The piece of HR tech I had to ram through against open team resistance was a structured 1:1 + skills-matrix tool (we landed on Lattice after testing a French alternative called Javelo). The resistance was real. Four of my senior managers told me to my face that "this is admin theater" and that they would not use it.
What I did wrong the first time: I rolled it out as a top-down mandate. Mandatory weekly check-ins, mandatory skill ratings, mandatory goal updates, mandatory peer feedback every quarter. Adoption was 31 percent at week 6. Half-filled forms. Anger.
What worked the second time: I killed all the rules and replaced them with one thing. We made the tool the single source of truth for promotion and raise decisions. Cleared out the email threads, the Slack DMs, the side conversations, the post-call hallway debriefs. The conversation about your next salary review now lives inside the tool, with your manager's notes attached to specific 1:1 entries from the past 6 months.
Three weeks after that change, adoption hit 89 percent. Not because the tool got better. Because there was no longer a back-channel that paid more than the tool did.
For French and EU teams specifically, two things tipped the skeptics:
(a) We brought in our DPO for a 30-minute session explaining what data the tool stores, what gets shared with our parent company, and what stays inside our entity. RGPD literacy reduced "this is surveillance" objections by a lot.
(b) We ran a 6-week trial where the data was admin-only and not visible to managers. The team got to see the dashboards themselves first, write their own performance narrative, and only then did managers get read access. The order matters. People accept a mirror before they accept a microscope.
The lesson I keep handing other CEOs: HR tech does not lose to other HR tech. It loses to whatever workflow was already paying off without it. Find that workflow, route it through the tool, and resistance disappears inside a month.
