At  the European Weather Centre, we are looking very closely
at the "spiral" model proposed by Barry Boehm as an alternative
to the traditional "waterfall" approach. 

The software project under development involves data base
management and visualisation of LARGE amounts of data, 
generated on a CRAY Y-MP and displayed at workstattions.

It appears that the "spiral" model is better suited to such environments
than the "waterfall". Has anyone has experince on it ?

BTW, the basic reference we're using is:

"A Spiral Model of Software Development and Enhancement",
Barry Boehm, IEEE Computer, May 1988.
