Predictive Enrollment Engineering™ is authored and maintained by Alen Hadzic, founder of the methodology and CEO of Clinical Trial Scan™. The site is an educational and reference resource for clinical research professionals: sponsors, contract research organizations, site networks, and principal investigators. It is not a storefront — there is nothing to purchase and no account to create. Correspondence is handled directly by the author rather than a support desk, so replies are considered rather than immediate.
What to write about
- Questions about the framework: funnel modeling, probability-based forecasting, conversion measurement, participant psychology and retention.
- Corrections or clarifications to published articles — include the article title and the passage in question.
- Citation and reuse requests for academic papers, conference presentations, or industry publications.
- Speaking, writing, peer-review, and podcast invitations relating to enrollment methodology.
- Applied enrollment modeling for a specific protocol — handled by the Clinical Trial Scan™ team, not this reference site.

Before you write
Most methodology questions are already answered in The Framework or the Articles & Insights library. Benchmark figures, cost-per-enrollment models, and protocol-level forecasts are not published on this site and are not shared by request; the reasoning behind those numbers is explained openly, the numbers themselves are not.
