This document discusses key lean manufacturing concepts - Takt time, cycle time, and lead time. Takt time refers to the rate of production needed to meet customer demand. Cycle time describes how long it takes to complete a specific task from start to finish. Lead time is the total time from receiving an order to delivering an item. Benefits of understanding these concepts include better production planning, reducing overproduction and delays, and improving process flow to meet customer needs.

 Takt time is the rate at which we need to complete a product in order to meet
customer demand.
 In other words it is the production speed to satisfy customer demand.
• If we receive an order of coffee for every 8 Mins.
• That means we need to fill one coffee order every 8 mins to keep up with demand.

 Cycle Time describes how long it takes to complete a specific task from start to
finish.
 It starts from the time when manufacturing is initiated to the time when the
manufacturing is completed.
Example :
• It takes you 8 mins to prepare a coffee order. That is your Cycle Time
• ghiy nfhjpf;f itj;J> rh;f;fiu Nrh;j;J xU fhgpia

Cycle Time - Net Prodn. Time / No. of Units produced

Lead Time
 Mh;lh; vLg;gJ Kjy; nlypthp nra;tJ tiuapyhd nkhj;j fhy msT.
 The total time it takes from receiving an order to delivering an item
(from taking the order to receiving payment).
Lead Time - Total Time from order to delivery
Example :
• It takes 11 mins to serve coffee from the time the customer places an
order (Start to End)
