New product types are continually being introduced at PlastiPharm as new clients, with their diverse needs, are added to the company's portfolio. The new products are designed by the R&D team and prototyped, often on one of the company's 3D printers. However, when the products are first produced on the production line, a lot of product is scrapped. In a lean environment, which PlastiPharm espouses, why is it important to eliminate the waste?
Eliminating waste requires that quality improves, which increases the company's ability to compete.
In PlastiPharm's Tier 3 weekly report out, it was noted that several product shipments were late. The team brainstormed using a fishbone diagram - looking at people, methods, machines, materials, measurements, and environment. The process helped them determine that there were several factors that played into the shipment delays: a key piece of equipment was down for a day and a half, an illness reduced the number of employees in a department, and defective materials took a day to replace. Which of the following statement best explains why it was a good idea to systematically brainstorm rather than just quickly blame the most likely culprit?
Getting people to provide different insights and knowledge helped identify all the root causes so they could all be addressed.

Involving different departments allows for different ideas and perspectives to be presented as well as a deeper commitment to the outcome from everyone.
PlastiPharm has been on its lean journey for five years, and senior management has fully embraced the lean business methodology. Management requires a minimum number of monthly kaizen bursts, which are to involve all personnel involved in the improvement process. Why is it necessary to have everyone participate in these continuous improvement efforts?
Involving people from all levels of the company helps them to buy into the improvements and aids them in developing a lean mindset.

At PlastiPharm, the extruded film, from which all the medical device bags are created, was purchased from one supplier for many years. The quality of the film was not consistent, with burnt areas or bubbles being the most common defects. Because of a patent, it was not possible to change suppliers. However, the patent recently expired, and PlastiPharm has contracted with a second supplier that has set up cameras to visually inspect the process and identify any defects prior to shipment. Which of the following statements best explains how PlastiPharm solved its variability problem with poor quality raw materials?
Outsourcing to a different supplier that was willing to provide better quality raw materials allowed PlastiPharm to consistently make quality products.
As PlastiPharm's business has expanded, the company has built a new addition and added new equipment. Each machine has the capacity to monitor the heat of the raw materials as they go through the machine - maintaining a temperate of 370 degrees, plus or minus ten degrees. If the temperate fluctuates beyond those parameters, the machine shuts down, and floor technicians address the issue and adjust ensure quality is maintained in the product. In addition, 100 percent of all products are visually inspected for defects. Why does PlastiPharm take such great efforts to ensure its products meet industry standards and customers' needs?
Quality products make the most important contribution to the company's long-term profitability and success.

Value-stream mapping at PlastiPharm is a once-a-year effort that is conducted by senior management at a high level. Because PlastiPharm produces more than 150 products, the value-stream maps are often obsolete before they are posted on the shop floor. The 3D production area has proposed to management that they analyze and create their own value-stream maps for the different products they make. Why is it a good idea for the 3D area to take over this task?
The 3D area understands better than management how they make the products, can best describe the process, and can then identify ways to improve.
If annual demand is 24,000 units, and the order quantity is 3,000 units, which of the following accurately describes the decision-making environment?

A client ordered 1,000 2D medical device bags from PlastiPharm. Unfortunately, delivery was delayed by two days, and the client was not pleased. A bottleneck analysis was conducted to determine where the problems were in the process. Target times in all steps of the process were compared to actual times. Interestingly, the analysis showed that the client did not respond to questions for two days (someone was out sick, and no one covered for them). While the two-day delay was explained, PlastiPharm determined that improvements could be made to avoid such a delay in the future and took steps to ensure there would be multiple people in the client organization with whom they could ask questions. The client was satisfied with the analysis results and appreciated the effort. Why was it important for the company to perform a bottleneck analysis and then take action?
The bottleneck analysis allowed the company to identify the problem, determine a solution so it would not happen in the future, and maintain client satisfaction.
The economic order quantity minimizes ________.
The combined costs of ordering and holding inventory
While training is often the first thing to go in tough economic times (and sometimes is never addressed at some companies), training employees at PlastiPharm always receives high priority. Training focuses on safety, quality, expert equipment operation, and accurately following processes to ensure things are done right the first time. How does the company benefit because of this training approach?
The company benefits from lower costs, higher quality, and less waste.

Training new employees on customer needs and doing the job right the first time promotes an attitude of continuous improvement that leads to successful production processes.
A new business analyst at PlastiPharm, a company that produces medical device plastic bags for safe storage, handling, and transportation of scientific products, was tasked with developing a process design document for a company that needed a new bag for their cell culture process for a new vaccine.

Why was it important for the business analyst to thoroughly understand each aspect of the process?
Understanding the process and documenting it accurately created a foundation for the process and made it more likely to be successful.

When assessing whether product release deadlines were met during the first three months of the year, the quality assurance (QA) team noted that they were late 23 percent of the time. During that time, the team had hired two new specialists. The team immediately assessed their processes, including that of approving lot records, a required step to ensure that each lot met product requirements, which then triggered a product release. They found that the new QA reviewers were slow to make decisions because of lack of experience and knowledge. Which statement best explains why analyzing the lot record process and identifying the major constraint for product release was helpful to the QA director so she could take action to improve?
dentifying the constraint informed the QA director of the need for increased training for the new specialists.
