2.3.2 Less Training and Guidance Needed
With DSM, introduction of new developers becomes easier. Obviously developers
who need to master just the problem domain become productive faster than those who
also need to learn the implementation domain and the mappings between the domains.
At Nokia, for instance, the domain knowledge contained in the modeling language
produced a faster learning curve for newemployees or transferred personnel. Earlier a
new developer was able to make applications and become productive only after being
exposed to the material for 6 months. With DSM, the time was reduced to 2 weeks
(Narraway, 1998; Kelly and Tolvanen, 2000).
When introducingDSMto existing developers in a domain, we can expect that less
training is needed as the concepts of the modeling language are usually already
familiar. Instead of learning both the particular problem domain and a solution
domain along with effective mappings between them, inDSMdevelopers ideally need
to learn just the problem domain. This minimizes the need for learning in the ?¬?rst
place and later reduces the quality assurance team??™s work to check that the
development guidelines are correctly followed.
Learning How to Model Today when most developers are more experienced
with coding than using formal modeling languages, the most fundamental change can
be learning howto model.
