Software Development

At Rta Technologies we believe that software development should not be restricted to code creation and project delivery. It is inclusive of an accurate comprehension of the client’s requirements and business goals and, on the basis of this comprehension, recommendations of a cost-effective solution with a fine blend of technology. Our highly effective solution recommendations and technology proficiency have made its software development methodology stand apart from its peers.

Rta has supported numerous clients in various product life cycle phases to accomplish their product goals. We have the expertise to begin the project from any of the following stages of product life cycle management:

  • Business Requirement Analysis
  • Ideation and conceptualization
  • Architecture, R&D, and prototyping
  • Design and development
  • Testing and assurance
  • Release management
  • Training and product support
  • Sustenance/maintenance

Rta also work on collective software development methodology. Herein, the client retains its own onsite team, and Rta’s offshore team becomes an extension of this onsite team. These two teams collectively work towards achieving a common goal. We streamline and synchronizes the processes essential for this collective work. In this regard, Rta has implemented the Agile methodology with a highly responsive approach for numerous clients.

Considerations

  • Business problem definition
  • Product development objective
  • Stakeholder viewpoint

Implementation

  • Assemble project team
  • Knowledge transition
  • Define project execution strategies and communication channel
  • Customize offshore process
  • Execute offshore project
  • Review deliverables and identify areas of improvement

Execution

  • Project charter and business case
  • Documentation of user, functional, and system requirements
  • Top-level architecture, technical approach, and system design
  • System decomposition into component and unit specifications and designt
  • Coding, unit test planning, and unit testing
  • Generation of test data for unit testing and system testing
  • System integration and testing
  • Implementation, delivery, and cut-over

These phases are aimed at helping Rta comprehend the company standards, business practices, client requirements, specific IT system environments, and the approach to be followed. The offshore team definitely experiences this comprehension as a learning curve.

We take into account the client-specific requirements and customize the operational methodology accordingly.

Simultaneously, we collaborate with the client to improve the business processes and efficiency. For this, we utilize our past operational experience to recommend the best practices.

We have a thorough understanding of the challenges encountered during software development in various technologies and the established processes and practices required to attain success. To choose the optimum process for projects, we consider points such as type, scope, complexity, technology, and timeline. During a typical software development life cycle, we adhere to the following practices

Requirements engineering

  • Vision statement
  • Elicitation and prioritization of requirements
  • Knowledge acquisition and management
  • Feasibility study or risk analysis
  • Functional and non-functional requirements
  • Safety, security, and performance requirements
  • Buy-in, validation, and approval of requirements
  • Tracing and change control of requirements

Prototyping

We believe that creating a working prototype helps in collecting further requirements from the stakeholders and also enables them to comprehend the system. It also helps in reassuring ideas and defining the go to market feasibility.

Our emerging technology expertise and architectural services capability facilitate prototyping; selection of tools, technology, and framework; and defining of benchmarks. Moreover, this prototyping exercise also considerably decreases requirements and design errors, including UI errors.

Architecture and design

The key is as follows: selection of an appropriate architecture for the application, a good design of the application, and finally, a good representation of the design. Our design team is equipped with extensive knowledge and understanding of industry-standard architectures and best practices. The team adheres to the following fundamental principles:

  • Good designs require in-depth application domain knowledge
  • Only what is hidden can be changed without risk (hence, it is important to expose interfaces and hide implementations)
  • Separation of concerns leads to standard architectures
  • Reusing designs through patterns yields faster implementation and better maintenance. The output of a design activity is a technical plan or blueprint of a system that helps the developers construct the system.

System construction

A set of activities that transform a design into a running system is termed as ‘construction’. This phase requires the engineering teams to adhere to the following principles:

  • Well-structured programs have fewer errors and are easier to maintain
  • Software-reuse decreases cycle time and increases quality and productivity
  • Adherence to Agile methodology decreases the effect of change in requirements

We emphasize on robust coding standards, useful code comments, and extensive unit testing during the course of system construction. We urge our teams to practice test-driven development, continuous integration, and short build cycles.

Review and verification

We believe that error prevention is better than error removal. This implies that inspections result in significantly increased productivity, quality, and project stability. Therefore, our construction phase is composed of review and inspection of the design and code. During review, if some issues are identified, we amend them. To avoid repetition of identical errors, we share the learning across the team.

Testing and Quality Assurance

Testing is an integral part of the software development process. Our project plan is accompanied by a test plan. We develop test cases during the designing and coding of an application.

To ensure that the delivered system is of the best quality, we promote random testing and bug bashes. The basic principle behind these activities is that ‘formal testing can show the presence of errors, but not their absence’.

Governance

During all phases of software development, we continually monitor the progress of our efforts and tune our processes. These activities encompass project management, configuration management, requirements and change management, and quality and defect management.

Our extensive use of Software Application Lifecycle Management (ALM) helps us track and monitor the different areas of requirement management, software architecture, development, software testing, software maintenance, change management, continuous integration, and release management.


Software Maintenance

In the current environment, business practices, policies, and execution methodologies keep undergoing changes even as newer and better technologies emerge. In such a scenario, one of the biggest challenges faced by organizations is to manage IT well enough to keep it in sync with the business, while capitalizing on current assets.

Software maintenance is one of the important phases of a product lifecycle. It represents the improvements made to the existing software to provide a competitive edge in any industry. Rta helps you in accomplishing the task with its proven approaches to application/product maintenance through maintenance or end-client specific releases. The range of these maintenance activities is from small fixes for existing defects to implementation of new business rules in an established product.

Rta executes well-planned knowledge transition and product ramp-up processes to confirm that the offshore team completely understands the client’s product and business standpoint. If any changes are proposed to a system, Rta does the impact analysis of these changes using its proven skills. The outcome of this analysis is used to project the propagated effects to the other parts of the system. In any maintenance project, the impact analysis phase is important because it helps comprehend the effect of the design change and release on the product. Consequently, the client can make an informed decision regarding the implementation of any change.

Categories

  • Offshore and onsite maintenance
  • Bug fixing and troubleshooting
  • Bug tracking and reporting
  • Fine-tuning of the product functionality
  • Research, design, and implementation of new features

Considerations

  • The performance of the software must be maintained (perfective maintenance)
  • The errors in specifications, design, and implementation must be corrected
  • The final product must also evolve to existence (evolution maintenance)
