How does it work?

These are the 4 essential aspects to deliver comprehensive solutions with high quality standards in the shortest time possible.

  • Analysis and Budget
  • Agreements and KPI's
  • Development Life Cycle
  • KickOff, Support, Maintenance

We will have a physical or virtual meeting to understand your needs, make the technical feasibility, define the scope to have the necessary information and provide you with a free quote with the solution that best suits your initial need.

Are you not clear about the tools? We have technical advice at your disposal to guide you in the process to find the best solution to your requirement.

Once the contract is closed, we will have the work team who will be in charge of developing your application under the agreements and KPI's that were agreed upon. We will assign the design and programming tasks and get to Work!

By using an agile methodology, we seek to optimize the project life cycle as much as possible. For this reason, the project will be divided into small prototyped deliveries where we will present the progress corresponding to each one, so that we can easily make an adjustment if necessary. You are part of the team!

Unfortunately all good things must end. The process was rewarding for all parties and now it is time to deliver the final version to you after a rigorous series of tests and quality control.

You will receive all the test scenarios, the source code, the functional and technical documentation so that your solution is duly registered in case of need.

Finally, we want to form long-term professional relationships, that is why we offer you the possibility of acquiring a corrective maintenance contract so that your solution advances and is competitive in the market.
