Simulation Based Prospective Productivity Assessment of Complex Services
40
Based on this information, the project duration is ap-
proximately between 33 and 48 days, the most likely
duration is 41 days. The costs of the project vary between
17 and 25 thousand Euros and are most likely 21 thou-
sand Euros. These results represent valuable information
for the project planner. He is able to assess the risk of the
project and select a project organization that will with a
high probability lead to a successful project outco me.
4. Outlook
In order to verify and validate the conceptual productiv-
ity model and the simulation system broader studies will
be conducted. Furthermore, more detailed use cases from
our project partners will be gathered and will assist to
prove the usefulness of a dynamical assessment of ser-
vice productivity. This will enable service planners and
managers to take reliable decisions based on a system-
atical support.
As a further enhancement an optimization algorithm
will be developed and connected to the simulation tool.
This will close the loop by identifying optimal organiza-
tional settings under given circumstances of uncertainty.
