need to quickly turn around applications for their internal customers.

Skills – Web technologies – HTML, XML, CSS, Script (JavaScript, VB, LotusScript). Domino developer. Not a Computer Science Major. Could be a system admin.

Business DeveloperBusiness Developer

IT focused. Build anything to meet the business sponsors needs. Don’t want to focus on the smaller projects, in general.

Skills – J2EE (Java, JSP, Portlets, Servlets, EJBs, Database). Use WID. Can build anything they need. Computer Science major. Understands object oriented programming techniques.

Professional DeveloperProfessional Developer

Business goals only. Trying to get their job done. Applications or solutions are a means to an end. May want the ability to customize their environment using non-IT tools.

Skills – experts in their business tasks, use computers, browse the web, but no development skills, even HTML. No desire to learn either.

Business UserBusiness User

Business goals. Department ‘guru’. Can use more sophisticated tools to enable Bus to accomplish tasks. Often needs to automate repeatable processes.

Skills – experts in the business, not a developer type but understands technology and is willing to spend a certain amount of time to learn the tools if the payback is quick and large enough.

Freedom – A set of Web Application Development Tools

7



Freedom IDEs

Are all web based- No lengthy install- User can immediately try and get feedback

Easy to use- Simple things are very simple- Functionality scales with moderate extra effort

Hide appropriate details from the user- Different tools expose different levels of abstractions- Freedom Templates

Only points of variability are exposed

- Freedom Composer Only the contents of the form being built is exposed

- Not even the “Submit” button is exposed



Freedom IDEs

Based on Web 2.0, AJAX based technology- RIA experience- More responsive to the user- Lower load on the server

Work with an application meta model- Application specific artifacts generated from templates on the server- Easily tailored to a specific deployment scenario



Demo: The Alligator Banking Corporation Silver Asset Program

• Jane Smith is the district manager for the Alligator Banking Corporation Bank (ABC Bank), a bank with branches throughout Florida and Georgia. Jane Smith is responsible for forty branches in southeastern Florida.

ABC Bank had developed a Silver Assets program for its baby boomer customers

Jane decided that her district would go one step beyond the Silver Assets program and institute a breakfast seminar series on investing for retirees. - Asked each of the forty branch managers to work with:

Potential customers Local organizations that serve well off seniors (e.g. museums, golf clubs) Locations that can hold monthly breakfast meetings

- Breakfast seminars should be organized by the local branch reps. Agreement with local providers should be approved by the branch manager and a breakfast seminar should be approved by Jane

- Jane would like to receive reports on event participation and new bank customers resulting from the event.



Freedom – Human Based Workflows

Various business processes are built around forms.- A form is “submitted” and subsequently handled by many people

Most tools today reflect the “State Diagram” of the process- In an XML file that needs to be written- In a GUI in which you use boxes, circles, and arrows to draw a state diagram

Freedom has a different approach- The user simply works with the form- Declares what happens when buttons are pressed
