Delivery schedule achievement
QCD: measuring manufacturing performance, Published by the Department of Trade and Industry in 2004 suggested that Delivery Schedule Achievement (DSA): ‘…measures how well a supplier matches the planned delivery requirement of the customer…. DSA is a function of good plant performance, which in turn is an indication of good management. Good plant performance is demonstrated when production flows through the plant without interruptions.’
DSA measures actual delivery performance against the planned delivery schedule.
- Late and early deliveries are called ‘not on time’
- Deliveries of too many or too few parts and parts that don’t conform to the job are ‘Incorrect quantity deliveries’
Delivery Schedule Achievement (%) = 100 x (planned deliveries - (not on time + incorrect quantities))/planned deliveries.
Deliveries that area not on time and incorrect quantity should only be counted once.
