Book excerpt: Contract and procurement fraud, collusion, and corruption are worldwide problems. Such wrongdoing causes federal, state, and local governments, as well as private-sector corporations and businesses, to lose funds and profits, while the wrongdoers unjustly benefit. Bid riggers conspire to eliminate fair and open competition and unjustly increase prices, allowing some to monopolize industries. Too often, contracting officials and others responsible for placing orders or awarding contracts compromise their integrity and eliminate fair and open competition to favor vendors offering bribes or gifts. This results in unfair playing fields for vendors and causes financial losses for businesses, government agencies, and taxpayers. Charles Piper’s Contract and Procurement Fraud and Corruption Investigation Guidebook educates readers on fraud and corruption schemes that occur before, during, and after contracts are awarded. This book teaches not only how to identify such wrongdoing, but also how to investigate it and prevent reoccurrence. Piper shares the Piper Method of Conducting Thorough and Complete Investigations, his innovative and proven method of investigating contract and procurement fraud, and demonstrates its principles with personal, on-the-job examples (which he calls "War Stories") woven throughout the text. Intended for criminal justice students, as well as investigators, auditors, examiners, business owners, policy-makers, and other professionals potentially affected by fraud, this book is a must-read guide to effective procurement and contract fraud investigations from inception to testimony.
