HBR: “Optimal machine learning, overcomes the significant shortcomings in existing supply-chain-planning methods. It has three key components: a decision-support engine, a digital twin, and an end-to-end data architecture.” On digital twin: “A key requirement for the OML decision-support engine to work is a detailed digital representation of the entire supply-chain network, all material flows, and the decision-making processes of all involved parties. By modeling the performance of the supply chain in a highly detailed manner at the granular level of each transaction, the digital twin allows supply chain planners to quantify accurate KPIs for both past and future demand-and-supply scenarios. Such a digital representation has two advantages. First, its calculations of the impact of historical decisions can be compared with the actual results computed by existing business systems, which validates its ability to measure performance accurately and thereby gives management confidence in the system. Second, it can be used to test the effects of alternative supply-chain scenarios or strategies on KPIs. For example, what if the shipment lead times double because of slowdowns in a specific shipping lane? Or how would the disruption of a distribution center affect revenue? Or what would be the best way to reroute shipments to stores served by that distribution center? Together, these two capabilities—historical analysis and predictive power—make it possible for managers to accurately evaluate risk-mitigation strategies, such as alternative sources of supply and transportation, alternative stocking locations, revised production schedules, and the use of product substitutes. As a result, managers can make better decisions.”
James Ball: “I spent weeks asking where, if anywhere, news is discussed and shared on sober terms online. A few diehards of the early internet tried to suggest the resurgence of RSS feeds—automated notifications of new articles on a particular topic on a particular site. They were barely even convincing themselves. The most surprising answer I found—given that it was once considered the villain of the piece—was Reddit. For those who haven’t used it, Reddit is a bulletin-board style social network split into quasi-autonomous “subreddits” focused on different topics. Each of these is managed by volunteer moderators and administrators, who can set and enforce rules of conduct within that community. These subreddits are much smaller than Twitter. The largest—r/worldnews, to use Reddit’s naming format for these threads—comprises around thirty-five million users, of whom around twenty thousand to forty thousand are online at any one time.”
NYTimes: “Economists typically measure productivity as a simple ratio: the total amount of output an economy produces per hour worked by its labor force. On that score, productivity increased 2.7 percent in 2023, according to the Bureau of Labor Statistics, and over the last two quarters has been growing at more than double the rate from 2005 to 2019. On a less technical level, productivity can generally be explained by the old axiom about “doing more with less,” or the folksy virtue of “getting the biggest bang for your buck.” Economists tend to sigh with relief whenever they see a gain in productivity, because it offers a potential win-win for workers, customers and business owners: If businesses can make as much money or more in fewer work hours, then — according to standard economic logic — they can make more per hour, reinvest in operations and pay workers a bit more without sacrificing profitability (or leaning on price increases to push profits higher). As Joseph Brusuelas and Tuan Nguyen, economists at the consulting firm RSM, put it in a note in late January: “The increase in American productivity over the past year, if sustained, is a potential game changer for the economy that represents that mythical rising tide that lifts the living standards of all.””
Economist: “Costco is the world’s third-biggest retailer, behind Walmart and Amazon. Though its sales are less than half of Walmart’s, its return on capital, at nearly 20%, is more than twice as high…Costco stores stock a limited selection of about 3,800 distinct items. Sam’s Club, Walmart’s Costco-like competitor, carries about 7,000. A Walmart superstore has around 120,000. Buying more from fewer suppliers gives the company even greater bargaining heft, lowering prices further. By limiting its range, Costco can better focus on maintaining quality. Less variety in stores helps it use space more efficiently: its sales per square foot are three times that of Walmart. And with fewer products, Costco turns over its wares almost twice as fast as usual for retailers, meaning less capital gets tied up in inventory. It has also expanded its own brand, Kirkland Signature, which now accounts for over a quarter of its sales, well above average for a retailer. Its margins on its own-brand products are about six percentage points higher than for brands such as Hershey or Kellogg’s.”
WSJ: “Generative AI is less suited to quickly building mass audiences—it doesn’t create a platform of users. But it is ideally suited for transforming large organizations by making people and processes radically more productive. “When the social mobile cloud started in 2007, mobile was a big distribution advantage, you could go out and acquire customers, letting them take advantage of the global supply chain and build these full stack companies. AI doesn’t give me any of that. It really is a transformation advantage,” [Hemant] Taneja said. He added, “The bulk of the value is to me about what is the role of AI in transforming both from a vertical standpoint and from a business function standpoint. And most of our energy is looking at how are we going to do that? What is the role of AI in industries like healthcare? What is the role of AI in functions like marketing and customer support?””
