Methodology Flow Chart


This index came about because many people—defence leaders, defence officials and members of civil society—repeatedly asked us: ‘how can we measure our progress in combating corruption in this sector?’ This index assesses and compares levels of corruption risk and vulnerability across countries to increase understanding of the problem and encourage reform. The methodology ensures that we can compare results over time and between countries to monitor progress and encourage change.

Each country is placed in a band from A to F. These bands are based on scores on an assessment consisting of 77 questions—for each question, the government was scored from 0-4. The percentage of marks overall determined which band the government was placed in. Countries were also scored in five risk areas: Political risk, Financial risk, Personnel risk, Operations risk, and Procurement Risk.

We considered a range of institutions in each country:  the defence and security ministries and armed forces in each country, of course, but also any other government institutions with the potential to influence levels of corruption risk in the sector.

Researchers assessed each government individually, using a questionnaire of 77 questions based on our defence corruption risks typology. Each country assessment was peer reviewed twice. We also invited the governments to review the drafts. Where governments responded late, we invited them to submit a report in response instead. Lastly we invited TI National Chapters to undertake a review.

Ultimate ownership and responsibility for the finalised scores and bands rests with Transparency International UK's Defence and Security Programme (TI-DSP).
