Somewhere in a conference room, an HR leader is presenting a requirements document to a vendor.
It has been weeks in the making. Multiple stakeholders contributed. The document runs to thirty pages. The vendor reviews it, nods, asks a few clarifying questions, and confirms it can all be built.
Six months later, during UAT, the same HR leader is staring at a leave management workflow that technically works — but doesn't account for how their organization handles sick leave encashment for contract staff across three different states. Nobody captured that. It wasn't in the document.
The requirements phase is where most HR tech transformations are quietly decided. Not in vendor selection. Not in implementation. Here — in the phase that gets the least attention and the most assumptions.
The document exists. The requirements don't.
Most organizations believe they've done requirements properly because they have a document. It has sections. The vendor reviewed it. Someone signed off.
What the document usually contains is a list of features the organization wants. A leave management module. An employee self-service portal. An automated payroll integration. A performance management workflow.
These sound like requirements. They are not.
They are solutions in disguise.
A feature request tells a vendor what to build. A real requirement tells a vendor what problem needs solving — and why the current situation isn't working. The difference isn't just semantic. It determines whether what gets built actually fits the organization, or merely exists within it.
When you write "we need a leave management module," the vendor builds a leave management module. Specifically, the one they've already built for their last fifteen clients — with their standard configurations, their standard workflows, their standard assumptions about how leave gets applied, approved, and reported.
When you instead describe the actual problem — that managers are approving leave verbally and records are being maintained in Excel, creating payroll discrepancies at month end, and that the three-tier approval required for senior roles is being bypassed because there's no system to enforce it — the vendor builds something that solves that. Something configured to your reality, not their template.
The difference in outcome between these two documents is significant. The extra effort to produce the second one is far smaller than most people expect.
Why this keeps happening
The requirements phase almost always gets rushed. There's usually a deadline — a financial year boundary, a contract renewal, a leadership commitment made before the project was fully scoped. The requirements document becomes something to produce quickly rather than something to get right.
There's also a harder reason. Writing real requirements means someone needs to understand the business deeply enough to describe not just what people want, but what is actually broken and why. That's a different skill from filling in a template. Most organizations don't have that person in the room during requirements — and don't realize it until implementation.
Poor requirements gathering is consistently cited as the leading cause of software project failure, responsible for over 39% of cases. This isn't specific to HR tech. It's a broad technology finding that has held consistent for over two decades. The HR industry isn't an exception — it just feels the consequences more directly, because the systems being built touch every employee in the organization. (Gartner)
What real requirements actually look like
A real requirement starts with a problem, not a feature request. Before a vendor is allowed to propose a solution, four questions need honest answers.
What is currently breaking — and how often? Not a general sense that something is inefficient. A specific description of what fails, when, and what the downstream impact is. If leave approvals are being missed, how many per month? Which teams? What happens to payroll when they are?
What is being done manually that shouldn't be? Most organizations have workarounds that have become invisible because people have been running them for years. The spreadsheet someone maintains on the side. The WhatsApp message that substitutes for a formal approval. The monthly reconciliation that takes three days because two systems don't talk to each other. Each of these is a requirement hiding in plain sight.
Who is affected and how? A requirement that doesn't name the affected stakeholder is incomplete. Finance experiences a payroll problem differently than an employee experiences an approval delay. Both matter. Both need to be captured separately.
What does good actually look like — in real terms, not system terms? Not "we want a dashboard." But "the HR business partner needs to see pending approvals for their business unit without raising a ticket to the HRIS team." Specific. Practical. Not tied to any particular technology.
The diagnostic — where most requirement documents break down
If you have a requirements document in front of you right now, or are about to build one, these questions are worth asking honestly.
Does every requirement describe a problem — or a feature? If you removed the name of any particular HRMS from the document, would it still make sense? Real requirements are tool-agnostic. If your document only makes sense in the context of a specific system, it has already skipped the problem-definition step.
Were the requirements written by someone who has seen how the business actually operates — or by someone who knows what an HRMS can do? Both people are necessary. Only one of them should be leading this conversation.
Have the edge cases been captured? Standard processes are easy to document. The exceptions — the cases that happen 15% of the time but account for 60% of the manual effort — are where most documents go quiet. Ask specifically: what happens when this process breaks down? How is it currently handled?
Is there a stakeholder whose input is missing? Finance. A specific regional team. A group of employees on a non-standard contract. There is almost always someone who wasn't in the requirements workshops and whose workflow shows up as a surprise during UAT.
Research shows that 80% of rework in technology projects can be traced back to poor requirements. Rework during an HR tech implementation isn't just expensive in budget terms. It costs time, strains the vendor relationship, and creates the kind of organizational fatigue that makes every phase after it harder to execute. The requirements phase is the cheapest place to get things right. It gets progressively more expensive to fix the same problem later. (Gartner)
What this actually costs
Organizations rarely see the cost of poor requirements as a single line item. It doesn't appear as "requirements failure — ₹40 lakhs." It shows up as extended timelines, configuration rework, additional consulting days, a UAT that runs two months past its end date, and a go-live that gets delayed because the system isn't ready in ways nobody anticipated.
It also shows up in something harder to measure — a system that goes live but never quite fits, because it was built on a description of what people wanted rather than what they actually needed. Users find workarounds. Adoption stalls. The investment quietly underperforms for years.
The organization that spends a few extra weeks in the requirements phase — genuinely describing problems rather than listing features — consistently arrives at implementation with less rework, fewer surprises, and a vendor who is working from real understanding rather than assumptions.
A final thought
The requirements document is not a formality. It is the single most important artifact in an HR tech transformation — and the one that gets the least scrutiny before it reaches a vendor.
Getting it right doesn't require as much time as people think. It requires a different kind of thinking. Less "what do we want the system to do" — and more "what is broken, who feels it, and what does actually working look like."
The vendor will build what you describe. Make sure what you describe is the problem — not the solution you've already assumed.
