Assume you wish to chart out an action plan for a project to develop a full autonomous self-driving car. There is a large degree of uncertainty with several possible points of failure. The best approach is to: a) Use a Cause-and-effect diagram to chart out the possible sources of problems b) Consult a design engineer to help develop a Pareto diagram to determine where 80% of the failures are likely to occur c) Use a control chart d) Use a process decision program chart e) Both a) and c) Just the answer no need for explaning
