This paper reports the results of workshops to improve work at a nursing facility. For service sustainability achieved through work improvements, not only user-centered but also worker-centered design is important. We conducted 17 workshops with care workers for a year to design a work improvement. Though the workers tried to design a solution to create safe aisles between tables where wheelchairs would not hit the tables or chairs, the trial resulted in a failure to implement the solution. A qualitative analysis on the results of a review workshop, which was conducted to analyze why the workshops had failed, revealed that the workers were too cautious to implement the solution, considering not only advantages but also disadvantages such as insufficient preparation. This paper analyzes the reason for the failure from the viewpoint of motivating the workers and making them to feel the values of implementation and includes a discussion on changing the organizational culture of the care worker team.
