The following paper presents the results of the outcome evaluation of StartBiz; an online tool for start-ups in Switzerland. StartBiz is provided by the State Secretariat for Economic Affairs (SECO) and allows start-ups to enroll with trade registers, VAT, social insurances and accident insurances without any additional fees directly via the internet. The outcome evaluation was required to learn about generated benefits for start-up companies that have used StartBiz so far. At the same time, the evaluation was aimed at providing decision-makers in the SECO with strategic information for their future e-governmental activities (esp. planned expansion of StartBiz to an electronic One-Stop-Shop for small and medium sized enterprises). The paper contributes to the debate of evaluating e-governmental activities by emphasizing an outcome orientation based on the assessment of quantitative benefits. It underlines the advantages but also the disadvantages of such a focus for future outcome evaluations in the field.
