What’s UI/UX Modernization?

When it comes to UI/UX modernization, it’s a process to improve the UI (user interface) and UX (user experience) of a website or an application. The process consists of updating the look and feel of the software intended to enhance the navigation and optimize the content. Furthermore, UI/UX designing of a system is aimed at making software way more intuitive, responsive, and interactive.

UI/UX application modernization tends to be used to make the system attractive and accessible to the users who intend to use and navigate it. Modernizing the UI/UX of an application and software allows enterprises to improve user experience and customer satisfaction, accelerate sales, and strengthen overall revenue.

When it comes to examples, there are many examples of UI UX design, including Uber’s shift to SOA, Airbnb’s effort to organize principles to redesign the UX, and how Netflix innovated the web player experience by conducting modernization. You, too, can experience the equal result by conducting UI/UX modernization.

Needs & Benefits of UI UX Modernization

Ensuring a better user experience needs to fill the gap between expected products and the products you deliver. This gap is created by both design and tech debt. Whereas design debt can occur because of inefficiencies in designing, for tech debt, there can be various reasons. To mitigate these hassles, an organization should consider UI/UX modernization that’s more likely to mitigate tech as well as design debt, improving customer experience.

Apart from that, there are various aspects, for instance, changes in customer demand, the constant evolution of design trends, and the like, making the modernization of the UI and UX design of an application even more crucial. Have a sneak peek at the pointers given below to know the significance and benefits of UI UX Modernization!

  • Continuously Changing Demand— Just because advanced technologies provide next-level services and value beyond expectations, the customer’s demand tends to evolve consistently. Customers look for hyper-personalization, and organizations could leverage application modernization to deliver a highly customized, more personalized experience.
  • Scalability to The Cloud— Now, most of us are dependent on online solutions for most of our day-to-day activities. As a result, the requirement for uninterrupted accessibility has gone higher than ever. It’s one of the causes why cloud integration is essential for Businesses. Employing innovative cloud technology enables seamless UI/UX upgrades as well as bug fixes along with delivering cost optimization based on requirements.
  • Increasing Security Vulnerability— Modernizing software and UI design assist you in improving data security. Besides incorporating security features, tools, and monitoring systems, the software and UI design architecture can help strengthen data security. UI/UX modernization allows companies to own a system that ensures compatibility with security integrations.
  • End-User’s Satisfaction— Around 45% of online customers share negative experiences that are not right for businesses. Modernizing the UI/UX design and making sure the process is user-centric, sites are mobile-friendly, and information is valuable, relevant, and convenient to find tends to improve the customer satisfaction level.
  • Maximized Revenue— A report from Forbes, from Forrester (paid report) states that, on average, each $1 that’s invested in UI/UX design tends to generate $100. In contrast, around 44% of CIOs have an opinion that organizational growth is reducing while using legacy software. Among applications competing for the same customers, the one embedded with a modern UI/UX offers a competitive edge.

UI/UX Modernization Challenges

challenges-associated-with-UI-UX-Modernization

UI/UX modernization is essential; however, there are some challenges as well that you may encounter while conducting the modernization procedure. Let’s become aware of those challenges that may come your way in UX design and UI design!

Costly UI/UX Modernization

A variety of procedures are involved in rearchitecting and redesigning user interfaces. To conduct it appropriately, you may need to expand your team or, in some circumstances, need to hire experts to ensure accurate implementation of procedures. You may need to invest in some additional tools and technologies as well. Besides, there are development and development costs that you have to bear.

The cost to modernize a legacy system tends to vary depending on various factors, including the features you want and the complexity you have with your project. The cost can be anywhere between $15,000 to $75,000 and even more than that, depending on the different cost differentiators. These cost variables may be your target audience, the type of features you require, and needed upgrades like system, design, architecture, and the like.

Technical Debt

Tech debt is a collection of multiple short-term solutions as well as make-do models that have been outdated with time. That’s something that makes modernization crucial as well as challenging. Conducting the procedure tends to take more effort and time if your legacy system is large and has immense technical debt.

In order to get rid of technical debt, you need to analyze the entire existing system. At times, you may need to separate the system into various smaller chunks. In case the existing application gets deployed on an immense scale, separating it into multiple smaller pieces is more likely to mean disruption and crashes. Furthermore, you may need to encounter compatibility issues when new technologies are about to be used with the existing components.

Need For Continuous Monitoring

UI/UX modernization is a process full of complexities that consists of a wide number of tasks. Companies are required to have an efficient monitoring system to keep an eye on the progress of the procedure consistently. That’s something that lengthens the time of discovery phase in which organizations tend to identify major areas in UI for modernization. You need pre-defined metrics like the following to identify significant areas in UI/UX for modernization.

