The riskiest moment in eDiscovery often isn’t the collection or the production, it’s the handoff in the middle where messy data has to become reviewable evidence. We walk through that end-to-end workflow from the point of view of digital forensics and the data solutions team that has to normalize, parse, and translate real-world exports into something counsel can rely on. Steve Davis brings a kitchen metaphor that lands: you need the right “chef de cuisine” to keep the line moving, even when too many cooks are touching the same case.

Our guest, Mike Johnson from Purpose Legal’s data solutions group, gets practical about what’s breaking legacy workflows right now: Microsoft 365, Purview eDiscovery exports, and the modern attachment problem. We talk about why platform changes ripple into scripts, column mappings, and processing logic, and why the only sane response is disciplined testing. Think sandbox environments, controlled variables, repeatable exports, and documenting what actually happens rather than repeating what you heard somewhere else. We also dig into why Purview’s August 2025 changes can improve efficiency while still forcing teams to adapt.

Then we get into the issue that can make or break an investigation: versioning. When the case needs the file as it existed years ago, “current version” may not be good enough, and retention settings might not have been enabled when it mattered. We close by looking ahead at chat evidence and AI artifacts, from WhatsApp and Telegram to ChatGPT and Claude, plus how client-facing teams can help by looping technical experts in early and collecting what’s needed and nothing more.

Your phone is not a tiny laptop, and treating it that way is how mobile device collections blow up in litigation and investigations. We talk through what actually makes mobile forensics hard: layered control across the device, iOS or Android, and the messaging apps where the evidence lives, plus constant changes in encryption, APIs, and forensic tooling.

We also get practical about what makes a mobile device collection defensible. From our kickoff and scoping calls to chain of custody and documentation, we explain how we set expectations with outside counsel, in house teams, and nervous custodians, especially in BYOD scenarios where personal and work data commingle. Privacy is always on the table, so we dig into when targeted acquisition can reduce risk and when you still need to collect to preserve because preservation in place is rarely an option on phones.

Then we break down the core decision points: targeted eDiscovery workflows versus full file system extraction for deeper forensic analysis, the real world disruption of taking a phone for hours or even days, and what to do when critical information is missing. Sometimes you cannot recover deleted artifacts, but you can analyze the gaps, correlate surrounding metadata, and assess whether the absence supports a spoliation narrative or an innocent explanation. We close by previewing the “what happens next” step: how Data Solutions normalizes raw mobile artifacts so reviewers can consume the data accurately across eDiscovery platforms, down to emoji fidelity and clean productions.

The Dangers of DIY Collections: When "Good Enough" Can Create Risk

In the inaugural episode of Evidence Matters, digital forensics experts Jerry Bui and Steve Davis tackle a common question facing corporate legal teams, litigation professionals, and eDiscovery practitioners: When is it appropriate to handle data collections internally, and when does it make sense to bring in a forensic expert? 

The discussion explores the risks of "DIY" collections, including challenges related to chain of custody, metadata preservation, defensibility, and expert testimony. Jerry and Steve compare the roles of IT teams, law firms, and independent forensic consultants, explaining why collecting data for litigation or investigations requires a different skill set than simply accessing information. They also examine how evolving technologies, cloud platforms, mobile devices, and emerging data sources continue to reshape forensic best practices. 

Listeners will gain practical insight into:

•  The difference between IT collections and forensic collections 
•  Common risks that can arise from self-collection efforts 
•  Why defensibility matters in litigation and investigations 
•  The importance of independence, documentation, and expert testimony 
•  How forensic best practices continue to evolve alongside technology 

Whether you're an in-house counsel, litigation support professional, eDiscovery manager, or outside counsel, this episode offers a practical look at how collection decisions made early in a matter can have significant downstream consequences.
