Website design entails a lot more than just the looks. Conforming with the latest design trends will not guarantee that a website will be termed efficient and effective. This may be because the initial design was not tailored to meet the functions of the organization. The website will focus on readability and usability keeping the users in mind.

The website will be made responsive to allow for support on multiple devices ranging from mobile phones to laptops and desktops. Responsive tables, navigation menus will allow for ease of usage. Maintaining simplicity by ensuring users do not overthink, can easily access content and the text and fonts used should be visible.

In the design, agile technologies including R.A.D and J.A.D will be used. In RAD, a prototype generation approach is used to create a general impression how the actual product will be. There are a series of steps to be followed in this model:

  1. Planning here the design, project scope and requirements will be agreed on to allow for prototyping to begin. The current situation is analyzed, and the requirements finalized. Thereafter, permission will be sought from relevant authorities to allow for the process to continue. The main objective is to understand the problem at hand. Information is gathered by meeting with the management.
  2. User Design Feedback is gathered from the user, analyzed aiming at providing a clear picture of the architecture of the system. Interaction with users, prototypes and models are built. This may be repeated as the process continues.
  3. Rapid construction Here the actual coding, testing and application integration is done. This step can be repeated to suit new changes or needs of the organization.
  4. Cutover This is also the transition stage. The application will be moved from testing mode into live production. Data conversion is done, testing in full scale, complete system changeover and users are trained on how to use or work with the system.

Another technology is the Joint Application Development (JAD). Here JAD sessions are conducted and the end user is involved in the process of design and development. Since the customer ids directly involved the process is faster and customer satisfaction is assured. This model has various participants:

  1. Executive sponsor This is the ultimate decision maker, charters the project and is the owner of the system.
  2. Facilitator Ensures that the meeting agenda is kept. Focuses on directing traffic. Responsible for organizing activities, must have good communication skills.
  3. User Helps in driving the changes, are the focus and provide with business expertise.
  4. Scribe clarifies points and ensures they are corrected accurately.
  5. Observers Watches and learns what the users want. Also interacts with the various parties involved.

Numerous interviews with the client provides input for the development of the system. The stages involved include:

  1. Planning Here the need for developing the system must be identified. The executive sponsor designated, team members selected, and scope of the system is defined. Also the problem to be solved is identified, discussed and results documented. Risks identified and methods on how to curb them.
  2. Preparation Here sessions for design are scheduled, materials prepared, training of team. Session agenda is drafted.
  3. Design sessions The project scope definition, objectives are reviewed. System requirements and interfaces are identified, and prototypes are developed.
  4. Finalization here the design documents are completed and signed off, presentation is made to the executive sponsor, the prototype is demonstrated. Executive sponsor approval is needed to proceed.

Differences between RAD and JAD

  1. RAD is not as structured as JAD and focuses more on development of software compared to JAD.
  2. JAD is better in new systems while RAD focuses on dealing with problems encountered on an existing system.
  3. Its hard to measure progress in RAD technology compared to JAD.

Conclusion

JAD methodology takes into account the user needs hence leads to development of a user centered application and since the target is to develop an attractive and usable website, JAD plays a major role in incorporating user feedback. RAD on the other hand allows for prototyping where users can see a model on how the actual system will operate.