  • Task completion rate quantifies the time it takes a user to accomplish a task. The fewer time completion rates gesture, the better the user experience.
  • Error rate assists you in gauging the counts of user error entries. You’re capable of calculating errors simply by dividing the number of errors by all failed attempts.
  • Task success rate lets you measure the count of tasks a user can accomplish out of the requests made by them, in percentage. It enables you to check how conveniently users are able to complete the tasks on UI.
  • For perceived performance, page loading speed is essential. Users are more likely to consider your website or application’s quality based on its loading speed.
  • It’s essential to understand gaps in the UX to define and monitor the metrics. You can identify the bottlenecks and their sources based on the gaps and modernize those to improve performance.

Inefficient Processes

The streamlined procedure is one of the must-haves when it comes to UI/UX modernization. In case you have inefficient procedures in your organization, modernization tends to be slower. The existing legacy application in your firm is likely to have dependencies that can influence the new UI/UX architecture.

Therefore, you need to work with an accelerated procedure that’s competent in not only identifying dependencies but also mitigating them and ensuring an error-free migration to a new UI/UX architecture. Elements in the legacy application are likely to impact the UI/UX modernization procedure.

Misaligned Efforts

One of the challenges associated with UI/UX modernization is the misaligned efforts of the teams working on the project at various stages. A crystal-clear and shared understanding of what the UX is going to look like post-modernization should be clearly conveyed across various departments. Whether it’s the IT department, backend team, design team, or quality analysts, to get a quality outcome, everyone needs to be on the same page.

In order to mitigate misaligned efforts on the UI/UX application modernization project, collaboration is the key. Better and improved team collaboration and communication are more likely to help you ensure aligned efforts and mitigated time to market for a new project.

UI/UX Modernization Best Practices

best-practices-for-UI-UX-application-modernization

Now that we’ve discussed the needs & benefits, and challenges, it’s time to dig deeper and know the best practices for UI UX modernization. Some of the best practices that you can employ to modernize the UI/UX of your application are design thinking, re-architecting front-end, selecting the right technology, revamping the design, and the like. Let’s measure them one by one.

Implement Design Thinking

The first in the list of the best practices for UI/UX modernization is design thinking. It’s an iterative procedure where each of the members of a team understands the requirements & challenges to identify UI/UX gaps and then create appropriate solutions, execute prototyping, and conduct design testing. Businesses can make use of design thinking to create a user experience that is competent enough to troubleshoot the audience’s problems. That’s what enhances conversion rates.

The implementation of design thinking consists of the following:

  • Empathize— This includes pinpointing the pain points of your users interacting with your application through detailed research.
  • Define UX Gaps— Conduct intensive analysis of the critical data and gather them during the research phase, then define the gaps in the UX.
  • Ideate— Brainstorm the design ideas and venture to fill the UX gaps.
  • Creation Of A Prototype— Prototype based on your data analysis.
  • Test Your Design— Conduct A/B testing so that you can understand which prototype is capable of filling UX gaps.

Choose Right Technology

Organizations tend to make mistakes when it comes to choosing technologies. They often end up employing a technology that’s not suitable to their project’s specific needs. Furthermore, they include unstable technology stacks that are more likely to hamper their UI/UX performance in the future. Hence, you should focus more on choosing the technology that’s competent to align with your goals and can assist you in creating an excellent front-end for your application.

For instance, if you conduct a complete migration from monolithic to microservices, it requires you to deliver value depending on the goals you’ve set. Choosing a tech stack based on trends and economics is less likely to fulfill your business goals of providing value to the end users.

Consider Re-Architecting Front-end

Legacy architecture with tech debt tends to make UI/UX modernization challenging. Hence, re-architecting the front end is an approach that goes with application modernization. For instance, if you’re conducting a modernization of an app’s backend to microservices, you’ll be able to transform the monolithic front-end to a micro front-end.

Re-architecting an application consists of extracting the legacy code and analyzing it to re-construct it in a way that improves the performance and productivity of the whole team working on a project.

Improve UI/UX Testing

UI/UX modernization requires multiple tests, including usability testing, surveys, and the like. Selecting appropriate tests, monitoring the results, and integrating them into the interaction program are some of the prerequisites needed for an effective UI/UX modernization procedure. However, it’s essential to conduct the entire application UI/UX testing, which can be challenging, time-consuming, and costly. Don’t forget to consider updating the UI for all the legacy systems when you’re planning for regression testing.
