Application development is the connecting bridge that enables an IDEA to complete the journey from conception to reality. Application development is as much about technology as it is about formulating business processes and refining them. Quality application development is the touchstone of identifying an established and mature software company. Developing quality applications has shaped our evolution and we do the whole nine yards of it.
We provide application development in the areas of
Web Application
Enterprise Application Integration
Business Intelligence and Data warehousing

We have a unique process and methodology of providing this quality service. Our methodology for offering application development services is as follows.

Survey: Custom application development needs a proper assessment of the domain of the application, the target audience, and the expected life of the application, current models / applications already in circulation, competition, lacunae / restrictions / limitations of existing systems

Blueprint: This stage depicts the visualization of the application in an abstract manner. We believes in investing time and thought into the design phase, as it will minimize rework and ambiguity at later stages of the development cycle. We are an experienced in adopting the right development model (waterfall, prototype, and spiral) depending on the size, complexity and time to deliver for any custom development.

Development: This stage marks the culmination of all abstract activities including design and architectural framework. This is the critical phase in which the design IDEAs and requirements are given a tangible and perceptible shape. This stage involves a close and tightly knit feedback loop which comprises

Good workmanship and code documentation
Cohesive and focused interaction
Quality Engineers
Validation of the implementation process with the design
Intuitive improvisation when needed
Demonstration of incremental builds for the client to see and analyze.
Development of accurate and relevant test plans strategies.
Maintaining source code integrity through effective code versioning (CVS, VSS etc).

Inspect: At ZSL, our Quality Assurance teams primary objective is to add value to the meticulous efforts put in by the developers. Our QA team has gained a reputation of providing precise unbiased quality services to both our in-house and external QA requirements and projects. Our QA team is well equipped with the state of the art technologies and tools and an approach that upholds the tradition of providing precise and unambiguous quality certification. At ZSL, QA is an iterative process until all the bugs are resolved

Evolution: All applications need handholding and maintenance. There are also instances of evolution of any given project. At ZSL, our evolution and maintenance services involve annual maintenance, maintenance on a need basis and emergency support.
