TAMAR states that the output report need only show the overall maturity level rating for the organisation. However, it also states that the report must be in line with the objectives set out at the start of the assessment.
If the objectives of the assessment defined by the Sponsor state that detailed information is required to drive process improvement, more information than just the overall Maturity Level may be required to back up the assessment ratings.

Another form of graph helps to show how well the the organisation has done in comparison with other organisations who have undergone a TMMi assessment, as shown here:
