You are asked to initiate a project that the company has been trying to launch for almost a year, without success. The Marketing Department believes that customers would love the product because it's highly innovative and nothing like this exists on the market, while the R&D Department believes the new product idea has not been well thought out, and the IT Department says the technology behind this product is untested and therefore too risky.

What would be the mest development methodology for this project, and why?

Justify your answer.
