When an application crashes or is not working correctly, productivity is impacted the organization incurs additional costs to resolve the issue. This was common when application programmers released the application into production and let the users test it, identifying errors or bugs that needed to be addressed. This process was inefficient and unproductive. Now code is developed, tested, and verified before it is released. Application developers continue to provide updates, patches, and bug fixes, but these generally address user requirements, performance improvements, or any known bugs.

William Swansen

"Once an application I develop is released, it rarely crashes. This is due to the advanced application development tools I use, the software testing, and my application development methodologies. Once I write a block of code, I review it and run it through several tests to ensure the software is robust and able to function in extreme circumstances. I use advanced programming tools to discover relationships and dependencies between different blocks of code and confirm that they are working. I also employ Agile methodologies during the development process to identify any programming errors early so that they can be addressed."
