Final answer:
Re-engineering involves the complete redesign of a process, it represents a significant change compared to the concept of kaizen, and it may involve high risks, making all three provided statements true.
Step-by-step explanation:
The student asked which statements about re-engineering are true. Re-engineering is indeed the complete redesign of a process to find new ways to achieve an objective, and it involves making substantial changes rather than small, incremental improvements like kaizen. Re-engineering does often represent a "giant leap" forward rather than small, continuous improvements. Additionally, because re-engineering can involve significant changes to established processes, there is a higher level of risk associated with it compared to incremental changes. Therefore, all three statements about re-engineering are true.
