Computer failure expert witnesses render expert opinions on allegedly “failed” computer systems, software and software projects. They should have the ability to educate triers of fact and counsel about IT industry standards and practices, especially regarding the technical abilities of the system (hardware, software, network, performance, functionality, scalability, portability, reliability, recovery, etc.) The best experts create understandable and straight-forward narratives that clarify and explain pertinent case facts and illuminate the root causes of failure, which oftentimes relate to: software selection configuration and customization; project & organizational risk management; GAP analyses; software & data engineering; testing/debugging; and readiness for go-live.
