Usually the benefits of early returns far exceed the penalty of additional costs.
True, but the case may arise where you might not have enough cash to invest even though you are convinced that incremental delivery is the way to go.
Because the returns are time sensitive, the net present value of an MMF varies according to where in the development sequence it is developed/delivered.

However, one of the benefits of incremental development is that it generally requires less upfront cash than a non-incremental approach. The reason being that you only have to fund part of the project and then revenue from early deliverables start to kick-in to offset costs.

In my planification (real past case!!), I have identified two MMFs which needed approximately there months to complete. They could more or less be done in parallel but this isn't an option since I had only one developer working for me and I couldn't allow myself to hire another one. So, I have decided to develop one MMF and then the other one. Obviously, I chose the one MMF whose ROI was bigger, makes sense. The problem is that my budget was so tight that I couldn't even start the work on this first MMF unless I had found other financial solutions.

A great point! Identifying MMFs is both a science and an art. We've included a whole chapter in book on this subject. In addition to being Marketable, and a Feature, it also has to be Minimum
I miss the old days when I would think up a sinister scheme for world domination and you would show a little emotional support. So just look at this tiny ad:
