Methods to Analyze Services Portfolio Cost Drivers and Efficiencies




Introduction: This presentation provides a statistical methodology used to evaluate the “health” of a services portfolio through performance data analysis and cost analysis, with the goal to identify cost drivers and efficiencies for performance improvement.
Background: Managing a Federal government portfolio is a complex endeavor. Portfolio Managers have a major responsibility to evaluate whether their portfolio is operating efficiently and effectively. Thus, they need to use analytical procedures that, when executed, will evaluate the “health” of the portfolio and identify areas for increased efficiency and effectiveness. If the analysis is not data-driven, this leads to a lack of proper business case analysis and cost benefit analysis to weed out bad actors in the portfolio.

Methodology: The portfolio managers need to validate the portfolio – review the data in the portfolio, including identifying resources not captured in the portfolio, but should be, and assess the portfolio – take a deep dive into the portfolio prices and fees paid, benchmarking other services, and looking at trade-offs of functions. The robustness of the analysis must be strong enough to indicate efficiencies to the portfolio to include resource levels, skill sets, portfolio standards, service level categories and the overall use of the services. This presentation addresses accepted methodologies which can be can be utilized. It, also, shows how analytical techniques must be tailored to the type and amount of data available.

The methodology selected provided a comparative analysis to include a “within” assessment of the total portfolio data and a “between” assessments of the major cost driving services. Analytical techniques included, but were not limited to, descriptive data statistics, scatter plotting, bar graphs and pie charts. Descriptive data statistics would point out cost driver scaling. Scatter plotting would indicate data consistency by illustrating rate distributions and rates outside the statistical limits, and special effects on contract cost, and outlier population. Bar graphs were used to introduce commonality in rates to include labor category labor rate comparisons, labor and contract utilization across the portfolio, and the effects of a representative skill mix. Pie charts illustrated various distribution percentages across the portfolio.

Results: With these methodologies, the Portfolio Manager was able to determine the service rate statistical ranges and outliers, benchmarked fees throughout the portfolio, compare Prime and Subcontractor rates and the overall Subcontractor effect on the cost of the contract; and compare utilization rates to contracted rates as a performance indicator.
