Out with the Old - Here’s How Legacy Systems Can Enter the Market Again

Everyone wants their legacy systems modernized

Legacy system modernization is a shared focus for IT professionals everywhere, and CIOs are on the lookout for a simple fix to address the challenge.

The question is – what drives this need for IT legacy modernization?

Legacy architectures are expensive and difficult to maintain and may pose business risks.
The biggest reasons why companies go for legacy modernization are:

  1. High cost of sustaining legacy applications and the infrastructure in the long run
  2. Shortage of skilled employees in companies still using legacy systems – lack of proficiency in legacy languages like Common Business Oriented Language (COBOL) and Natural
  3. Workers look forward to on-the-job technologies being on par with—or even better than—what they have
  4. Most importantly, people today are more tech-savvy and connected than ever before. Customers expect businesses to be online, easily accessible, and ready to meet their needs in a snap with modern and up-to-date UI/UX standards

All of this calls for legacy modernization

Business owners often resist legacy system modernization due to high costs and fear of change. Although these programs still work, they can cause security problems, prevent scaling, and make it challenging to provide advanced customer functionality. Southwest Airlines is one such example. In 2022, Southwest Airlines canceled over 13000 flights due to its outdated systems and IT infrastructure. Netflix, on the other hand, is a market leader in online streaming due to its pioneering modernized microservices architecture.

Thinking legacy system modernization is basically asking the right questions

  1. Are there opportunities to automate everyday tasks for better speed and accuracy in the operations?
  2. How can data analytics be used to gain deeper insights into business operations, customer behavior, and market trends?
  3. Where are transactions being made difficult for customers or letting them down?
  4. What can be done for customers and employees to make more delightful and successful experiences?
  5. How can technology be used to optimize inventory management, reduce waste, and ensure ideal stock levels?
  6. How can employees be empowered to serve customers better or do their jobs better?

Starting from scratch sounds scary

Starting from scratch is not a feasible option for many organizations in the short term. Replacing legacy systems all at once can lead to high costs, complexity, and disruption for businesses.

Fortunately, delivering new customer experiences and greater automation does not always require a do-over.

Many companies still using legacy systems are now seeking to move forward with digital transformation by integrating new digital technologies on top of legacy systems via APIs to innovate new services, experiences, and process automation. Smart work wins!

Legacy modernizing 340PriceGuide – a Genetech project

When 340B PriceGuide, a major healthcare player, needed a tech boost, they turned to Genetech. Their legacy system had some quirks—basic drug searches, missing formularies, manual data chaos, and a mobile app that went MIA offline.

Genetech took on this challenge and worked the way bottom up. First phase included modernizing the drug search functionality with advanced options, integration of formularies, segmentation of patient groups, and creating a dedicated company section. In the second phase, Genetech decided to give the 340B PriceGuide company users access to an admin portal. This worked wonders! Now, the users could do away with the admin dependency and had the option to tailor configurations independently.

The outcome was splendid! Sales and user registrations soared from 400 to 1000, and there were 15 to 20 new hospital partnerships. On the operational side, the digitization efforts led to enhanced efficiency, productivity, and cost savings. The offline functionality in the mobile app addressed a crucial pain point for doctors without constant internet access.

This case is an excellent example of how legacy modernization is not just a need but a catalyst for significant business growth.

For Genetech, the focus is on smart digital transformations for legacy systems that are not just necessary but imperative for long-term success.
