@fansy,
Quote:it normally follows the rolling pattern of “deploying-developing-designing”.
'rolling pattern' is not idiomatic for English as far as I know, Fansy, so it sounds a mite strange to me.
And from the available context, it seems like this does not follow the normal "put forth a model first, and put it to application, then you make an improved model and put it to application again". Rather there is deployment, then development, then design.
