Why a Business Case is Indispensable
Most HR tech projects fail not because of the technology itself, but due to the lack of a clear business case. Without concrete figures and a clear timeline, it's difficult for the board or CFO to allocate budget. This article helps you build a compelling business case step by step.
Calculate the Cost of the Current Problem
Before you can show what a solution will yield, you need to know what the current problem costs. This is what we call the "Cost of Inaction" (COI).
Calculate Direct Costs
| Cost Item | Calculation | Example |
|---|---|---|
| Manual work | Hours per week × hourly rate × 52 weeks | 10 hours × €45 × 52 = €23.400/year |
| Errors & corrections | Number of errors per month × cost per error × 12 | 5 × €200 × 12 = €12.000/year |
| Turnover due to frustration | Extra turnover × cost per departure | 3 × €15.000 = €45.000/year |
| Compliance risk | Probability × impact of fine or claim | 10% × €50.000 = €5.000/year |
Indirect Costs
Don't forget the less visible costs:
- Opportunity cost: What could HR do if they freed up 10 hours a week?
- Employee satisfaction: What does a low eNPS cost in terms of productivity?
- Employer branding: How does a poor digital experience affect your recruitment?
Tip: Be conservative in your estimates. A credible business case is stronger than an inflated story.
Define the Expected Returns
Now that you know what the problem costs, you can calculate what the solution will yield.
ROI Formula
``` ROI = (Expected savings - Cost of the solution) / Cost of the solution × 100% ```
Example
| Item | Amount |
|---|---|
| Annual savings (from step 1) | €85.400 |
| Annual license costs | €24.000 |
| One-time implementation costs | €15.000 |
| ROI year 1 | (€85.400 - €39.000) / €39.000 = 119% |
| ROI year 2+ | (€85.400 - €24.000) / €24.000 = 256% |
KPIs to Track
Define 3–5 measurable KPIs that you will monitor after implementation:
- Time savings in hours per week
- Reduction in manual errors (%)
- Lead time of core processes (e.g., onboarding from 5 to 1 day)
- Employee satisfaction (eNPS)
- Compliance score
Set Up a Timeline
A business case without a timeline is a wish list. The board wants to know: when will we see results?
Internal Deadlines
Look for natural moments that give your project urgency:
- Contract renewal: When does the current contract expire?
- Budget cycle: When does it need to be in the budget?
- Reorganization: Is a structural change planned?
- Growth: When do we reach the limit of the current system?
External Deadlines
- Legislation: New GDPR requirements, WVP adjustments, collective labor agreement changes
- Market: Vendor offers expiring, price increases
- Season: Avoid go-live in December (too busy) or July (too few people)
Example Timeline
| Phase | Period | Activity |
|---|---|---|
| Business case approval | Week 1–2 | Presentation to board |
| Vendor selection | Week 3–8 | Requirements, demos, references |
| Contract & decision | Week 9–10 | Negotiation and signing |
| Implementation | Week 11–18 | Setup, migration, training |
| Go-live | Week 19 | Go-live with support |
| Evaluation | Week 24 | First ROI measurement |
Write the Business Case One-Pager
The board doesn't have time for a 20-page report. Summarize your story on a single A4 page.
Template: Business Case One-Pager
Title: Business Case [Solution Name/Category]
The Problem _In 2–3 sentences: what is the current situation and why is it unsustainable?_
The Impact _What does the current problem cost us per year? (use figures from step 1)_
The Solution _What are we proposing and why does it fit our organization?_
The Investment _What does it cost (one-time + annually) and what does it yield (ROI)?_
The Timeline _When do we start, when do we see results?_
The Risk of Doing Nothing _What happens if we postpone this?_
Requested Decision _What specifically are we asking of the board? (budget, mandate, resources)_
Common Mistakes
| Mistake | Why it Fails | Solution |
|---|---|---|
| Only mentioning costs, no returns | CFO only sees a cost item | Always calculate ROI |
| Overly optimistic estimates | Loses credibility | Be conservative, use ranges |
| No timeline | No urgency, decision is postponed | Link to concrete deadline |
| Too technical | Board disengages | Speak in business language, not in features |
| No "cost of inaction" | Seems like doing nothing is free | Show what postponement costs |
The Most Important Lesson
A business case is not a sales pitch — it's an investment proposal. Treat it as such: with figures, risks, and a clear requested decision. The board doesn't need to fall in love with the tool; they need to be convinced of the investment.
