Web Development Life Cycle

Software Processes and Quality Management are building blocks for scaleable Custom Website Applications.

Dassnagar Infosystems is a process centric Indian Web Application Development Company, that builds scaleable custom website applications with potential to transform into robust Portals with plug and play modular architecture and sustain high traffic without any performance degradation issues. Their is one thing common between a Myspace (social network), Youtube (video broadcasting) and tigerdirect.com (B2B Supply chain Portal), they all started as websites and then went on to become successful in terms of traffic and performance other than niche concepts. Portals are not developed overnight, rather they all start as a web site that moulds into a Portal. However this transformation is possible only when the Software was engineered with provisions for scaleability and a strong conceptual model has been put into practice. This makes Software Engineering and Database designing (relational database designing for data concurrency) immensely important and only Software Development Companies with proven SDLC Life-Cyle and quality management framework can offer scaleable solutions. SDLC also ensures that the company has a segregated process control and thus can handle a custom concept by breaking it and dividing in various tiers to finally develop an N-tiered architecture backed by efficient quality assurance checks.

By Definition "Software Development Lifecycle" (SDLC) is a conceptual model used in Project Management that defines stages involved in a software development project and gives better control on the software development process. The most commonly used SDLC models are Linear Sequential Model, Prototyping Model, Rapid Application and Development (RAD) Model, Incremental Model, Win-Win Spiral Model, Concurrent Development Model, Formal Methods Model, Joint application development (JAD), foundation model, build and fix, synchronize and stabilise. Software Development Companies have tailored SDLC Processes to come up with their own custom models propreitory to the organisation. The solidarity of the SDLC methodology is fundamental to growth of a software development company.

Communication and Evaluation of Web Applications

From a customer view point, every web application development project constitutes three major phases :

Web Designing Phase (also termed as Graphical User Interface Design) : Process starts with custom home page layouts based on Designer's Query Form feedback by client. Various concepts are shown and then any one is finally choosen and refined till client is fully satisfied. Their is no limitation in the number of editing that client can ask. Following Home Page Approval, all inner pages are prototyped and client evaluates them. The entire evaluation process is online through our Test Servers and tracking is done using Bug Tracking Software that is a part of our Project Management.

Business Process Analysis : An alternative team of System Analysts prepares SRS (System Requirements Specification) through a series of email and chat sessions with client. The final Objective is to document client's business model (business process logic and constraints) into software process logic and finally come up with the software specifications. The Software Engineering is done based on SRS approved by client.

Web Designing and Business process Analysis are parallel operations and usually completed within 4 weeks.

Web Application Development Phase (also termed as programming stage) : The Process starts on availability of Approved SRS (System Requirements Specification) Document. Our Software Architect team prepares High Level Software Architecture based on SRS, and then Low level (modular) Software Design is prepared by Project Manager and or team leaders. Sophisticated Case Tools like Rational Rose, Visio, Clear Case are used for detailed software architecture designing with reference to High Level Software Architecture. The documents are sent to QC for formal check up and on clearence Project Scheduling is done to distribute coding and cross module unit testing. Each developer is responsible for unit testing and finally the complete project is sent to Quality Assurance for performance load testing.

During this process evaluation is in stages as per Milestone Monitoring Plan. Portions that have been completed are uploaded to client provided LIVE web server (access restricted by Fixed IP) for stage evaluation. Corrections are carried out based on feedbacks. Through this iterative life cycle we reach a stage where the software is defined to be bug free. This is termed as Beta Launch. Configuration Manager fine tunes the site based on Beta Feedback and the site is finally ready to be delivered. To know more, please email us at , or call +91 9831262564.

All "Web Applications" come with 3 months free support and 12 months warranty on software.
