I had an absolutely good time working with Space-O. They genuinely impressed me initially with the interface designs and consistently followed through with constant internal communication and robust programming. I would like to work again with Space-O in the future. If I could hope for anything more, it would be to have the project completed a sooner.
FAQS About Application Modernization
What’s the typical cost and ROI timeline for application modernization?
Application modernization costs typically range from $25,000 to $75,000 for basic projects to $75,000 to $300,000+ for complex re-architecting, depending on scope and system complexity. Most organizations see ROI within 12-18 months with 30-50% operational cost reduction. We provide transparent pricing and ROI projections during the discovery phase.
How do you handle legacy systems with poor or missing documentation?
We use specialized discovery processes for undocumented systems, employing automated code analysis tools to map dependencies, identify business rules, and document workflows through reverse engineering.
Whether you need basic software product modernization services or comprehensive cloud application modernization services, our experts collaborate with your team to understand system functionality. This comprehensive discovery typically adds 15–20% to the project timeline but ensures accurate modernization without losing critical business logic.
How do you measure and guarantee successful modernization outcomes?
We establish clear success metrics during planning, including performance benchmarks, cost reduction targets, and user experience goals. Our testing validates that modernized applications meet agreed specifications through rigorous quality assurance.
We provide detailed before-and-after comparisons covering response times, costs, and security improvements. While business outcomes depend on external factors, we guarantee technical delivery and offer post-deployment support with remediation within 90 days.
How long does it take to modernize the application?
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.
How long does it take to modernize an application?
Application modernization timelines typically range from 1 month to 12+ months, depending on project scope and complexity. Basic software product modernization services like UI updates take 1–3 months, while comprehensive legacy app modernization involving re-architecting can extend to 6–12+ months.
How will our business operations be affected during the modernization process?
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.
How do you ensure the security of my application during and after modernization?
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.
How will you keep us updated on the progress of the project?
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.
Can our in-house IT team be involved in the modernization process?
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.
What If we need any changes in the app solution?
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.
