Frequently Asked Questions
What should organizations consider before investing in application modernization?
Organizations should evaluate business value, application condition, dependencies, operating costs, risk, and future requirements before selecting a modernization approach. This provides a clearer basis for prioritizing investments.
Which applications should be prioritized for modernization?
Applications should be prioritized when their business importance, operational risk, maintenance costs, dependency complexity, or limitations on growth make modernization worthwhile. A portfolio assessment can help organizations compare applications before committing significant resources.
What factors determine application modernization costs?
Modernization costs are influenced by application complexity, dependencies, architecture changes, data migration, testing, integration requirements, available skills, and the delivery model. Portfolio analysis and cost-benefit assessments can provide a more realistic view of the required investment.
How can organizations measure application modernization ROI?
ROI should go beyond infrastructure savings. Organizations can measure maintenance costs, delivery speed, operational efficiency, risk reduction, scalability, new revenue opportunities, and the cost of continuing to operate systems with existing limitations.
Does application modernization require completely rebuilding legacy systems?
Not necessarily. Organizations can choose to rehost, replatform, refactor, rearchitect, replace, retain, or retire applications based on their business value, technical condition, dependencies, and future requirements.
How should organizations choose a modernization strategy?
TThe right approach depends on the application's condition, business value, technical limitations, risk, and expected outcomes. Common options include:
- Rehost: Move the application with limited changes
- Refactor: Improve the existing code and structure
- Rearchitect: Address deeper architectural limitations
- Replace: Move to a solution that better meets business needs
What metrics should be tracked after application modernization?
Modernization should be measured by business and operational results rather than project completion alone. Key measures include:
- Operating and maintenance costs
- Release frequency and delivery time
- Application performance and availability
- Scalability and integration efficiency
Should application modernization be completed all at once or in phases?
A phased approach can limit disruption and give organizations an opportunity to validate results before expanding the program. High-priority applications can be addressed first, with measurable checkpoints used to track progress and guide further investment.
When should organizations consider an external application modernization provider?
External support can be useful when internal skills or capacity are not sufficient for complex modernization programs.
