VH1, MTV, and LOGO were all popular television channels owned by the ViacomCBS television network. One of the most successful shows on LOGO was RuPaul's Drag Race, a reality television show featuring drag queens. ViacomCBS was considering moving RuPaul's Drag Race off LOGO to a different platform within the ViacomCBS portfolio in 2017. Before deciding where RuPaul's Drag Race would air, ViacomCBS needed to determine whether the show could be successful on another platform given its current fan base, how the potential move would affect the show's ratings, and whether the positioning or targeting strategy for the series would need to change if it were moved.

The appendix of the note contains R code for all of these topics.

This note provides an overview of linear regression for an introductory data science course. It begins with a discussion of correlation, and explains why correlation does not necessarily imply causation. The note then describes the method of least squares , and how to interpret the r-squared and model coefficient values of a simple linear regression model. Next, the note describes how the interpretation of a model coefficient changes when there are multiple independent variables in the model. Finally, the note explains how to interpret the coefficients on dummy variables in a regression model. The appendix includes R code for implementing all of these topics.

This note provides an introduction to machine learning for an introductory data science course. The note begins with a description of supervised, unsupervised, and reinforcement learning. Then, the note provides a brief explanation of the difference between traditional statistical modeling and machine learning. Next, the note covers two models used for classification, logistic regression and decision trees. After introducing these two models, the note explains how train, validation, and holdout sets (and k-fold cross validation) are used to tune and evaluate different models. Finally, the note concludes with a discussion of different performance metrics (ROC cruves, confusion matrices, log loss) that are used to evaluate classification models.

In mid-January 2022, Nadine Hachach-Haram, founder and CEO of Proximie, was thinking about the company's growth plans. Launched in 2016, Proximie was a platform that enabled clinicians, proctors, and medical device company personnel to be virtually present in operating rooms (OR) where they would use mixed reality and a suite of digital audio and visual tools to communicate with, mentor, assist, and observe those performing procedures. The goal was to improve patient outcomes. The company had grown quickly, opening offices in Beirut, London, and Boston, and had 135 employees. Proximie's technology had been used in tens of thousands of procedures in over 50 countries and 500 hospitals. It had raised close to $50 million in equity financing and was now entering strategic partnerships to broaden its reach. In deploying its platform, Proximie also digitized and structured formerly uncaptured data from ORs, making it possible to build a novel database of rich surgical data and prepare an infrastructure for both analytics and for curating insights from users. Hachach-Haram aspired for Proximie to become a platform that powered every OR in the world. To achieve these goals, Hachach-Haram had to navigate several challenges as she scaled the company. She needed to carefully think about the company's partnership and data strategies. Which formula would position the company best for the next stage of growth?

Reymund (ER) Rollan and Shivapratim (Shiv) Choudhury, founders of the digital technology platform GrowSari, were at a crossroads. The feedback from their initial product roll-out were not what they had expected, and they needed to decide how to proceed. The pair, alongside co-founders Andrzej Ogonowski and Siddhartha Kongara, had started GrowSari after they had each spent significant time working at the intersection of technology and Fast-Moving Consumer Goods (FMCG). They were trying to bring data and technology to inform how multinational consumer goods companies sold their products through small, informal retailers known as "sari-sari" stores in the Philippines. These stores, whose name means "variety" or "everything" in Filipino, were a typical convenience store or bodega, selling consumer products from sachets of shampoo to cans of baked beans and potato chips and soda.

Case supplement for HBS Case No. 322-036. Reymund (ER) Rollan and Shivapratim (Shiv) Choudhury, founders of the digital technology platform GrowSari, were at a crossroads.

The Miami metropolitan area is a global epicenter of climate risk from heat and sea level rise, but leaders have only recently mobilized for action to respond to this systemic challenge. Resilient 305 began a collaboration across officials in the cities of Miami and Miami Beach and Miami-Dade County, with some community leaders, but action has been slow. The case identifies the actions and concerns of (a) public sector officials (Mayors and new Chief Resilience Officers), concerned with infrastructure; (b) community activists (grass roots advocacy organizations) concerned with immediate resident issues like electric utility bills in a region with large income disparities; and (c) business leaders (real estate developers and climate technology entrepreneurs) who seek growth and economic returns. Can their interests be aligned, and new collaborations forged to accelerate climate action for both short-term and longer-term goals?

This background Note introduces the implications of climate change (global warming) for American cities. In the U.S., partisan political divides and unaddressed economic and racial disparities in climate vulnerabilities can inhibit action. The two main fronts for action are mitigation (reducing emissions) and adaptation (preparing for change by building resilience). The Note reviews main sources of emissions - energy, buildings, transportation, waste - and examples of mitigation actions, showing differential costs and impact. Adaptation actions depend on geographic location and specific climate hazards, with resilience of infrastructure and institutions a major factor. The most risk-prone are often the least prepared. Crises tend to propel action, and foundations have facilitated adaptation capacity, but leadership challenges require cross-sector goal-setting and collaboration.

