There are, however, empirical studies that
show no gains or even productivity decreases. A study by the Modelware project
(Dubinsky et al., 2006) in ?¬?ve different companies did not ?¬?nd any signi?¬?cant
difference between UML-based modeling and traditional manual approaches. Some
other studies, like Bettin, 2002, showthat productivity can also decrease when moving
from manual coding to standard UML. Next let??™s describe three cases based on the
domain-speci?¬?c approach in more detail.
Mobile Phone Applications at Nokia Nokia has reported a 1000% increase in
productivity when compared to earlier manual practices (Narraway, 1998; Kelly and
Tolvanen, 2000). This case deals with having a DSM solution to develop applications
for mobile phones. At this point, we should note that the DSM solution applied at
Nokia is not the same as reported in this book. TheDSMexample demonstrated earlier
and to be described in more detail in Chapter 8 is targeting relatively simple
administrative applications that are developed into already shipped phones.
22 BUSINESS VALUE
The case of Nokia is interesting for DSM as mobile computing is not a static
area but is constantly changing with different product requirements and product
features. Mobile phones and mobile computing are some of the fastest growing
markets today.
