The common ways to keep a departing expert's knowledge (recording them, hiring a consultant, using a wiki, or using dedicated capture software) differ in whether they actually reach tacit judgment and whether they are repeatable. Recordings and wikis mostly capture what was already written; structured capture elicits the judgment and turns it into reusable artifacts.
If you have decided that letting an expert's knowledge walk out the door is not acceptable, the next question is how to keep it. Most organizations weigh some mix of four options: record the person, hire a consultant to run a knowledge-transfer engagement, ask them to write it into a wiki, or use software built for the job. Each has a real place, and each has a failure mode worth understanding before you commit time and money.
The four common options at a glance
The honest short version:
- Record it (Zoom, Otter, a Loom video). Cheap and fast to do, but it produces a haystack. A successor with a specific problem cannot search two hours of talking for the one answer they need. Recording vs structured capture.
- Hire a consultant for a knowledge-transfer engagement. High quality when done well, but it is a one-off project with a one-off price, and the knowledge and method leave with the consultant. Consultant vs software.
- Use a wiki (Confluence, Notion, SharePoint). Great for storing what people write, but it depends on experts documenting their own tacit knowledge, which they reliably cannot. Why a wiki is not enough.
- Use a dedicated capture tool. Built to elicit tacit judgment through structured sessions and turn it into successor-ready artifacts, repeatably, at a fraction of consultant cost.
The test that separates them
There is one question that cuts through the comparison: does the approach actually get at tacit knowledge, the judgment an expert cannot easily put into words, or does it only capture what they were already able to write down? Recordings and wikis mostly capture the latter. The knowledge most likely to be lost, and most expensive to rebuild, is the former.
A recording is a haystack and a wiki is an empty page. The value is in the needle: the specific judgment a successor can act on.
The other test: is it repeatable?
The second question is whether the approach leaves you a system or a souvenir. A consultant engagement solves one departure and ends. A recording sits in a drive. A dedicated tool turns each capture into a compounding asset: the more you run, the clearer your risk picture and the more your organization keeps. For a recurring problem, and departures are now recurring given falling tenure, a repeatable system beats a one-time fix.
Where TacitTalks fits
TacitTalks is the dedicated-tool option: it runs a guided capture session, gets at the tacit judgment through structured questions, and produces a successor briefing, a dependency map, and a risk view automatically. You can start free with a Knowledge Risk Assessment to see where your exposure is, and for a single expert the Continuity Pack handles the whole capture for a flat fee. The articles below compare it honestly against each alternative.

- Hiring a Consultant for Knowledge Transfer vs Using SoftwareA knowledge-transfer consultant delivers a great one-off result at a one-off price. Here is how that compares to a repeatable software approach.
- Why an Internal Wiki Is Not Enough to Capture Expert KnowledgeConfluence, Notion, and internal wikis are great for storing what people write. Here is why that is not the same as capturing what your experts know.
Common questions
- What is the best way to capture a departing employee's knowledge?
- The most effective approach elicits tacit judgment through structured sessions and turns it into usable artifacts, rather than just recording the person or asking them to document their own job. Recordings produce an unsearchable haystack and self-documentation misses the judgment that matters most.
- Is it cheaper to record an exit interview than to use software?
- Recording is cheaper to do but far less useful. A raw recording is not searchable or actionable when a successor faces a specific problem later. The cost shows up downstream, in the months a successor spends rediscovering knowledge the recording technically contains but does not surface.
- Should we hire a consultant or use a tool?
- A consultant engagement can be high quality but is a one-off project at a one-off price, and the method leaves when they do. A dedicated tool is repeatable and compounding, at a fraction of the per-capture cost, which fits better now that departures are recurring rather than one-time events.
