Abstract
The goal with this master thesis is to examine the usability in the Tetra PlantMaster. Tetra PlantMaster is the control system for the dairies that Tetra Pak develops.
Tetra PlantMaster is the system which the operator uses in order to govern the entire process when raw milk becomes a product ready to be delivered to the grocery stores. This includes applications to produce soured milk, yoghurt, icecream and numerous other dairy products.
The idea behind Tetra PlantMaster is that one or a few operators are supposed to run and control the entire process from when the raw milk arrives at the dairy to the point when the finished product leaves the plant. In order for a few operators to maintain the entire plant it, is crucial that they can... (More)

Tetra PlantMaster is the system which the operator uses in order to govern the entire process when raw milk becomes a product ready to be delivered to the grocery stores. This includes applications to produce soured milk, yoghurt, icecream and numerous other dairy products.
The idea behind Tetra PlantMaster is that one or a few operators are supposed to run and control the entire process from when the raw milk arrives at the dairy to the point when the finished product leaves the plant. In order for a few operators to maintain the entire plant it, is crucial that they can absorb much information from all parts of the process in a very effective way and that all adjustments can be done in an
available and effective way.
In order to examine if that is the case, a study in mainly three parts have been made. The needs of the operators have been surveyed and compared with Tetra Pak internal guidelines on usability and a thorough investigation of the technical literature on the subject.
Through interviews with the operators in connection with a visit on a dairy, interviews with engineers that have big customer contact and questionnaires to Design Owners, the needs and wants of the operators have been surveyed. Several different document concerning Tetra Pak internal guidelines have been studied and technical literatures have been studied in order to understand what good usability really is.
These three parts have been compared in order to analyze how good Tetra
PlantMaster is in comparison to prevailing scientific theories. In order to be able to compare the different part in a good way an analytical tool called GOMS have been used.
The result is a point out regarding the weaknesses of Tetra PlantMaster and a number of recommendations on how to prevent these weaknesses. (Less)
