This thesis for 15 credits were executed at Sala Brand AB in Sala,Sweden. Sala Brand Ab develop, manufacture and install bodywork forfirefighter trucks in the nordic countries. This thesis assumes from a report called “Friska brandmän” or“Healthy Firefighters”, written by Magnusson and Hultman (2014). They visualize a problem regarding the uncertainties of what chemicals firefighters are exposed to. After the report was published some ofthe clients to Sala Brand AB started their work towards betterworking conditions, and how their breathing appliance could be storedoutside the firetruck cabin. The thesis mainly focuses on what needsand demands the customer has regarding storage of the breathingappliance. Sala Brand also has an issue with this new workingstandard, as many of their clients have different needs. Whichresults in high amounts of variation in their manufacturing andincreasing cost as a result. These can be saved if the client makesright choice. The work towards finding customer needs started with designing twoconcepts Sala Brand AB thinks the clients wants, which later wasshowed for the clients during the interviews. Two customers were paida visit, Nerikes Brandkår, Örebro and Räddningstjänsten Dala Mitt.The results from these interviews was then presented in tables withtheir needs and importance for the function of the concept. Later,conclusions were made on the results gathered from the interviews onwhat type of concept the costumers prefer. Then concepts andsolutions were generated to study which concept who satisfied theneeds and properties the costumers expressed. Bergman and Klefsjö(2007) means that quality of a product is based on what the costumersexpect of the product in the first place. The result became a concept developed from an already existingconcept, mainly because it satisfies Sala Brands needs to reduce thevariation in the production. The concept is a box with a liftingconstruction that lifts the breathing appliance up towards an angleof 30-40 degrees to make it easier for the firefighter to put it on.Then on the way home from an accident the breathing appliance can bestored in the same boxes without negatively affecting the firefighters working conditions. The breathing appliance can then,when the firefighters has returned to the fire department, be replaced with a clean one.
