The big difference between business process reengineering and continuous improvement programs like TQM or Six Sigma is that:
1. business process reengineering aims at creating altogether new best practices whereas TQM and Six Sigma are used to make gradual improvements in existing best practices.
2. reengineering aims at remodeling and updating particular value chain activities to achieve dramatic gains in product quality whereas TQM and Six Sigma are best used for achieving small, but ongoing, reductions in operating costs.
3. business process reengineering is a tool for achieving one-time quantum improvement whereas TQM and Six Sigma programs aim at ongoing incremental improvements.
4. reengineering helps create core competencies whereas TQM/Six Sigma are tools for making a core competence stronger and more efficient.
5. reengineering is a tool for revamping entire company value chains whereas TQM/Six Sigma concern instituting defect-free production methods and delivering world-class customer service.

Adog whistle manufacturer's factory was located near a residential area. the manufacturer used the most effective methods for testing its whistles, but it was impossible to completely soundproof the testing area. a breeder of champion show dogs bought some property near the factory and raised and trained her dogs there. although the whistles were too high-pitched to be perceived by human ears, they could be heard by the breeder's dogs. consequently, the dogs often were in a constant state of agitation. in a suit by the breeder against the manufacturer, what is the likely outcome? response - correct a the breeder will prevail on a trespass theory, because the sound waves are entering onto the breeder's property. b the breeder will prevail on a nuisance theory, because the sound of the whistles is a substantial interference with the breeder's use of her land. c the breeder will not prevail, because the sound of the whistles is not a substantial interference with the breeder's use of her land. d the breeder will not prevail, because the manufacturer has acted reasonably in testing its whistles.
