Using statistics for management decisions Hands-on case study!
The correct way! …but harder Internal AND external buy-in! WHY????????????????
Best when combined - Loans of books are down from 60 000 to 40 000 - Full-text downloads are up from 40 000 to 60 000 - BUT student numbers have halved! - NO! student numbers have doubled! HOW?????????????
Technical University of Atlantis A brand new institution, the collection of monographs has to be built up. An initial fund of A$1,000,000 has been given, and now the library has been asked to explain to the Senate Library Committee how they are going to divide this equitably amongst the different departments…
Per head division Add up all students, divide money by total and multiply result per numbers in each department!!! QED!! Faculty of Engineering: Mechanical16000 Marine80000 Civil230000 Astronautics10000 Quality20000 Faculty of Applied Sciences Marine biology230000 Environmental Science 80000 Horticulture20000 Biotechnology160000 Vulcanology10000
Problem! The Faculty Librarian for Applied Sciences looks at this and says “There’s no way we can have A$230,000 for Marine Biology, but only A$10000 for Vulcanology – you can’t build a collection with only A$ 10000!!
Solution Divide the budget into two: Use half for an equal distribution for departments, and half per student Per deptPer studentTotal Faculty of Engineering: Mechanical50000800058000 Marine500004000090000 Civil50000115000165000 Astronautics50000500055000 Quality500001000060000 Faculty of Applied Sciences Marine biology50000115000165000 Environmental Science500004000090000 Horticulture500001000060000 Biotechnology5000080000130000 Vulcanology50000500055000
Everyone happy! The Faculty Librarian for Engineering clears his throat: This looks fair, but we have been told that as a library we need to support research – and we all know that my Faculty produces most of the research! AND we know that the material used by researchers and students doing research is more expensive! But this doesn’t show it!
Solution Divide the budget into three: Use one-third for an equal distribution for departments, one-third per student, and one third to be divided on the basis of research output and postgraduate students

Now everyone’s happy! Head of Technical Services is still frowning: We’ve taken into account the number of students, research needs and even protected smaller departments, but in my department we know that the price of material varies widely – Vulcanology pays four times as much as Horticulture for their material! Surely this must be taken into account?
Final solution? Divide into quarters: One quarter per department One quarter for students One quarter for research One quarter for cost of items.
