Consider ways to increase the rate of production This will help you determine if the recommendations that you develop later are sufficient to meet your client’s needs.Ģ. Try to quantify an exact number or metric that the client is aiming for.

Are they trying to increase production? Are they trying to improve efficiency? The first step is to determine the specific goals that the client has. There are five major steps to solve a production optimization case.ġ. If your machine is being used to only produce 60 shirts per day, then it is at 60 / 120 = 50% utilization. Therefore, its maximum capacity in a day is 5 shirts per hour * 24 hours = 120 shirts. Utilization represents how much a factory or machine is being used relative to its maximum possible output.Įxample: The machine that your company uses to produce shirts can produce 5 shirts per hour. If the machine runs for 12 hours, then it will produce 60 shirts. The output of production can be calculated by taking the rate of production and multiplying it by time.Įxample: The machine that your company uses to produce shirts can produce 5 shirts per hour. To solve these cases, there are two formulas you should know: What is the best way to achieve this production increase?

Production optimization cases will have you determine how to increase the output or production of a factory or powerplant.Įxample: ExxonMobil is looking to expand its oil and natural gas production by 50% over the next five years. In this article, we’ll cover exactly how to solve each of these types of operations case interviews. Forecasting and capacity planning cases.There are four types of operations cases you may encounter in your consulting interviews: Expect to be working with a lot of numbers and performing a lot of math calculations. Operations cases, also known as operations case study interviews, tend be much more quantitative and numerical than strategy cases. This is especially true if you are interviewing at firms that have a strong operations practice, such as McKinsey, BCG, Bain, Deloitte, Accenture, or Kearney.

This implant established persistence on the victim system by modifying startup registry keys and ultimately functioned as a loader to download additional tools.You should expect to see at least one operations case interview in your upcoming consulting interviews. Later, the actors would download a custom implant via a Base64-encoded PowerShell command. This file would beacon periodically to their C2 servers via SSH, allowing the actors to issue further commands. “In some instances, the actors downloaded a Plink runner named MicrosoftOutLookUpdater.exe. “When they identified vulnerable servers, Phosphorus sought to gain persistence on the target systems,” Microsoft said. Microsoft fixed the vulnerabilities in March. More recently, Phosphorus shifted to scanning for on-premises Exchange Servers vulnerable to CVE-2021-26855, CVE-2021-26857, CVE-2021-26858, and CVE-2021-27065, a constellation of flaws that go under the name ProxyShell. Phosphorus ended up collecting credentials from more than 900 Fortinet servers in the US, Europe, and Israel.

The flaw allowed the hackers to harvest clear-text credentials used to remotely access the servers.

Early this year, Microsoft said, Phosphorus scanned millions of IP addresses in search of FortiOS systems that had yet to install the security fixes for CVE-2018-13379.
