A team at Bradley Park Hospital is involved in a process improvement project involving six major activities. Because the improvement is viewed as essential to obtain reaccreditation by The Joint Commission, it must be completed before the audit, that is, in 19 weeks. Data on costs and times have been gathered by the team. Crash the project using (a) the marginal cost analysis method, and (b) the LP method. What is the extra cost incurred?
