Appreciation From Clients

Frequently Asked Questions

On average, app modernization ranges from 1 month to 12+ months. However, application modernization depends on the complexity of the existing application, complex architectures, and the technology solutions chosen to migrate your application.

Our primary goal during the modernization process is to ensure minimal disruption to your business operations. We achieve this by using strategies like phased rollouts, where changes are implemented in stages rather than all at once. This allows users to adapt gradually and ensures that any issues are isolated and addressed steadily.

Additionally, we often use parallel environments, meaning the modernize legacy applications are developed and tested alongside the existing ones. Only when the new system is fully ready and vetted, will we replace your app. Through replacing applications and re-engineering processes, we ensure a smooth transition and continuous business operations.

Security is important in every step of our modernization process. During the app modernization, we use secure development practices, ensuring that the application is free from vulnerabilities. We utilize tools to scan and identify potential security threats. Post-modernization, we conduct comprehensive security audits and penetration testing to ensure the application’s robustness against potential attacks. Additionally, we stay updated with the latest security trends and threats, ensuring that your application is always protected as per new digital capabilities.

We believe in transparent communication and regular updates to ensure our clients are always in the loop. Here’s how we keep you updated:

  • Weekly/Bi-weekly Meetings: We schedule regular check-in meetings to discuss progress, address any concerns, and gather feedback.
  • Progress Reports: We send detailed progress reports outlining what has been accomplished, upcoming tasks, and any potential roadblocks.
  • Dedicated Point of Contact: You’ll have a dedicated project manager who will be your primary point of contact, ensuring consistent communication.

Yes, we believe in collaborative efforts and value the insights and expertise your in-house IT team can bring to the table. They have an intimate understanding of the existing system and business processes, making their involvement invaluable. We can work closely with them, from the planning phase to execution, ensuring that the modernization aligns perfectly with your business objectives. Whether it’s in decision-making, testing, or deployment, we welcome and encourage the active participation of your IT team, ensuring a successful modernization journey.

We understand that requirements can evolve over the course of a project. Here’s our approach to changes:

  • Flexible Development Approach: We adopt agile methodologies, which are inherently flexible. This approach not only allows for the integration of new features as the project progresses but also helps in strategies that reduce costs in the long run.
  • Change Request Process: If you have a change request, you can communicate it to your dedicated point of contact. We’ll assess the impact on the timeline and budget and provide you with an updated estimate.
  • Feedback Loops: Regular feedback sessions ensure that the project aligns with your vision and allows for timely adjustments.
