Bain Case: Old Winery

Solved 51.2k times
Bain Case: Old Winery You have inherited the “Old Winery” from your grandfather, a winery which has been family owned for five generations and can be dated back to the 16th century. Half of the eleven hectares are used to grow white grapes, the other half to grow red grapes. They are grown in the conventional way, i.e. they are not organically farmed and certified. The vine stocks are in a good condition regarding age and care. Overall, only ¼ of the harvest is made into wine by the winery itself; the rest is sold. Your grandfather never wanted to change the image of the winery and left the managerial and administrative task to a young and energetic wine-maker. Due to the not so well-known brand , the demand for the “Old Winery” wine is currently rather low. You do not intent to run the winery operatively, given your limited knowledge of wine making, but find the idea of owning a winery exciting. Your plan is to give the winery some fresh impetus.

Roland Berger Case: Onlinestar

Solved 34.1k times
Roland Berger Case: Onlinestar Onlinestar, an online retailer of furniture and garden products (core business), has grown significantly in recent years as a result of an expansion of its product portfolio. The company mainly imports goods from Chinese manufacturers but also operates its own production of cat lavatories (special business) in Eastern Europe. The company sells its goods via Amazon and ebay, and recently via an online shop on its website. Despite this development, the financial ratios have deteriorated in recent years. In particular, gross profit margin decreased significantly. Combined with a significant increase in shipping costs, this led to a negative result for the first time in the recently ended fiscal year and a resulting strained financial situation. Against the background of expected stagnating sales for the current financial year, short-term action is required. The board of Onlinestar asks you for an analysis of the reasons for the negative result as well as a derived recommendation for action. As a consultant, you should bring in your knowledge in online trading and develop solutions. In addition, the management board would like to receive a sales and gross profit plan from you for the current financial year.

DB MC Case: Einstieg in das internationale Fernbusgeschäft

Solved 4.9k times
DB MC Case: Einstieg in das internationale Fernbusgeschäft Für Unternehmen ergeben sich durch die Digitalisierung neue Chancen und Risiken. Neue Märkte mit großem Potenzial können erschlossen werden – gleichzeitig erhöhen Wettbewerber den Konkurrenzdruck. KMUs, Start-ups und Konzerne bringen unterschiedliche Kompetenzen und finanzielle Möglichkeiten mit. Erst vor wenigen Jahren ist ein Start-up mit Know-how im Online-Vertrieb nach der Änderung des Personenbeförderungsgesetzes in den deutschen Fernbusmarkt eingetreten, welches schnell ein großes Netzwerk an Subunternehmen aufgebaut und damit große Marktanteile gewonnen hat. Dies hatte erheblichen Einfluss auf das Kerngeschäft der Deutschen Bahn. Mit dem Ziel Synergien zu nutzen und die Bedürfnisse des Kunden ganzheitlich zu erfüllen, konzentriert sich die Deutsche Bahn nicht allein auf ihre bisherigen Geschäftsmodelle, sondern kooperiert mit anderen „Mobility-Unternehmen“. Von Ihrem Kunden aus dem Topmanagement wurden Sie als Consultant von DB Management Consulting beauftragt, einen Business Case zu bewerten und zu prüfen, ob die Deutsche Bahn ihr bisheriges Geschäftsmodell öffnen sollte, um durch die Kooperation mit einem etablierten mittelständischen Busunternehmen in das internationale Fernbusgeschäft einzusteigen. Die Deutsche Bahn bietet bereits wenige internationale Verbindungen der Marke „IC Bus“ an, jedoch hat die DB-Tochter in der Vergangenheit große Marktanteile verloren. Im Rahmen der Einführung soll dem Kunden zunächst die Verbindung Hamburg – Lund (Schweden) ohne Zwischenstopp in 7 Stunden angeboten werden. Die Distanz zwischen Lund und Hamburg liegt bei 385 km. Bei erfolgreichem Start ist ein schnelles Roll-out auf andere internationale sowie deutschlandweite Strecken geplant. Im Fokus stehen die Erhöhung des Marktanteils, die Bewertung der Nachfrage des Kunden, der Kosten und Erlöse sowie das prognostizierbare Wachstum im Fernbusmarkt.
