Feeds directly into the
sizing spreadsheet.
Used to adjust the
workload modeled in
the sizing spreadsheet.
Used to calculate the
percentage of active
users.
Determines available
worker capacity to
process cases, based
on average case
processing time.
Determines the size of
the workflow activity
tables.
Determines the size
of workflow activity
tables.
There are 2500 concurrently logged
in during peak busy hour.
There are 10 business transactions
per user during a busy hour.
During a busy hour, the average
transaction lasts 60 seconds and
there are 10 transactions. The
percentage of time users are active
is:10*60/3600=16% active
On average, a worker works 7.5
hours per day, 260 days in a year.
If one case takes 15 minutes, one
worker can process 4 cases per
hour and 7,800 cases per year
(4*7.5*260=7,800). 2,500 users can
process 19.5 million cases per year.
We process 10,000 cases per month,
but occasionally we get a seasonal
influx of 100,000 cases per month.
Average is 5 days but some cases
can stay open as long as 90 days.
