The Rule 26(f) conference of the parties is one of the highest-leverage moments in any case. The decisions made there — about scope, formats, search methodology, and privilege protection — shape the cost and burden of everything that follows. Parties who arrive with worked-out positions tend to set the terms; parties who improvise tend to inherit someone else's.

What Rule 26(f) actually requires

Federal Rule of Civil Procedure 26(f) requires the parties to confer early and to develop a proposed discovery plan, including any issues about disclosure, discovery, or preservation of electronically stored information and any issues about claims of privilege. In practice, that means ESI is not a side topic — it is a required agenda item, and the conference is your opportunity to reach agreement before disputes calcify.

The companion to 26(f) is Rule 26(b)(1), which since the 2015 amendments frames discovery around proportionality: the needs of the case, the amount in controversy, the parties' resources, the importance of the issues, and whether the burden outweighs the likely benefit. Proportionality is your strongest argument for keeping scope reasonable — but only if you come prepared to articulate burden concretely.

Why preparation wins

You cannot argue proportionality in the abstract. "That request is burdensome" is weak; "that request reaches four systems, roughly 2.1 million documents, and an estimated review cost we can quantify" is the kind of specificity that moves a court.

The ESI checklist

Scope and sources

  • Which custodians and date ranges are genuinely in scope?
  • Which data sources are involved — email, Microsoft 365, Teams, Slack, Google Workspace, mobile, cloud, structured databases?
  • Are there sources you will argue are not reasonably accessible because of undue burden or cost, and can you support that with specifics?

Search methodology

  • Will the parties use search terms, technology-assisted review, or a combination?
  • How will methodology be validated, and how transparent will the parties be about it?
  • What is the process for testing and refining search terms before they are locked in?

Production format

  • What format will documents be produced in, and which metadata fields will accompany them?
  • How will modern collaboration data — threaded chats, reactions, edits — be rendered so it is usable and faithful?
  • How will redactions, families, and de-duplication be handled?

Privilege protection

  • Will the parties seek a Federal Rule of Evidence 502(d) order to guard against subject-matter waiver from inadvertent production? In high-volume matters this is one of the most valuable protections available, and it is far easier to obtain at the outset.
  • What is the privilege-log format, and can categorical logging reduce burden?
  • How will clawback of inadvertently produced material work in practice?

Preservation

  • What is the scope of each side's preservation, and are there sources where preservation is disproportionate?
  • Are there short-retention or ephemeral sources that need specific treatment?

Bring positions, not just questions

The difference between a productive conference and a contentious one is usually preparation. Walking in with a draft ESI protocol — your proposed formats, your search approach, your 502(d) language — lets you negotiate from a baseline you designed. It also signals competence, which changes the tenor of the entire case.

A standing Rule 26(f) checklist, maintained as part of your playbook and updated as your data sources and the case law evolve, means counsel never has to build these positions from scratch under deadline. That is the whole point of a playbook: the hard thinking is done in advance, so the conference is execution, not improvisation.
