Predicting Talent Needs Before They Become Urgent
The Hiring Panic That Didn't Have to Happen
Almost every urgent hiring crisis looks sudden from the outside: a key department suddenly understaffed, a critical skill nowhere to be found, a project stalled for months waiting on the right person. In reality, most of these moments were visible years in advance to anyone actually looking for them. The gap is rarely a lack of warning signs, it is a lack of a system built to notice them early.
What Workforce Forecasting Actually Involves
Workforce forecasting is the practice of predicting an organisation's future talent needs, in terms of headcount, skills, and structure, well before those needs become urgent. A comprehensive academic review of workforce planning research, spanning more than 180 studies published between 1959 and 2021, found that the field has evolved through analytical, simulation, and empirical modelling approaches, each suited to different workforce questions, from staffing levels to skill gaps to attrition risk (Peck, 2025). In other words, forecasting talent needs is not guesswork, it is a genuine, decades-old discipline with its own body of research behind it.
The Maturity Gap Most Companies Don't Talk About
Despite this, most organisations are still not doing it well. Research from Deloitte, cited by SHRM Labs, found that only 11 percent of organisations demonstrate genuine strategic maturity in their workforce planning approach (SHRM Labs, 2024). The vast majority are effectively planning reactively, adjusting only once a shortage or surplus has already become visible, and costly.
Why So Many Organisations Are Caught Off Guard
The consequences of that reactive approach are already visible at scale. SHRM's State of the Workplace research found that 84 percent of organisations reported facing labour shortages in some form (SHRM, 2023, as cited in Credly, 2023). Waiting for a shortage to appear before responding leaves very little runway to recruit, train, or restructure before the gap starts affecting delivery.
Build or Buy: The Hidden Cost of Waiting Too Long
Forecasting early also changes the economics of closing a talent gap. Research by talent analyst Josh Bersin, examining three organisations in depth, found that building skills internally through training and development was roughly six times less expensive than hiring the same skills externally (as cited in Deel, 2026). Forecasting far enough ahead is precisely what makes the cheaper option, developing existing employees, actually feasible in the first place.
What This Means for HR Teams
The practical takeaway is straightforward, if not always easy to act on. Waiting until a role sits empty is the most expensive way to solve a talent problem. Forecasting talent needs months or years ahead turns an eventual scramble into a manageable, and considerably cheaper, plan.

Strong point right at the start most hiring crises only look sudden from the outside. That framing makes the rest of the argument land.
ReplyDeleteThe build versus-buy comparison was the part I found most convincing. If developing skills internally is around six times cheaper, then forecasting early isn't just good planning, it's what makes the cheaper option possible at all. Well argued!
This is an interesting discussion on workforce forecasting. I agree that organizations should identify future skill gaps before they become urgent hiring problems. Early forecasting also gives HR more time to focus on upskilling and reskilling existing employees rather than relying only on external recruitment. A proactive approach can reduce costs and help organizations build a stronger workforce for the future.
