Software Development Methodologies

Software Development Methodologies and Models

The SolveITLabs development team adopts project methodologies based on the client's project specifications and requirements. Following are the basic popular models used by our company:


System Development Life Cycle Model (SDLC Model)

  • Software Requirements Analysis
  • Systems Design
  • Development
  • System Testing
  • Release and Maintenance
 

Software Requirement Analysis

This is also known as feasibility study. In this phase, the onsite/offshore team works with the client together and research 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 member's assignments, price, project plan, and milestones.

 

System Design

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.

 

Development

Programmers write code and perform the unit testing.

 

System Testing

Once the Development phase is over, the software modules needs to be tested all together. Different type of test should be used at this phase depending on the system type.

 

Prototyping Model

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 result and provides feedback. After several number of builds, the complete system is sent to the customer. In this methodology, the software is evolved as a result of periodic information exchange between the customer and vendor.

 

Offshore Agile Development

During the past 2 years, companies have begun to use Agile development processes and offshore outsourcing to realize incremental gains. The benefits that attract companies already doing offshore or companies already doing Agile development are quite different, however, as are the teams' motivations for blending the two processes.

 

Implementing Agile processes in offshore projects

Properly injecting Agile techniques into an offshore development project can add improved responsiveness and business/IT benefit.
To make offshore relationships successful, software teams has to dramatically improve their software processes. For example, customers/business users have had to learn how to specify their requirements carefully and understand that changing those requirements midstream could cause significant cost and time overruns. Many non IT users struggle to deal with these requirements. And their inability to manage with it can eliminate much of the savings the offshore development offers.

Communication takes center approach, between the business users, the internal IT team, and the offshore team. Short iterations force frequent reviews so business people can approve functionality or provide feedback before too much time or money has been spent on that milestone.
Agile development indirectly saves organizations money because it produces higher-quality code that meets customer needs, but cost savings aren't typically the key benefit.
