In today’s world, waste is a big
topic, whether it is in work place, community and house hold activities.
Let us understand first what is
waste? Anything which is non value added is waste! Our focus should be more
into how to minimise Non value added activities with value addition, then waste
automatically will reduce.
Typical ratio of Non-value added
and Value added activities are 95%: 5%. In any project, you will see 5% as
value added and 95% non-value added activities. Most of the cases, we only focus on reducing value added
activities, and end up gaining minimal
and nothing , example if you reduce 50% of value added activities, your total
cycle time would be 97.5% ( only 2.5% improvement), mean you improve only 2.5%.
If you reduce 50% of non-value activities, you improved by straightway 47.5%. That
shows your through put and cycle time improvement.
Do we know what the biggest
Non-Value activities are? Anything for waiting
is biggest Non-Value activities, the waiting led into more DOWNTIME…!
