How long have some of your permanent vacancies been open? I have worked as a recruiter for many years and have found that some hiring managers are not properly sense-testing why they are hiring. Perhaps that is a sign of naivety, as not all hiring managers are actually experienced in hiring and that is where an experienced recruiter will support them through the process.

Understanding the potential for return on investment (ROI) is important to every business. You will want to be able to forecast the benefit of putting money into something to make an informed judgement on the value of positive outcomes.