Interface has been a leading innovator in the carpet industry, specializing in the manufacturing of carpet tiles for commercial flooring. This case describes the history, context, and technology behind the company's development of its newest sustainable innovation-carbon negative carpet tiles. Interface began pursuing a path of bold sustainable initiatives in 1994 when Founder and CEO Ray Anderson, confronted by an employee, had a realization of the company's negative environmental impact. The company then began moving toward a carbon neutral future, through carpet recycling and leasing programs, transparent emissions reporting and new carbon storing materials. This case uses Interface's story to: explore the context and motivations for companies pursuing environmental goals such as carbon negativity; present the transparency and reporting dynamics within the realm of carbon accounting; and contemplate the stakeholder dynamics created by these decisions. The primary dilemma is whether Interface made the correct decision in launching its carbon negative carpet tiles, given these different factors.

Makena Wanjiru, chair of Kiri Mount Kenya Conservation Network and Resource Centre (Kiri), wondered whether turning Kiri's loans business into a co-operative bank would be in the group's best interest. The challenge was to convince the rest of the board members of the idea. The board of directors would meet on July 18, 2019. Wanjiru had to draft a report before then explaining how the idea was consistent with the group's current strategy and would benefit Kiri for years to come. Wanjiru also needed to consider strategies to grow Kiri's agribusiness beyond the Mount Kenya community.

The case is set in 2022 when Creative Chocolates, a popular United States based chocolate manufacturer, plans to enter the African market. Known in the United States for its unique "warm freshbaked" chocolates, Creative Chocolates expanded to over 100 countries with 26,000 outlets worldwide since its inception in the late 1980s. However, all their outlets were either their own stores or franchisees. Attracted by the market research data on the population growth and economic success of Nigeria and other African countries, Alan Rickman, the new chief executive officer of Creative Chocolates, plans a growth strategy based on penetrating the African market. The case presents Rickman's dilemma-whether to conduct test marketing or not-and builds on it to discuss his next step.

In December 2021, more than a decade after its founding, Goldman Sachs's 10,000 Small Businesses program was still going strong - and the firm now needed to evaluate potential program modifications to reach a wider group of small business owners. Launched in the aftermath of the Global Financial Crisis, 10,000 Small Businesses provided business education, a wide network, and access to capital to U.S. small business owners through more than a dozen city- and state-based program and a National Cohort model. By 2020, Goldman Sachs achieved its goal of graduating 10,000 small business owners from the program, and the firm decided to renew the program with the goal of reaching another 10,000. Against the backdrop of the COVID-19 pandemic, which placed unprecedented strain on small business owners across the U.S., the 10,000 Small Businesses program office team expanded the program's efforts to organize a collective voice for small business owners in U.S. politics, support an internship program that paired community college students with local small businesses, and admit owners of smaller businesses than had previously been accepted into the program. In late 2021, the team considered how to approach its latest effort: supporting Black women business owners in line with the firm's broader One Million Black Women initiative. As 10,000 Small Businesses expanded its reach to smaller businesses and sole proprietors, what modifications did the team need to make? In what ways did Goldman Sachs need to rethink its work to render its One Million Black Women initiative effective?

The South Korean K-pop band, BTS, is shattering linguistic boundaries and reshaping the global music industry. BTS became the first band in Billboard history to simultaneously top the Billboard Artist 100, Billboard Hot 100, and Billboard 200; and the sixth act to have four Billboard Hot 100 No. 1 singles in less than a year. A critical component of BTS's success has been the efforts of a vast network of very dedicated fans called the ARMY. How did BTS build and grow its devoted global fanbase? Could other artists or even businesses follow BTS's lead?

Beijing's Palace Museum was facing the threat of becoming irrelevant and obsolete. A former imperial palace, it housed thousands of priceless cultural relics of historical importance and was once a destination in high demand. However, over time, the museum found its popularity with modern youth was waning. To address this problem, the Palace Museum chose to follow in the footsteps of other global museums and in 1998, launched a digital transformation. By June 2020, the museum had made steady progress in its digitalization over the previous two decades. It formed partnerships with online media platforms and experimented with innovative technology in key areas of its systems and structures. However, this transformation did not come without criticism. Was the museum sacrificing its integrity and its cultural import by leaning too heavily on science and technology? If people could access the collections online, would anyone still bother to visit? The museum was challenged to weigh the risks and benefits of digital transformation.

In 2016, Pythagoras Global Fund (Pythagoras), based in the United Kingdom, decided to launch a fund focused on emerging markets, especially those in Brazil, Russia, India, and China (BRIC countries). Pythagoras's fund manager favoured investing in family-owned businesses, but the investment opportunities in India used ownership structures different than those used in developed markets. The structures in Indian groups altered the cash flow and effective ownership rights in the subsidiary firms, which had ramifications for stakeholders and raised associated governance issues. The fund manager needed to decide which firm to choose by assessing the investment opportunities and evaluating the corporate governance of the companies.
