In another interview question, we discussed how a pull system is considered by some to be superior to a push system in production. Likewise, managing a pull system isn't possible without keeping a continuous flow of work going. It is important that an industrial engineer knows how to manage these big threes of the production system since they ensure that product comes off the end of the line as often as it should "“ which in turn, maintains optimal product flows and the pull system.
Takt time is sometimes called the heartbeat of production in a lean production system so you will need to understand it and know the formula behind it in an interview. The same goes for cycle time and lead time, as both are important to manage production flows and forecasting requirements.

"Takt time is a customer demand calculation. It is defined as the production rate needed to finish an item and meet demand. For instance, if you receive a new order for a product every six hours, then the team needs to complete a product in six hours or under to meet customer requirements (orders). If a product takes longer to build than it's Takt time, something must change, such as design, buffers, manpower, technology or tools used, etc. That's where industrial engineering solutions come in. To calculate Takt time, you need to divide the Total Available Production Time by Average Customer Demand. Cycle time is the sum of the elapsed time it takes to transfer a unit of work from the start until the finish of a physical process. It is defined by the customer and the firm. Lead time, which is an essential part of the planning process, is defined as the time it takes to prepare and produce material and ship it to the customer. In other words, it is the initiation to completion of material in a production process."
