In this paper, we propose the customer-driven evaluation method for the quality of cleaning works. And further, as the case study toward to the introduction of this method, we apply it to the number of Block parks. Firstly, our research was conducted about points visitors to Block parks focus their attention on when they assess the quality of cleaning works, and the result showed that seven items were essentials, i.e."open space","rest room","benches","trees","play equipment","sand pool" and "dust bin". Secondly, 3-level assessment criteria for the quality of cleaning works on each seven item were prepared. In line with criteria prepared, assessments for the quality of cleaning works were conducted. Analyzing results of above assessment, visitors' demanded quality level, and the degree of visitors' satisfaction with current management condition for cleaning work, we examined the evaluation method for the quality of cleaning works in the maintenance of Block parks.
