what are the risks for the two options?

You are leading a team of engineers who are developing a new water recycling system for a lunar orbiting spacecraft. This system will reduce the need for resupplying fresh water to the spacecraft, which saves tens of thousands of dollars in launch costs. The system operates by recovering latent moisture in the internal atmosphere as well as by recycling urine and gray water from crew usage. The system will also receive a small amount of make-up water from the carbon dioxide recovery system. A key component in the system, the control module for the phase separator, failed the radiation hardness test. A rapid analysis by your colleague in the testing department showed that the specific issue was with a set of surface mounted capacitors on three printed circuit boards (PCBs) in the control module. In discussing the problem with the vendor of the control module, it was determined that the problem could be resolved by replacing the surface mounted capacitors with embedded capacitance. This will require a complete redesign of the 3 PCBs, which is estimated to take 12 weeks, which includes redesign, manufacture of the PCBs, reinstallation into the control module, and re-delivery to your team. The change in design would result in a weight decrease of 5 ounces. The vendor estimates an additional cost of $85,800 to perform this work. Because the vendor met all of the requirements stated in the contract, the cost increase must come from your project budget. You had members of your team look into alternatives. The alternative is one of the other vendors that had bid unsuccessfully on this component during the original contract bid. This vendor has previously provided hardware which was used in other subsystems. This vendor has a rapid prototype delivery process, and could potentially deliver a prototype within 4 weeks of receiving the contract. If the prototype passes initial radiation testing, the final product, the flight unit, could be delivered 4 weeks later. The cost of delivery would be $106,500. However, this module is 0.75 inches longer, and 0.5 inches wider than the original vendor's design, and weighs an additional 1.2 pounds. Integrating this module into the existing phase separator module will require rework by your team, including modification of some existing hardware. Team members estimated the redesign would require 7 working days (2 team members full time), and modifications would require an additional 9 days (3 team members full time). However, design and mods could begin as soon as the prototype passes radiation testing, in parallel with manufacturing the flight unit. All of this effort is in addition to other scheduled work for your team, which is also in the critical path for delivery of the water recycling system. Once the control module is delivered, your team needs to perform bench testing (3 days). The component will then be sent to the testing team, which is in a different department, for radiation testing (5 days). However, the radiation testing lab is scheduled to undergo its required annual calibration/recertification 10 weeks (2.5 months) from today and will be unavailable for 9 working days. The calibration/recertification cannot be rescheduled; failure to obtain recertification on schedule will result in the testing lab being shut down. Regardless of which option is chosen, once radiation testing of the flight unit is successful, integration of the control module into the phase separator assembly is performed (6 days). The build-up of the rest of the subsystem will take your team an additional 7 weeks, which is followed by end to end testing (8 days). Your project is already near the cost limits; with 24 weeks to go before you are scheduled to deliver the entire water recycling system, your cost margin has shrunk to $100,305. In addition to the increased cost of the rework, you would also have labor costs associated with extra work for your team; there are 7 people on your team, not counting yourself. The water recovery system is currently 6 pounds, 6 ounces over its allocated weight limit; the Program Manager has given a temporary waiver for the additional weight, but has asked all subsystem leads to find weight savings. The Program Manager is aware that the water recovery system has suffered a component failure and has asked you and your team to give a presentation to him next week. The Program Manager is only marginally familiar with the architecture of the water recovery system. He is expecting you to provide an explanation of the issue. He is also expecting your team to analyze alternatives and provide a recommendation for a path forward, including rationale for the selected path and impacts to cost, schedule, and weight. You will require the Program Manager's approval for your selected alternative prior to proceeding with either option. The meeting will include the other Life Support subsystem managers, the lead business analyst, lead contracting manager, the testing department manager and her test team lead for the radiation testing and analysis.
