Custom Application

Custom Software Application

We have delivered custom web and enterprise applications for various industries such as insurance, telecommunications, online advertising, document management, logistics and travel by utilizing some of the most popular software technologies viz. Microsoft .NET, Java, PHP and Ruby-on-Rails.

Custom Software Development Model

The custom software development model followed by PennyWise consists of three phases:


REQUIREMENTS & PRE-SALES

The requirements and pre-sales phase involves:

Requirements Gathering

The PennyWise 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, PennyWise and the client jointly identify possible re-engineering opportunities for which PennyWise 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 PennyWise 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 AND EXECUTION

The development and execution phase involves:

Requirements Analysis

Experienced business analysts and project managers from PennyWise 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

PennyWise 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.

Design/Architecture

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 Balsamiq, Pencil or Visio.

Development

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.


MAINTENANCE

PennyWise also offers ongoing web 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 using AWS; infrastructure upgrade and various .NET and database migration services.
