As any software becomes outdated over time, every company inevitably faces the need for application modernization to improve the functionality, performance, security, or maintainability of its legacy systems. However, not all modernization initiatives succeed, with many failing to anticipate expected value or falling short of business objectives.
A high failure rate can be largely attributed to strategic, organizational, and technical shortcomings during the planning and execution stages. Understanding these common pitfalls in advance can help organizations avoid them and maximize the chances of project success.
In this article, experts from Itransition, a company providing application modernization services, highlight the most common pitfalls of app modernization and provide practical recommendations to help organizations mitigate risks and achieve better outcomes.
No clearly defined success metrics
One of the most common reasons why app modernization initiatives fall short is the absence of clearly defined and measurable success metrics. Without well-defined KPIs at the project start, companies may struggle to translate their high-level business goals into specific, actionable targets. As a result, technical teams lack clarity about what is expected of their work, which can lead to misguided architectural decisions, redundant functionality, and ultimately reduced app modernization ROI.
Recommendations:
- Start by defining and prioritizing your high-value business goals, whether it is reducing app maintenance costs, enhancing user experience, or improving an app’s security posture.
- Then, map your strategic business objectives to measurable KPIs, such as the total cost of ownership, system usability score, or vulnerability density.
- Use the initial kickoff to inform the technical team about KPIs, explain how KPIs relate to broader modernization goals, and clarify how the team’s technical tasks contribute to business outcomes.
- Implement KPI monitoring and reporting tools to systematically evaluate your tech team’s performance against success metrics and ensure that the team remains on track to achieve them.
No change management strategy in place
Application modernization driving digital transformation can cause disruptions in the established workflows and user habits. Modernization projects involving upgrades to user-facing functionalities and improving user interfaces are no exception. If not properly managed, these disruptions can hinder workplace productivity, delay value realization, and severely undermine the overall project ROI.
For instance, even seemingly minor UI redesign changes, such as color schema changes or relocation of buttons and menus, can slow down navigation for experienced users, who have operated a legacy app for years. As a result, even routine tasks can cause cognitive overload and become more challenging to perform, so until users get accustomed to the new design, they can experience frustration and productivity dips.
App modernization projects that involve introducing completely new app features can also disrupt organizational workflows. Even if business users already possess skills that are required to master new functionalities, they may still need some time to adapt to different ways of performing tasks, which can cause change fatigue and productivity drops.
Practice shows that user adoption issues in app modernization projects commonly stem from poor change management and insufficient preparation of end-users for digital workplace transformation. Building and implementing a people-centric change management strategy is therefore essential for application modernization success.
Recommendations:
- Identify and document which work processes and company departments will be affected by modernization. Also, evaluate and document potential impacts on specific user roles.
- Conduct surveys, focus groups, and interviews to assess the readiness for the transformation among business users (ask them if they know what is changing and why, how they feel about the change, if they have the skills to use a modernized app, etc.).
- Analyze the assessment findings to outline what users are lacking to successfully adapt to the change (i.e, motivation, confidence, skills). Based on users’ specific needs, build a tailored change management strategy encompassing actionable communication, training, and support plans.
- After the app rollout, continuously monitor end-user behavior and performance, as well as capture their feedback, to measure app adoption success. If needed, refine the change management strategy based on the obtained insights.
Poorly managed technical debt
Legacy applications inevitably accumulate technical debt, examples of which include outdated frameworks, convoluted business logic, and excessive custom code. Not only does technical debt make legacy software harder to maintain, but it also makes software more difficult to modify, as even minor changes can trigger unintended consequences across the system. If left unaddressed, technical debt can significantly undermine modernization efforts. To mitigate these risks, companies should proactively and systematically manage them from the very start of their projects.
Recommendations:
- Before making any changes to a legacy app, map the existing technical debt, classify it based on impact, and create a detailed register for technical debt to create a single source of truth for your tech team.
- Instead of a risky “big bang” modernization strategy, adopt incremental modernization approaches (the strangler fig pattern, parallel implementation, etc.), as they allow teams to modernize legacy apps gradually by making small, iterative improvements, which are easier to test and roll back.
- Incorporate relevant technical debt remediation tasks into the app modernization roadmap to continuously minimize technical debt, reduce its potential negative impact, and make future improvements less risky.
Final thoughts
Application modernization projects are widely recognized as challenging and risky initiatives that, if not managed properly, frequently fail to deliver the expected return on investment. Understanding and preventing common pitfalls is critical for success, and this article can help you in this regard.
