Custom Software Development

No two businesses are the perfectly same, so can’t be the business and IT solutions for them.

The software solution that works for others may not work as effectively for your businesses. Instead of changing the business practices that are already streamlined, it makes a perfect sense for a business to go for the tailor-made or custom software application development. Custom application development is nothing but the software made or application developed as per the requirements of the client applicable for that particular business needs.

We have delivered custom web, mobile and enterprise applications for various industries by utilizing some of the most popular web software technologies – Java, PHP and Android, iOS & Windows mobile platforms.

Custom Software Development Model

Our custom software development model consists of the following three phases:

Requirements & Pre-Sales

The requirements and pre-sales phase involves:

Requirements Gathering

The Parity sales team conducts a joint discussion with the client to understand the background and key business objectives sought from the engagement. Based on these discussions, Parity and the client jointly identify possible re-engineering opportunities for which Parity can build business solutions that not only drive value but also streamline processes for end users.

Project Finalization

Upon refining the requirements collected from the client, the Parity team presents an engagement plan that details the suggested team structure, technology platform and development process to be followed along with the milestones and estimates for various activities. Once the customer signs-off on the contract, the development and execution phase begins.

Development & Execution

The development and execution phase involves:

Requirements Analysis

Experienced business analysts and project managers from Parity study the functional and non-functional requirements and frame detailed technical documentation for the engineering team to build appropriate systems. This documentation represents the contract between the project team and the customer. Each requirement is tagged with a unique ID to help track and verify development progress from its initial definition to final testing.

Project Planning

Parity follows three principal development methods namely Agile, Waterfall and V-model while executing projects. The selection of the model depends on the type of project and the stability of client requirements. Once an appropriate development strategy is chosen, the project manager prepares a project plan that details scope, milestones, risk management strategies and tracking and control mechanisms. Milestone driven schedules are created for each team role to ensure delivery is as per committed timelines. The quality assurance team also begins outlining the types of tests to be performed including resources, tools and responsibilities for test related activities.


In this stage, the engineering teams prepare detailed architecture designs, class diagrams, entity relationship diagrams and database designs. Moreover, wireframes conforming to project requirements are made using Pencil or Visio.


Post the design/architecture stage, the development of code commences. Project managers enforce Test Driven Development (TDD) and code review as a critical part of the project development process. This ensures that the quality of coding conforms to industry best practices and that the code is readable, clean and maintainable. The completion of each module results in the preparation of test cases and unit level testing.

Quality Assurance

Once the application is ready, the Quality Assurance team tests the application using manual and automated methods against various test cases, test plans and user acceptance criteria. In addition to unit and functional testing, integration testing is performed by combining the various modules and testing them end-to-end. The application is also tested for cross-browser support as well as for performance under peak load and stress.


Parity also offers ongoing application maintenance and support services such as functional enhancements; bug fixes; performance optimization; modification or update of supporting utilities; localization; integration of data management or backup services; infrastructure upgrade and database migration services.
