What kind of service would a company want to provide its employees who often work from home, travel, or are otherwise on non-company networks?
A Virtual Private Network (VPN) service should be a basic utility for all employees who may work remotely. Working on an untrusted network such as at a coffee shop, an airport, or even a client's site is increasing the risk for leaking valuable company data or the employee's data. A VPN provides protection by creating a more private and secured data transmission method that makes intercepting information incredibly difficult. It can also allow employees to securely access internal areas of a company's network depending on its configuration.

What is a common way a company who wants to securely segment its network divide systems into different areas?
One of the most common types of network segmentation is between a safer internal network and a "demilitarized zone", or DMZ. Devices that provide outward facing services such as email, web, or DNS, will be placed in the DMZ as they face a higher risk of being attacked due to their exposure. Devices that do not generally provide internet facing services such as employee laptops, internal file shares, etc. can be placed on an internal network. The goal is to prevent malware and malicious actors from having easier access between, for example, a compromised web server and an internal file share.
Just In Time (JIT) was a concept popularized by Toyota for reducing time and costs associated with production. A feature is the minimization of inventory requirements through smaller, scheduled orders. Explain how companies using JIT may have been impacted by the supply chain issues caused by the COVID pandemic and what management teams may be forced to do to combat the situation.
JIT is an excellent strategy when the supply chain for parts used in manufacturing processes is predictable and reliable. A company like Toyota was able to minimize the sizes of inventories needed for their manufacturing which brought costs down and efficiency up. With a supply chain that now features unpredictable shipping times and shifting costs, production can be ground to a halt if a critical component is not immediately available. Companies using JIT who are facing component shortages may need their supply management teams to begin placing larger orders for stages in their production where regular stoppages are occurring due to slow shipments. Building inventory, while defeating part of the benefit of JIT, could allow production to continue which may be a lesser cost than stoppages.
