Web Development Lifecycle (WDL)

The web development lifecycle (WDL) is a more specific variation on the general framework for developing any application development project. Unlike general application development, all web design and development projects follow a similar structure, so the web development lifecycle / process can be drawn upon as a point of reference for both the web development team and the client to determine the status of any given project and the area of activity to address next.

The Web Development Lifecycle is made up of eight identifiable stages described as follows:

1. Initial Consultation

The Initial Consultation seeks to understand the high level business requirements, the scale of the web development, required delivery schedule, and the overall feasibility, web design and cost of the project.

2. Project Specification

The business requirements of the proposed website are iteratively established between the Client and the web design team, and documented in the form of a High Level Requirements Specification. Focus here is on the relevant business rules and outputs. Implementation of the system, how the requirements are actually delivered, is reserved for later. Once agreed, this document will form the basis of the subsequent stages of the Web Development Lifecycle.

3. Web Site Architecture

Here the software and hardware requirements for delivery of the web application are established, such as the most appropriate web and application development language, operating system, database management system (DBMS), and hardware / hosting environment that are most appropriate to support the final website in a robust and reliable manner; taking account of the likely growth of data volumes, visitor numbers web traffic, and functionality.

4. Web Site Design Cycle

Deliverables out of this phase have a particular focus on the web design of the system, include mock-ups or prototypes of the screens that make up the system, combined with system walkthroughs which will enable both the Client and the software developers, designers and project management team to clearly understand how the website will work from the user and administrators perspective. The design of the CRM would also be full considered here also. This web application functionality is considered in the context of the defined outputs and business rules, and may result in the High Level Requirement Specification being updated or changed. Following this, a key deliverable here is a Low Level Website Design Specification / Document precisely defining the required implementation of the web design and forming a blue print of the project for the software developers.

5. Content Collation

Any required textual and graphical content for the web application is developed or acquired by the Client (or the software development company, depending on the relevant situation). Admin functionality which enables the Client to amend the full content of the site from system launch, and on an ongoing basis, is assumed to have been included and defined within the High Level Requirements Specification, as mentioned.

6. Web Site Project development

At this stage a detailed project plan will have been established for the implementation of the web design, resources identified, time scales defined, and project dependencies clearly understood – especially with respect to which parts of the web development can be done in serial or parallel. This stage actually overlaps with the next stage of the Web Development Lifecycle since all web developed modules are unit tested to destruction by the corresponding web development team members. Further, it is very important that all code produced by the software developers is quality checked to ensure adherence to project development standards.

7. Testing & Quality Assurance

Many forms of testing are carried out during this phase, from system and volume testing – in order to ensure that all components work together within the web application and can easily cope with both the initial and anticipated future demands on the system – all the way to User Acceptance Testing (UAT) and sign-off. There are many forms of testing required during this phase that are beyond the scope of this introduction, such as cross-browser and security testing – all contributing towards the delivery of a high-quality website and service to the client.

8. Web Site Deployment (Launch)

Once the website implementation is tested and released by both the client and software development company as being fully operational, the website is deployed to the production environment and open to the relevant user base. Following this there is generally a pre-agreed period of warranty and an ongoing support agreement can be established at the discretion of the client.

The process can vary but, generally speaking, the dependencies and features of a successful process of delivering webs applications to the client does not. I hope this has been a useful introduction to the process of delivering quality web applications to any business.

Web Developers & Designers

Web developers and designers are the people involved in developing Word Wide Web applications or distributed network applications. Web designers are the team of workers that work in close cooperation in order to accomplish client demands. The basic aim of the web application development team is to satisfy client needs in meeting all their requirements. Web developers play an important role in fulfilling client requirements.

They are the software developer or the software engineers exclusively engaged in developing the web application designed by their team. Web developers works on the decision of web designers, in turn the web designers pattern the application according to client’s demand.

Basically, web designers will have good communication with the clients and provide a document on the client’s requirement to development team. The developers work upon the requirement to develop exact result of the final project. Web developers had to work on a particular project in one or more tires based on the size of the development team. Some developers participate in two or more fields in order to complete the project in time. The developers are dissevered, for example a group is assigned to work on the technologies sent to the client and other group can be ascribed to server-side frameworks.

Web designing is a complex process and it requires ongoing activity. The web development team works on the basic aspects of design to bring out expected result. They usually focus on the content of the website, usability, appearance and visibility. These aspects are nothing but the expected ones of the clients. They need their website should contain reliable information. They mainly expect their website should be attractive and user-friendly on which the designers earnestly work on.

Web designing team has certain model which contains steps to be followed to produce tangible product that fully meets requirement of the client. Nowadays, development team uses fourth generation language to develop the web applications which are rich in facilities. At the first phase, the developers work out in producing prototypes. The prototype is built to quickly demonstrate to the customer what the product would look like. Only minimal functionality of the actual product is provided at this phase. The prototype thus developed by the web developers are reviewed by the designer team and forwarded to customer for demonstration. Customer and the developer team virtually sit together side-by-side and gets feedback on the prototype that the developer shows the client.

Once the feedback is obtained they are documented. These requirements become the basic requirement of the actual system. Reviews on prototype are estimated by the web designer team, during each feedback issued by the client. The web exploitation team likes to spend most of its time in development of the web application, as these are closest to recent technologies. The technologies of today are more advanced and rich in its feature. Work of web developers and designers are made easy and the product is delivered to the client in time.
