As part of a system engineering team (Not software engineer), your services are needed to review a problem in an apartment. The apartment complex's owner has received quotes from three separate consulting vendors on how to fix the issue of the slow elevator. Per the recommendation from the consulting group, below are some facts associated with the problem.

The consultant report;

• referenced persistent complaints about the period of the wait time for the elevators.
• The apartment has three elevators for customers and one service elevator, specifcally for staff and emergency use.
• The speed of the elevators is fundamentally a function of the computer controller and motor assembly.
• 80 customer complaints about elevators in the last seven months.

Technical Data Report

• The average time to wait for a ride on the elevator is 40 seconds. However, the industry average wait time for similar operations is 30 seconds. These elevators are obviously underperforming with respect to the standard of the industry.
• Elevators were periodically maintained and inspected as needed.
• Service elevators are used exclusively by staff the customers barely use the service elevator.
• The service elevator is in bad condition to be used by the customers.
• The cost of fixing the issue related to the elevators delay will vary based on the degree to which the computer controller and motors are changed. The current equipment is ten years old with an expected useful system lifespan of thirty years.

The consultants report identified 4 alternatives to change the elevator system, each with unique performance levels and associated costs.

1. Place the Service Elevator into Use for Customers. Associated costs: $195,000. This will decrease the elevator wait period from 40 secs to 33 secs.
2. Upgrade the software for the controllers. Associated costs: $95,000. This will decrease the elevator wait period from 40 secs to 35 secs.
3. Upgrade the controllers and the motors. Associated costs: $480,000. This will decrease the elevator wait period from 40 secs to 26 secs
4. Substitute the entire elevator system. Associated costs: $4 M. Performance will decrease the elevator wait period from 40 secs to 21 secs.

Question:

1. Identify all the stakeholders
2. Construct a Stakeholder Analysis Matrix for the situation with at least 3 stakeholders.
3. Identify an appropriate response strategy for three of the stakeholders.
4. Based on the information presented, which option would you recommend as the best? Why? (Give a complete analysis and logic to support your recommendation)
5. What additional information would help in the analysis?
