Development Methodology

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

  • Waterfall
  • Prototype Development
  • Agile Development

System Development Life Cycle Model (SDLC Model)

System Development Life Cycle Model or Waterfall method has the following activities.

  • Software Requirements Analysis
  • Technologies 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 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 member's assignments, price, project plan, and milestones.

System Design

In this software development process, the overall system structure and all details are defined. The system architecture, the database design, the data types are needed to be clarified at this stage. A software development roadmap is created.


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 client. In this methodology, the software is evolved because of periodic information exchange between the client and vendor.

Agile Development

It is a conceptual framework for undertaking software engineering projects.

Properly injecting Agile techniques (Extreme Programming- XP) into development project can add improved responsiveness and business/IT benefit. This methods attempt to minimize risk by developing software in short timeboxes, called iterations, which typically last one to four weeks. Each iteration is like a miniature software project of its own, and includes all the tasks necessary to release the mini-increment of new functionality: planning, requirements analysis, design, coding, testing, and documentation. While an iteration may not add enough functionality to warrant releasing the product, an agile software project intends to be capable of releasing new software at the end of every iteration. At the end of each iteration, the team reevaluates project priorities.

This approach indirectly saves organizations money because it produces higher-quality code that meets client needs, but cost savings aren't typically the key benefit.
