Takt time is the rate at which a finished product needs to be completed in order to meet customer demand. If a company has a takt time of five minutes, that means every five minutes a complete product, assembly or machine is produced off the line because on average a customer is buying a finished product every five minutes. The sell rate – every two hours, two days or two weeks – is the takt time.
Takt time can be determined with the formula:
Where
T = Takt time, e.g. [work time between two consecutive units]
Ta = Net time available to work, e.g. [work time per period]
D = Demand (customer demand), e.g. [units required per period]

Kanban is a visual signal that’s used to trigger an action. The word kanban is Japanese. Roughly translated, it means “card you can see.”
At its simplest, kanban is a card with an inventory number that’s attached to a part. Right before the part is installed, the kanban card is detached and sent up the supply chain as a request for another part. A part is only manufactured (or ordered) if there is a kanban card for it. Because all requests for parts are pulled from a customer’s order, kanban is sometimes referred to as a "pull" system.

OEE is an abbreviation for the manufacturing metric Overall Equipment Effectiveness. OEE takes into account the various sub components of the manufacturing process – Availability, Performance and Quality. After the various factors are taken into account the result is expressed as a percentage.
Do not compete with your competitors, compete with perfection.
