Reiss R and R

...Defining customers as those people and organizations for whom R&R creates value, R&R serves the following customers: 1. TV Guide; 2. American board game players, i.e. adults and children; 3. Retail outlets, which can be classified as mass merchandisers and department/gift stores; 4. The game developer, i.e. ‘a professional inventor’; 5. TV guide employees who develop the questions; 6. Sam Kaplan; 7. Sales representatives; 8. Kaplan’s supplier; 9. Swiss Colony; 10. Heller Factoring. Arguably, TV guide is a supplier/ marketing channel/ licensor, yet R&R creates value for TV Guide in the sense of creating a business opportunity. A similar argument holds for the other customers of R&R as well. If we look at the final consumers of the product, then according to the definition of Osterwalder and Pigneur, R&R serves a mass market. Taking into consideration the remarks of Mr. Reiss, who mentions that his customers are the manufacturers representatives and the buyers of major chains, we can argue that he distinguishes between input and output in his firm. Thus making the business model multi sided, the suppliers need many retail outlets to have their products for sale; and vice versa: the retail outlets require large production. The value proposition describes what value is delivered to the customer. Or, to be more precise, what are the bundles of products and services that create value for R&Rs customers. Given the limited space of 1 page, I will stick to the customers defined by......

MAHLICHa and THOMAS ROEDIGER-SCHLUGAb, Economic Policy Department, Austrian Federal Economic Chamber, Wiedner Hauptstrasse 63, A-1045 Vienna, Austria. b Department of Technology Policy, ARC systems research, Donau-City-Strasse 1, A-1220 Vienna, Austria. Author for correspondence. E-mail: thomas.roediger@arcs.ac.at a Abstract. During the past 20 years, the world pharmaceutical industry has experienced a dramatic increase in R&D intensity. We apply and extend a model developed by Grabowski and Vernon (2000, Journal of Evolutionary Economics, 10, 201–215) with a pooled data sample of the 15 publicly listed Japanese drug firms for the period 1987– 1998. As in the original study, we find expected returns to be an important determinant of R&D spending in the Japanese drug industry, albeit considerably smaller than in the U.S., which is particularly obvious in the case of returns from newly introduced drugs. However, our results are sensitive to econometric model specification, in particular to controlling for serial correlation and to a dynamic specification of the baseline model. Likewise, estimates on financial constraints are sensitive to model specification, indicating that Japanese drug firms face small or no financial constraints. Our results are consistent with the general literature on R&D investment behaviour, yet raise some methodological questions......

R&R Case

...Analysis of the Case R&R Bob Reiss was an entrepreneur. He saw an opportunity in the market to make a profit and he succeeded. The following describes his market transactions and whether they were right or wrong using transaction cost economics theories. I will use Oliver Williamson’s theories and rules to decide whether the transactions were correct. At the end I will have enough information to decide if every opportunity needs a firm and if there is room for entrepreneurs who depend on the price mechanism. Reiss’s first major market transaction was designing the game. He took this to the market and found a professional inventor, whom he knew. This was the right decision. This game only needed to be designed once. The frequency was low. Therefore there was no point in wasting time and incurring the costs of creating it. Also this product was unique. He would not have been able to create it as simply as the market, which had more experience. Since Reiss knew the designer the uncertainty of him defaulting on the contract was very low. He also knew that the designer would be motivated to complete the project because he aligned their interests together through a sales motivated contract. Next was Reiss’s responsibility to set up operations to take the game to market. He didn’t have the cash flow to do this. Instead of raising the money himself he established a partnership to create the firm Trivia Inc and went to the market to gain the funding. His......

R&R Case

...Harvard Business School 9-386-019 Rev. November 15, 1987 R&R During the summer of 1983, Bob Reiss observed with interest the success in the Canadian market of a new board game called “Trivial Pursuit.” His years of experience selling games in the U.S. had taught him a rough rule of thumb: the sales of a game in the U.S. tended to be approximately ten times those of sales in Canada. Since “Trivial Pursuit” had sold 100,000 copies north of the border, Reiss thought that trivia games might soon boom in the U.S., and that this might represent a profitable opportunity for him. Reiss’ Background After his graduation from Harvard Business School in 1956, Reiss began working for a company that made stationery products. His main responsibility was to build a personalized pencil division, and he suggested that he be paid a low salary and a high sales commission. He was able to gain an excellent understanding of that market, and by 1959 could start on his own as an independent manufacturer’s representative in the same industry. His direct contact with stores that sold stationery products revealed that many of them were beginning to sell adult games. He decided to specialize in those products. In 1973, Reiss sold his representative business to a small American Stock Exchange company in the needlecraft business in exchange for shares. He then set up a game manufacturing division and ran it for that company, building sales to $12,000,000 in three years. Reiss decided to go into...

R&R Case

...R&R Case Write UP By: XXXXXXXXX Bob Reiss is an experienced player in the Toy/Game market. Currently he is deciding how to follow his successful TV Guide trivia game. He could try to create a spinoff of the TV guide game. He could launch a new proposed trivia game called Whoozit, where you guess people based on clues. Mr. Reiss has to make a decision launch Whoozit, a new trivia game, or try to spin off the TV Guide game. My recommendation is to launch Whoozit. The Whoozit game allows Trivia Inc. to leverage their skills developed in the launch of the TV guide game. Trivia Inc. has access to the channels, the manufacturers, and the pulse of the trivia market customer. The case indicates that Trivia Inc. had a preliminary royalty deal with the Bettman Archive, keeper of the images necessary for Whoozit. I think the addition of a magazine like People, Life, or Time would create a direct point of touch/access and lend more recognition to the endorsement. Another reason to launch Whoozit is the low cost of the endeavor. If analogous estimation holds true, Trivia Inc. could produce these units for about $5/unit and stand to make profits of about $2.00 per unit on 500,000 units. The total cost to launch The TV trivia game was $50K, but profits were over $2M net for Trivia Inc. If Whoozit could be executed as successfully as TV Guide TV game, it would be money well spent. Finally, the lessons that Reiss had gleaned from Trivial Pursuit’s US launch are......

