Development Process


Extracting the requirements of a desired software product is the first task in creating it. While customers probably believe they know what the software is to do, it may require skill and experience in software engineering to recognize incomplete, ambiguous or contradictory requirements.

Specification is the task of precisely describing the software to be written, in a mathematically rigorous way. Specifications are most important for external interfaces that must remain stable.

The architecture of a software system refers to an abstract representation of that system. Architecture is concerned with making sure the software system will meet the requirements of the project, as well as ensuring that future requirements can be addressed.



In this phase the system and software design is prepared from the requirement specifications which were studied in the first phase. System design helps in specifying hardware and system requirements and also helps in defining overall system architecture. The system design specifications serve as input for implementation phase.

On receiving system design documents, the work is divided in modules/units and actual coding is started. Since, in this phase the code is produced so it is the main focus for the developer. This is the longest phase of the software development life cycle.

We use best in the industry open source products like PHP, mySQL, Linux and various other well known technologies to develop effective and flexible solutions.


Testing Quality

After the code is developed it is tested against the requirements to make sure that the product is actually solving the needs addressed and gathered during the requirements phase.

During this phase all types of functional testing like unit testing, integration testing, system testing, acceptance testing are done as well as non-functional testing are also done. After successful testing the product is delivered / deployed to the customer for their use.

As soon as the product is given to the customers they will first do the beta testing. If any changes are required or if any bugs are caught, then they will report it to our engineering team. Once those changes are made or the bugs are fixed then the final deployment will happen.

Testing Quality

Training & Support

A large percentage of software projects fail because the developers fail to realize that it doesn't matter how much time and planning a development team puts into creating software if nobody in an organization ends up using it.

People are occasionally resistant to change and avoid venturing into an unfamiliar area, so as a part of the deployment phase, its very important to have training classes for the most enthusiastic software users (build excitement and confidence), shifting the training towards the neutral users intermixed with the avid supporters, and finally incorporate the rest of the organization into adopting the new software.

Users will have lots of questions and sometimes whant new features which leads to the next phase of software.

Training & Support


Maintaining and enhancing software to deal with newly discovered problems or new requirements can take far more time than the initial development of the software.

Not only may it be necessary to add code that does not fit the original design but just determining how software works at some point after it is completed may require significant effort by a software developer. Most part of all software developer work is maintenance. A small part of that is fixing bugs. Most maintenance is extending systems to do new things, which in many ways can be considered new work.

We offer Service Level Agreements (SLA) to provide great service to our customers for fairly affordable prices.
