You are developing a dental wire-bending machine compatible with the three most popular dental wires, covering 90% of the market. During certification testing, one wire manufacturer announces a new incompatible wire, reducing expected market coverage by 25% from the initial 90%. What should the project manager do?

The correct answer is to investigate the impact with the team and survey the market. This is a proactive and analytical approach. The project manager needs to understand the full scope of the problem (impact on market coverage, project objectives, and potential revenue) before deciding on a solution. Surveying the market for alternative wires is a practical step to mitigate the risk and explore new opportunities. Meeting with sales and marketing to persuade the manufacturer is unlikely to be effective and is outside the project manager's direct control. Meeting with the wire manufacturer to secure existing stock is a short-term fix that doesn't address the long-term market coverage issue. Stopping the project and starting a new one is a drastic measure without first understanding the full impact and exploring alternatives.
