Tanja Sliskovic

I help organizations turn people data into clear decisions that improve culture, engagement, and organizational effectiveness.

With 15+ years of experience advising executives across global companies, international organizations, and governments, I work at the intersection of analytics, behavior, and organizational reality, helping leaders understand what is happening in their workforce and advising on what to do about it.

My work typically includes:

•Organizational design and functional reviews

•Employee listening and culture diagnostics (engagement, inclusion, pulse)

•People analytics, dashboards, and data storytelling

•DEI strategy and gender equality frameworks

•Capacity and skills gap analysis

•Change management and leadership workshops

I design and lead mixed-methods diagnostics combining surveys, interviews, desk reviews, and workshops, and translate findings into practical, actionable recommendations. I work closely with leadership teams to ensure insights lead to decisions and not just reports.

Companies and clients I have worked with include Zalando (15,000+ employees), UN Women, UNICEF, USAID, among others. My work has delivered measurable outcomes, including +10 percentage point increases in engagement, 20%+ improvements in team health, and organization-wide adoption of inclusion strategies.

I bring an unique combination of analytical depth and practical application. I have a PhD in Organizational Behavior, advanced expertise in measurement and behavioral science, and the ability to translate complex data into clear, credible action plans that leaders trust and act on.
