Asked and AnsweredBy John W. Olmstead, MBA, Ph.D, CMCQ. I am a partner in a small estate planning/administration law firm in Louisville, Kentucky. We are having a hard time getting a handle on determining the productivity of our associates and paralegals. Many of our associates and paralegals work part-time and the typical metrics such as 1500-1700 annual billable hours, etc. don't work for us. Do you have any thoughts or suggestions?A. You might want to consider using a billable/worked ratio which is the ratio of billable hours logged to hours worked. For attorneys and paralegals that are totally focused on providing client services a good benchmark is 70%-73%. If an attorney or paralegal works 30 hours a week - you would hope to see 21-22 hours billable per week. Based on 50 weeks per year this would equate to somewhere around 1050 billable hours per year. For a full-timer working 8 hours a day or 40 hours per week - 50 weeks per year this would work out to around 1400+ hours per year. Most full-time attorneys work closer to 50+ hours a week and are expected to log between 1500-1700+ hours per year. The expectation for full time paralegals is around 1400 hours.The 70-73% ratio is ambitious - but is achievable. For paralegals this goal will not be possible if they are loaded down with administrative duties. Excellent time management and time keeping skills and practices will need to be in place as well.
