IT投資の定量的計測

いままでだれかが行っていそうで、行っていなかったミクロでのIT投資導入効果の定量的計測研究について、MITスローンのErik Brynjolfssonが面白い論文を発表しています。

労働保険を扱う保険会社の、渉外担当(CaseMaager)の生産性が、IT投資(EDM,ErectricDocumentManagement)によってどのように改善したかをレポートしてあります。

具体的な評価指標は以下。。。


• Current Year Closure Rate: Measures the percentage of claims closed that were opened in the current calendar year (CY)
• Previous Year Closure Rate: Measures the percentage of claims closed that were opened in years prior to the current CY
• Year to date (YTD) Average Physical Therapy Paid Amount Per Claim: Measures the amount spent per claim on physical therapy costs
• YTD Average Chiropractor Paid Amount Per Claim: Measures the amount spent per claim on chiropractor care costs

• Retention Rate: Measures the case manager retention rate
• YTD Loss Leakage: Measures the total loss payout on the claims. Losses are defined as additional expenses that should not have been incurred on claims if best practices associated with medical management and disability management processes had been properly followed by the case managers

ほとんどの項目で改善効果はあるようです。(当り前ではありますが)
