A brief case study of Lockheed Martin’s use of Understand™ in its software maintenance process.

“Understand™ is good for discovering the structure of the code dependencies and call-paths... it would have taken me hours to generate the same thing on my own, and I would not have had near as much confidence in my own work (assurance that I understood the code correctly).”

— Paul Hyland, Software Engineer, Lockheed Martin

Customer Overview

Lockheed Martin develops some of the most advanced flight hardware and software in the world and must often maintain those projects for several decades. The sheer size of the source code and the use of old and less-common coding languages (Fortran, Ada, etc) makes analysis and maintenance a major undertaking for the developers involved.

Project Brief

To determine the structure of a complex legacy Ada program.

Implementation of Understand™

Understand™ was used for the following applications:

  • visualize the Ada source code structure

  • locate and view call dependencies within the code

Project Outcome

The project was completed successfully and Understand™ helped the developer to rapidly produce an intuitive structure of the source code. It saved several hours of analysis time and provided an accurate understanding of the complex legacy project.
