Stepwise Project Management Methodology (PMM)

[xAsh]

Hi All, Hope you're well,

I've been given a hypothetical task, in software engineering, of project managing a team to create a website for a new university with a budget of 2 million and the website has to include many features.

I've got to discuss what methodology and lifecycle is appropriate for this project. I've deciced on spiral life cycle is approproaite but cannot find hardly anything on the stepwise methodology on the internet, can anyone point me in the right direction please and tell me if you agree this methodology is appropriate for a large, hypothetical project like this?

Thanks a lot guys
