"Describes the purpose of forensic systems engineering: to identify dysfunctional processes and to determine root causes of process failure, and further, to assist the court in determining whether harm or a breach of contract has occurred"--

"Forensic Systems Analysis addresses relatively new developments in two professions: the law and engineering. The author covers the theory of process liability, management of operations, process liability and operations, analysis of dysfunctional processes, process risk analysis, and process/product verification and validation. He also discusses process stability, capability, and reliability. The narrative is addressed to both plaintiff and defendant and offers analyses that present novel uses of traditional engineering methods concerning risk and product quality and reliability. The presented methodologies and arguments are equally valid when applied to service industries. Managers, engineers, technicians, auditors, and diverse analysts benefit from thebook's rigorous approach to system tactics and constraints related to product and service operations"--

A systems-level approach to reducing liability through process improvement

Forensic Systems Analysis: Evaluating Operations by Discovery presents a systematic framework for uncovering and resolving problematic process failures. Carefully building the causal relationship from process to product, the discussion lays out in significant detail the appropriate and tactical approaches necessary to the pursuit of litigation with respect to corporate operations.

Systemic process failures are addressed by flipping process improvement models to study both improvement and failure, resulting in arguments and methodologies relevant to any product or service industry. Guidance on risk analysis of operations combines evaluation of process control, stability, capability, verification, validation, specification, product reliability, serial dependence, and more, providing a robust framework with which to target large-scale nonconforming products and services. 

Relevant to anyone involved in business, manufacturing, service, and control, this book:

  • Covers process liability and operations management from both engineering and legal perspectives
  • Offers analyses that present novel uses of traditional engineering methods concerning risk and product quality and reliability
  • Takes a rigorous approach to system tactics and constraints related to product and service operations and identifies dysfunctional processes
  • Offers both prescriptive and descriptive solutions to both the plaintiff and the defendant

The global economy has created an environment in which huge production volume, complex data bases, and multiple dispersed suppliers greatly challenge industrial operations. This informative guide provides a practical blueprint for uncovering problematic process failures.
