Challenges of enterprise software modernization A recent study by vFunction and Opticca revealed that modernization projects fail, particularly in the case of enterprise-wide initiatives. 4 out of 5 Here are some common challenges that enterprises typically encounter with legacy application modernization and practical tips for addressing them. Isolated organizational structures and bureaucratic complexities In complex organizational setups characterized by bureaucracy and decision-making complexities, enterprises face challenges in achieving unified strategies and aligning stakeholders' perspectives for system modernization. How to solve this issue? Encourage close collaboration between architects and executives to craft a practical implementation roadmap that aligns with the scope of the upcoming modernization project while considering the realistic tech perspective. When assessing the current state of a legacy system, prioritize immediate attention to key issues. This establishes a robust foundation for future changes and promotes more efficient and timely decision-making. Operational silos Operational biases often arise due to organizational silos, creating a disconnection between enterprise decision-makers and day-to-day operations. This disconnection can lead to a limited understanding of lower-level processes and the necessary modernization efforts. Consequently, implemented business and technical solutions may lack a practical perspective, resulting in operational inefficiencies and budgetary waste. How to solve this issue? While maintaining a balance between the viewpoints of architects and executives, it's crucial to prioritize the perspective of software system users. Recognizing that the efficiency of implemented tools depends heavily on end-users, leaders should invest time in understanding their issues. Initiating discovery and gaining insights into users' daily routines can help reduce operational biases and lead to better modernization outcomes. workshops Technical debt Significant technical debt is a common outcome as enterprises undergo technological evolution. The process of modernization often involves multiple implementations and adjustments to existing systems, resulting in increased engineering complexity. How to solve this issue? When concerns arise about the dependencies among components within an enterprise system and the feasibility of modernization is questioned, building a new system from scratch is a more practical option. In this case, enterprises should dedicate effort to identify potential technical risks and establish a robust backup plan to ensure operational continuity during the modernization process. Planning enterprise software modernization A successful approach to legacy application modernization involves aligning engineering, business, and user perspectives. The below steps will help you ensure every aspect is actually considered. Step 1. Evaluate the system Typically, the decision to modernize is driven by specific challenges in the technology, architecture, or functionality of a legacy application. To confirm that modernization is the most suitable solution for these challenges, enterprises should assess their systems based on these drivers: Business fit Business value System agility Cost Complexity Risks Considering both business and IT perspectives, these factors help executives determine if a legacy app lacks in meeting business needs. For example, if the ownership costs are excessive, the technology is overly complex, or there are compromises on security aspects, then modernization is a must. Step 2. Learn the UX context Look at the current experiences offered by software systems to assess their dependencies and find UX inconsistencies that may impact overall efficiency and satisfaction. Conduct workshops for knowledge-sharing, encourage employees to provide feedback, review past changes, and assess the practical usefulness of solutions implemented to address user issues. Explore other applications used by employees in their daily tasks to understand the patterns they are accustomed to and comfortable with. Understand the causes behind the existing UX challenges to avoid similar challenges and risks in future redesigns. Step 3. Evaluate modernization As companies get started with modernization, they usually have to choose from various methods. utilizing and extending application features by encapsulating data and functions, presenting them as services through an API. Encapsulation: transferring the application components to alternative infrastructure (physical, virtual, or cloud) without modifying its code, features, or functions. Rehosting: migrating to a new runtime platform with minimal changes to the code while preserving its structure, features, and functions. Replatformation: restructuring and optimizing existing code (without altering its external behavior) to eliminate technical debt and enhance nonfunctional attributes. Refactoring: substantially modifying the code, shifting it to a new application architecture, leveraging new and improved capabilities. Rearchitecture: redesigning or rewriting the application component from scratch while preserving its scope and specifications. Rebuilding: eliminating the former application component entirely and replacing it, considering new requirements and needs simultaneously. Replacement: Step 4. Think of the future Make sure that the updated solution proves practical in real-world scenarios. Here are some practical tips for maximizing the value of modernized software systems: This facilitates efficient maintenance and agility in keeping the systems operational in the future. Ensure any modifications are documented. This allows engineers to detect technical issues early and solve them before they begin to impact enterprise productivity and jeopardize business outcomes. Establish 24/7 technical support for modernized systems. Implement and assign a dedicated support team responsible for addressing any questions and creating comprehensive guides on using the updated systems. Invest time in onboarding employees to the changes. corporate training Help employees understand that their input matters, valuing the opinions and feelings of each team member. Foster a sense of ownership among teams using modernized systems. How to make legacy application modernization successful? Like any digital project, legacy application modernization requires primarily developing a thorough technical strategy specifically for business requirements and modernization context. At the same time, my years of experience in contributing to modernization projects for enterprises have shown that often the key to success is not only about making reasonable technical decisions but also about bringing consistency to the changes implemented.
