Developers are loath to tell management something can be
done unless they are certain of their own ability to do it. Domatic??™s experts
thus also raised a number of concerns that the proof of concept had not been able
to answer:
. Coding such simple applications was not challenging for average developers
. Uncertainty about 100% code generation
. Uncertainty about backward compatibility with existing code
. Are code generator facilities ?¬‚exible enough?
These are indeed often concerns after a proof of concept: even in the best case, in two
days it is simply not possible to prove these beyond doubt. Normally, however,
suf?¬?cient progress has been made that the experts feel these have been demonstrated
as well as could be in the limited domain, and certainly beyond what they themselves
had expected.
The extra two hours of work after the workshop are obviously not re?¬‚ected in this
bullet list from the presentation. This is unfortunate, as those two hours addressed
three of the main concerns. First, the refactoring of the modeling language allowed the
creation of more complex applications. Second, ?¬?nishing off the code generator
proved its ability to generate 100% code. Finally, these extra parts of the generator
required some of the more powerful features of the generator facilities, demonstrating
?¬‚exibility that had not been needed in the earlier parts.
