We discuss key requirements with you and prepare documents to outline them, including supported features and proposed end results. For that, the following points are considered.

  • Identification of stakeholders and sponsors.
  • Infrastructure Requirements.
  • Security-related information and gathering.
  • Service Level Agreements and their conditions.

Once we collect the above information we will also estimate the time and cost of the project. This detailed analysis will help to decide whether you can do the project or not.


After the concept is outlined, the software development team reviews your project and selects the necessary tools and resources for it.

Here are the things we consider grants.

  • Discuss with the team and identify technical and logistical issues.
  • Define Iteration span Time.
  • Creating stories for estimation.
  • Resource planning for both Development and QA teams.


It tends to be the longest phase as the bulk of the work is carried out here.

  • Developers combine all product requirements and customer feedback with UX designers to create design code.
  • The goal is to build the bare functionality of the product by the end of the first sprint.
  • Additional features and modifications may be added in subsequent iterations.

This phase allows software developers to quickly create working software and make improvements to satisfy the client.


Complete our team's major effort and time estimates. We have to spend more time on this.

  • Coding.
  • Unit Testing.
  • Execution of Manual test scenarios.


The product is almost ready for release. But first, the quality assurance team needs to run some tests to ensure that the software is fully functional.

  • These QA team members will test the system to ensure that the code is clean – if potential bugs or errors are discovered.
  • User training will also take place during this phase, which requires more documentation.

When all of this is complete, the final iteration of the product can be released into production.


Once you get the software completely, we move you to this maintenance phase.

  • Ongoing support will be provided to keep the software running smoothly and fix new bugs.
  • Provide additional training to users and ensure they know how to use the product.
  • Over time, refresh the existing product with improvements and additional features.
