When we mean to build, we first survey the plot, then draw the model, and we see the figure of the house. Then we must rate the cost of erection, which if do find outweighs ability. What do we then, but draw a new model in fewer offices, or at least detest to build at all?
- Bardolph, Henry IV, Part II, Act I
The goal of managing other people's money when build a product or providing a service is to plan and coordinate the needed work activities to deliver a satisfactory outcome, or complete enterprise endeavor within the constraints of schedule, budget, resources, infrastructure, and available technology.
The intellectual content of the discipline of engineering, business and technical management, risk management, and program controls, are oriented on the components and are value neutral.  Not matter the outcome the processes are the same or similar. The value produced by these efforts is independent of the means to produce them. Once delivered he consumer of this value cares little how they arrived. That consumer didn't buy the process to produce that value, they bought the value. When these are confused the notion of focusing on value is perverted to focused on those spending the money rather than on those providing the money.
The underlying principles of these disciplines are focused inside the boundaries of that system. The resulting value is focused outside the system of it production.
