The case helps understand regression analysis to identify independent variables significantly impacting the tour experience. The CEO of the company is focused on improving the overall customer experience. The CEO has identified six principal determinants (variables) applicable to tour companies’ success. These variables are hotel experience, transportation, cab driver, on-tour support, itinerary planning and pricing.\u0000Multiple regression analysis using Microsoft Excel is conducted on the above determinants (the independent variables) and the overall tour experience (the dependent variable). This analysis would help identify the relationship between the independent and dependent variables and find the variables that significantly impact the dependent variable. This case also helps us appreciate the importance of various parameters that affect the overall customer tour experience and the challenges a tour operator company faces in the current competitive business environment.\u0000\u0000\u0000Complexity academic level\u0000This case is designed for discussion with the undergraduate courses in business management, commerce and tourism management programmes.

Considering the different options of Wine Cooperative of Vidigueira Cuba & Alvito (ACVCA), it is necessary to know the strengths and weaknesses of each option and identify respective opportunities and threats. Additionally, it is important to know the case study object (such as operating specific characteristics, products and management model); the competition; the evolution of the wine sector in Portugal and worldwide; the evolution of the tourism sector in Portugal and worldwide; and new trends in wine and tourism.\u0000\u0000\u0000Case overview/synopsis\u0000In January 2018, Mr Jose, leader of the Board of Directors (BD) of the ACVCA, one of Portugal’s oldest wine cooperatives, located in the south of the country, in the Alentejo region, is preparing the first meeting with the newly elected BD. Addressing the strategy and sustainability for the next term of the BD is mandatory! Mr Jose will have to open the game and lift the veil. Should all their eggs be put in one basket? Or could diversification be the way? Sustainability, in its three pillars (economic, environmental and social), is mandatory, never forgetting that the cooperators want respective income guaranteed. “We can’t risk everything”, thinks Mr Jose! But ACVCA’s affirmation undoubtedly depends on its ability to take risks, to innovate and seek new answers for new audiences! The BD will have to make decisions that lead not only to the affirmation of the brand but also to its renown and to the ACVCA’s sustainable growth. There are several possible options. However, it is necessary to define a path that guarantees the stability achieved, but that allows new markets to be reached and new challenges embraced: increase production capacity, invest in internationalisation, focus on segmentation through innovation, diversification of product or diversification of business area. Wine tourism is a possible way, but how can it be done sustainably and differently? We will have to use creativity and take advantage of our strengths, traditions and customs, intangible and tangible capital and our material and immaterial heritage. It can be done through Amphora wine, produced from its exclusive centuries-old grape varieties. These issues will have to be discussed with all the BD members in the next meeting. Considering the crucial role of cooperatives in the development of the regions where they are located, the success of the strategy is extremely important not only for ACVCA, but also for all its stakeholders. Strategic management decisions in a cooperative always have a double objective: on the one hand, to satisfy the interests of the cooperators and, at the same time, to meet the interests of the market and assert its positioning in an increasingly competitive sector.\u0000\u0000\u0000Complexity academic level\u0000This case study is intended for:▪ undergraduate","PeriodicalId":52298,"journal":{"name":"CASE Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47480338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, four top management and executives were interviewed from the Ministry to gain deeper understanding on the planning of educational and employment reforms being implemented by the Ministry, its implementation and the challenges that the Ministry faced in doing so. Additionally, top management and executives from higher educational institutes in Qatar were also interviewed to attain a more comprehensive understanding of how they worked with the Ministry to implement the educational and employment reforms. The interview participants held key positions within the Ministry and education institutes in Qatar. As a result, they were directly involved in driving strategic decision-making in various areas relating to education at all levels (primary, secondary and tertiary).

Dozee was manufactured by Turtle Shell Technologies Private Limited, cofounded by Mudit and Gaurav.

The cofounders identified the unmet need for a convenient and user-friendly contactless health tracker. Dozee team built a thin sensor-embedded sheet and module that can be placed beneath the mattress to track sleep patterns and health vitals. They also provided data analysis and data interpretation services. After four years of conceptualization, Dozee launched its product and service in 2019. Although the initial response was lukewarm, the onset of the COVID-19 crisis led to significant changes in the health-care industry. Demand for virtual assistance and contactless monitoring devices became increasingly important elements of COVID-19 treatment. Unlike other sensor-based fitness trackers, the sheet could be easily placed under the patient’s bed to capture health vitals. Choosing to pivot from a home-based individual customer segment to a medical-grade device provider for hospitals could significantly increase the scale and scope of the offering for Dozee, but it would also place Dozee in direct competition with other health monitoring devices from different business categories.\u0000\u0000\u0000Complexity academic level\u0000This case is appropriate for MBA and executive-level courses related to entrepreneurship and business model innovation.

The current owners were willing to sell at a lowball offer of $605,000 as the pandemic entered its 13th month. The Gallos felt they needed to act fast to get this deal. However, the risks were extraordinary, as the pandemic had reduced rental income by 50% and borders had just recently closed. The case provides all data needed to compute rental revenues, capital expenditure, operational expenditures and financing costs. Students are expected to compute the NPV and IRR of free cashflows. Students will compute and evaluate the cost of capital using the condo’s projected debt structure, a choice of several proxy betas and a project risk premium. The case also uses extensive sensitivity analysis. This case differs from corporate capital budgeting problems because it evaluates both levered and unlevered cashflows, and the cashflows include savings from personal use.
