The document proposes a BP Execution Measurement Model (BPEMM) to measure service execution as part of business process execution. BPEMM organizes measures across dimensions of time, cost, quality and flexibility. It defines measures for a service execution view to assess individual services and their composition in business processes. The authors developed a ProM plugin to evaluate BPEMM measures for time in generic business processes, and plan to extend it to fully support the model across all defined measures.

2. A proposal on service execution measures for the improvement of BP realized by services
Introduction
• "Measurement is the first step that leads to control and
eventually to improvement. If you can’t measure something,
you can’t understand it. If you can’t understand it, you can’t
control it. If you can’t control it, you can’t improve it.“
(Harrington, 1991)
The realization of BPs with
services provides the basis

Services execution has
to be measured as part of
BPs execution to be able
to improve BPs

• BPEMM – Execution Views
Generic BP execution:
measures are related to generic
g
process characteristics that
are not themselves related to the
type of BP
Lean BP execution:
measures mainly focused on the detection of defined types of waste
Services execution:
S i ti
measures to assess the execution of services realizing the BPs

• BPEMM Devils’ Quadrant aspects
Time:
duration and capacity of the BP
Cost:
cost of human resources (mainly)
Quality:
y
quality characteristics and errors
Flexibility:
ability of a BP to react to changes

• Definition of measures for the service execution view
• For each measurable concept several goals, questions and
execution measures are defined

Tool support
pp
• BPEMM ProM plug-in
Defined prototype to support the BPEMM execution measures
visualizing the execution measures in BPEMM.
So far only the Time dimension for the Generic BP execution
view i i l
i is implemented, so service execution measures f ti
t d i ti for time are
included in Activities time

8. A proposal on service execution measures for the improvement of BP realized by services
Conclusions and future work
• The BPEMM execution measurement model
provides a set of measures for the execution of BPs realized
by services organized into 36 categories from three different
dimensions
• The service execution view
measures services execution both from the point of view of
the BP invoking services, and within services themselves
• Tool support for evaluating measurement results
Is needed, for which we have developed a prototype for the
ProM framework the ProM BPEMM plug-in,
framework, plug in
we are now extending it to include all the defined measures,
to be able to assess the complete proposal in a case study.
