Since a web system (or site) is always part of a larger system, the work begins by establishing requirements for every system element. This view is essential when softwares must interface with other elements such as a hardware, people and databases.
HAT Development conducts a detailed survey of the functions and business rules and documents a specification of the Web system
The purpose of the specification is to show an overall and general idea of the project being developed. It is made to understand the needs, the coverage and to determine the scope of the project.
In this phase, we generate documents with precision and caution, because the solution is based on this specification. If needed, we developed a working prototype of the system to be validated with the customer.
The requirements gathering process is intensified and focused specifically on the software. The HAT software Engineer (Analyst) must understand the domain (scope) of the information. The requirements are documented and reviewed with the client .
We plan an innovative solution using technologies and tools to meet customer needs. The design of the web system is actually a multi-step process that focuses on four distinct attributes: Data Structure, Software Architecture, Procedural Details and Characterization Interface. As the requirements, the design is documented and becomes part of the web system configuration. HAT Development projects a solution using technologies, software and tools that meet customer requirements. Currently, we work with the following languages and technologies: Java J2EE Web, .Net, ASP, PHP (Various frameworks), Ruby on Rails and Django Python. Also mobile technologies iOS, Android and Windows Phone (.Net) technologies.
HAT Analyst Programmers implement and test the designed solution with quality. The stage of development (coding) performs the task of translating the design into a machine readable form. If the project is well detailed, coding can be almost “mechanically” performed. Analyst Programmers from HAT Development implement and test the designed solution. We provide documents and manuals to the client on installation, configuration, and how to use the system. We provide a restricted page where the customer can follow the whole evolution of design and OS (order of service) during all stages. This allows detailed control and forecast for completion of the project.
We conduct rigorous tests to provide quality and innovation to the system according to customer needs . As soon as the coding phase is finished, tests begin. The testing process focuses on the aspects of the software’s internal logic, ensuring that all patterns have been tested. It also focuses on the external functional aspects, making sure that the external inputs produce real results that reflect what was required. After performing rigorous tests in our own software factory to ensure product quality, HAT Development leads the system to the customer. HAT accompanies the official approval of the product by the customer. This makes it possible to ensure full operation of the system according to the requirements agreed with the customer.
We focus on performing a quality deployment to ensure a smooth operation of your system. Deployment is the stage in the life of a web software, in the context of an Information System cycle, which corresponds, textually, to the software’s passage to production. The deployment process of a very large web system (which is the case of fully integrated web portals) consists of several activities interspersed with each other as possible transitions between them. These activities may occur in the production environment, or in the development environment, the approval environment or both.. HAT Development delivers a ready solution to the client, installing and configuring it according to the hardware and business needs .
HAT Development seeks improving the client’s business with innovative technology based on the Rational Unified Process (RUP) techniques, which are the best project and organizational practices carried out in the market. RUP is a Rational Unified Process that provides techniques to be followed by the members of the software development team to increase productivity growth. It is applied to large designs. Yet, since it is customizable, it can be adapted to any project. Moreover, it has a disciplined solution within a software development organization. The developed systems meet the requirements established with the client. The deployment follows the three-tier Model View Controller (MVC) architecture in order to optimize processes and provide a high performance system.
MVC is a software architecture that seeks to separate business logic from presentation logic, enabling development, testing and support of both separately. The model manages the information domain and notifies the observers of changes. The view shows the model in a proper format and the controller receives the data and responds to the user. The development process consists of eight phases: consulting, specification, analysis, design, development, testing, deployment and support. However, a phase is only initiated when the previous one has been completed
HAT has qualified professionals to offer support/maintenance to your system. Undoubtedly, the software will undergo changes after it is delivered to the customer. These changes may be due to bugs that were found or because the customer required functional and performance additions. The maintenance reapplies each of the preceding stages of the classic life cycle, not the new one. HAT Development has highly trained professionals to perform this maintenance/support of the client’s system. This phase includes adjustments, bug fixes, support, improvements, etc.
Instant start at any time. High quality of services provided . Delivery within the agreed deadline. Low infrastructure cost of the solution developed.. We focus on innovative projects for technology solutions based on the best marketing
