Getting Ready to Modernize Legacy System

Many industries continue to rely on antiquated technology.

For instance, no one uses a pager to interact with friends or exchange information.

Nonetheless, many organizations continue to utilize them, owing to the difficulty of replacing the instruments that manage critical business activities across the industry.

COVID-19 also urged for a high priority on CIO agendas in several critical areas of digital enterprise transformation:

  • Using interactive chatbots to extend the reach of exceptional customer service,
  • Using automation to obtain better results in a shorter amount of time,
  • Legacy systems are being modernized, while redundant systems are being decommissioned.

In reaction to the disruptive force, many businesses have updated their digital technology, emphasizing "hey, it works" rather than "we've compiled the best features after investing years on this endeavor."

The pandemic has heightened the importance of this requirement. Many of these digital transformation trends are here to stay since businesses have expedited the adoption of many technologies by several years.

Here are some costing models to can refer:

  1. COCOMO or Constructive Cost Model, COCOMOA I estimates maintenance, while COCOMO II calculates migration, and reengineering efforts.
  2. FPA or Function Point Analysis is a technique for evaluating the functionality provided to a user by using functional requirements. These points are tallied and weighed in various project KPIs such as performance and quality.
  3. Putnam's model helps when you know the scale of the project, you can use this process to estimate the time and work required to complete it.

Before jumping to modernize legacy systems you need to analyze your current system and do a few framework checks to know where your IT infrastructure stands.

Technologies analysis:

The first stage is to identify and examine the present product's technology stack. As a result, we can determine whether the programming language or frameworks are still relevant and supported by the suppliers.

Architecture analysis:

It's vital to undertake an architecture audit analysis if the tech stack is still relevant or not for future purposes. It will assist you in identifying the system aspects that are working properly and focusing on the ones that require modernization.

Performance Evaluation: Its goal is to find out if there are any further difficulties with the legacy systems. Poor performance or major flaws can necessitate both a complete system reengineering and targeted improvements.

Review of the code and UI/UX:

Legacy software typically has a large codebase that necessitates frequent reviews and restructuring. The software has a tendency to "rot" if it is not properly maintained.

To determine which portions of the system interface require modification, a detailed design assessment is required.
