From the data presented in the case, the capacity of the individual unit per hour has been
calculated. This value is not uniform. It indicates that there will be lot of idle time for the
staff as well as in the process. It is observed that, in the present system only 48 patients can
be served per day. So it is decided to improve the service capability by applying lean
manufacturing philosophy. At this stage, the total number of relevant clinical staff required
is equal to 5. The idle time for each operation is calculated and shown in Table 3. The total
idle time is calculated as (201600 sec). This idle time must be utilized in order to increase
service capability. The main objectives of applying lean principles are to reduce wastages,
idle time of operators and to increase the production/service capability by combining some
of the operations or adding new ones. These analyses are discussed in the subsequent
sections.
