Inventory is listed as an asset on a firm's balance sheet and consists of the stocks or items needed to maintain production, support activities such as maintenance and repair, and provide customer service. Inventory typically is categorized based on its flow through the production cycle, using such designations as raw materials, work in process, and finished goods. Maintenance, repair, and operating supplies also are stocked to support the functionality of the firm.
For planning and forecasting purposes, inventory is classified based on the source of its demand as either independent or dependent. Independent demand items are requested directly by the customer and thus must be forecasted. Demand for dependent items can be derived or calculated based on relationships to independent items, usually noted by higher levels in the bill of material.

A huddle is an action by a team to strategize, support and motivate one another towards accomplishing or aligning objectives and goals. Huddles are typically held before an activity takes place. Huddles can be held in any area or department of an organization, they do not need specific rooms just a format to conduct the huddle. The main difference between a huddle and a meeting is both how it is conducted and the amount of time the huddle takes compared to a meeting. Huddles can be performed in under 7 minutes.

Obeya or Oobeya refers to a form of project management and is a component of lean manufacturing. Even more specifically, the Toyota Production System. The obeya is a similar concept to a "bridge room" or a "war room."
During the product and process development, all individuals involved in managerial planning meet in Obeya to speed communication and decision-making. This is intended to reduce "departmental thinking" and improve other methods of communication which tend to introduce forms of waste into the process.
Conceptually akin to traditional “war rooms,” an Obeya will contain: visually engaging charts, graphs, milestones, progress, countermeasures and any other forms of critical information for attendees to make decisions accurately and efficiently.

The bullwhip effect can be described as an extreme change in the supply chain upstream that is normally triggered by a small change in demand downstream. This often affects inventory levels which can shift from being on backorder to being in excess of the needed demand. The general cause of these fluctuations within the supply chain is almost always related to communication. As communication travels up the supply chain with various forms of waste and delay amounts, times and the accuracy tend to "whip" further from the actual need. The one sure fire way to eliminate the bullwhip effect is to align supply with demand, including completely transparent communication and synchronization of the supply chain perfectly.
