Business process approach to e-
business analysis
E-business as way of simplifying business processes
Need to understand the dynamics of processes and their interaction
Evaluate the real benefit of e-business
Functional to process view

Some modelling approaches Process mapping
E.g. IDEF Diagrammatic
Static tools E.g. spreadsheets
Dynamic tools Queuing theory Simulation (discrete event) System dynamics (continuous)

Requirements for modelling Multi-level / hierarchical
Gradually add detail in design or Aggregate detail in operation for
speed/simplicity Randomness
Recognise real world is not predicable Passage of time
Recognise the dynamics of the real world has critical impact
Flow of information AND product Few true examples of this and yet this
coordination has key performance impact Modelling of e-business systems
Question of how to model

Project aims To investigate the suitability of simulation as a technique to analyse the effects that e-business has on the business processes of manufacturing companies.
To look at the differences between traditional and e-business processes for different e-business scenarios in the manufacturing sector.
To develop the methodology for the use of these tools and techniques.

Analysis of Current Process models
Comparison of models against case studies. Find differences between process models and
cases (especially related to e-business) Development of templates/components
for e-business. Initially thought templates would be all
encompassing high level Found templates do not adjust rigidly to
proposed business process models Decided to use smaller clusters that represent
e-business activities

Summary
Analysis of BPS levels Description of e-modelling requirements Change observed mainly in dynamics of
processes Change in dynamics (<time, <human
involvement, < redundancy) Change in performance metrics (>reliability, >
quality of information) Analysis of current business process
models Creation of e-process templates

Conclusions Simulation proved to be useful for
the analysis of e-business implementation –highlighting potential benefits/problems.
Generic activities can be identified for e-processes and can be operationalised.
Are they useful? We’ll find out.
