How AI can support maintenance of aging government systems

July 21, 2021

Phase Change President Steve Brothers recently authored a contributed article for Nextgov.com about how artificial intelligence (AI) tools can help governments deal with the mainframe-developers skills shortage and continue to maintain critical legacy systems.

The article, How AI Can Help with Critical Government System Maintenance Needs, describes how we should change the current industry strategy of solving the skills crisis by simply increasing the number of programmers with legacy language skills.

Brothers' article explains why the problem isn't just language skills, it's the lack of application knowledge to productively maintain applications. Supporting applications is very different than creating them. Defects are discovered through behaviors, which the developer must trace back to the flawed source code. The defective code and its dependencies can be spread throughout the codebase in multiple modules and repositories. Without the application knowledge to know how the system works, maintenance becomes an unproductive scavenger hunt. Then the developer must discover how the repair will impact the rest of the system.

AI tools help developers locate and isolate defective code by conceptualizing code computations at machine speed. It eliminates code unrelated to the bad behavior and enables the developer to find and focus on defects. Then the AI simulates running the repaired code to determine change impact so the developer is confident his work won't negatively affect the application.

IEEE conference accepts paper co-authored by Phase Change scientists

July 20, 2021

The International Conference on Software Maintenance and Evolution (ICSME) 2021 accepted a technical paper authored by current and former Phase Change research scientists for presentation at its 37th annual event in Luxembourg City, Great Duchy of Luxembourg, September 27 - October 1.

The paper, "Contemporary COBOL: Developers' Perspectives on Defects and Defect Location," was co-authored by current Phase Change Senior Research Scientist Rahul Pandita, former Senior Research Scientist Aleksander Chakarov, and former intern Agnieszka Ciborowska.

The authors' goal is to direct the attention of researchers and practitioners towards investigating and addressing challenges associated with mainframe software development. More specifically, they present results from surveys of COBOL and more modern programming languages regarding defects and defect-location strategies. Software development has made substantial advances in software maintenance for modern programming languages but mainframe programming languages receive limited attention.

Meanwhile, mainframe systems are facing a critical shortage of experienced developers as the current generation retires. Without extensive mainframe and application-specific experience, replacement developers face significant difficulties, even during routine maintenance tasks such as code comprehension and defect location.

ICSME is an annual event sponsored by the Institute of Electrical and Electronics Engineers (IEEE) to present, discuss, and debate the most recent ideas, experiences, and challenges in software maintenance and evolution. This year's conference will be a virtual event.

AI rises to the challenge with COBOL

A May 28 article published by TechRadar pro, and written by Phase Change President Steve Brothers, explains how the well-reported "COBOL skills shortage" is not really a fundamental problem for enterprises that rely on mainframe systems. The real challenge is application knowledge. Developers can learn COBOL in less than 6 months. What they can't learn quickly is specific application knowledge because that knowledge comes from experience.

Steve also describes how AI tools that assist developers in identifying and locating code responsible for specific behavior will help them reveal the application's intent and expose code that requires change. The developers will learn the application through task completion while remaining productive for the organization.

Education is vital to legacy applications’ future – podcast

May 21, 2020

Educating young developers about the importance of legacy software applications, and building the tools needed to connect them with modern technologies are the keys to combining old-school reliability and new-school engineering say Bill and Eileen Hinshaw of COBOL Cowboys.

If you've followed the stories about the computer-system meltdowns brought about by the overwhelming demand for government financial assistance during the COVID-19 pandemic, then you've probably read about COBOL Cowboys.

The Hinshaw's founded the company to bring together experienced programmers and organizations that lack the expertise needed to fix and maintain their legacy applications.

When the system failures started, government officials were quick to blame their back-end mainframe applications, just as they did during the Y2K crisis. However, those same officials were forced to backtrack when Bill and others revealed that the mainframe applications were fine – it was the agency's infrastructure and front-end systems that caused the problems.

Bill and Eileen have done a number of interviews about the system failures, but now they want to talk about moving forward to ensure that these legacy systems are updated using modern technologies, so they don't get blamed for the next computer catastrophe.

That's where education and better tools come into play. Bill and Eileen say the good that's come from our current situation has been the increased public and industry awareness of how important legacy systems are to industries and companies around the world.

Their goal is to educate young software developers on the advantages of mainframe systems so more programmers will be interested in working with them and will replenish the declining workforce.

Learn more about the COBOL Cowboys and how critical mainframe applications are to the world in this Phase Change podcast.
