This paper focuses on the ability to communicate public e-Services, as a part of e-Service development. The purpose is to elaborate on the concept “communicability”, and to define elements and criteria useful in the evaluation and improvement of public e-Services. In terms of public e-Services, communication takes place in a context based on an understanding and relation between the public sector and the citizens using the provider’s e-Service solution. Public sectors are increasing their e-Service offers, making communicating e-Services an important part of the service delivery. The citizens’ ability to find, understand, and use the service is a return on investment. This paper combines a business process and a social interac- tion approach to e-Services. The empirical grounding is a Swedish municipality case study with a pilot evaluation, interviews with developers, and an eye tracking usability test on e- Services with citizens partaking in a university course. The research contributions include a first version of a defined concept of communicability in the e-Service context together with a conceptual basis for evaluation purposes. Findings can be used as a basis for developing an evaluation tool and a handbook to improve communicability in public e-Service solutions.
