Is it Manufacturing or Projects?
Definitions I am using for these:
Project
Planned set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations.
and
Manufacturing
The process of converting raw materials, components, or parts into finished goods that meet a customer's expectations or specifications. Manufacturing commonly employs a man-machine setup with division of labor in a large scale production.
I can suggest that in software development manufacturing translates to:
"raw materials" = requirements and specifications
"parts" = software libraries
"finished goods" = service/software deployed and serving customers
"man-machine setup" = configuration of environments
"division of labor" = dev and ops and qa, etc...
"large scale production" = lots and lots and lots of code
When I write "Software Development" I actually mean the whole cycle that includes lead-time from the point where some customer need is discovered, to the point of customer value created and delivered.
