Problem description:
Maintenance has evolved into a range of increasingly elaborate strategies that rely on vast amounts of data. Many models exist to select among the strategies, but their complexity make them difficult for practitioners to use and therefore they are rarely tested in practice. At the same time, companies collect more and more maintenance data but they do not necessarily know how to leverage it, and even with the right measures chosen there might be difficulties in using them if the data is not of sufficient quality. These challenges are prevalent at Tetra Pak, that collects a lot of data but only analyses a small part of it. 

Purpose:
To propose a maintenance strategy that aligns with Tetra Pak’s maintenance goals, and to determine the necessary changes in the company’s performance measurement practices in order to improve the maintenance process.

Research objectives:
1. Explore what maintenance strategy Tetra Pak should use in its packaging manufacturing plants for the laminator rewinder. 
2. Investigate what performance measurements are required to adopt the selected strategy and whether Tetra Pak is currently collecting that data. 
3. Analyse how Tetra Pak can improve its data quality to successfully implement the selected strategy. 

Methodology:
An embedded single-case study was conducted with a mixed method approach combining qualitative interviews, observations and archival records with a quantitative survey and archival records. The research followed a two-fold approach where a maintenance strategy was first selected and the relevant performance measurements along with their availability and quality were then analysed. 

Findings:
It was concluded that the maintenance strategy most suitable for the laminator rewinder at Tetra Pak is the predictive strategy. The performance measurements relevant to the strategy are maintenance performance indicators, event data and condition monitoring, for which the study found that the availability and quality at Tetra Pak varies greatly. Improvements in data quality were found to be possible through standardisation, more detailed equipment tree classification and language processing of historical data.}},
