Objexx Engineering

Technical Software Development

Development work at Objexx is carried out with an efficient process and a breadth of skills and experience. Smart choices of languages, tools, and milestones provide a solid foundation for on-time delivery of excellent solutions. Object-oriented design is used where it can enhance code quality and flexibility. Algorithms are crafted to meet challenging technical and performance requirements and implemented in cross-platform, standard-compliant code. Testing and designing for testability are intrinsic to the Objexx development process.

Agile Process

Objexx uses an agile development process to ensure efficiency and to afford clients early and frequent feedback on progress. Some of the key aspects of this process are:

  • Frequent milestone deliverables of increasing functionality.
  • Lightweight requirement and design changes.
  • Unit tests and mock components are developed along with the application code.
  • Regular client engagement and feedback.

Object-Oriented Design

Object-oriented solutions can be built to provide highly modular, robust and testable systems. Knowledge of best practices and the tradeoffs of object-oriented design patterns and techniques assure sound, well-engineered solutions.

Testing

Test-driven development is intrinsic to an agile process. Unit tests are built along with application components. Live (assertion) tests are used to check class invariants and function pre and post-conditions. Static and dynamic testing are part of the regular QA process.
