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

BP Execution Measurement Model (BPEMM)( )

• Provides a set of execution measures for BPs implemented by servicesimplemented by services

Main objective: to relate business goals of the organization and specifics of the BP to its real execution

(Basili, 1992)

BPEMM measures: selection,

implementation and collection

Measures specified using the Software Measurement Ontology

Measures specified using the Software Measurement Ontology (SMO) (García et al., 2005)



• BPEMM tridimensional organization




• BPEMM – Execution Views

Generic BP execution:measures are related to genericg

process characteristics that

are not themselves related to the

type of BPtype of BP

Lean BP execution:measures mainly focused on the detection of defined types of waste

S i tiServices execution: 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)cost of human resources (mainly)

Quality: yquality characteristics and errors

Flexibility: ability of a BP to react to changes




• BPEMM Granularity levels

Service execution view general definitions

• Definition of measures for the service execution view

g

• For each measurable concept several goals, questions and execution measures are defined



Service execution view examplesp• Time dimension

Response Time (RT): Guaranteed time interval for the

ti f th f t ( i i i )execution of the response of an event (service invocation)



Service execution view examplesp

• Time dimensionResponse Time (RT): Guaranteed time Interval for the Response Time (RT): Guaranteed time Interval for the

execution of the response of an event (service invocation)



Service execution view examplesp

• Quality dimensionDependability: Guaranteed availability for the service,Dependability: Guaranteed availability for the service, guaranteed reliability for the service (service invocation)



Tool supportpp

• BPEMM ProM plug-inDefined prototype to support the BPEMM execution measures visualizing the execution measures in BPEMM.

So far only the Time dimension for the Generic BP execution i i i l t d i ti f ti


view is implemented, so service execution measures for time are included in Activities time


Conclusions and future work

• The BPEMM execution measurement model provides a set of measures for the execution of BPs realizedprovides a set of measures for the execution of BPs realized by services organized into 36 categories from three different dimensions

• The service execution viewmeasures services execution both from the point of view ofmeasures 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 inProM framework, the ProM BPEMM 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.
