What is simulation?
Simulation provides the ability for an organization to not only define a process but model and demonstrate its efficiency. Using time, cost and utilization as success indicators

Simulation in the BPM lifecycle
What is modeling?
Where does it fit in the project lifecycle?
What are the components of modeling?
Simulation
Documentation
Standards

TIBCO Simulation
Developed in conjunction with the University of Hamburg in Germany
Helps the business to identify
Where potential bottlenecks are
Where errors might occur
Is this is a cost effective way of administering business
Compare different approaches
How many resources are required to process this volume of work
What timeframes can work be processed in

When should simulation be done?
The process of implementing a BPMS tool will provide a level of benefit
Perhaps a small ROI but it will be provided in a timely fashion
Typically an organization does not have detailed metrics to support simulation
Watch out for analysis paralysis
Simulation is a yard stick in the first project

Simulation inputs
How much does a person in this role cost per hour?
How many people do we have in this role?
How many transaction do we receive?
How are those transactions received?
All at once – batch style
Through out the day constantly
Continuous drip feed no real consistent timing
How long does this activity take?
What is the optimal utilization of my staff?
What is an acceptable lag time for work to wait?
Conditional processing
60% of transactions have a supervisor step

Simulation of the process

Setting up Simulation
Create a Process
Add Participants
Specify Unit Costs of Participants
Specify Duration of the Activities and Case Start Information
Associate Participants with Activities
Add Data Fields

Running the Simulation
Prepare the Simulation
Select Simulation Perspective
Run Simulation

Simulation Results

Changing the Simulation Parameters
Change the parameters
Re-run the simulation
Compare Simulation Results

Using Real Data
Import historical data
Mine data

Approach
Ensure you have outcomes for your As-Is process
Number of transaction processed per day
Keep the duration of simulation to a small end to end duration first
Per day or per hour
Less chance for human aspects to skew data
Once you have a baseline, ROI analysis is far more realistic and believable
Distribution is key to average work times. E.g.
Exponential loads a lot of cases in a short timeframe. This will result in long average processing times.
Shared resources will throw extreme minimum and maximum

Work distribution
Constant – Every 5 minute a case is triggered.
Drip feed constantly through out the day
Uniform – Cases are started randomly at intervals between the min and max times
Drip feed through out the day at varying times
Normal – If I have a mean of 10 secs and a standard deviation of 3 secs, then 68% of cases will be randomly started between 7 secs
This allows the grouping of the bulk of cases within a timeframe.
Still a drip feed
Exponential – 50% of cases are started under the mean and 50 % over the mean. This is front loaded.
This caters for customers who receive large amounts of data in the morning and taper off to the afternoon
7 13 6 secs 68%

Actual results
Constant – work arrives consistently at fixed intervals.
Avg - 162
Min - 15
Max - 1005
Uniform – cases arrive steadily throughout the day, the difference determined randomly between the defined timelines.
Avg - 178
Min - 15
Max - 1022
Normal – the bulk (68%) of cases arrive steadily throughout the day, the difference determined randomly within one Std deviation. Less knowledge about the extremes.
Avg - 187
Min - 15
Max - 1023
Exponential – bulk arrivals in the morning that taper off through out the day. The difference between starts increases as time goes on.
Avg - 215
Min - 15
Max - 1041

Loop definition
Max Loop Count - after the specified number of times through it. You must enter the Max Loop Count (the number of times you want cases to follow the loop).
Example

Once a loop is in place. New tab “Simulation Control” appears in properties

Loop options
Once a loop is in place. Extra tabs appear in the properties tab of the preceding activity immediately prior to the condition.
There are three options
Elapsed time
Max loop Count
Normal Distribution

Watch out for
Average case times
Simulation doesn’t match up to reality, but you can get very close
The business does not always tell the truth
Watch them processing as part of your discovery
Shared resource across many activities will skew average processing times
Break them up into smaller more accurate teams
Work is processed from 9 – 5 each day
Work can still be delivered outside of these hours
Starting date and time can be configured

Summary
Standards based process modeling tool – Eclipse, BPMN, XPDL
Use by all those involved in process
Business Analyst, Process Developer, Process Owner
Modeling, Simulation, Implementation, Deployment
Simulation
Model process
Demonstrate efficiency
Time, Cost, Utilization as success indicators
Change parameters and rerun simulation
Only implement when happy
