Which of the activities can be considered value-enabling and based on your answer, what is the percent value-enabling time in this process? 20 points) 5. What is the takt time? (10 points) 6. If demand increased to 120,000 patients annually, what is the takt time? (10 points) 7. What would you do in the second situation (referenced in part 6)? (10 points) 8. Discuss your results and comment on the hospital's ability to handle the demand. (0 points)
