Software Development Methodologies and Models
Tri-Force’s development team adopts project methodologies based on the client's project specifications and requirements. The following are the basic popular models used by our company.
System Development Life Cycle Model (SDLC Model)
System Development Life Cycle Model or Waterfall method. This has the following activities.
- Software Requirements Analysis
- Systems Design
- System Testing
- Release and Maintenance
Software Requirement Analysis:
This is also known as a feasibility study. In this phase, the onsite/offshore team works alongside the client and researches their system. The vendor investigates the need for possible process automation in the project. By the end of this phase, the team creates a document that has the specific recommendations for the proposed system. It also includes the team members’ assignments, price, project plan, and milestones.
In this phase, the software development process, the system overall structure and all details are pre-defined. The system architecture, the database design, the data types and structure design need to be clarified at this stage. A software development roadmap is created.
Programmers write code and perform the unit testing.
Once the Development phase is over, the software modules need to be tested all together. Different types of tests should be used at this phase depending on the system type.
This is a weekly/bi-weekly build version of the development. In this model, once the requirement analysis and design are completed, the development process starts. Upon completion of the prototype creation, the client reviews the results and provides feedback. After several numbers of builds, the complete system is sent to the customer. In this methodology, the software evolves as a result of periodic information exchanges between the customer and the vendor.
