Why Benchmarking Matters in 2024

Over the past several years, we have seen enormous growth in the pharma industry. Many companies outsource their clinical development programs to CROs, but finding the right fit — and ensuring they can meet expectations—is a time-consuming, labor-intensive task better outsourced to experts. ISR’s annual report is a reliable resource that takes the guesswork and stress out of the process, enabling companies to make decisions informed by data and independent performance evaluation.
