We are researchers at Charles University in Prague. We have created zIndex as a tool for benchmarking public procurement. You can use it to compare how well institutions manage public money.

No way! How does it work?

Our rating uses hard data about purchase contracts in past three years, with which we calculate 11 indicators covering various aspects of tender practice - for example, the level of competition, or how frequently tenders are cancelled (for details see Documentation). zIndex combines those 11 indicators into a single rating between 0 (worst) and 100 (best).

Sweet, let me see the results!

zIndex does not measure corruption or wasteful behaviour, but a good zIndex score means there is less room for these practices. What we measure is adherence to best practice - as defined by a code of "good behaviour" as defined by OECD, the EU and Transparency International. A bad zIndex result does not necessarily reveal misconduct, but does imply that the buyer has deviated from best practice, which may require an explanation. Every buyer has the opportunity to provide those explanations directly via this website.

zIndex is a non-governmental not-for-profit project, supported by the American Chamber of Commerce's Otakar Motejl Fund, Skanska and Ysoft. The Czech Credit Bureau provides us with our data. All donors committed to refrain from placing content-related conditions on their donations.

Our team

Our mission is to provide the public with a tool that regularly monitors public institutions' procurement procedures. zIndex is still far from presenting a complete image of public procurement practice, but makes a start by bringing key numbers into public debate. By doing so, it aims to motivate further efforts towards real improvement.
