Produced Gigabytes | Pulse

Produced Gigabytes - The number of average GBs
contained in a production set.

Cutting the clutter.

The average number of gigabytes contained in a production set has decreased drastically from 2008 (~100GBs produced) to 2013 ~30GBs produced). This strongly supports the notion that parties are becoming smarter about what they produce.


It's all about email.

While the volume of unstructured data and the complexity of data stores proliferate, email still remains the dominant data form for ediscovery. However, in 2013 there was a decline in the percentage of email processed for the first time in five years.

Large cases have a more even split between loose files and email, whereas small cases tend to be more email which stabilized the dichotomy in data types.

Data Type - Email

Data Type - The average percentages of email
and documents processed, before filtering.


Average Number of Custodians Per Project

Custodians Per Project - The average number of custodians in a review database.

Less is truly more.

The average number of custodians collected per ediscovery project has declined significantly in recent years.

In no small part, this trend is likely due to the fact that cost-conscious litigants are leveraging new collection methods and advanced pre-filtering technologies, combined with more effective custodian interviews.

client-specific data. At no point will the Pulse reveal a particular matter or client associated with Kroll Ontrack.


What are some examples of Pulse Benchmarks?

Some types of metrics contained in the Pulse Benchmarks include:

  • The average number of custodians per ediscovery project
  • Data format source
  • Average collection versus production volumes
  • And more!

New metrics will be released periodically by Kroll Ontrack. The best way to stay up to speed when new metrics are released is to follow the Kroll Ontrack blog, where new metrics will be announced.
