The aim of this study was to analyse how an IT helpdesk service can be improved in order to align with the organisation’s expectations. The study was conducted as a case study of an IT helpdesk service during spring 2013. The data collection combined a quantitative analysis of event logs data for a two-year period, with a qualitative approach conducting observations and ten interviews. The result showed that the quality issues arose from two main areas; resolution time of requests and professionalism of IT staff. The quality issues are, according to both the quantitative and qualitative analysis, caused by high workload for one of the IT department’s teams and high expectations of the organisation. Furthermore, this study emphasises that alignment between IT department and organisation is an issue of both sides, as alignment concerns mutual understanding and communication. To solve the service quality issues this study recommends starting to work with measurability and continuous improvements, for example Lean Six Sigma. The IT department can strive to increase the interdepartmental communication, share work tasks, educate internally, document competences and clarify responsibilities to decrease the workload.
