You are the project manager for a large health information technology project. You are confronted with an important decision on your project: How much posttesting of the design is appropriate for this project? Employ decision tree analysis to provide senior management with the best course of action for this decision.
For this decision, you have three possible choices: no posttesting of the design, moderate posttesting of the design, or full posttesting of the design. No posttesting will incur no additional costs due to testing and has a 25% chance of a successful implementation. If it is unsuccessful, rework costs are likely to be $30 million dollars. Moderate testing will cost $5 million and has a 50% chance of success. If it is unsuccessful, rework costs are likely to be $30 million. Full testing will cost $10 million and has a 75% chance of success. If it is unsuccessful, rework costs are likely to be $30 million. Which solution is appropriate for this project?
