    The assessment is free of charge and takes 30-40 minutes. We will send you a custom-built report, which will provide a set of maturity scores based on the NextWave Digital Maturity expert model and which will also include a set of recommendations and next steps.

    We will be happy to offer a post-survey review and walk through with you to better understand your assessment report findings, comparisons to market and the associated recommendations.
