Planning Capacity and Sizing
Load

Flow
Question Reason Sample answer
What are your peak
and average daily
document ingestion
rates?
What are your peak
and average workflow
starts per day?
What are your peak
and average number of
documents attached to
a workflow?
How many peak
and average audit
trails do you have
per document and
workflows?
What is the average
number of document
views you have per
document during
workflow processing
and over the document
lifetime?
An influx of
documents can cause
an SLA exception
unless the system
is sized for peak
ingestion.
An influx of workflows
can cause an SLA
exception unless the
system is sized for
peak workflow starts.
Document volume
affects storage capacity
requirements and
determines size of
the tables that track
attachments.
Audit trails determine
how many rows are
in the tables that track
events.
Document views
determine the
retrieval rate and
probability of retrieval
after case closure.
Document views can
affect your tiered
storage approach and
demand for network
bandwidth.
At 5 year horizon, we project
ingestion of 345,000 documents per
day. This may peak to 1,000,000
documents per day during a single
day in a year.
At 5 year horizon, we project
starting 191,000 workflows per day.
This can peak to 382,000 workflows
per day during a single day.
At 5 year horizon, we project
an average of 2 documents per
workflow. This can peak to 5
documents per workflows during a
single day in a year.
We think we have average of 10
comments per document and 2
comments per workflow. Some of
the very difficult cases have 100
comments per document and 20
comments per workflow.
We have 3 document views
per document during workflow
processing. There is total of 3.1
document views over document
lifetime.
