Abstract: Analytic systems provide insights to decision makers based on data. Conclusion quality depends on the input data and the reasoning steps made by analysts during exploration. This paper presents CATS, a system able to: (i) Store and leverage information about analytical processes conducted by analysts; (ii) Improve the quality and confidence on analytical reports, by improving how well analysts recall their activities; (iii) Provide ways of comparing different analytical reports; (iv) Help with the dissemination of best practices within analytical teams; (v) Produce the provenance of analytical reports. The use of CATS is illustrated through an example of tracking the work in WISE (Weather InSights Environment) a real tool that combines forecast and observed environmental data to provide an integrated platform to make informed decisions.
