I’m continuing on my “Skills” theme this month which is addressing some of the biggest bottlenecks in recruiting.  Think about this:

It’s Q3. Your VP of Engineering walks into your office and says she needs twelve people who can do “xyz skill” and need to be fully ramped up by January.

You nod. This doesn’t faze you because it happens all the time. You open a fresh req. You start the clock on the search.  And you know that, realistically, all twelve of those roles won’t be filled before spring.

And here’s the part that is bothersome: you have no idea whether anyone already at the company has 70% or more of those skills. Not a clue. The resumes in your file are frozen at the moment of hire, the org chart only tells you titles, and titles lie. So you go to market to find capabilities you might already own.

We do this constantly. And we call it recruiting.

The problem isn’t that you can’t find talent. It’s that you can’t see the talent you already have.

We have spent two decades building sophisticated intelligence on external candidates: proactive CRM campaigns, sourcing data, pipeline analytics, the works. Meanwhile, the data on our own workforce is somewhere between thin and fictional. A job title from 2019. A performance review that grades how well someone does their job but never asks what else they can do. A skills field in the HRIS that three managers filled out and four hundred ignored.

Your Applicant Tracking System (ATS) knows more about strangers than your HRIS knows about your own people.  That’s not a system problem.  It’s a blind spot we’ve chosen to live with.

A talent inventory is a forecast, not a catalog

Let’s kill the most common misconception up front. A skills inventory is not a competency framework binder that sits on a shelf. It’s not an HR vanity project. And it’s definitely not a one-time spreadsheet you build, celebrate, and never touch again.

A real talent inventory is a forecasting instrument. The entire point is to answer one question: Where will we be structurally short 12 to 18 months from now and can we build our way there instead of buying our way there?

Recruiting is reactive because we wait for a gap to announce itself as a vacancy. Skills mapping flips that. When you know what your workforce can actually do (and what it’s one training cycle away from doing), you stop discovering gaps the day a hiring manager panics and actually start predicting them a year out.

That changes everything about your time-to-fill, because the best way to win a 90-day search is to have started it 200 days early.

How to actually build this without boiling the ocean

Here’s the framework. Notice that every step is a shift in the question you ask.

Instead of cataloging titles, map skills. Titles are containers, not contents. Two people with “Senior Analyst” on their badge may share a title and almost nothing else. Inventory the verbs and what people do, not the nouns on the org chart.

Instead of recording presence, capture proficiency. “Knows Python” is useless. Can do it under deadline, has done it once in a bootcamp, or could teach it to a team of five, are three completely different inventory entries. Grade for depth, not just existence.

Instead of mapping only what people have, map what they’re adjacent to. This is where the real value lies. A skill someone has plus a realistic ramp time gets you to a skill they could hold next quarter. Adjacency is where your hidden capacity lives, and it never shows up on a resume.

Your inventory is only half the equation. The other half is demand. Sit with the business and ask where it’s going.  What is the product roadmap?  Are there plans for expansion?  What exactly does their business plan require in terms of employee skillsets?  The gap is simple math: future demand, minus current inventory, minus what you can realistically buy externally.

Do that, and you don’t have a spreadsheet. You have an early-warning system.

“This sounds like a data project we’ll never finish”

If you try to inventory every skill of every employee across the whole company, you will fail. You’ll spend nine months building a taxonomy, lose momentum, and your beautiful framework will rot in a SharePoint folder next to the 2023 engagement survey nobody acted on. So don’t do that.

You don’t need perfect data. You need directional data on the roles that matter most. Start with the 10 to 15 capabilities most critical to your next 18 months.  These are the ones where a shortage would actually hurt.  Ignore the rest for now.

And before someone in the comments says it: yes, the new wave of AI and agentic tools that promise to automatically infer skills from project data and internal systems is genuinely getting useful for this type of exercise. For the first time, the problem on skills data is solvable at scale. But garbage in is still garbage out, and inferred proficiency is a hypothesis, not a fact. Keep a human in the loop to validate before you make a hiring decision on it. AI reviews the inventory. People still sign off on it.

Early talent already does this — you just don’t call it that

Here’s the proof of concept that’s been hiding in your campus program the whole time.

When you hire a college senior, you are not buying a finished skill set. You can’t because they don’t have one yet. You’re buying trajectory. The entire university recruiting platform is built on a question most of your workforce planning never asks, “What can this person become in 18 months and what do we need to teach to get there?”

Early talent forces you to think in proficiency plus ramp up time and in trainability. That is exactly the thought that skills mapping requires, you’ve just only been exercising it on 22-year-olds. The best campus programs already map intern and new-grad capabilities against the roles they’ll grow into. Take that lens, the one you trust completely for early talent, and point it at the rest of your org.

If you’d bet on a new grad’s trajectory, why won’t you bet on the trajectory of someone who’s already proven they can deliver inside your company?  Stop treating your existing workforce as a fixed asset. Start treating it the way you treat a great intern, as potential you can deploy.

The bottom line

A talent inventory won’t eliminate external hiring, and it shouldn’t. But it will tell you which of next year’s “emergency” searches were actually predictable and which ones you could have built for, internally.

So here’s my question for you: do you actually know what your current workforce can do or are you about to run an expensive search for a skill that’s already sitting on your payroll?

If you want help turning a pile of stale HRIS data into a forecasting tool you’ll actually use, that’s the kind of problem we love at ES Talent Solutions. Reach me directly at estewart@estalentsolutions.com and let’s map what you’ve already got.
