Utvärdering av mjukvara inom processindustrin
This study is an evaluation of the runtime watch function in a OEE software, knownas ProTAK. OEE stands for Overall Equipment Effectiveness, it?s a way to measurethe factories process efficiency. The runtimewatch function allows the user to setup and monitor certain critical objects that are of importance for the pulp and paper process at the mill. The data from the runtimewatch can be correlated towards the suppliers specification for the components. The function can if beeing used correctly result in a higher timeavailablity utilization rate for the factories which in turn results in a higher profit margin for the companies. It turns out that the function is used to a limited extent by the customers and the study intends to find out the reasons behind this and to proposeimprovement suggestions to increase the utilization rate. The design of the study was based on the scientific theory of user evaluation in which three suitible evaluation methods were selected. The three methods that were used were the webbsurvey, the observationstudy and the focusgroup.The end result showed that the function was appreciated by the customer but needed to be strengthened in certain areas. ProTAK Systems AB needs to develop its marketing of new features and educate the customer, but also improve/clarify certain critical usersteps in the graphical user interface. The study shows that the user lacks support, assistance, training and information on how the function can be best used on their factory. A plan with improvement proposals was developed in correlation with the developer and it?s hoped that the results of the study can serve as a basic template when other features of the software are evaluated for building the next major iteration of ProTAK.
