Z Info Solution uses a proven methodology to consistently produce application development solutions for our clients. Our methodology is founded on principles of the agile development. We have adapted these approaches to the requirements of application development in a highly collaborative environment. The result is an approach that facilitates rapid, incremental development, helping our clients to mitigate risk, lower lifecycle cost, and speed time to deployment. Application development outsourcing ensures that geography no longer poses a hurdle, through leveraging upon a 24×7 global delivery model.
Key features of our custom application development approach include:
- Agile-based process-oriented development principles
- Almost-zero black box approach for involving clients from end-to-end stages of the development cycle
- Predefined methodologies and frameworks
- Structured and managed requirements definition process
- Focus on quality
- Rigorous program management processes
- Effective communication and collaboration processes
Z Info Solution follows the 4D methodology for custom application development:
In the Define phase, we define the expectations and requirements for the desired solution. Through investigative discussions with the client, Z Info Solution facilitates the creation of a comprehensive plan which is based on a solid understanding of the client’s business goals of application development and constituents that shall enable the achievement of such goals. The Define phase typically addresses the following major areas:
- Business process
- User experience
- Integration points
- Location of development work
- Organization of teams
- Measures of success
The Define phase provides the foundation on which application design is built. Depending on the complexity of the solution to be developed, the deliverables of this phase encompasses:
- Project plan
- Use case model
- Software requirements specification
- Risk management plan
- User experience framework
- Logical architecture diagram
- Integration architecture diagram
- Quality assurance plan
- Project administration plan
- Communication plan
The Design phase focuses on three key elements: content, functionality and usability. Other areas addressed in this phase include support and maintenance requirements, resulting hardware/server/database impact, and overall performance and cost issues.
- Functional Design
The first design activity is the development of a high-level, structural view of the Web application. This step focuses on determining the content and functionality necessary to meet established business requirements. It is often facilitated by a Joint Application Design (JAD) session between Z Info Solution and client project teams.
- Technical Design
Guided by the functional design, Z Info Solution’s team will create a detailed application design. Once complete, the templates, graphical elements, and custom code modules necessary to implement the high- level design is initiated. Standards, features, graphics, database connectivity and dynamic report generation are agreed upon during this phase to ensure that users will be able to effectively view and navigate the site depending upon the usage environment. An acceptance test plan is developed as part of the technical design that thoroughly outlines the testing procedures for the system prior to deployment.
Development is generally performed on a separate development system housed at a Z Info Solution facility as part of our global delivery model. Z Info Solution mirrors the client’s environment to ensure smooth integration. Alternately, depending upon the client requirements, Z Info Solution can provide expert resources at the client site in order to carry out the process.
During the Develop stage, integration and setup of all hardware and software required to support the application, including the appropriate operating system, server, and database systems is carried out. This phase also includes a thorough integration, system, functional and acceptance test stage that ensures that the application performs according to its design and quality specifications. Z Info Solution uses a proprietary Agile-Based Client-Driven (ABCD) development approach that focuses on creating client delight through early and continuous delivery of valuable software using Agile practices.
Final deployment of the solution includes setup and testing of all application components developed by Z Info Solution at the client’s facility, as well as any required training on the application’s use and operation. Our acceptance procedures include performance testing services encompassing review of architecture and usage, predictive modeling, stress testing, and detailed analysis and recommendations.