R in Brics

...The ‘R’ in BRICs: is Russia an emerging power? S. NEIL MACFARLANE * The notion of emerging powers presupposes a number of characteristics shared by the states in question.1 These include regional preponderance, aspiration to a global role, and the contesting of US hegemony. These characteristics arguably make the group as a whole a useful category in analysis and policy formulation. In particular, cooperation among these states, and possibly with more established powers seemingly equally unhappy with the unipolar configuration of international politics (e.g. France), may create a basis for a coalition having the potential to balance American power.2 There is ample evidence from all of the emerging powers of unhappiness with the existing structure of international politics. There has also been substantial consideration of the potential for cooperation among them and with certain European states to constrain the hegemon—from the suggestion of entente between France, Germany and Russia to the repeated examination of prospects for a SinoRussian–Indian triangle, and the growing Chinese and Russian interest in bilateral cooperation over shared security concerns.3 This article assesses the role of Russia as an ‘emerging power’. How do Russians interpret the international system in which they operate? What kind of system would they prefer? What are they trying to do in the current system and why? How do these considerations affect their relations with the hegemon, with other......

...advertising platform like TV Guide represented. 3. Would this approach have worked for Parker Bros., or Milton Bradley? The approach of Reiss was to minimize fixed costs and risk, by externalizing many of its game production and marketing functions. This approach would have not worked so well for larger corporations such as Parker Bros or Milton Bradley, with an already stablished large structure and already incurring in higher fixed costs ($250,000 for design and $1M for advertising). 4. How successful (financially) was Reiss? Why was he successful? Reiss achieved a net profit of $2.75M for its joint venture with Kaplan, departing from an initial expenditure of $50,000. In addition to that, he obtained about another million ($0.94M) by means of R&R’s negotiated commissions (See approximate calculations on annex). Reiss venture was an example of financial success. He managed to obtain a huge ROI, whilst provided benefits to other parties, without having to risk big amounts of own capital, by finding the resources and putting them together. 5. As a result of this success, what should Reiss do now? Reiss should take into consideration trivia-games decline and retailer reluctance to place this product on their stores. To overcome these new obstacles, Reis should keep the relationship with TV Guide and should leverage the previous exit of TV GAME, by marketing WHOOZIT as its continuation, but differentiating it as a product lighter and easier for all audiences.

R&R Case Study

...Bob Reiss was a passionate entrepreneur with a strong background in the gaming industry. He was very successful with his new game venture with sales of $12,000,000 in three years. Once successful, Reiss decided to continue in this space and started his own business under the name of R&R. The toy and game industry was an established market with a very short lifecycle, frequently of no more than two years. Based on the case, I think Bob did the following things right which made him highly successful with his Trivia game: What did he do right? 1. Market awareness- He was an experienced professional when it came to the gaming industry. He acknowledged that entering an established market is going to be challenging and understood the pros and cons of launching the game in such a market. 2. Experience- Bob Reiss had been successful with his last two ventures providing him the necessary experience and strategic vision to start a new business. He was an operations guy with a clear understanding of how products are manufactured for a niche but steady market. He leveraged his experience and successful track record to connect with individuals who could play an influential role for his venture. 3. Realistic Execution- Bob was aware about his strengths and weaknesses from the beginning whether it was funding, resources, etc. When he decided to enter this market, it was very critical for him to execute the strategy for him to make this venture successful and profitable.......

R&R Case Study

...R&R Case Study What factors created an opportunity for Bob Reiss and the “TV Guide Game?” In order for Bob Reiss to be successful with the “TV Guide Game,” he had to be aware of a multitude of factors that would lead to his success. For starters Bob had a background in business from Harvard Business School, one of the most prestigious school in the nation. This business education gave him many key insights into the market and how to conduct a successful business. For example the article cites that when he started his own company he “kept overhead very low, even in good years, and never own or be responsible for a factory.” He had great people skills. This was proven by the fact that he wanted to be paid a low salary and a high sales commission. This is not something that most people ask for when first starting off. He must have been confident in his intrapersonal skills and understanding what people wanted when being sold a product. Bob saw an emerging market, in Canada alone there were 100,000 copies sold of the trivial pursuit game. He knew the market well enough to understand that there were be 10x the sales in the U.S. that would be 1million copies merely starting out. He worked for a couple other companies before starting his own to understand the business and how to build sales. At the time there were not many competitors in the market-space so he was able to act quickly enough before all the major game manufacturers jumped on board. All of these factors......

In the case of PMOs, this position is worthwhile as theories are almost inexistent and the complexity found in the reality cannot be explained using existing simple models and a positivist approach. Just as organisations are complex social entities, so too are the specific organisational project management structures that encompass PMOs. In this perspective, the PMO could be seen as a socially constructed entity that is part of a complex organisational system. Taking this approach will give a completely new vision of the PMO. Instead of having an ad hoc picture we will follow the evolution of this entity along with the evolution of its parent organisation from an historical coevolutionary perspective. Van de Ven [12] proposes the concept of engaged scholarship defined ‘‘as a participative form of research for obtaining the different perspectives of key stakeholders (researchers, users, clients, sponsors, and practitioners) in studying complex problems’’. Inspired by Van de Ven [12], the methodology proposed here brings together the different points of view of key people involved with PMOs using a combination of qualitative and quantitative instruments that permit to uncover some of the......
